A kind of large-scale breeding method of clam-shaped Anodon

Abstract

The invention discloses a method for large-scale breeding of cockle-shaped clams, which comprises the following steps: (1) preparation of breeding pools, (2) collection of parents, (3) domestication and fertilization of parent clams, (4) fertilization of female clams Screening, (5) collection of juvenile mussels, (6) transfer of parent mussels, (7) cultivation of mussel seedlings, (8) prevention and control of predators, (9) hanging culture in net cages: (10) later maintenance and management. The invention can breed cockle-shaped clams in large quantities, with high breeding rate, controllable breeding process, high yield, easy management and low cost. A large number of young clams can be produced in the next year, and the young clams can be used for multiplication and release, scientific Research, water purification, and at the same time, under the circumstances of rising meat prices, closure of small and medium-sized farmers, and ban on fishing in the Yangtze River, it is a rare alternative meat with better taste and rich nutrition, which has huge market economic value and ecological value.

Description

technical field [0001] The present invention relates to a large-scale breeding method of the algae, which can be used to rapidly expand the population, obtain an objective quantity in the second year, and can be used for both proliferation and release and food processing. The economic value is relatively high, and it belongs to the field of the breeding method of freshwater shellfish with high economic value, high added value and can be used as meat substitute. Background technique [0002] Clam-shaped toothless mussel is a special member of freshwater shellfish. It is currently known among freshwater shellfish bivalves in China. It is the only mussel that does not require parasitic fish or metamorphosis. Fast, the mussels can reach sexual maturity when they are one year old, and the hook-mediated larvae directly develop and mature in the outer gill flaps of the female mussels. No parasitic fish is required for this process. Toothless mussels have thin shells and lots of f...

AI Technical Summary

Problems solved by technology

Cockle-shaped clam has thin shell and more meat, fast growth, low breeding cost, no pollution in the breeding process, and can also purify eutrophic water; the taste of cockle is more delicate than other freshwater shellfish, and it is rich in protein , minerals, trace elements, etc., can be directly cooked or processed as canned products, dry goods, etc., because it reproduces quickly, has low breeding costs, and is rich in nutrition, so it can be used as an alternative meat, which will greatly alleviate poverty-stricken areas and countries. Due to the economic situation of shortage and soaring meat price, and there is no large-scale breeding and deep processing industry of cockle-shaped mussels in China, so this industry has great economic and social value
