Energy-saving and emission-reducing breeding method for Pincushion Urchin

Abstract

The invention discloses a breeding method for Pincushion Urchin. Compared with a traditional sea urchin breeding method, a large number of Pincushion Urchin larvae can be bred under the quite low energy consumption and culture wastewater discharge conditions so as to achieve the purposes of reducing natural resource fishing and catching pressure, and the problems that the transportation cost is high and the survival rate is low are solved. The method comprises the steps that firstly, a greenhouse is adopted as the breeding environment, under the effect of the greenhouse, water temperature of culture water is kept within the large range, no artificial heating seawater is adopted for breeding, and under the condition of saving the cost, pollution caused by a boiler to the environment is avoided; meanwhile, in the cultivation process, illumination within the range of 1,500-2,500 lx is adopted in the breeding process for culturing larvae, Chaetoceros mulleri and seawater photosynthetic bacteria are put, the purpose of purifying water can be achieved, and the problem that the cost is caused when a large amount of water is changed frequently is avoided.

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 bred 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 s...
