Method for raising crabs by rice grass

Abstract

The invention provides a method for raising crabs by rice grass. The method includes the steps of 1), site selection, namely selecting a beach with rice grass growing nearby as a breeding site of green crabs, wherein the breeding site is sufficient in seawater quantity in the area with sufficient light so as to ensure appropriate water temperature; 2), crab house building, namely building a crab house on land at 300-400m from the beach in the step 1), wherein meshes are arranged in the periphery of the crab house so as to ensure that the green crabs does not escape from the crab house; a floating buoy is arranged outside the crab house, a ventilation outlet is arranged in the outer side of the crab house, and ventilation can be achieved; 3), arrangement of culture equipment, namely pumpingseawater to the crab house in the step 2), setting water treatment equipment and a seawater boiler, improving the quality of seawater by the aid of the water treatment equipment and improving the salinity of seawater by using the seawater boiler. The costal natural resources are fully used, feed cost of the green crabs is reduced by the aid of the characteristics of the rice grass, and the benefit in crab raising is increased.

Description

technical field

[0001] The invention relates to a cultivation method, in particular to a method for cultivating crabs with Spartina. Background technique

[0002] Blue crabs are crabs that live along the coast of warm sea areas and are widely distributed in the Indo-West Pacific region. It mostly inhabits swamps with low salinity such as estuaries, inner bays, and mangroves. In addition to overwintering and laying eggs in the deep sea area, it basically inhabits the intertidal zone of estuaries and inner bays. Where the tidal water is smooth and the tidal range is large along the coast, mud flats, mud beaches, etc., especially in mangrove areas, are inhabited by blue crabs. Because of their large size, fast growth, delicious meat, and rich nutrition, they have become popular in modern times. And it is regarded as precious seafood in modern times, and it is also an important marine economic species for artificial cultivation in coastal areas. However, in the process of c...

[0017] Spartina culture crab method of the present invention comprises the steps:

[0018] Step 1, site selection: choose a nearby beach with Spartina as the site for blue crab breeding. The breeding site should have sufficient sea water and be in a zone with sufficient sunlight to ensure that the water temperature is appropriate;

[0019] Step 2, build a crab house: Build a crab house on land 300-400m away from the beach mentioned in step 1. There are meshes around the crab house to ensure that blue crabs do not escape from the crab house. There are buoys with floating function, and there are vents on the outside of the crab house, which can be ventilated;

[0020] Step 3: Set up breeding equipment: Use water pumps to draw seawater to the crab house in Step 2, and set up water treatment equipment and seawater boilers, use water treatment equipment to improve the quality of seawater, and use seawater boilers to improve the salinity of seawater, so as to provide blue crabs A g...
