Large-scale efficient cultivation method for turbot

Abstract

A large-scale efficient cultivation method for turbot comprises a fry releasing and separating step; a water quality managing step: the suitable cultivation temperature is 12-21DEG C, the suitable salinity is 10-32, the dissolved oxygen needs to be above 5mg / L, the ammonia and nitrogen is smaller than or equal to 0.2mg / L and the most suitable pH value of the cultivation water body is 7.6-8.5; a bait casting managing step; a fish disease prevention and control step; and an adult fish harvesting step. Aiming at the growth and eating characteristics of the turbot, a whole group of high-quality compound feed needed in the turbot cultivation process is developed, technological innovation is carried out continuously, the whole managing process of the turbot cultivation is continuously improved, an advanced cultivation mode is summed up and is called seven-advantage turbot 17369 golden cultivation mode for short, the whole cultivation process is more scientific and reasonable, the cultivation process is more strict in monitoring and managing, and the cultivation benefits are also greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for large-scale and high-efficiency turbot cultivation. Background technique [0002] Since the introduction of turbot into my country, it has set off the fourth wave of mariculture, and it has been cultivated on a large scale in my country's coastal areas for a while, especially in Shandong and Liaoning provinces. The cultivation of turbot has become the backbone of mariculture. It has made great contributions to promoting the increase of fishermen's income and driving the development of local economy. [0003] In the process of turbot breeding, although the industrialized recirculating aquaculture model using underground deep well water has been established, a large part of turbot farming producers, based on the convenience of obtaining materials and the consideration of immediate cost savings, do not use water during the breeding process. Mainly feed c...

AI Technical Summary

Problems solved by technology

In this way, although the feed cost seems to be reduced, from the perspective of the whole breeding process, not only did not reduce the cost, but also it is easy to introduce new pathogens, which brings a lot of risks to the culture of turbot

[0004] On the other hand, the management of the entire breeding process by the breeding producers is generally extensive, and the breeding of turbot is unscientific, which not only easily causes diseases of the cultured turbot, but also easily leads to waste of feed and increase of cost

[0005] The third point is that the farmers are limited by their own breeding level, and they don’t know enough about some farming equipment, so they can’t achieve the purpose of scientific use, resulting in a waste of resources for farming equipment

[0006] Finally, the management of environmental conditions by farmers is extensive, and strict environmental management is not implemented, which reduces the efficiency of turbot farming

There is also no establishment of strict supervision conditions based on the growth characteristics of turbot, and effective management of water temperature, pH, salinity, and dissolved oxygen, resulting in low breeding efficiency and prone to problems during the breeding process
