it depends on the system used in raising them... If u use a flow through system it is 100 to 150 fishes per square metre. Recirculatory is 300 per square metre, earthen pond is 50 per square metre..

The 2000ltrs will contain 250 to 300fishes to maturity not 400 to 500.

Litre is a measure of volume whereas sqm is the measure of area. There is nothing in common between the two or It is kind of like asking how many liters of water fit on a floor tile. The question cannot be answered numerically accurately.

But I gave you the answer, because I practice what am saying, I have those tanks in varieties from 4000ltrs to 1200ltrs, so you should know what I mean.

If it is a flow through system, you don't need to change water through out. As for the treatment, you only need to pour salt into the pond if you want to but it is optional anyway. I don't use any vaccination before stocking though
Re: Hidden Truths About Catfish Business!!! by ab1x: 8:29pm On May 27, 2013
2000 liters of water for 400 to 500 pieces can only rear Melange. If it exceed 3 months, it will lead to over crowding and overcrowding will affect the growth of fish. I don't really like getting myself mixed up with the size of pond and how many fish it can take. I can only say when I see it, for example 30ft breath by 40 ft length earthen pond can conveniently rear 2000 pieces of fish, 20ft by 50 ft can also rear 2000 pieces etc.

@robonski thanks for ur good work. What shd be d likely mortality rate for juvenile of 1000 fishes under good mgt practices.

omode2: @robonski thanks for ur good work. What shd be d likely mortality rate for juvenile of 1000 fishes under good mgt practices.

management practices differs from farm to farm.. I record different mortality rate with the same management practices at different stocking,though minimal.. But the least i have recorded was 4 death out of 3000 juvenile for 5 month.. I guess u should give them good management and find out on your own.. Thanks

Mortality rate in earthen pond is minimal compare to concrete pond because we hardly change water from inception to the point of sales. Much a times when u change water in concrete pond, it is always stress for the fish. It also can inflict wound on their body thereby leading to their death because other fish will be pecking them. Other things that can lead to the death of fish in earthen pond among others are; snake, crab, frog, toad etc but with the aid of net one can control such. However, everything boils down to good management practices and that depends largely on experience.

Get salt and foam or sack, and wash the pond, and get back to us with ur feedback, then if they are still dying you have to treat your fish.

@ab1x my oga at the top I hail oooo, @saheed, fine 1 or 2 fish will die, but it shouldn't be on a daily basis, and fine all the drugs you mention there is fine, but there are some drug produced for fish which you can use. I will advise you still wash your pond with salt.

@ aquatic thank u, @ excelsior... my fish are 6 weeks and 2 days i formulates their feed and i change water every 3rd or 4th day. tarpaulin pond size is 8x8=210, 8x8=260 (and also tell me how many can my pond stock till table size 8ft x 8ft x 3.5ft). how should i apply the tetracyclin and @aquatic would i move them out if i want to rewash the tarpaulin (though this is my second stockin o not first).
