Problems solved by technology

Turbot is gradually developed into an artificial breeding target because of its delicious meat and fast growth rate. However, traditional turbot farming in seawater ponds is fed with bait twice a day until full. And the disadvantages such as low utilization rate of bait

Embodiment

[0007] Using a circulating water system, a total of 9 cement pools are used, each with an area of ​​5 square meters, the water temperature is 12.5±1°C, continuous aeration, and running water cultivation. The control group S0 (normally fed every day), S1F6 (starved for 1 day, resumed feeding for 6 days), S2F5 (starved for 2 days, resumed feeding for 5 days), the breeding time was 42 days, during which they were fed twice a day, until satiated. A turbot with an average weight of 175.23±7.54g and a total length of 20.66±1.14cm was selected. Each test group is represented by S0, S1F6 and S2F5 respectively.

[0008] The result shows that, with the turbot cultured by the method of the embodiment of the present invention, the average body weight is greater than that of the control group, the food intake is less than that of the control group, and the food conversion rate of the treatment group is obviously higher than that of the control group. The specific values ​​are shown in Tab...

Abstract

The invention discloses an industrial culture method for a turbot, which is characterized by adopting a way of stopping feeding for one day and continuously feeding for six days or continuously stopping feeding for two days and continuously feeding for five days as a cycle to repeatedly circulate in the process of carrying out indoor cement pool running water culture on the turbot, the turbot is fed twice every day till satiation in the feeding period, and the labour force can be saved, thereby reducing the investment of manpower cost; the turbot is recovered to be fed after hunger, and the food conversion ratio is high; compared with a normally feeding fish pond, the invention can reduce bait investment, and the growing speed is higher than an individual which is continuously fed every day.

Description

Technical field: [0001] The invention relates to a turbot artificial breeding method, in particular to a turbot industrialized breeding method which can not only promote the rapid growth of the turbot, reduce the amount of bait fed, but also save labor and reduce the breeding cost. Background technique: [0002] Turbot is a bottom fish resistant to low temperature. It likes a quiet and dark living environment. It seldom swims and has a docile personality. The optimum temperature range for this fish is 2-28°C, the highest lethal temperature is 28-30°C, the lowest lethal temperature is 1-2°C, and the growthable temperature is 7-22°C. The suitable salinity is 12-40, and the optimum pH value is 7.8-8.6. Dissolved oxygen in water should not be lower than 4mg / L. Turbot likes to live in clusters and feeds in clusters, and is often squeezed together in multiple layers. Except for the head, the body parts can overlap, which has no adverse effects on life and growth. Turbot is grad...
