Freshwater shrimp multiplication reef capable of feeding fodder

Abstract

The invention discloses a freshwater shrimp multiplication reef capable of feeding fodder. The freshwater shrimp multiplication reef capable of feeding fodder is characterized in that the multiplication reef is of a cylindrical structure with the diameter of 50-100 cm and the length of 2-5 m, and is made of PVC pipes, bamboo rods and polyethylene meshes. When the multiplication reef is used, the multiplication reef is arranged at the bottom of water with the water depth of 1-3 m; a feeding hole needs to float on the water level to bring convenience for feeding the fodder; as the two ends of the multiplication reef have no mesh, the freshwater shrimps enter into the multiplication reef from the two ends thereof for inhabiting, foraging and breeding, so that the inhabiting and breeding place of the freshwater shrimps is enlarged; the fodder is put inside the multiplication reef from the feeding hole, so that the freshwater shrimps can obtain the fodder without going out of the multiplication reef, the growth of the freshwater shrimps is speeded up, and the yield per unit area of the freshwater shrimps in the multiplication reef setting region is improved. The materials used in the invention are easy to obtain, the manufacturing method is simple and convenient, the use effect is good, and the freshwater shrimp multiplication reef is high-quality multiplication reef for multiplication of the freshwater shrimps in lakes.

Description

technical field [0001] The invention relates to the field of fishery, in particular to a freshwater shrimp multiplication reef which can be fed with feed. Background technique [0002] Green shrimp is one of the freshwater shrimps with high economic value. It grows fast, has a large individual, reproduces fast, has strong vitality and is widely distributed. [0003] Freshwater prawn meat is tender and delicious, rich in nutrition, tender and delicious, and is a famous and precious aquatic product that is loved by people. [0004] The distribution of freshwater shrimp in our country is very wide, and it is widely distributed in freshwater lakes, rivers, ponds and swamps. [0005] Freshwater shrimps have poor swimming ability and can only swim for short distances. They often climb and crawl in the grass at the bottom of the water; when they are frightened or attacked by enemies, they can use their abdomen to contract sharply, their tail fans to push water back, and then their...

Problems solved by technology

[0008] Due to changes in the water environment, there are fewer and fewer spaces in the water body suitable for the breeding and habitat of freshwater shrimp, and the food source for freshwater shrimp is also insufficient. The natural production of freshwater shrimp in the water area is decreasing year by year, which limits the market supply of freshwater shrimp
