Loach fry cultivation method

Abstract

The present invention discloses a loach fry cultivation method. The method comprises 1) fishpond preparation: after a fishpond is disinfected, applying a fermented organic fertilizer or a bio-fertilizer to an inner pond and an outer pond, filling the inner pond and the outer pond with filtered fresh water for detoxification treatment and plankton culture; 2) breeding a fish autumn seedling; 3) cultivation for water cobitinae fries: feeding an egg yolk, rotifera and crushed tubificidae, controlling oxygenation of the pond water, wherein after about one week of cultivation, the water cobitinae fries grow to black child loach fries; and 4) cultivation for the black child loach fries: feeding the black child loach fries with a fish powder feed and limnodrilus with the crude protein content of 40-50%; when the loach fries reach an inch in length, the loach inch fries are strong in physique and high in survival rate, diseases of the loach fries are reduced, and rapid growth of the loach fries is promoted by modifying pond sediment and water quality, improving the structures of natural bait organisms, scientifically feeding bait, controlling toxic and harmful substances such as ammonia and nitrite in the pond by way of improving dissolved oxygen in the pond water and increasing plankton natural bait.

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...
