[0038] 1. Source of broodstock
[0039] The broodstock for breeding is F 2 Substitute anchovy.
[0040] 2. Breeding of broodstock
[0041] ①Static water cultivation in the early stage. Choose a F with a strong physique, good vitality, complete fins and scales, and no injuries or diseases. 2 Generation of backup broodstock, put into an area of more than 6 mu of still water ponds, stocking density is 80 / mu. Live baits such as green shrimps and "red worms" were fed 6 days after the reserve broodstock entered the pond, and the total weight ratio of the bait biomass to the sword anchovy in the pond was kept at 0.02:1. The water quality of the pond should be well managed daily, fresh water should be replaced in time and the aerator should be turned on.
[0042] ②Intensive cultivation of running water in the later stage. In the winter o...
