Tower-type artificial fish reef for breeding enhanced and released fries in marine ranch and breeding method

Abstract

The invention relates to the technical field of marine fishery resource maintenance and development, in particular to a tower type artificial fish reef for breeding enhanced and released fries in a marine ranch and a breeding method. According to the tower type artificial fish reef for breeding the enhanced and released fries in the marine ranch, net racks with different mesh specifications are mainly utilized to be arranged on different tower layers of the tower type artificial fish reef, and artificial fish reef design and construction for layered and repeated utilization of bait and graded protection of fishes are realized; and according to the tower type artificial fish reef for breeding the enhanced and released fries in the marine ranch, the net racks with different mesh specifications are arranged at the windows of the different tower layers, released young fries, juvenile fishes, small fishes and small and medium-sized fishes with different specifications can be effectively protected, graded protection of the young fries is achieved, the young fries can be prevented from being caught by large and medium-sized fishes, and the survival rate of released small and medium-sized fries is increased.

Description

technical field [0001] The invention relates to the technical field of conservation and development of marine fishery resources, in particular to a tower-type artificial fish reef and a cultivation method for breeding and releasing seedlings in marine pastures. Background technique [0002] Marine ranching is a new type of marine fishery production model that is constructed in a suitable sea area with the functions of environmental protection, resource conservation and sustainable fishery output through the use of modern engineering technology and management models in natural open sea areas through proliferation and release and habitat restoration. Breeding and release is one of the key technologies in the construction of marine pastures. It is to directly release seedlings, eggs or adults of various fishery resources artificially propagated and cultivated into natural open sea areas to restore or increase the number of fishery resources in natural sea areas. A marine fisher...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the invention of the present invention is: in order to solve the problem that the survival rate of the breeding and releasing seedlings in the marine ranch is too low in the prior art, the present invention provides a tower type artificial fish reef and a cultivation method for breeding the breeding and releasing seedlings in the marine ranching. Feeding on the top of the tower can meet the baiting requirements of released fry of different specifications, protect and release young fry in different grades, and improve the conservation effect of fishery resources in marine pastures.
