Facility and method for early breeding of hyriopsis cumingii seeds

Abstract

The invention provides a facility and a method for early breeding of hyriopsis cumingii seeds. The facility comprises an egg breeding shed, a bait shed and a seed breeding shed. The egg breeding shed is provided with an egg breeding pool shed body and an egg breeding pool with an oxygenation pipeline at the bottom, breeding net boxes are arranged in the egg breeding pool; a bait pool shed body and a bait pool is arranged in the bait shed, filter screens are arranged in the bait pool; the seed breeding shed comprises a seed breeding pool shed body and a seed breeding pool, seed breeding districts are arranged in the seed breeding pool, a bait releasing pipeline is arranged above the connection position of two adjacent rows of the seed breeding districts, water drainage trench grooves are formed below the connection position of two adjacent rows of the seed breeding districts and on the periphery of the seed breeding pool, and an impounding reservoir is also arranged in the seed breeding pool; the bait pool is communicated with the seed breeding pool through a guiding pipe and a water discharging tube. The facility and the method for the early breeding of the hyriopsis cumingii seeds have the advantages that an oxygenation facility is arranged at the bottom of the egg breeding pool, oxygen can be tenderly provided for mother mussels, a circulation is formed between the bait shed and the seed breeding shed, recycle of baits can be achieved, and heat loss can be reduced; in addition, the structures of the egg breeding shed, the bait shed and the seed breeding shed are simple, assembly and disassembly are convenient, and a guarantee is provided for stable yield and high yield of the hyriopsis cumingii, and for low-cost seed early breeding.

Description

technical field [0001] The invention relates to the early multiplication of the seedlings of the triangular mussel, in particular to a system and an early multiplication method for the early multiplication of the triangular mussel seed. Background technique [0002] Triangle clams ( Hyriopsis cumingii ), commonly known as river mussels, pearl mussels, and triangle mussels, is a freshwater bivalve mollusc, belonging to the phylum Molluscs, Phallobranchia, Euphyllobranchia, Musselidae, and Sail Mussels. It is an endemic species in my country, mainly distributed Among the large and medium-sized water bodies with micro-currents such as lakes and tributaries in the Yangtze River Basin and Huaihe River Basin, the five major freshwater lakes, Poyang Lake, Dongting Lake, Taihu Lake, Chaohu Lake and Hongze Lake, are particularly rich in resources. The pearls formed by the triangular sail mussel have the advantages of smooth and delicate pearl quality, bright color and high rate of ro...

AI Technical Summary

Problems solved by technology

However, the triangle sail mussels in natural waters or culture ponds generally start to breed in early and mid-April, and the peak breeding period is from May to June. Most of the small mussels cannot meet the cutting specifications, and can only wait for spring or even autumn cuttings in the next year, which greatly delays the production of pearls, shortens the cycle of pearl cultivation, and increases the cost and risk of breeding

Some farmers also try to breed in advance by building greenhouses, that is, early breeding, but due to the unsatisfactory design of the greenhouses in each link, the breeding fails or the amount of seedlings raised cannot meet the production requirements, or the early breeding is given up because the construction cost is too high plan of

[0003] Therefore, there is an urgent need for a facility and method suitable for stable, high-yield, and low-cost seedlings of the three-sided sailfish, but there is no such facility and method at present. see the report
