Artificial Domestication Techniques of Wild Broodstock of Penaeus Hastelloyus

Abstract

The invention discloses a parapenaeopsis hardwickii wild parent shrimp artificial domesticating technology. A cement pool is used for rearing wild parent shrimps temporarily and domesticating the wild parent shrimps. The technology is characterized in that yellow sand of 10 cm is laid on a half area of the bottom of the cement pool, a shading film is covered on an upper opening of the cement pool, and air heads are arranged inside the pool with the density of a half air head per square meter; the cement pool is washed and disinfected before rearing, and the pool is dried for 2-3 days before usage; during temporary rearing, the water level of the pool is 50 cm, the rearing density is 8-15 shrimps per square meter, the salinity of water for rearing shrimps is 25-30, and the temperature of the water is 25-29 DEG C; the shrimps are reared for two times every day, the total feeding amount is 5%-8% of the weight of the shrimps every day, conditions of ingestion, moving and ecdysis of the shrimps are observed every day, dead shrimps are eliminated timely, when the amount of dead parent shrimps are stable, pool replacement is achieved, by now, a normal domesticating period begins, the water level is 80-100 cm, bottoms of sand-free areas are washed every day, water is changed once every week, after the shrimps are domesticated for 15-20 days, the wild parent shrimps can eat feeding baits, and the food intake is 3%-6% of the weight of the shrimps every day.

Description

technical field [0001] The invention relates to aquaculture, in particular to the artificial domestication technology of the wild broodstock of the imitation prawn. Background technique [0002] Hardwick's imitation prawn (Parapenaeopsis hardwickii), commonly known as striped shrimp, slippery shrimp, and choked shrimp, belongs to the decapod order, the prawn family, and the genus Penaeus. It is a warm-water shrimp near the coast. It is distributed in India, Malaysia, Singapore, Japan and the Yellow Sea of ​​my country. In the sea south of the south, it grows on the seabed within 70 meters from the shore. [0003] Hardwood's imitation prawns are fresh and tender, and can be eaten fresh or made into sea rice, which is very popular among people. At the same time, the imitation prawn is the main species of coastal towed shrimp and one of the main economic shrimps in the offshore. [0004] The imitation prawn has fast growth, long breeding period, large population and high econo...
