Embodiment Construction

[0020] Build a 1 hectare breeding pond to ensure its water demand and the water source is pollution-free. Check that the ponds and dams are firm and have no loopholes; spray 4500kg of quicklime per hectare for disinfection, and then release 450kg of peanut bran, 22.5kg of amino acid fertilizer and water, and 3750ml of Yuzhuangbao. Aquatic plants such as water lilies and water peanuts are planted in a circle to occupy 1 / 4 of the area of ​​the pool; keep the water depth above 1m. The water inlet of the breeding pond is arranged on a diagonal line, the water inlet is above the water surface of the pond, the outlet is buried in the lowest part of the pond, and the screen is filtered, focusing on preventing snakes, frogs, rats and other animals from harming; carry out daily inspections on time. Choose over-winter fish species over 10 cm in size, with uniform specifications, correct body shape, strong physique, no injuries, and complete fins; if the size difference is too large, cho...

Abstract

The invention relates to a high-yield manual aquaculture technique of clarias fuscus, which comprises the following steps of cleaning a pond, performing quicklime disinfection, removing weeds and pests, culturing water quality, planting a plurality of aquatic plants, putting wintering fish seeds which are healthy and strong in body and uniform in specification in mid-April, selecting corresponding feed, scattering the feed twice per day, mixing little filtering-feeding and omnivorous fish in the fish pond to stabilize the water quality, and catching and coming into a market after 6 months. The technique can effectively improve the yield and the efficiency of the clarias fuscus, thereby promoting the development of clarias fuscus aquaculture.

Description

technical field [0001] The invention relates to a high-yield bearded catfish artificial breeding technology, in particular to large-scale and rapid breeding of a large number of bearded catfish to improve economic benefits. Background technique [0002] Beard catfish is a small warm-water fish that reproduces quickly. Its meat is tender and delicious. It has a certain nourishing effect and is widely welcomed by consumers. It is a famous freshwater cultured fish. Wild beard catfish can no longer meet the needs of the market, so it is hoped that through large-scale farming, the structure of the fishery industry can be adjusted to help farmers get rich. However, the artificial breeding technology has not been deeply studied and widely promoted. Most of the breeding methods adopt extensive farming. How to adjust the artificial breeding technology of bearded catfish to achieve the purpose of high yield and improve economic benefits has become the main direction of research. Con...
