Artificial culture method for bastard halibuts

Abstract

The invention discloses an artificial culture method for bastard halibuts. The artificial culture method comprises the following specific steps: (1) selecting an inner bay with smaller stormy waves and abundant fish baits; (2) selecting uniform specifications of offspring seeds with the overall length of more than 8 cm and the color and luster of approximately natural fish body color, and rejecting black and white individuals; (3) putting 800 bastard halibuts in every square meter at the beginning, wherein 15 bastard halibuts are put in every square meter when the weight of each bastard halibut is 800g, and the coverage rate of a stocking area is 80%-90% in a common water pool; (4) feeding by using trash fish, feeding four to six times every day in a young fish period, feeding three to four times every day when the weight of each bastard halibut is about 100g, and feeding twice every day when the weight of each bastard halibut is 400 g; (5) feeding after the separation of the bastard halibuts two to three times generally in the period that the length of the bastard halibuts is 8-10 cm, and feeding after the separation according to growth situation when the length of the bastard halibuts is 10-20 cm. Through the manner, according to the artificial culture method for the bastard halibuts disclosed by the invention, the manner of seaside captivity is adopted, and a good growing environment complemented with a scientific cultivation technique is provided for the bastard halibuts, so that the stress resistance is increased, and the survival rate is greatly improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an artificial breeding method for flounder. Background technique [0002] Commonly known as tooth slices, left mouth, partial mouth, flounder, flounder is a rare marine fish and one of the important seawater cultured fish. Its individual is huge, the meat is tender and delicious, deeply loved by consumers, the market is very broad, and the economic value is very high. The research on artificial hatching of flounder in my country began in the late 1950s, and seedling manufacturers spread all over Shandong, Hebei, Liaoning and other provinces. Since the 1990s, flounder culture has developed rapidly. In addition to cage and pond culture, Weihai, Yantai, Qingdao and other places in Shandong are vigorously developing factory culture production. However, the existing culture methods all use indoor culture, which not only requires Artificially feeding a large amount of bait requires energy ...

Problems solved by technology

Since the 1990s, flounder culture has developed rapidly. In addition to cage and pond culture, Weihai, Yantai, Qingdao and other places in Shandong are vigorously developing factory culture production. However, the existing culture methods all use indoor culture, which not only requires A large amount of bait is artificially fed, and energy consumption such as light and oxygenation is required. The cost of raising seedlings is high, and it grows under simulated natural conditions. The body is weak, the resistance to stress is poor, and the survival rate is low.
