Problems solved by technology

However, most of the parents used in artificial breeding come from natural wild populations, which have caused certain damage to the natural wild ecological environment. Therefore, artificial indoor overwintering techniques using the internal parental resources of artificial breeding have emerged one after another.
However, during the specific implementation process, it was found that the following three factors have seriously hindered the development of this technology: First, the cost of overwintering is too high
Firstly, the wintering seawater needs to go through two levels of water lifting to reach the wintering pool (namely: the first level of water lifting at the pumping station and the second leve

Abstract

The invention discloses an indoor raising and overwintering method for shrimp and crab parents, which comprises the following steps: mixing fresh water with brine, and leading the salinity to achieve 22-28 per mill; filling air, increasing oxygen and regulating temperature, leading the water temperature of a reservoir to be higher than the overwintering water temperature by 0.5 DEG C, and reducing the temperature to 9-12 DEG C; leading the parents to enter into a room; carrying out daily management; and draining water, and recycling the overwintering water after draining for saving water resources. The method can not only achieve the purposes of reducing the overwintering cost and improving the overwintering survival rate, but also achieve the desired effects of environmental protection, energy conservation and disease prevention.

Description

technical field [0001] The invention relates to the technical field of mariculture, in particular to a breeding technology for shrimp and crab parents. Background technique [0002] my country's modern marine aquaculture industry originated in the late 1970s and early 1980s. The earliest leading species of aquaculture was Penaeus sinensis, and it flourished in the 1980s and 1990s. Initially, the supply of cultured shrimp seedlings came from nets caught in natural sea areas. After entering the 1980s, the majority of fishery scientific and technological workers successfully broke through the barriers of artificial shrimp breeding technology, and began to obtain broodstock shrimp from natural sea areas, and implemented artificial seedling breeding to meet the needs of vigorous development. The supply of shrimp fry for the seawater pond aquaculture industry has made outstanding contributions to promoting the development of my country's seawater aquaculture industry. However, sin...
