Net cage for dietary domestication of siniperca scherzeri as well as use method thereof

Abstract

The invention relates to a net cage for dietary domestication of siniperca scherzeri. The net cage comprises vertical columns (1), floating rods (2) and a net body (3), and is characterized in that the net body (3) of the net cage is a container which is open for the upper surface and hollow for the interior; the outer wall and the bottom surface of the net body (3) are made of soft sheet materials forming grids; the net body (3) adopts a rectangular cage body structure; an upper top corner and a lower top corner of the four side edges of the cage body structure of the net body (3) are respectively fixed to the upper parts and the lower parts of the four vertical columns (1); the four vertical columns (1) are vertically arranged on the outer side of the four corners of the cage body structure of the net body (3) respectively; every two of the vertical columns (1) are connected by each of the floating rods (2); and the two ends of each of the floating rods (2) are respectively connected with the middle of each of the vertical columns (1). According to the net cage, wild siniperca scherzeri is successfully domesticated to eat an artificial compound feed, and the success rate of domestication reaches than 95%.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and particularly relates to a net cage for the edible domestication of Siniperca chuatsi and a method for using the same for the edible domestication of the fish. Background technique [0002] Siniperca scherzeri (Siniperca scherzeri), also known as rock mandarin, belongs to the order Perciformes. It is a valuable freshwater economic fish, widely distributed in inland waters of my country. Mandarin mandarin fish has delicious meat, few intermuscular spines, and high nutritional value. It is a valuable species for exporting foreign exchange and has broad prospects for development and breeding. Siniperca chuatsi is a typical carnivorous and ferocious fish that feeds on live fish and shrimp for life in natural waters. However, it is difficult to ensure enough live bait during the breeding process. In addition, live feed fish are often injured in the process of fishing and transportation due to patho...

AI Technical Summary

Problems solved by technology

According to reports, the common method of taming mandarin mandarin fish is to gradually add chilled dead miscellaneous fish to the fresh and live bait to reduce the content of fresh and live bait, and finally completely feed the chilled dead miscellaneous fish. Although this method can solve the problem of live bait The problem of insufficient supply, but the bait coefficient is high, the cost of breeding is high, and the spotted mandarin fish is easy to be infected with germs, etc.; on the other hand, due to the large amount of small miscellaneous fish used as bait, it also has a negative impact on the increase in the production of freshwater fisheries in my country
