Energy-saving and emission-reducing seedling raising method of blue dress sea urchin

Abstract

The invention discloses a seedling raising method of blue dress sea urchin. Compared with the traditional sea urchin seedling raising method, a large number of blue dress sea urchin seedlings can be cultivated under the conditions of extremely low energy consumption and aquaculture wastewater discharge, so as to reduce natural resources The purpose of solving the problems of high transportation costs and low survival rate. First of all, it puts the breeding environment in the greenhouse. Under the action of the greenhouse, the water temperature of the breeding water body is kept in a relatively high range. It does not use artificially heated seawater for seedling cultivation. On the premise of saving costs, boilers are avoided. It will cause pollution to the environment; at the same time, in the cultivation process, the larvae are cultivated under light in the range of 1500~2500 lx, and Chaetoceros mouvii and seawater photosynthetic bacteria are put in, which can achieve the purpose of purifying water quality and avoid large quantities and frequent water changes. cost issue.

Description

technical field

[0001] The invention relates to the field of sea urchin breeding, in particular to a method for raising seedlings of blue dress sea urchins with energy saving and emission reduction. Background technique

[0002] Blue dress sea urchin ( Mespilia globulus ) belongs to the phylum Echinodermata, class Echinacea, order Orthomorpha, family Carteridae, English name Blue Tuxedo Urchin. Distributed in the Indian Ocean, the Pacific Ocean, and the South my country Sea to the southern waters of Japan. The shell of the blue dress sea urchin has five wide blue or black veins, and the thorns are red, brown or black. Widely grown in marine aquariums.

[0003] The blue dress sea urchin is in great demand in the market. At present, the blue dress sea urchin sold in the domestic aquarium market is naturally caught in tropical seas such as the Indian Ocean, and transported to the destination by air. The high cost of fishing and transportation makes the price of a blue dress ...
