Embodiment approach

[0061] In detail, as an embodiment of the fish fry cultivation method of the tower-type artificial fish reef for breeding and releasing seedlings in marine pastures of the present invention, the following steps are included:

[0062] First of all, select a shallow sea area with a flat seabed terrain of less than 10m, concrete the first reef layer 1 and the second reef layer of the tower artificial reef, form the first component and hang it on the seabed smoothly, and then install the third reef layer of the tower artificial reef The fish reef layer 3 and the fourth fish reef layer 4 are poured with concrete to form the second member suspended and installed on the first member, and then the fifth fish reef layer 5 of the tower artificial fish reef and the fish reef layer placed on the top floor The top 6 is poured with concrete to form the third member suspended and installed on the second member.

[0063] As a further example of this embodiment, when the fry are being cultivat...

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...
