Heliocidaris erythrogramma enhancement and releasing research device

Abstract

The invention relates to a heliocidaris erythrogramma enhancement and releasing research device which comprises a plastic basket with an opening in the upper end. An opening sealing piece is arranged at the upper end of the plastic basket, a plurality of drain holes are formed in the wall of the plastic basket, an opening binding mesh bag is fixedly laid on the inner wall of the plastic basket, a perching plate is arranged at the bottom of the opening binding mesh bag, and a wave perching face is formed on the surface of the perching plate. The opening binding mesh bag laid in the plastic basket provides living space for heliocidaris erythrogramma and can prevent the heliocidaris erythrogramma from escaping, the drain holes in the plastic basket facilitate water exchange and enable bait to enter the bag conveniently, the wave perching face is arranged on the perching plate, the attachment area of the heliocidaris erythrogramma is greatly increased, and the epiphytism of the heliocidaris erythrogramma is facilitated. When the survival rate and the growing and breeding conditions of the heliocidaris erythrogramma need to be observed and studied after the enhancement and releasing of the heliocidaris erythrogramma, observation can be directly carried out outside the plastic basket or the opening binding mesh bag can be taken out for research and analysis, and using is easy and convenient. The heliocidaris erythrogramma enhancement and releasing research device can be applied to heliocidaris erythrogramma enhancement and releasing effect monitor study.

Description

technical field [0001] The invention relates to the field of aquatic breeding, in particular to a purple sea urchin breeding and releasing research device. Background technique [0002] Purple sea urchin is an important fishing species in the southeast coast of my country. It has high nutritional value and medicinal value. Due to years of over-exploitation and environmental changes, wild purple sea urchin resources have declined seriously, and it is urgent to restore and maintain it by means of proliferation and release. [0003] Breeding and release is the activity of artificially releasing aquatic organism seedlings or broodstock into oceans, rivers, lakes and other public waters. In natural waters, the activities of purple sea urchins after proliferation and release are fully free, which also faces the problem that it is difficult to observe and recapture the purple sea urchins after proliferation and release, and it is impossible to accurately explore the growth and repr...
