Method for cultivating, domesticating and breeding glypotsternum maculatum by circulating water

Abstract

The invention discloses a method for cultivating, domesticating and breeding glypotsternum maculatum by circulating water, and belongs to the technical field of aquaculture, solving the technical problem that a large quantity of the glypotsternum maculatum die when they grow to about 3.3 cm. The method is characterized in that a plurality of culture tanks are erected in a glass fiber reinforced plastic pool, a plurality of gaps are distributed on the side wall of each culture tank, smooth stones, or coarse sand in watercourses are put in the culture tanks in an overlaying mode, water is distributed into the culture tanks through water distribution pipes, a water return pipe is arranged at the bottom of the glass fiber reinforced plastic pool and is connected with a water level control pipe, and a water outlet pipe is connected to the outer wall of the water level control pipe; a movable biological treatment tank is connected with the water outlet pipe; the movable biological treatmenttank, a connection pipe, a fixed biological treatment tank, an overflow pipe, a sand filtration tank, a purification tank and an oxygenation tank are communicated in sequence; a circulating pump, a temperature detection controller and a PH value monitoring and detecting instrument are arranged on the oxygenation tank; the circulating pump, an ultraviolet disinfection device and a water inlet manifold are connected in sequence. The method is used for cultivating and domesticating the glypotsternum maculatum.

Description

technical field [0001] The invention relates to a breeding method for cultivating and acclimating the black spotted catfish, in particular to a method for cultivating and domesticating the black spot catfish by using circulating water, and belongs to the technical field of aquaculture. Background technique [0002] Glypotsternum maculatum (Glypotsternum maculatum), belonging to the family Siluriformes and the genus Glypotsternum maculatum, is called Bagri in Tibetan. It is mainly distributed in the main stream and its tributaries of the Yarlung Zangbo River section from Bomi to Shigatse in Tibet. It is the only species distributed in the middle and upper reaches of the genus family, and its number has been decreasing in recent years. [0003] Black-spotted catfish is abundant in the middle reaches of the Yarlung Zangbo River at an altitude of 4200m in Tibet. Although the output is not large, the meat is tender, delicious, with few spines and high nutritional value. It is a r...

[0009] Example 3. The applicant is the Fisheries Science Research Institute of the Tibet Autonomous Region Academy of Agriculture and Animal Husbandry Sciences, the application number is CN201721438000.5, and the utility model patent for the invention and creation named as the fertilized egg hatching and larvae breeding device of the black-spotted catfish is disclosed as follows: During the hatching process of the fertilized eggs of P. black spot, the following problems were found: the tail of the larvae emerged from the membrane, but the head and yolk sac were still in the egg membrane and could not be removed. Finally, because the time for membrane emergence was too long, a large number of larvae died

The juvenile black-spotted catfish finally opened their mouths to eat, but when they grew to about 3.3 centimeters, they died in batches
