The same fish stocked in the cages should have the same individual size. In this case, the farmed fish can meet all or most of the criteria for marketing through a breeding cycle.
2, stocking density
The stocking densities are different depending on the stocked species and individual size. In general, the salmon species weighing 75 g to 100 g per stock have a stocking density of 150-200 tails and a body weight of 80 g or 350 g. The species of flower carp, 80g fish species put 450-550 per carton (cage area of ​​28 square meters), 350 grams per carton put 200-250 (net cage area of ​​28 square meters), grass carp specification is 300 - 500 g/tail, with a stocking density of 20-25 tails per square meter.
3, fingerling disinfection
In order to prevent fish species from dying after they enter the tank, they must be disinfected before entering the tank. Usually the economical and practical method is to soak the fish species with 1-4% salt water for 2-10 minutes, killing some of the body surface and Bacteria and protozoa do not use metal dissolvers.
4, cage soaking:
The cages should be soaked for one week before the fishes are put into the box, so that the nets will be given some attachments to make the nets smoother and avoid fish scrape.
5, cage inspection:
Before entering the box, the fish should also check whether there is any hole in the cage, whether the frame is firm and the anchor is firm.
