Embodiment Construction

[0015] The following specific examples further describe the present invention in detail.

[0016] Incubation pool: cement pool with an area of ​​10m 2 , the depth is 80cm, the air stones are evenly distributed according to 1.5 pieces / square meter, and the aeration volume can be adjusted from 0.2 to 1.5L / h; hatching water: the water source is natural pond water with a transparency greater than 40cm, which is filtered through a quartz sand tank and sterilized by ultraviolet rays After entering the hatching pond, the first water level is 50cm, the water temperature is 26-30°C, the dissolved oxygen is not less than 5mg / L, and the pH value is 7.5-8.5; Incubation: During the natural breeding season of the broodstock pond, artificial fish nests with fertilized eggs are collected and fertilized. After cleaning and disinfecting, hang them in the hatching ponds, the number of hanging in each pond is 5-8, and the artificial fish nests are plastic tubes with a length of 30-40cm and a diam...

Abstract

The present invention discloses a Hetang murrel fry rearing method. Said method includes the following steps: incubation pond selection, selecting water for incubation, fish roe incubation, fry rearing and breeding fish fry in later atage. Said invention also provides the concrete requirements and concrete measures of the above-mentioned every step.

Description

technical field [0001] The invention relates to a fish seedling raising method, in particular to a brown pond snakehead seedling raising method. Background technique [0002] Oxyeleotris marmoratus, also known as bamboo shoot shell fish, is a high-quality freshwater fish in the tropics and subtropics. It is native to Cambodia, Thailand, Vietnam and other countries. It is a freshwater aquaculture species with high economic benefits. Fish has great prospects for breeding and development in the south, southwest and east of China. It is an updated variety with high returns for freshwater aquaculture and greenhouse soft-shelled turtle industry. As long as the seedling cultivation in the early stage and the rearing method in the later stage are solved, it can be popularized on a large scale. Since the fish was introduced into my country in the 1980s, the artificial breeding technology has not made a breakthrough. Ecology, the survival rate of larvae is extremely low. Failure to f...
