Auxiliary fish taking device for fish breeding stable breeding bucket and application method of auxiliary fish taking device

Abstract

The invention relates to an auxiliary fish taking device for a fish breeding stable breeding bucket. The fish taking device mainly comprises a cylindrical fishing net, upper steel ropes, lower steel ropes and a rope collecting clump weight, wherein an upper opening and a lower opening are respectively formed in the upper end and the lower end of the cylindrical fishing net; the upper steel ropes are arranged at the circumferential ring edge of the upper opening; the lower steel ropes are arranged on the circumferential ring edge of the lower opening; the rope collecting clump weight is arranged on the outer side of the edge of the lower opening; the free end of the lower steel ropes penetrates out from the inner part of the rope collecting clump weight; and a plurality of net weights are arranged on the circumferential ring edge of the lower opening. The invention also provides an application method of the fish taking device. According to the auxiliary fish taking device disclosed by the invention, the work of fish taking from in the stable breeding bucket can be smoothly realized, the fish taking efficiency in the stable breeding bucket is greatly improved, and besides, the manuallabor intensity of fish taking is also reduced.

Description

technical field [0001] The invention relates to an auxiliary fish fetching device for a fish breeding tank and a method for using the same. Background technique [0002] In the current fishery field, a captive tank fish farming model has emerged. When using the captive tank fish farming model for fish farming, sewage equipment is installed at the bottom of the breeding tank to recycle the residual bait and feces produced during the breeding process, which can achieve aquaculture. Wastewater zero discharge. The diameter of the captive tanks used for existing captive fish farming is generally about 3-4 meters, and the depth is generally about 1.5 meters, so that the internal fish culture space is not small. Due to the special shape, the existing traditional fishing nets cannot be used in captive tanks. Using dip nets to directly fish in captive tanks is not only slow in work efficiency, but also labor-intensive. Contents of the invention [0003] The purpose of the present...

Problems solved by technology

The diameter of the captive tanks used for existing captive fish farming is generally about 3-4 meters, and the depth is generally about 1.5 meters, so that the internal fish culture space is not small. Due to the special shape, the existing traditional fishing nets cannot be used in captive tanks. Fishing directly in captive tanks by dipping nets is not only slow in work efficiency, but also labor-intensive.
