Embodiment 1

[0014] A flounder breeding base in Haitou Town, Ganyu, Lianyungang has industrially cultured more than 40,000 star flounder, of which 10,000 are mixed with turbot and star flounder. The water quality conditions and management are as follows:

[0015] The water temperature for breeding is 13-23°C, the salinity of the breeding water is 14‰-17‰, pH 7.5-8.5, continuous aeration, dissolved oxygen at 6-8mg / L, ammonia nitrogen ≤0.01mg / L, daily water change 4-5 water, feed twice a day, the feed is made of fishmeal + feed fish through granulation and air-drying, the seedling length is about 7cm when stocking, and the size is selected every 2 months in the first 6 months of the breeding period Divide the pools, select the size of the pools every 3 months in the next 9 months, and replace and clean the pools every month. The number of stocking turbot accounts for 4%-5% of the cultured population of star flounder, and the stocking densities of star flounder and turbot are shown in Table 1...

Embodiment 2

[0020] A flounder flounder breeding base in Rizhao City industrially breeds more than 50,000 star flounder, of which 10,000 are mixed with turbot and flounder. The water quality conditions and management are as follows:

[0021] The water temperature for breeding is 13-23°C, the salinity of the breeding water is 23‰-26‰, pH 7.5-8.5, continuous aeration, dissolved oxygen is maintained at 6-8mg / L, ammonia nitrogen ≤0.01mg / L, and water is changed 4 times a day. -5 water, fed twice a day. The feed is a certain brand of turbot feed. The seedlings are about 5-7cm long when they are stocked. The first 6 months of the breeding period are selected every 2 months. In the next 9 months, the size of the pools will be selected every 3 months, and the pools will be replaced and cleaned every month. The number of stocking turbot accounts for 4%-5% of the breeding quantity of star flounder. The stocking densities of star flounder and turbot are shown in Table 2.

Abstract

The invention relates to a mixed breeding method of spotted halibut and turbot. The turbot with the breeding number accounting for 4%-5% of that of the spotted halibut are stocked. The mixed breeding method is convenient to implement, the observation is convenient, features of different biological characteristic aspects under the same breeding conditions are combined, and therefore the pathogenic bacterium conditions in breeding water can be more conveniently observed and judged, and the breeding survival rate of the spotted halibut is increased.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for polyculture of flounder and turbot. Background technique [0002] Star flounder is a cold-temperate demersal fish with an oval body and scales on the body surface. It belongs to the family Plaiceidae, subfamily Plaiceidae, and the genus Star Plaice. Dark brown, often mixed with light-colored areas of different sizes, the living temperature is 4°C-25°C, and the suitable water temperature is 15°C-23°C. There are various breeding modes for the star flounder, mainly factory farming. If the factory farming process is not well managed, diseases such as fin ray rot and body surface rot are prone to occur. However, because the body color of the star flounder is gray-green or dark brown, it is difficult for farmers to observe through characterization without detection equipment. It is found that the star flounder has been diseased, so an easy-to-observe indicator orga...
