Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] A method for cultivating grouper fry, characterized in that: comprising the steps of:

[0024] Step 1. Preparation of the breeding pond. A water wheel is set in the breeding pond to ensure sufficient convection of the upper and lower water bodies, and the water body is kept in a good state, which is beneficial to the survival and growth of grouper fry.

[0025] Step 2. Prepare water for cultivation, use sand-filtered seawater as water for cultivation, disinfect the water with ultraviolet light, put the water for cultivation into the cultivation pond of step 1, and dissolve oxygen in the cultivation water, the dissolved oxygen is 7-10mg / L, Sufficient ...

Abstract

The invention discloses a culture method for grouper fries. The culture method is characterized by comprising the following steps: 1, preparing for a culture pond, and arranging a water wagon in the culture pond; 2, preparing for culture water, placing the culture water into the culture pond in the step 1, and dissolving oxygen in the culture water; 3, hatching spawns, placing the spawns into a vessel for hatching, and placing the vessel into the culture pond, wherein the water in the vessel is culture water; 4, culturing fish fries, and placing the hatched fish fries into the culture pond forculture; and 5, separating the fish fries by sieving, catching and sieving the fish fries every 30 days, and culturing the fish fries in different ponds according to a specification that the sizes are unified. The culture method disclosed by the invention achieves the aims of increasing the survival rate of grouper fries and reducing the mutual killing and devouring phenomena by providing good water quality, regulating the water temperature, reasonably arranging the stocking density, fortifying the nutrition and increasing the vitality.

Description

technical field [0001] The invention belongs to the technical field of fish culture, and in particular relates to a grouper fry culture method. Background technique [0002] Grouper is a warm-water, wide-salinity, large and medium-sized carnivorous fish. It is a rare species that is cultivated in fish ponds or cages near the sea in our southern region. Grouper is a high-grade seafood with high protein and low fat, and it is also the first-class delicacy for people's festive banquets. Due to the fact that there are not many domestic breeding areas, the breeding area is small, and the traditional farming methods are outdated, the survival rate of grouper fry farming is not high. The supply of grouper fish currently cultured is in short supply and cannot meet the needs of the market. Contents of the invention [0003] The object of the invention is to solve the problem of low survival rate of grouper fry in the current culture process of grouper fry, and provide a method for...
