Embodiment Construction
[0014] Such as figure 1 A purple sea urchin multiplication and release research device shown in the figure includes a plastic basket 1 with an open upper end. The plastic basket 1 is the frame of the entire device, and its size is length×width×height=450mm×320mm×120mm. At the bottom of the plastic basket 1 Offer some hydrophobic holes 2 on the surrounding wall, be convenient to water body exchange and sufficient bait can enter in the frame.
[0015] The inner wall of the plastic basket 1 is fixedly laid with a beam mouth net bag 3 whose size is length×width×height=450mm×320mm×240mm. Putting the purple sea urchin seedlings into the initial stage of research, because the shell diameter of the purple sea urchin seedlings is small, if the purple sea urchin seedlings are directly placed in the plastic basket 1, it will cause escape. Bottom four limits of beam mouth net bag 3 and four limits of height direction are all fixed on the plastic basket 1 with iron wire, and the size of m...

The invention relates to a purple sea urchin multiplication and release research device, which comprises a plastic basket with an open upper end, a sealing piece is provided on the upper end of the plastic basket, a number of hydrophobic holes are opened on the wall of the plastic basket, and bundles are fixedly laid on the inner wall of the plastic basket. The mouth net bag is provided with a perching board at the bottom of the beam mouth net bag, and a wavy perching surface is formed on the surface of the perching board. The girth net bag laid in the plastic basket not only provides the living space of the purple sea urchin but also prevents the purple sea urchin from escaping. The hydrophobic holes on the plastic basket are convenient for water exchange and bait entry, and the perch board is provided with wavy habitats. It greatly increases the attachment area of purple sea urchins, which is conducive to its attachment and life. When it is necessary to observe and study the survival rate, growth and reproduction of purple sea urchins after proliferation and release, you can directly observe or take out the beam mouth net from the plastic basket. Bag for research and analysis, very simple and convenient to use. The invention can be applied to the monitoring research on the proliferation and release effect of purple sea urchins.
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...
