Embodiment 1

[0039] A method for artificial cultivation of juveniles of P. nigra, comprising the following steps:

[0040] 1. Disinfection of breeding tools and parallel tanks

[0041] (1) Types of tools for daily use: small square mesh with dense eyes, brushes, scouring pads;

[0042] (2) Disinfection method of breeding tools: Disinfect tools once every two weeks, first soak and disinfect with povidone-iodine solution for 2 hours, and then wash with clean water for 7 to 8 times, and completely remove drug residues before use; among them, povidone The amount of iodine solution used is per 1m 3 375mg povidone-iodine solution in water;

[0043] (3) Disinfection method of parallel tank: first soak and disinfect with povidone-iodine solution for 24 hours, after disinfection, wash with clean water for 5 times, then soak with clean water for 24 hours, and then clean for 5 times to ensure that there is no drug residue before use; wherein The dosage of povidone-iodine solution is per 1m 3 The wa...

Abstract

The invention provides a method for artificial cultivation of juveniles of P. nigra, including: disinfection of breeding tools and parallel tanks; daily management and cleaning; selection of bait; and feeding methods of chironomid larvae. The method for cultivating the juveniles of the black spotted platypus has the advantages of simple operation, low cost, good quality of domesticated seedlings, etc., breaks through the bottleneck of cultivating the juveniles of the black spotted platypus, and the survival rate of the seedlings cultivated to 19 months of age reaches 80% It can effectively solve the problem of high mortality of larvae caused by the discomfort of bait, feeding method and environment during the domestication and breeding of the fry, and it also provides a reference for the cultivation of fry and seed of other species.

Description

technical field [0001] The invention relates to an artificial cultivation method for juveniles of P. nigra, and belongs to the technical field of aquatic product cultivation. Background technique [0002] Glyptosternum maculatum (Glyptosternum maculatum) belongs to the order Syriformes, Glyptidae, and is a unique fish in the middle and upper reaches of the Yarlung Zangbo River in Tibet (2800-4200m above sea level). It has a unique biological evolution mechanism adapted to the plateau waters. The flesh is tender, delicious, with few intermuscular thorns, and has certain medicinal value. It is an important raw material for Tibetan medicine and is deeply loved and respected by people in Tibetan areas. However, in recent years, due to the influence of overfishing, water conservancy projects, environmental pollution and habitat changes, the population resources of the black-spotted hornet have continued to decrease, only scattered in the middle and lower reaches, and are facing t...
