Problems solved by technology

The amount of existing resources is getting less and less. Although the female mussels conceive hundreds of thousands of larvae during the breeding period, the survival rate of the larvae released into nature is extremely low, only a few per one hundred thousandth. Provide basic guarantee for release and scientific research

Embodiment 1

[0029] Embodiment 1, a kind of artificial breeding method of twisted clams, the steps are as follows:

[0030] This implementation case was carried out in Xiaojinshan Breeding Base of Anhui Shuiyun Mollusc Breeding Company in May 2020.

[0031] 1. Mussel screening and water domestication:

[0032] 1. Screening principles of mussels,

[0033] The twisted clam species used for artificial breeding is called parent clam. When screening, the parent clam with a large size, no damage on the surface, and a hard shell of about 3-5 years old should be selected ( figure 1 ), so that both the young and the robustness of the parent clam can be guaranteed, which is suitable for artificial breeding.

[0034] 2. Water domestication of mussels,

[0035] At the beginning of May, the cultivation pool was cleaned. The size of the cultivation pool was 3.0m×1.5m×0.5m (length×width×depth). Quicklime was sprinkled for disinfection. After rinsing, it was exposed to the sun for three days, and then ...

Abstract

The invention discloses an artificial breeding method of arconaia lanceolata. The artificial breeding method comprises the following steps of parent arconaia lanceolata screening and running water domestication, host fish selection and intensive culture, glochidium development condition inspection, glochidium collection, glochidium parasitism, host fish feeding, glochidium separation, young arconaia lanceolata cultivation management, net cage hanging cultivation and later-period maintenance management. The method is scientific, easy to manage and protect, high in reproductive rate, low in cost, controllable in process, low in maintenance cost and convenient to popularize and produce on a large scale, solves the problem that the reproductive rate of the arconaia lanceolata in the nature is extremely low, and has great practical significance in scientific research of the arconaia lanceolata and proliferation and release of arconaia lanceolata germplasm resources.

Description

technical field [0001] The invention relates to an artificial breeding method of freshwater shellfish, in particular to an artificial breeding method of twisted clams. Background technique [0002] Twisted clams are commonly known as Jiaozi, banana mussels, and twisted clams. This species is endemic to our country, with hard shells, which are raw materials for making buttons and handicrafts; the meat can be eaten by people and the natural bait of poultry and fish. Gyrus clams are dioecious, and the external gills of female clams are brood sacs, which reproduce once a year, and the peak of larvae discharge is concentrated in June to August every year. The mature gonads of the parents are all pink, while the gonads of the female clams with larvae turn white or light yellow. This species is endemic to our country. Gyrus clams mostly inhabit lakes with muddy or sandy bottoms, and tributaries of the Yangtze River. They like running water and mainly filter-feed on microalgae an...
