| DATE | TIME | |
| 02-JUN-2006 | 18:00 | 800ml Vittel non-carbonated bottled water + 26g Artemia salt (=32g/l) |
| 03-JUN-2006 | 11:00 | Added Artemia eggs |
| 04-JUN-2006 | 02:00 | Eggs start to open and the nauplii emerge, but still are in
a protective hull from the egg |
| 04-JUN-2006 | 07:50 | First nauplii have hatched |
| 04-JUN-2006 | 21:00 | Added two drops of liquid algae |
| 05-JUN-2006 | 17:00 | Added two drops of liquid algae |
| 06-JUN-2006 | 12:00 | Water turned a little whitish and some "layer"
formed at the surface. Bacteria explosion ? |
| 11-JUN-2006 | 12:00 | Water got much cleared again over the past 5 days
without any feeding |
| | 20:00 | Added a pottery shard to support algae growth (make sure you
sterilise the shard with boiling water and let it cool, before you add it) - when the shard is completely covered with
algae, and the water is in balance, no feeding or aeration is needed. The algae produce enough oxygene. |
| 12-JUN-2006 | 12:00 | Water turned a little orange'ish due the pottery shard |
| | 18:00 | Added one drop of liquid algae and one aqua leash of fresh water (unloaded
the aqua leash fast to mix oxygen into the tank too) |
| 13-JUN-2006 | 21:00 | There seems to be no visible effect of the "orange
water" on the nauplii - at least all are swimming as usual |
| 15-JUN-2006 | 17:00 | Added some bottled water with the aqualeash and one drop
liquid algae - in 2-3 days I'll start feeding with regular algae powder |
| 16-JUN-2006 | 21:00 | Added a minimal amount of algae powder. The Artemia are growing well,
the water is very clear (with a slightly yellowish color from the pottery shard). |
| 18-JUN-2006 | 19:00 | Added about half a small scoop of algae powder |
| 20-JUN-2006 | 21:00 | Added a minimal amount of algae powder |
| 24-JUN-2006 | 18:00 | Many Artemia are now about 5mm big; their gut is dark
and full, which indicates that there is enough algae food; they like to swim near the pottery shard and scrap it - there
is a little amount of algae powder on the surface of the shard. Added one aqua leash of bottled water |
| 27-JUN-2006 | 21:00 | Added a minimal amount of algae powder |
| 28-JUN-2006 | 21:00 | Added half an aqua leash of bottled water |
| 29-JUN-2006 | 21:00 | Added half an aqua leash of bottled water - adding
oxygen with the water this way, also has the advantage that it raises algae from the bottom of the tank |
| 28-JUN-2006 | 21:00 | About 15 seconds airstone airation; added a minimal amount of algae powder |
| 30-JUN-2006 | 19:00 | Added an aqua leash of bottled water |
| 02-JUL-2006 | 19:00 | Added two aqua leash of bottled water |
| 03-JUL-2006 | 19:00 | Added 3 aqua leash of bottled water |
| 04-JUL-2006 | 22:00 | Some nauplii hatched really late, so I added
3 drops of liquid algae and one aqua leash of bottled water |
| 03-JUL-2006 | 19:00 | About 15 seconds airstone airation; added 2 drops of liquid algae, about half a small scoop
of algae powder |
| 08-JUL-2006 | 11:00 | About 15 seconds airstone airation |
| 09-JUL-2006 | 11:00 | Added 2 aqua leash of bottled water |
| 11-JUL-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 14-JUL-2006 | 19:00 | Added some algae powder and 3 aqua leash of bottled water |
| 17-JUL-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 18-JUL-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 19-JUL-2006 | 23:00 | Added some algae powder and 2 aqua leash of bottled water |
| 22-JUL-2006 | 15:00 | Added 1 aqua leash of bottled water and some Bactozym |
| 27-JUL-2006 | 20:00 | Added 4 aqua leash of bottled water, some Bactozym and algae powder |
| 28-JUL - 10-AUG-2006 | - | Added some bottled water every 3 days or so; the original
population died due some "bacterial explosion" due the Byctozym(?). After the water cleared up again, I added some new eggs
on 05-AUG-2006 and today 10-AUG-2006, many nauplii are still doing fine. There are quite some algae growing on the floor, so
let's see if that is enough for the nauplii. |
| 29-AUG-2006 | 20:00 | After my vacation some "teenages" are still
swimming around. |
| 09-SEP-2006 | 21:00 | After another vacation still some "teenages" are
swimming around. They don't seem to have gained on size, but they are still alive and going strong. NOTE: There was NO
aeration for ONE month. |
| 14-SEP-2006 | 19:00 | Added 3 aqua leash of bottled water to slowly equalize
the evaporated amount |
| 18-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 21-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 22-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water and one small
scoop of algae powder |
| 26-SEP-2006 | 21:00 | Added 2 aqua leash of bottled water |
| 03-OCT-2006 | 21:00 | Added 2 aqua leash of bottled water |
| 07-OCT-2006 | 21:00 | Added 1 aqua leash of bottled water, some algae powder
and 4 drops of "FilterStart" (liquid inactive bacteria) to get rid of the extremely high nitrite and ammonia levels - see
the Water Quality Page |
| 09-OCT-2006 | 12:00 | Added another 4 drops of liquid bacteria |
| 11-OCT-2006 | 23:00 | I spotted one nauplius - either the improving water
quality caused it to hatch, or the slightly higher water level due adding bottled water covered one previously
unhatched egg with water |
| 12-OCT-2006 | 12:00 | Added 2 aqua leash of bottled water |
| 14-OCT-2006 | 12:00 | Added 2 aqua leash of bottled water |
| 16-OCT-2006 | 18:00 | Added 3 aqua leash of bottled water |
| 20-OCT-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 23-OCT-2006 | 19:00 | Added 2 aqua leash of bottled water and one small scoop
of algae powder |
| 28-OCT-2006 | 13:00 | Added 2 aqua leash of bottled water |
| 30-OCT-2006 | 22:00 | Added 2 aqua leash of bottled water |
| 02-NOV-2006 | 18:00 | The 2 males left (from the 09-SEP-2006 population)
in the tank are still going strong. Added 2 aqua leash of bottled water. |
| 06-NOV-2006 | 15:00 | Added 3 aqua leash of bottled water |
| 06-NOV-2006 | 22:00 | Added 2 aqua leash of bottled water and one small scoop
of algae powder |
| 09-NOV-2006 | 22:00 | Added 2 aqua leash of bottled water |

| 13-NOV-2006 | 22:40 | Added 2 aqua leash of bottled water |
| 14-NOV-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 15-NOV-2006 | 23:00 | Surprise! Surprise! The second male is
actually a female - didn't pay attention to the antennae before and she had no full egg sac until now. Also
added 2 aqua leash of bottled water |
| 17-NOV-2006 | 00:00 | Added 2 aqua leash of bottled water and one drop
of liquid algae |
| 18-NOV-2006 | 15:00 | Added 2 aqua leash of bottled water |

| 23-NOV-2006 | 23:00 | Added 1 aqua leash of bottled water |
| 24-NOV-2006 | 19:00 | Added 1 aqua leash of bottled water and
one small scoop of Spirulina powder. |
| 26-NOV-2006 | 02:00 | Added 1 aqua leash of bottled water |
| 26-NOV-2006 | 14:00 | Added 1 aqua leash of bottled water |

| 09-DEC-2006 | 21:00 | Added 1 aqua leash of bottled water |
| 10-DEC-2006 | 19:00 | Added 1 aqua leash of bottled water |
| 12-DEC-2006 | 20:00 | Added 1 aqua leash of bottled water |
| 15-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water |
| 21-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water |
| 22-DEC-2006 | 22:00 | Added 2 aqua leash of bottled water |
| 23-DEC-2006 | 12:00 | The one female is still very happy in the
tank (the last time I added eggs to this tank was on 10-AUG-2006, so this female is at least 130 days old (~4 month).
Water test: ammonia/ammonium level: ~2.0mg/l - this is actually an excellent value. Nitrite level: >30mg/l - this is
surprising, since the ammonia/ammonium level is quite low. |
| 23-DEC-2006 | 13:00 | Added 1 aqua leash of bottled water |
| 05-JAN-2007 | 17:00 | Over the past few days a rather thick
layer of white stuff (bacteria?) accumulated at the surface of the water. The last remaining adult seems to have died,
but I spotted a metanauplius about 2 weeks old. |
| 05-JAN-2007 | 22:00 | Removed the layer of white stuff (bacteria?)
and replaced about 0.25l of the water |
| 07-JAN-2007 | 22:00 | Added 1 aqua leash of bottled water.
Population is up to 2 again - I guess some eggs from the walls were put into water again due the water change. |
| 11-JAN-2007 | 23:00 | Added 2 aqua leash of bottled water
and 2 drops of liquid algae for the new Artemia. |
| 15-JAN-2007 | 20:00 | Added 2 small scoop of Dunaliella
algae carotene extract from from cognis.com to test if carotenes are the major reason for the red color of the Artemia
in the Salina di Cervia. |
| 17-JAN-2007 | 13:00 | Added 2 aqua leash of bottled water |
| 20-JAN-2007 | - | Added 2 aqua leash of bottled water |
| 23-JAN-2007 | 05:30 | Added 3 small scoops of Dunaliella carotenoids |
| 24-JAN-2007 | 23:30 | Added 2 aqua leash of bottled water |
| 25-JAN-2007 | 23:30 | Added 2 aqua leash of bottled water |
| 26-JAN-2007 | 20:30 | Added 2 aqua leash of bottled water |
| 29-JAN-2007 | 23:00 | Added 2 aqua leash of bottled water |
| 30-JAN-2007 | 23:00 | Added 2 aqua leash of bottled water and
1 big scoop of Dunaliella carotenoids |
| 31-JAN-2007 | 23:00 | Added 2 aqua leash of bottled water |
| 11-FEB-2007 | 22:00 | Well, the last amount of Dunaliella carotenoids
was too much and the 2 remaining adults died. But today I spotted some nauplii probably 3 days old.
Added 1 aqua leash of bottled water |
| 01-MAR-2007 | 23:00 | Without feeding and adding evaporated
water (+oxygen) there is now one adult female (~13mm), about 5 "teenages" with a size from 5m to 7mm and some
metanauplii. They are all very pale - no sign of redish coloration due the carotenoids or lack of oxygen. |
| DATE | TIME | |
| 08-JUL-2006 | 11:00 | 800ml Vittel non-carbonated bottled water + 26g Artemia salt (=32g/l) |
| 08-JUL-2006 | 18:00 | Added Artemia eggs (eggs covered a circle
of about 2cm in diameter on the surface of the water) |
| 09-JUL-2006 | 08:00 | A few eggs start to open and the nauplii emerge, but still are in
a protective hull from the egg |
| 09-JUL-2006 | 11:00 | First nauplii have hatched |
| 11-JUL-2006 | 14:00 | Added two drops of liquid algae |
| 11-JUL-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 14-JUL-2006 | 19:00 | Added two drops of liquid algae and 3 aqua leash of bottled water |
| 17-JUL-2006 | 20:00 | Added two drops of liquid algae and 2 aqua leash of bottled water |
| 18-JUL-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 19-JUL-2006 | 23:00 | Added some algae powder and 2 aqua leash of bottled water |
| 22-JUL-2006 | 15:00 | Added 1 aqua leash of bottled water and some Bactozym |
| 27-JUL-2006 | 20:00 | Added 2 aqua leash of bottled water and some algae powder |
| 28-JUL - 10-AUG-2006 | - | Added some bottled water every 3 days or so; there
is a little algae "carpet" on the floor of the tank and that seems to be sufficient to feed 3 adult Artemia. Nevertheless
I added some algae powder. |
| 29-AUG-2006 | 20:00 | Back from my vacation I found the tank empty.
No surprise. But I used the remaining water to quickly move many adult females from the Saline of Cervia/Italy from
a water bottle to the existing water. The salt content of the water from the saline was obviously too high for the adults, since they had
troubles diving to the bottom of the bottle and the dead Artemia floated on the surface (which they never do in
my regular tanks). |
| 30-AUG-2006 | 20:00 | All adults are still alive (no dead Artemia on
the bottom) - the tank was not aerated the past 20(!) days and I didn't yesterday and today |
| 30-AUG-2006 | 21:00 | Moved some of the saline water of tank #3 (half an aqua leash)
to establish a beneficial bacteria colony here aswell |
| 03-SEP-2006 | 21:00 | Many nauplii are swimming around (life birthing confirmed) |
| 09-SEP-2006 | 21:00 | Some nauplii are still swimming around,
but most of the Nauplii as of 03-SEP-2006 didn't survive most likely due low oxygen content. But *all* adults are still
going strong. |
| 14-SEP-2006 | 19:00 | Added 3 aqua leash of bottled water to slowly equalize
the evaporated amount |
| 18-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 21-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 22-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water and one small
scoop of algae powder |
| 26-SEP-2006 | 21:00 | Added 2 aqua leash of bottled water |
| 03-OCT-2006 | 21:00 | Added 2 aqua leash of bottled water |
| 03-OCT-2006 | 21:00 | All adults have a much more pale color now, meaning
that they almost lost the original very red color as they have in the Salina di Cervia. Maybe this is due
the lack of the red Dunaliella algae, which is abundant in the saline or another reason might be the much lower
salinty in this tank than in the saline. |
| 04-OCT-2006 | 23:00 | Added 1 aqua leash of bottled water |

| 09-NOV-2006 | 22:00 | Added 2 aqua leash of bottled water |
| 10-NOV-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 11-NOV-2006 | 21:00 | Added 3 aqua leash of bottled water - spotted
3 metanauplii in the tank - hooraaay! :-) It seems that the daily water additions have provided the necessary
oxygen to ensure live birth and also of course lowered the salinity to signal to the females that the "pond"
is not drying out anytime soon, so they switched to live birth, instead of making eggs (which need to dry
before they can hatch). By the way, I switched to daily water additions of 1 aqua leash a day since the
heating period began in my flat, therefore water evaporation in the tanks increased and more water addition per day was
needed. |
| 13-NOV-2006 | 22:40 | Added 2 aqua leash of bottled water |
| 14-NOV-2006 | 19:00 | Added 2 aqua leash of bottled water - about 10-15
nauplii and metanauplii are now swimming around - also added 1 drop of liquid algae for the newly born Artemia |
| 15-NOV-2006 | 23:00 | Added 2 aqua leash of bottled water - the youngsters
are still going strong |
| 17-NOV-2006 | 00:00 | Added 2 aqua leash of bottled water |
| 18-NOV-2006 | 15:00 | Added 2 aqua leash of bottled water |

| 21-NOV-2006 | 18:00 | Added 1 aqua leash of bottled water |
| 22-NOV-2006 | 18:00 | Added 1 aqua leash of bottled water,
one scoop of algae powder, and one drop of liquid algae. There are about 10-15 descendants of the original
Cervia Artemia in the tank right now. By the way, all adults are pretty pale now, almost white, but 1-2 still
show a slightly red coloring. |
| 23-NOV-2006 | 23:00 | Added 1 aqua leash of bottled water |
| 24-NOV-2006 | 19:00 | Added 1 aqua leash of bottled water |
| 26-NOV-2006 | 02:00 | Added 1 aqua leash of bottled water |
| 26-NOV-2006 | 14:00 | Added 1 aqua leash of bottled water |

| 28-NOV-2006 | 16:00 | Added 1 aqua leash of bottled water |
| 29-NOV-2006 | 19:00 | Added 1 aqua leash of bottled water -
just spotted a "super-pregnant" female which has with many eggs in the ovaries, a full brood pouch
and even one egg (to be live birthed ?) in the exit of the brood pouch. I also added 2 drops of liquid algae -
both the newly born Artemia and the adults feed from the liquid algae. |
| 02-DEC-2006 | 19:00 | Added 1 aqua leash of bottled water -
all Artemia are very pale now |
| 03-DEC-2006 | 19:00 | Added 1 aqua leash of bottled water - the population
is now up to about 10 animals :-) |
| 04-DEC-2006 | 20:00 | Added 1 aqua leash of bottled water |
| 05-DEC-2006 | 23:00 | Added 1 aqua leash of bottled water |
| 06-DEC-2006 | 18:00 | Added 1 aqua leash of bottled water and
one small scoop of algae powder |
| 07-DEC-2006 | 02:00 | Added 1 aqua leash of bottled water -
there are now 10 very active adults in the tank - most likely 3 original adults from the Salina di Cervia, and 7
offsprings. They swim very actively to the ground and scrape off algae from the ground. All have a very dark
gut. Also some nauplii are swimming arounf again. |
| 08-DEC-2006 | 20:00 | Added 1 aqua leash of bottled water |
| 09-DEC-2006 | 21:00 | Added 1 aqua leash of bottled water |

| 12-DEC-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 14-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water.
Also did some water tests: Nitrite NO2: 0.3mg/l ; Ammonia NH3/NH4: 3.0 mg/l
While the water in the "oxygen-test-tank" at the end had levels of
Nitrite NO2: <0.3mg/l and Ammonia NH3/NH4: off scale: >>5mg/l , the levels in this
non-constantly aerated tank, going for a much longer time, have better values. On the other hand, much more
dead Artemia have contaminated the oxygen-test-bottle, so this might explain the much higher ammonia level. |
| 15-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water |
| 16-DEC-2006 | 14:00 | Tested the pH value: 8.4 pH which is very
close to the optimum of 8.5-9pH |
| 16-DEC-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 17-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water and
one drop of liquid algae for the new nauplii. Also removed one dying adult (floating on the surface in U-shape and barely
moving the swimming appendages) for microscopy. |
| 18-DEC-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 19-DEC-2006 | 20:00 | Added 2 aqua leash of bottled water |
| 20-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water |
| 21-DEC-2006 | 23:00 | Added 2 aqua leash of bottled water |
| 22-DEC-2006 | 08:00 | Found one dead Artemia female floating
on the surface, so I removed it to avoid further water contamination with ammonia/ammonium due the decay process. |
| 22-DEC-2006 | 22:00 | Added 2 aqua leash of bottled water |
| 23-DEC-2006 | 13:00 | Added 3 aqua leash of bottled water |
| 26-DEC-2006 - 04-JAN-2007 | - | Added 1-2 aqua leash of bottled water daily |
| 05-JAN-2007 | 17:00 | Added 8 aqua leash of bottled water,
also removed the "skin" (layer) atop the water, which accumulated over the past few days. I think that is another
baterical "explosion". |
| 05-JAN-2007 | 23:00 | Added another 10 aqua leash of bottled water |
| 06-JAN-2007 | 21:00 | Added 10 aqua leash of bottled water.
The reason for the massive water additions the yesterday and today is to restore the original (lower) salinity in the tank
and see if that triggers reproduction. |
| 07-JAN-2007 | 22:00 | Added 10 aqua leash of bottled water
and a drop liquid algae. I spotted serveral fresh born nauplii :-) Either life-birthing has indeed started again
or some eggs from the walls were put into water again due the water change. Since there are almost no eggs visible near
the surface on the walls, floating or in the water, I think the amount of nauplii will tell if life-birthing has
started. The salinity dropped rather dramatically (compared to previous water refills), so the females will now
think the "pond" is good for many nauplii, since it won't dry up in the near future - so the nauplii can mature
and reproduce. |
| 08-JAN-2007 | 22:00 | Added 2 aqua leash of bottled water |
| 09-JAN-2007 | 22:00 | Added 2 aqua leash of bottled water.
Plenty of fresh hatched/born nauplii visible. |
| 10-JAN-2007 | 22:00 | Added 2 aqua leash of bottled water
and one drop of liquid algae. The adults have those white threads (excrement) behind them, which shows that they
are healthy and feed well. |
| 11-JAN-2007 | 21:00 | Added 2 aqua leash of bottled water. |
| 12 to 16-JAN-2007 | - | Added 2 aqua leash of bottled water
daily. |
| 17-JAN-2007 | 15:00 | Added 2 aqua leash of bottled water
and one drop liquid algae and one small scoop of algae powder. |
| 18 to 22-JAN-2007 | - | Added 2 aqua leash of bottled water each day |
| 23-JAN-2007 | 10:00 | Many fresh born nauplii are swimming around.
All 3 adult females have full egg sacs (brood pouches). So this strongly supports my theory that quickly rising the
water level (=> decreasing salinity) starts live reproduction, since the females assume that the "pond" doesn't dry out anytime soon
since the salinity is decreasing and it's safe for the offsprings. I think we can exclude that the nauplii are
from some eggs on the surface, since there are so many of them, low egg count on the border on the surface and those
eggs on the surface would have hatched much earlier. Also, as said earlier, the females have full brood pouches.
Added one drop of liquid algae and 2 aqua leash of bottled water. |
| 24-JAN-2007 | 23:00 | Added 2 aqua leash of bottled water |
| 25-JAN-2007 | 23:20 | Added 2 aqua leash of bottled water,
one drop of liquid algae and 1 small scoop algae powder. |
| 26-JAN-2007 | 20:00 | The tank is now blooming of life :-)
The 3 adult females seem to be very healthy (dark gut; full brood poushes) and there are plenty of kids swimming around.
The biggest kids are about 3-4mm - there are also plenty of metanauplii. Added 2 aqua leash of bottled water |
| 27-JAN-2007 | - | Added 2 aqua leash of bottled water |
| 28-JAN-2007 | 14:00 | Added 2 aqua leash of bottled water and
2 drops of liquid algae, since there are so many metanauplii. |
| 29-JAN-2007 | 01:00 | Current tank statistics:
About 50 metnauplii (size ~2mm); 3 with ~4mm; 1 with ~6mm; 3 adults with dark/black guts |
| 29-JAN-2007 | 23:00 | Added 2 small scoops of algae powder
and added 8 aqua leash of bottled water |

one small scoop of algae powder. |
| 07-FEB-2007 | 16:00 and 22:00 | Added 1 aqua leash of bottled water.
Statistics: 3 adults (~15mm); 3 adults (~12mm); about 30 with sizes from 3mm to 7mm. The bigger ones show some faint red
coloration, due the lower oxygen content of the water (more haemoglobin in the blood of Artemia) as in the water
of the salinity experiment. The salinity experiment tank is constantly aerated and the two adult Artemia are pale. |
| 08-FEB-2007 | 08:00 | Added 1 aqua leash of bottled water. |
| 08-FEB-2007 | 23:30 | Added 1 aqua leash of bottled water and

| 10-FEB-2007 | 10:00 | Added 1 aqua leash of bottled water. |
| 10-FEB-2007 | 23:00 | Added 1 aqua leash of bottled water and
one small scoop of algae powder. All is going very well - the tank is really crowded. |
| 11-FEB-2007 | - | Added 1 aqua leash of bottled water in the morning
and in the evening and one small scoop of algae powder. |
| 12-FEB-2007 | - | Added 1 aqua leash of bottled water in the morning
and in the evening and one small scoop of algae powder. |
| 13-FEB-2007 - 18-FEB-2007 | - | Added 1 aqua leash of bottled water in the morning
and in the evening |
| 17-FEB-2007, 18-FEB-2007 | - | Added one small scoop of algae powder. |
| 19-FEB-2007 - 27-FEB-2007 | - | Added 1 aqua leash of bottled water in the morning
and in the evening. |
| 28-FEB-2007 | 22:00 | Replaced about 1/4 liter of water. Also
removed the gunk at the bottom with the new 10ml pipette. Added two small scoop of algae powder. |
| 01-MAR-2007 | 23:00 | Removed some remaining old algae and gunk which
accumulated in one corner over the past day. The Artemia are very active on the bottom of the tank, hence the algae at the
bottom is usually mixed up into the water again. Current statistics: 7 animals 10-15mm; ~20 animals ~5-7mm |
| 03-MAR-2007 | 18:00 | Added two small scoop of algae powder and
2*5ml fresh water with a pipette. |
| 09-MAR-2007 | - | Added one small scoop of algae powder |
| 09 - 16-MAR-2007 | - | Added 5ml fresh water with a pipette
twice a day |
| 17-MAR-2007 | - | Added 10 * 5ml fresh water with a pipette to
compensate water evaporation which was not covered the past days. Current statistics: about 4 animals 10-15mm; ~20 animals
smaller than 10mm. In the past past week they got a lot more red than they used to be after getting pale after Cervia,
so I blame this on the lack on oxygen which has been prevented to get into the water by surface by a bacteria carpet
which has formed on the surface. The carpet was removed today almost entirely. |
| DATE | TIME | |
| 29-AUG-2006 | 20:00 | This tank in entirely based on half a liter of
water from the Saline of Cervia / Italy, containing 7 adult females and a few youngsters. Let's see how this
works out - I'm very confident that this culture will last much longer than the "fresh" tanks, since there
are plenty of beneficial bacteria in the water of the solar salt work. |
| 09-SEP-2006 | 21:00 | Without aeration for 11 days now *all* adults
are still alive and swimming happily around. Almost no "youngsters" are visible now, again, that means that
Artemia before the adulthood need much more oxygen than adult Artemia.
|
| 14-SEP-2006 | 19:00 | Added 3 aqua leash of bottled water to slowly equalize
the evaporated amount |
| 18-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |
| 21-SEP-2006 | 19:00 | Added 2 aqua leash of bottled water |

| 03-OCT-2006 | 21:00 | In contrary to tank #2, the adults in this
tank still have the bright red color. This may be due the original saline water, which indeed might contain
enough red Dunaliella algae to make them red. Low oxygen content can be most likely ruled out, because for
more than one month airation (by adding new bottled water with the acqua leash) has been the same as with tank #2. |
| 04-OCT-2006 | 23:00 | Added 1 aqua leash of bottled water.
One offspring (about 3-4mm in length) in this tank with original water from the salina (hence with maybe some culture of
Dunaliella, the red algae) has also a very red color, so that may be a hint for Dunaliella causing
the red color. |
| 06-OCT-2006 | 19:00 | Today I tested the water for nitrite
and ammonia. Ammonia: >5mg/l; Nitrite: ~0.3mg/l. 5 adults are remaining of the original 7+ population. |

3 adults are remaining of the original 7+ population. All 3 are mostly swimming close or at the surface, most likely due
the high salinity. Sometimes they swim down to the ground to scrape off algae from the ground. My next test with
a tank with a salinity of 100g/l or higher will probably finally show if high salinity only (without the red Dunaliella algae)
can be responsible for the red color (raised haemoglobin levels in the blood of the Artemia due the high salt content and
therefore low capability of the water to hold dissolved oxygen). |
| 08-DEC-2006 | 18:00 | Added 1 aqua leash of bottled water |
| 09-DEC-2006 | 18:00 | Added 1 aqua leash of bottled water |
| 11-DEC-2006 | 22:00 | I just discovered that the last 3 adults
also died. The water was getting quite cloudy the past few days, so I assume a bacterial infection was the cause.
I most likely assume that the nearby, recently quite infected (with white stuff (bacteria?)) tank, was the cause
for cross-over contamination. But also another reason can have lead to the death of the last Artemia, but still
the cloudy water leads to a bacterial contamination. So long, my dear friends, it was a pleasure! Meet ya'll
next year in Italy! *end*
