Oxygenation and sand avoidance device for breeding, migration and acclimation to reduce the mortality of erupted larvae in the Yarkand plateau

Abstract

The invention discloses a reproduction migration domestication device capable of reducing the Triplophysa yarkandensis out-of-membrane larva death rate by oxygenating and belongs to the technical field of fisheries science. The main structure of the device is a domestication cylinder (1), the domestication cylinder (1) is a container which simulates the natural growth water environment to domesticate the Triplophysa yarkandensis out-of-membrane larva and reduces the death rate of the larva, is made of glass, stainless steel, aluminum alloy, plastic, ceramic or concrete and is in a cuboid shape, the inside of the domestication cylinder (1) is hollowed and is a domestication cylinder cavity (11), upper top surfaces of the six surfaces of the domestication cylinder (1) are opened, the rest peripheral walls of the domestication cylinder (1) are domestication cylinder walls (21), and the other structural components are all arranged in the domestication cylinder cavity (11) inside the domestication cylinder (1). The reproduction migration domestication device capable of reducing the Triplophysa yarkandensis out-of-membrane larva death rate by oxygenating is simple in manufacturing, high in operability, low in cost and remarkable in effect.

Description

Technical field[0001]The invention relates to a reproductive migration and domestication device for oxygenation and sand avoidance to reduce the mortality of larval larvae of loach on the Yarkand Plateau, belonging to the technical field of aquatic products.Background technique[0002]Triplophysa (Hedinichthys) yarkandensis (Day), common name: dog head fish, belongs to the subfamily Cyprinidae, Loach subfamily, Plateau loach, is a subgenus of the genus Gus, widely distributed in the Tarim River system in southern Xinjiang of my country. As a commercial fish, the market price has reached 70 yuan / kg, which is much higher than the price of ordinary commercial fish farmed. It is a favorite delicacy for locals. The body shape of the Yarkan Plateau Loach is slightly longer, the front body is cylindrical, the pectoral fin is very wide, the abdomen is flat, the hindquarters are flat, the tail stalk is very short, and the tail stalk is less than 1 / 2 of the length of the tail stalk. The head is...

AI Technical Summary

Problems solved by technology

In the natural state, during the migration process of the Yarkand plateau loach, due to the action of sediment and other effects, many larvae will die, thus causing the number of individuals in the river to remain at a low level. Qiang plateau loach is in an embarrassing situation where there is almost no fish to catch, so how to artificially create wild scenes in the wild or in the laboratory, avoid the influence of low oxygen and sediment, artificially domesticate the larvae of Yarkand plateau loach, and improve the quality of Yeerqiang plateau loach. The number of individuals per unit of the Qiang plateau loach and the restoration of the population level of the Yarkand plateau loach in a short period of time have become a major problem that needs to be solved urgently. Therefore, a breeding and migration method that oxygenates and avoids sand to reduce the mortality rate of the larvae of the Yarkand plateau loach has been invented. A domestication device is necessary
