Squid Proliferation and Release Device

Abstract

The invention discloses a cuttlefish enhancement and releasing device. According to the device, hatched young cuttlefish can enter a natural sea area successfully; the problems can be effectively solved that harmful organisms enter an incubation net cage and fertilized eggs are damaged. The device comprises a balancing weight, the incubation net cage, a net cage connection rope and a floating anti-damage cuttlefish egg hanging device; fixed fine hole net plates are arranged on the side surfaces of the periphery and the bottom surface of the incubation net cage with the upper end opened, and first floating blocks are arranged on the outer side surfaces of the incubation net cage; the net cage connection rope is connected with the bottom surfaces of the balancing weight and the incubation net cage; the floating anti-damage cuttlefish egg hanging device comprises vertical guide rods which are arranged on the outer side surface of the incubation net cage, the floating fine hole net plateswhich ascend and descend along the vertical guide rod, second floating blocks on the upper surfaces of the floating fine hole net plates and a cuttlefish egg hanging structure on the floating fine hole net plates.

Description

technical field [0001] The invention relates to the field of releasing squid, in particular to a device for multiplying and releasing squid. Background technique [0002] Mansoni squid is widely distributed along the coast of China and was once one of the traditional "four seafood" in the East my country Sea fishing grounds. With the overfishing over the years, the number of Squid mansoni has decreased significantly. By the middle and late 1980s, the squid mansoni in the coastal fishing grounds of Zhejiang could not form a fishing season and gradually disappeared. Multiplication and release is an effective means to increase the replenishment of fishery resources. Mansoni squid grows fast and has a short reproductive cycle, so it is an ideal species for multiplication and release. [0003] At present, the following two methods are usually used for the proliferation and release of squid: one is that the squid larvae are released directly; the other is that the fertilized eggs...

AI Technical Summary

Problems solved by technology

The needleless cuttlefish fertilized egg release device of this application is also equipped with fine nets on the inner side and inner bottom of the frame, and the top surface is provided with a coarse grid with an aperture larger than the fine net. The mesh of the coarse mesh plate is relatively small Large, the hatched young squid can swim out through the mesh of the coarse-mesh mesh plate and enter the natural sea area; it also has the shortcomings of the above-mentioned hatching cages
