Abstract

The invention relates to an adjustable fish screen. The adjustable fish screen is characterized by comprising a frame and rotary pieces; the frame is rectangular, two opposite side frames of the frame are respectively provided with a plurality of small holes which are symmetrical in position; each rotary piece is rectangular, the middle portions of the two ends of each rotary piece are provided with screws, the rotary pieces are arranged in the frame in parallel and side by side, the screws at the two ends of each rotary piece are arranged in the corresponding small holes of the two side frames of the frame in a penetrating mode, and each screw is provided with a locking nut in a matched mode. The adjustable fish screen is simple in structure, simple and easy to operate, low in cost, and capable of effectively separating large fishes and small fishes in a fish catching process, avoids resource waste caused by manufacturing of fish screens of different standards, lowers labor consumption in a process that the fish screen is disassembled and bundled in a net cage, and is an innovation of the fish screen manufacturing technique.

Description

technical field [0001] The invention relates to an adjustable fish sieve and a cage using the fish sieve, belonging to the technical field of aquaculture. Background technique [0002] Since the reform and opening up, my country has carried out the fishery development policy of "focusing on breeding", which has enabled the rapid development of aquaculture. According to the "2012 China Fishery Statistical Yearbook", my country's aquaculture output reached 40.2326 million tons, accounting for 71.8% of the total aquatic product output (56.0321 million tons). The rapid development of the aquaculture industry is inseparable from the innovation of farming methods and the advancement of fishery technology. Among them, the method of round-catching and multi-species polyculture has played an important role in high-yield and efficient pond farming. Wheel catching and wheel placement means that in close-cultured fish ponds, according to the growth of fish, after a certain period of ti...
