Embodiment Construction

[0019] A kind of cultivation method of loach seedling of the present invention, its step is as follows:

[0020] 1) Fish pond preparation: The area of ​​the inner pond for cultivating shuihua loach seedlings is: 30-50m 2 , pool depth 0.6 ~ 0.8mm 2 .

[0021] The area of ​​the outer pond for cultivating loach seedlings is 1-2 mu, and the depth of the pond is 1.0-1.2m; for the inner pond, potassium permanganate is used to clean the bottom and walls of the inner pond, and for the outer pond, quicklime and tea are used. After the disinfection of the clear pond, fermented organic fertilizer or biological fertilizer is applied in the inner pond and the outer pond, and the inner pond and the outer pond are filled with filtered new water for detoxification treatment and plankton cultivation. Apply 500kg / mu of green manure or 300kg / mu of manure within 5 to 8 days before putting in, and plant eyebright grass in the fish pond, and the grass planting area accounts for 1 / 3 of the pond ar...

Abstract

A method for culturing loach larvae is disclosed. The method includes: 1) fishpond preparation: after the fishpond is cleaned and disinfected, a fermented organic fertilizer or a biological fertilizer is added to an inner pond and an outer pond, new water is injected into the pond, and filtering treatment and plankton culture are performed; 2) cultivation of water loach larvae: yolks, rotifers, and smashed water earthworms are fed to the water loach larvae, oxygenation of pond water is controlled, the water loach larvae are cultured for about 1 week and then grow into blank loach larvae; and (3) cultivation of the blank loach larvae, a fish mash feed with the crude protein content of 40%-50% and the water earthworms are fed to the blank loach larvae, and a puffed pellet feed with the grain size of 1.0 mm is fed to the loach larvae when the loach larvae grow into cun-size larvae. According to the method, the substrate, the water quality and a natural feed organism structure are improved, scientific feeding is performed, toxic and harmful substances such as ammonia nitrogen and nitrite in the pound are controlled, dissolved oxygen of the pound water is increased, and a plankton natural feed is increased, and in this way, the cun-size loach larvae are healthy and strong in physique, and are high in survival rate; and the diseases of the loach larvae can be reduced, and the growth of the loach larvae can be promoted.

Description

technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a method for cultivating loach seedlings. Background technique [0002] Taiwan loach is a kind of paraloach, which is mostly distributed in the middle and lower reaches of the Yangtze River in my country and the shoal rivers in the northwest of Taiwan Island. This species has fast growth, short breeding cycle, large individuals, strong disease resistance, and large profit margins. And the meat is tender, delicious, nutritious, rich in high protein, low fat, low cholesterol, VA, VB, VB2, calcium, iron, iodine and other vitamins and trace elements; Sour unsaturated fatty acids have anti-aging properties of human blood vessels, so they are beneficial to the elderly and cardiovascular patients. However, the survival rate of cultivating loach in Taiwan is very low. At present, the survival rate of most loach see...
