Merci,mon ami :D
And next spawn hatched in the 4th night,in the tank! :o
The weather is warming up,and interval between spawns is moving from 7 to 6 days,and hatching night from 5th to 4th.

Larval run #2 feeding well on Algamac enriched bs.19 DPH and some are dying,1-2/day. :?.Large larvae!
Run #3 started with Artemia at 10 DPH,but don´t seem to be eating it.They are smallish and I remove some dead ones everyday;they were so many that perhaps were underfed. :?

Keep going, it gets better from batch to another.



Indeed,run #2,at 22 DPH,while not perfect,is doing better than #1.One larva is found dead every morning :( .But they are large,getting purplish and 5 have settled to the bottom.I have about 15 larvae.
Settling is a long process in dotties.I´m offering some non living food,but I can´t say they are taking any.
Run #3,at 14 DPH,is smallish and possibly underfed,still presents heavy mortality.19 yesterday,11 today.They are slowly taking to enriched bs,now most of them are feeding on them.But many larvae are in this run 8)

Run #2,23 DPH:Again one dead in the morning,always among the larger :?
I provided some PVC shelters and several took to it,though still in their faint lavender shade.
Nutramar Ova was offered,but not clearly taken.

Run #3-15 DPH.5 dead today,sort of an improvement :roll:
Most (but not all) are feeding on inst.II bs.

I don´t know,adult full size,I guess :?
Run#2-25 DPH.
Three more died,but in the afternoons,not during the night.Somehow,enriching bbs has improved,though not solved the DOA problem. :?
Only few remain pelagic.Settled fish became suddenly shy and remain hidden in their pipes.One exited for a moment showing clear purple colour with the facial mark.So this is META,at 24DPH! 8)
Which doesn´t mean they are safe yet :| I insist in giving Oto B1,in the hope that they will start to take it and improve the nutritional condition.

Run#3-17 days.
Mostly well,many larvae.5-8-6 dead in the morning.But here the smaller,less developed larvae die,while in previous runs the opposite happened.

Run #2-27 DPH.
No more deaths.Only two small larvae remain unsettled.Some of the purple juvs begin to leave the pipes and explore their surroundings,with aggressive displays to each other.

Run#3-19DPH.
14 dead were found yesterday :evil: .Too many and too early for DOA. :? .Treated with antibiotics,just in case.
It worked!.No more deads today! 8)

Hi Luis,

What are you using for antibiotics? I'm currently using neomycin.

Larry,I´m currently using erytromycin.At MACNA Matt-Witt.told me they also are using it at the Rising Tide :wink:

It did not :evil: Dead larvae were found later in the PM.
So Run #3,at 22 DPH keeps paying a daily toll of 5-20 dead larvae.None has started to colour up nor settled.
Larval Run #2,at 30 DPH is almost ended.Only one pelagic larva remains.All the rest ;10-15 purple juvs are Ok.No more casualties 8)

Run #2 has ended.last larva settled.So larval time takes from 20 to 30 days.Juveniles grow steadily,and I am starting with C1 TDO.
Run #3-24 DPH-9 dead yesterday,13 today.Settling begins.

I do know that my hatch rates severely decrease if my nitrate is above 10 mg L-1. Do you keep that under control?


Late reply but I only now got a nitrate test kit. :oops:
This system is at 20 ppm NO3-,which is fairly good,considering that I do nothing about it... :?

Two survivors is two more than I had at my first try. ;)

Next time you'll get 10, then 30, then 100.

Something prophetic in your words! :wink:
Run #2 produced 14 juvs! :D
And run # 3 is still plentiful.

Some larger individuals of the last run (#3) ended meta at 30 dph.
But there are still many larvae,some very small.It will take a while for this run to be finished.Overall,this run is slower than #2,probably due to some initial underfeeding. :?
They are currently under antibiotic therapy and yet I have to siphon out two dead ones every day.

Viel Glück und nicht aufgeben.

Derwins,
Merci :D
Oui,tous ont les memes pere et mere.

Miguel,
Obrigado demais!
Acho que o Algamac foi importante pra atingir esse melhor resultado.

Sylvio,
Viel Dank!
Und wie gehts der ZML?

Isn´t MOFIB truly international? :D
Run #3 at 39 dph has most of them gone thru meta.Still some keep dying,but it will be a great run.I am not sure wether mortality is due to lack of HUFA or bacteria. :?
Other than that,Pseudo.larvae are strong,large and fast growers.

Run #3 has officially ended at 47 DPH.The few small larvae remaining have either died or settled.
100 juvs were moved to grow out.Some few remain in the BRT. 8)

Hallo Luis

Eigentlich bin ich ja ein Gegner von Antibiotika in der Fischzucht.
Aber um die Eier zum Schlupf zu bringen lasse ich mich überreden.

Nimmst du auch dieses hier?
