This is very important for fish farmers because most farmers do not know the right density or the number of fish to be stocked in a pond.
Many think that they can get a lot of fish by stocking heavily not knowing that each pond has a maximum carrying capacity and once it is overstocked the fish may not die, but it will experience stunted growth and this will automatically kill the market.
Look out for the best variety because this is what determines growth.
Farmers are advised to stock within 10 days after filling the pond with water. Fingerlings weigh between 7-10 grams. 2kgs per square metre for catfish is recommended, while 1kg is recommended for tilapia.
This means that if tilapia weighs 10 grams, you can stock as many as 100 fingerlings in a square metre. On the other hand, if catfish fingerlings weigh 10 grams and you need 2kgs, you stock 200 fingerlings per square metre.
Should I mix tilapia with catfish?
It is not advisable to grow them commercially in the same pond.
However, If you want to control the population of tilapia in a pond, you can drop in a few catfish.
