Embodiment Construction

[0020] A kind of cultivation method of loach seedling of the present invention, its step is as follows:

[0021] 1) Loach pond preparation: the area of ​​the inner pond for cultivating shuihua loach seedlings is: 30-50m 2 , pool depth 0.6 ~ 0.8mm 2 .

[0022] Potassium permanganate is used to disinfect the bottom and wall of the inner pond, fermented organic fertilizer or biological fertilizer is applied to the inner pond, and new filtered water is added to the inner pond for detoxification treatment and plankton cultivation , within 5 to 8 days before loach seedlings are put in, green manure 500kg / mu or manure 300kg / mu is applied, and wheatgrass is planted in the loach pond, and the grass planting area accounts for 1 / 3 of the pond area;

[0023] 2) Cultivation of loach seedlings: free-range cultivation of loach seedlings in the inner pond that has undergone water quality cultivation and detoxification treatment, and control the temperature of the water in the inner pond so ...

Abstract

The invention discloses a cultivating method of loach larvae. The cultivating method comprises the following steps: (1) preparing a loach pond: applying a fermentation organic fertilizer or biological fertilizer to an inner pond; (2) cultivating algae bloom loach larvae: feeding egg yolk, wheel animalcule and ground water earthworm, and controlling the oxygen aeration of pond water; and (3) cultivating sepia loach larvae: transferring the sepia loach larvae cultivated in the inner pond to gullies of an orchard to cultivate, feeding a powdery loach feed with the protein content of 40%-50% and water earthworms, and feeding an expanded particle feed with the particle size of 1.0mm when the loach larvae grow to be inched loach larvae. According to the cultivating method, the bottom material and the water quality of the pond are improved, the biological structure of natural forages is improved, the forages are scientifically fed, toxic and harmful substances such as ammonia nitrogen, nitrite and the like in the pond are controlled, dissolved oxygen of pond water is increased, and the natural forages of planktons are increased, so that the inched loach larvae have strong physiques and are high in survival rate, diseases of the loach larvae are reduced, and the rapid growth of the loach larvae is promoted.

Description

technical field [0001] The invention belongs to the technical field of cultivation of loach, mussel, crayfish, lobster, sponge, pearl, 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...
