Deepwater storm-resistant fish nest and manufacturing method thereof

Abstract

The invention discloses a deepwater storm-resistant fish nest and a manufacturing method thereof, and belongs to the technical field of fishery resource maintenance. The deepwater storm-resistant fish nest comprises an H-shaped frame, a connecting pipe, a rope, a first floating ball, a second floating ball and a fish nest body. The H-shaped frame is manufactured, the frame can be firmer, and frame distortion caused by the combined action of storm thrust and anchor stone tension is effectively avoided; a stainless steel pipe is adopted, the tensile property is high, and pollution is avoided; the two ends of the steel pipe are sealed, so that certain buoyancy is achieved; and the fish nest with wrinkles is of a fluffy structure, is suitable for fish eggs to adhere to, and is simple to manufacture, convenient to replace and suitable for large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of fishery resources conservation, and relates to a deep-water storm-resistant fish nest and a manufacturing method thereof. Background technique [0002] Artificial fish nests refer to facilities that simulate the ecological environment of fish, use alternative materials to artificially build, and set up in specific waters for fish to spawn and reproduce and juvenile (juvenile) fish to inhabit and grow. By setting up artificial fish nests to provide artificial spawning and breeding places for fish in natural waters where the spawning grounds are destroyed, multiply and improve the structure and quantity of wild fish populations, and achieve the purpose of restoring and rebuilding ecological habitats and enriching fishery resources. It makes up for the limitations of difficult management of artificial breeding and release of fish, high input costs, and risk of germplasm pollution. [0003] Because fish nest...

AI Technical Summary

Problems solved by technology

This kind of fish nest with bamboo poles or wood as a frame once played an important role in small water bodies with less wind and waves, but for large water surfaces, it is necessary to fix the fish nest at a certain position in the water area during the construction of the fish nest. The fish nest frame is fixed by dropping an anchor stone of about 150 catties on the fish nest frame; under the combined long-term action of the wind and wave thrust and the anchor stone pull, the general frame will be deformed until it is damaged; the service life of the bamboo pole or wood itself is relatively short, probably It is only about 3 years, resulting in time-consuming, labor-intensive, and material-consuming due to repeated processing; secondly, this kind of material can only be assembled on site, and cannot be industrialized; thirdly, the long bamboo poles or wood are extremely inconvenient to transport, so Can only take materials nearby
