Abstract

The invention relates to the technical field of the fish cultivation and in particular to a weever cultivating technology. The weever cultivating technology comprises the following steps: A, pre-processing a cultivating pond, wherein the cultivating pond comprises a cultivating area and an arc moving area, the moving area is installed in the natural pond and is isolated from the natural pond by anisolation board, two ends of the moving area are communicated with the cultivating area, an arc isolation strip is installed in the moving area, and the moving area is divided to a plurality of channels by the isolation strip; the communicated place of the moving area and the cultivating area is provided with a baffle, the baffle is connected with a driving mechanism, the baffle is slidably connected with the channels, one end of the baffle is hinged to the middle of the inner wall of the cultivating area, and the lower part of the baffle is rotatably connected with a driving blade; B, desalting fry; C, daily feeding; and D, fry movement: opening the baffle at fixed period, driving the fry to the moving area for moving and feeding, and driving the fry back to the cultivating area. The weever cultivating technology is capable of solving the problem of liver fat deposition of the weever.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a perch farming technology. Background technique [0002] The current aquaculture is limited by aquaculture resources such as water environment and land, and high-density aquaculture has become a trend. However, the increased density of intensive farming restricts the swimming of fish. At the same time, artificial feed with unbalanced nutrition completely replaces natural bait. It is often difficult to meet the needs of fast and healthy growth of fish, resulting in nutritional and metabolic disorders of farmed fish. [0003] Among them, hepatic fat metabolism disorders, deposition, infiltration, and increased fat content lead to fatty liver. Fatty liver is one of the common nutritional diseases in farmed fish. Most farmed fish, such as bass, tend to suffer from loss of appetite, poor swimming, slow growth and reduced disease resistance after ingesting high-fat, high-protei...
