Embodiment 1

[0015] A parent breeding method for silver pomfret, including preparation of breeding pool, selection of parent body, feeding, regulation of spawning, and daily management, specifically:

[0016] 1) Preparation of cultivation pool: choose a circular indoor cement pool with a diameter of 7m and a depth of 1.5m as the cultivation pool. A culvert with a diameter of 40cm is installed in the center of the bottom of the pool, and the cultivation water body is 30m. 3 , water temperature 20 ℃, salinity 23‰, pH value 8, dissolved oxygen > 5mg / L, daily exchange capacity > 900%, fixed lighting for 13 hours a day, sewage once a day, keep the cultivation water clean, use black plastic around the cultivation pool Covering the broodstock to avoid disturbing the broodstock can provide a good living environment for the broodstock, and can give the broodstock a stimulating signal to promote the pituitary gland to secrete gonadal hormones and promote the development of the gonads;

Abstract

The invention discloses a pampus argenteus parent culture method. The method comprises the steps of culture pool preparing, parent selecting, feeding, spawning regulation and control and daily management and specifically, water of each culture pool has the volume of 25m<3> to 30m<3>, the water temperature of 18 DEG C to 24 DEG C, the salt content of 2.2% to 2.6%, the pH value of 8 to 8.5, the dissolved oxygen of higher than 5mg / L and the daily exchange capacity of higher than 900%, and the daily fixed lighting time is 13 to 15 hours; the ratio of selected female pampus argenteus parents to selected male pampus argenteus parents is 1: (3 to 5); fixed-point quantified feedstuff feeding is carried out once or twice every day, and the feeding amount is 3% to 5% the weight of fish; and agents are injected 36 to 48 hours before the spawning of the parent fish. The method has the beneficial effects that a good living environment can be provided for the parent fish, nutritional ingredients required for growth and development can be provided for organisms, the reproductivity of the parent fish is improved, the amount of spawned eggs of the parent fish and the fertilization rate and hatching rate of ova are increased, the survival rate of larval fish is increased, and the disease resistance is improved.

Description

technical field [0001] The invention relates to the field of fish culture, in particular to a method for cultivating a silver pomfret parent. Background technique [0002] Silver Pomfret (Pampus argente) belongs to Perciformes, Pomfretidae, Pomfret genus. It is an offshore warm-tempered fish. It grows fast, has a large body, and has tender and delicious meat. It is loved by consumers and has high economic value. The southern part of the Yellow Sea and the northern part of the East my country Sea are more concentrated, namely Lusi fishery and Zhoushan fishery. The breeding season of silver pomfret is generally from April to June every year. The spawning grounds are mainly located in rivers with a water depth of 10-20m and a salinity of 26‰-31‰ In the estuary and offshore areas where nutrients and plankton are rich, the sexual maturity of silver pomfret is based on the full anniversary. About 90% of the fish reach sexual maturity at the age of one week, and all fish at two ages ...
