Method for ecologically breeding pelteobagrus fulvidraco

Abstract

The invention discloses a method for ecologically breeding pelteobagrus fulvidraco. The method comprises the following steps: constructing an ecological floating bed, culturing in a planting barrel, stocking pelteobagrus fulvidraco fingerling, arranging the ecological floating bed, dynamically adjusting the floating bed, performing breeding management and the like. According to the method, arrangement and adjustment of the ecological floating bed are beneficial to maintaining the water temperature of a pond in a reasonable range and keeping the pond water to be clear, and an appropriate breeding water environment is produced to bred pelteobagrus fulvidraco. The pelteobagrus fulvidraco ingesting below the planted herba houttuyniae and the like is beneficial to improving the its immunity, and usage of medicines can be reduced. Besides fish catch, water spinach, herba houttuyniae and other economic crops can be harvested.

Description

technical field [0001] The invention belongs to the fish breeding technology, and in particular relates to an ecological breeding method of yellow catfish capable of arranging floating islands in a breeding pond and realizing ecological temperature control of the yellow catfish by changing the arrangement of the floating islands between day and night. Background technique [0002] At present, the pond culture of the yellow catfish is the same as that of other fishes, using methods such as water injection in the pond, stocking fish species and feeding feed. Yellow catfish is a bottom fish. It likes to live in groups, likes shade and hates light, likes to be quiet and less active, and is nocturnal. The optimum temperature for growth is below 29°C. It usually looks for and ingests bait at night, through 4 pairs of beards and sides of the body. Receptors such as the lateral line of the body can sense the smell and direction of the bait and determine the position of the bait. In...

AI Technical Summary

Problems solved by technology

Especially in the high temperature season, the water temperature of the small water body in the pond is easy to rise. When the water temperature reaches above 29°C, the yellow catfish grows slowly, and some physiological and biochemical indicators that reflect health in the body, such as cortisol, malondialdehyde and lipoprotein, are abnormal. The nutrient metabolism and absorption of the yellow catfish cultured under this condition also have obstacles, such as fatty liver and muscle fat content are too high, the taste and taste are obviously worse than those in natural waters, and the survival rate is reduced, etc.
