Problems solved by technology

In Jiangsu, Zhejiang and other places of our country, black sea bream is generally cultured in ponds. However, due to the limitation of natural conditions, the effective growth period of black sea bream is relatively short. Generally, it takes 3 years to be on the market, and it needs to go through 2 long wintering periods. high cost

Embodiment 1

[0024] The present embodiment provides a kind of method that prolongs the growth period of black sea bream, specifically as follows:

[0025] 1. Prepare to transfer the overwintering black bream outdoors when the water temperature in the outdoor pond is stable above 8°C. Use brackish water or fresh water (water quality conforms to the provisions of GB 11607) to adjust the salinity of the pond water to 10-15‰ before putting fish species in the pond.

[0026] 2. Domesticate the salinity of the overwintering black sea bream species one week before they are transferred to the outdoor pond: discharge part of the seawater in the overwintering pond, add brackish water or fresh water, adjust the salinity of the pond water to 10-15‰, and gradually adjust it to Target salinity, 1 day apart. After the adjustment is completed, the fish are adapted to the new salinity for 5 days, and no bait is cast or water is changed during the adjustment period.

[0027] 3. After the black sea bream i...

Abstract

The invention relates to a method for prolonging the growth period of black sea bream. A salinity regulation manner is adopted to improve the temperature tolerance capability of the black sea bream, and thereby prolonging the growth period of the black sea bream, so that the method is easy to operate and strong in feasibility.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a method for extending the growth period of black sea bream. Background technique [0002] Black sea bream (Sparus macrocephalus) belongs to the order Perciformes, the family Sparidae, and the genus Sparus Linnaeus. It is mainly distributed in the southeast coast of my country, Japan, Southeast Asia and other countries and regions. Black sea bream is a rare and valuable economic fish cultured in coastal areas of my country. The meat is delicate and delicious, and the nutrition is very rich. It is very popular in the market and consumers. The price of black sea bream with a size of about 500g is generally more than 60 yuan / kg, and the economic value is relatively high. my country's Jiangsu, Zhejiang and other places generally breed black sea bream in ponds. However, due to the limitation of natural conditions, the effective growth period of black sea bream is short, and it usually tak...
