Problems solved by technology

[0003] The seedling industry of Macrobrachium rosenbergii is facing severe challenges: (1) Serious degradation of germplasm: Due to inbreeding and other reasons, the germplasm of Macrobrachium rosenbergii is seriously degraded at present, with slow growth, small individuals, many diseases, long breeding time, and failure to raise. Large and other adverse phenomena, the farmers suffered continuous losses and suffered heavy losses; (2) The production of seedlings was seriously insufficient: In the past two years, 80% of the Macrobrachium rosenbergii seedling farms in the country suffered from shrimp disease and the inability of larvae to metamorphosis seriously affected the normal production of shrimp seedlings , which has caused a situation where Macrobrachium rosenbergii seedlings are in a hurry, the price of seedlings has risen sharply, shrimp farmers are rushing to buy seedlings, and empty ponds are waiting for seedlings; Realize the transformation from quantity-based to quality-based production
(4) Backward nursery equipment: Most of the breeding sites of Macrobrachium rosenbergii still use traditional relatively simple basic equipment, and only a relatively simple rectangular pool with a height of about 90 cm is built indoors. Factors cannot be effectively controlled, nor can it be simulated in man

Embodiment Construction

[0022] A method for cultivating Macrobrachium rosenbergii seed using an aquaculture ozone culture system described in the embodiment of the present invention comprises the following steps:

[0023] (1) Build a nursery pool: the shape of the nursery pool is a square with cut corners, the side length of the square is 3.65 meters, and the cut angle is an isosceles right triangle with a right angle side length of 0.50 meters. The area of ​​the nursery pool is 12.80 square meters, and the water depth is 1.00 meters;

[0024] (2) Control the breeding density: the stocking density of Macrobrachium rosenbergii larvae is 100,000 tails per cubic meter;

[0025] (3) Temperature control: The water temperature of the seedling pool is stable at 28~32°C, the best water temperature for cultivating seedlings is 30°C, and the temperature difference should not exceed 5°C;

[0026] (4) Oxygenation measures: use a blower for oxygenation treatment;

[0027] (5) Feed management: feed Artemia at 6:0...

Abstract

The invention relates to a method for cultivating a macrobrachium rosenbergii offspring seed by using an aquatic ozone culture system. In the method, a square corner-cutting offspring seed culture pond with a proper area is built and macrobrachium rosenbergii is stocked at a proper density and technologies of reasonable temperature regulation and control, oxygenation measures, feed management and cultivation water body control and the like are matched. The method has the beneficial effects that the fine and standardized management is carried out on a traditional technology of cultivating the macrobrachium rosenbergii offspring seed; and in addition, due to use of the aquatic ozone culture system, the offspring seed culturing survival rate is improved, the physique of the offspring seed is enhanced, the offspring seed culturing period is shortened and the offspring seed culturing yield and economic benefit are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating Macrobrachium rosenbergii seedlings using an aquatic ozone culture system. Background technique [0002] Macrobrachium rosenbergii ( Macrobrachium rosenbergii ), also known as Malaysian prawns, freshwater long-arm prawns, and money shrimps, are the largest freshwater shrimps in the world. or brackish waters and breeds in tidal-affected estuaries. Macrobrachium rosenbergii is the largest individual in Macrobrachium genus. It has important economic value because of its large body, wide feeding habits, few diseases, easy survival, fast growth and good nutrition. [0003] The seedling industry of Macrobrachium rosenbergii is facing severe challenges: (1) Serious degradation of germplasm: Due to inbreeding and other reasons, the germplasm of Macrobrachium rosenbergii is seriously degraded at present, with slow growth, small individuals, many diseases, lo...
