Problems solved by technology

Sandy bottom sea ponds are the best for artificial cultivation, and a large number of low-quality shrimp ponds are used for artificial cultivation. Among them, artificial breeding and cultivation conditions in western Guangdong, Beibu Gulf and Hainan are the most suitable, and the effect is the best. However, at present, artificial breeding There are not many Portunus pelagics, and there are quite few technical research materials on the breeding and breeding of Portunus pelagics

Embodiment Construction

[0028] Below in conjunction with specific embodiment the present invention is described in further detail:

[0029] 1) Selection of parent crabs: Select parent crabs with a weight of 80-150g, a nail length of more than 7cm, and complete appendages;

[0030] 2) Preparation of holding pool

[0031] 2.1 Use 20ppm KMnO after cleaning 4 Disinfection, every 3 to 5 days, use formalin, potassium permanganate or nystatin to bathe the parent crabs;

[0032] 2.2 Pave the fine sand after cleaning and disinfecting 3 to 5 cm in the holding pond, accounting for 50 to 60% of the area at the bottom of the pond. There is no need to spread sand near the drain, and it is used as a feeding ground. The holding pond is placed every 4 to 5 cm. 5 days, thoroughly wash and disinfect the fine sand once to prevent the sand layer from turning black, or pour the pool once;

[0033] 2.3 Use tiles and bricks to build a nest for the crabs to hide and inhabit;

[0034] 2.4 The surface of the temporary pool...

Abstract

The invention relates to a juvenile crab cultivating method for high-sea swimming crabs. The juvenile crab cultivating method comprises the steps of selecting parent crabs, preparing a storage pond, managing non-egg-carrying crabs, managing egg-carrying crabs and cultivating juvenile crabs. According to the juvenile crab cultivating method for the high-sea swimming crabs, the manual juvenile crab cultivating technology study for the high-sea swimming crabs is carried out for increasing an excellent new cultivation product in Guangxi, and the method plays an important role in promoting the breed structure adjustment of sea farming industries and developing the ocean economy.

Description

technical field [0001] The invention relates to the technical field of swimming crabs, in particular to a seedling raising method of swimming crabs from the open sea. Background technique [0002] Swimming crab is a seafood product that people like to eat. It is delicious in meat and rich in nutrition, so it is favored by consumers. There are four major economic crabs in my country, namely Scylla serrata, Eriocheir sinensis, Portunus trituberculatus and Portunus pelagics. Portunus trituberculatus are mostly produced in the Yellow Sea, Bohai Sea, and East my country Sea of ​​China, while swimming crabs from the open sea are mostly produced in the South my country Sea and East China Sea. [0003] Portunus (flower crab) from the open sea, although the sea-catching output in western Guangdong, Guangxi, and Hainan is quite large, its resources are decreasing day by day. Portunus pelagics are large in size, strong in adaptability, fast in growth, less in disease, and high in eco...
