Abstract

The invention relates to the method for converting pomfret larva biological bait into pellet feed. The method comprises the following steps that according to the larva oral fissure width, the best pellet feed feeding time starting point is determined, and starting from the pellet feed feeding time starting point, opening mixed feed accounting for 2% the wet weight of fresh bait is mixed into the wheel animalcule fresh bait; at the 15-day-old to 25-day-old age, the addition proportion of the opening mixed feed is increased by 0.5 time on the basis; at the 26-day-old to 35-day-old age, the addition proportion of the opening mixed feed is increased by one time on the basis; at the 36-day-old to 45-day-old age, the addition proportion of the opening mixed feed is increased by 2 times on the basis; at the 46-day-old to 55-day-old age, the addition proportion of the opening mixed feed accounts for 50% of the daily intake bait mass ratio; at the 56-day-old to 60-day-old age, only the opening mixed feed is fed. The conversion efficiency of the pomfret larva biological bait into the pellet feed can be improved, and finally the pomfret larva cultivating survival rate can be increased.

Description

technical field

[0001] The invention belongs to the technical field of feed transition for silver pomfret seedlings, and in particular relates to a method for transitioning silver pomfret juvenile fish biological bait to granular feed. Background technique

[0002] Silver pomfret is one of the main seawater economic fishes in the coastal areas of my country. In recent years, the artificial breeding of silver pomfret has been realized in China, and its artificial breeding technology is also being continuously improved. Therefore, silver pomfret is a very potential new aquaculture target in the future. In view of its high nutritional value and large market demand, its development potential is great.

[0003] At present, in the artificial breeding of silver pomfret, the survival rate of larvae and juveniles is relatively low, which is also one of the main factors limiting the large-scale industrial promotion of silver pomfret. There are two main reasons for the low survival ra...
