A culture method for improving the muscle quality of large yellow croaker and a circulating flow culture pond

Abstract

The invention discloses a culture method for improving the large yellow croaker muscle quality and a circulating flow culture pond. The circulating flow culture pond comprises a rectangular cement pond body, a separation plate parallel to the long edge of the cement pond body is arranged in the middle of the cement pond body, and the two ends do not make contact with the cement pond body; a waterpush mechanism is arranged on the portion, close to the short edge of the cement pond body, on one side of the separation plate, a first blocking net is arranged in front of the water push mechanism,and a second blocking net is arranged on the other side of the separation plate. The water push mechanism, the first blocking net and the second blocking net are arranged at the same end of the cementpond body. The culture method comprises the following steps that large yellow croakers are cultured in the circulating flow culture pond; the circulating flow culture pond is arranged in an indoor factory-like environment, and a circulating water flowing environment is formed; the large yellow croakers are fed with home-made pellet feed; shading measures are adopted in an aquaculture workshop. Bymeans of the method, the meat quality of the commonly cultured large yellow croakers can be changed within two months, and the meat quality can reach the muscle quality of wild large yellow croakers.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a cultivation method for improving the muscle quality of large yellow croaker and a circulating flow cultivation pond. Background technique [0002] Known as the "National Fish", large yellow croaker is a unique endemic seawater fish in my country. It used to be the first of the "Four Sea Catch" fish in my country. It has abundant natural resources in history. There is a long culture of large yellow croaker in the coastal areas of our country. At present, large yellow croaker is the largest marine fish in my country, and its products are sold to major cities in China and countries and regions such as Japan, South Korea, Europe, and the United States. Because the large yellow croaker is kept in captivity, its body shape is relatively short and fat, and its muscles are relatively soft. It is quite different from the large yellow croaker caught in the sea in terms o...

Problems solved by technology

Secondly, the investment cost is very high. The construction of bay fork fencing requires a large investment in hardware. The investment cost of infrastructure often requires tens of millions or even hundreds of millions of dollars in investment, and many farmers cannot afford to invest.

Third, the risk of breeding is also relatively high. Since the fish are all adult fish and there are a large number of them, in case of disease, the loss will be very heavy.

The fourth is the high cost of starting the catch. Since it is aquaculture on a large water surface, it needs to be rounded up with a net when starting the catch, and the labor cost is relatively high.

Ecologically imitative fish are often sold in multiple batches, which virtually increases the initial cost of catching
