Embodiment 1

[0021] In this example, juvenile giant clams were cultured from the applicant's breeding base in Sanya. The case was implemented from May to July 2016, and the species of giant clam was giant clam. 20 days after the metamorphosis of artificial breeding, transplanted to massive coral stones, the total water used for breeding is 30m 3 , a total of 5 fiberglass pools, wherein 3 fiberglass pools use the filamentous algae comprehensive prevention and control method of the key technology for the intermediate cultivation of giant clam juveniles of the present invention to carry out filamentous algae prevention and control, and the other 2 fiberglass pools adopt conventional methods for intermediate cultivation so that refer to.

Embodiment 2

[0034] In this example, juvenile giant clams were cultured from the applicant's breeding base in Sanya. The implementation time of the case was from June to August 2017. The species of giant clam was Tridacna safflower. 20 days after the metamorphosis of artificial breeding, transplanted to massive coral stones, the total water used for breeding is 30m 3 , a total of 5 fiberglass pools, wherein 3 fiberglass pools use the filamentous algae comprehensive prevention and control method of the key technology for the intermediate cultivation of giant clam juveniles of the present invention to carry out filamentous algae prevention and control, and the other 2 fiberglass pools adopt conventional methods for intermediate cultivation so that refer to.

Abstract

The invention discloses a comprehensive filamentous alga prevention and control method for an intermediate culture key technique of tridacnidae young shellfishes. The method comprises the following steps: (1) carrying out light-shading culture in a culture stage of the tridacnidae young shellfishes by virtue of purple blue light-transmission corrugated tiles, wherein the wavelength of light is controlled during the culture, and the illumination intensity range is 6000Lux-15000Lux; (2) maintaining seawater for culturing the tridacnidae young shellfishes at normal salinity and temperature, maintaining KH of a seawater body at 8-10, and maintaining pH of the seawater body at 8.0-8.5; (3) adding denitrifying bacteria and bacillus into the seawater at a fixed period of one week; and (4) when finding that brown or green spot algae occur in a culture pool and have the trend of expanding day by day, adding dried Chinese lobelia herb into the culture pool, if dead organisms are found, timely picking out the dead organisms, and carrying out proper processing. According to the comprehensive filamentous alga prevention and control method, break-out of filamentous algae can be effectively inhibited, so that the success rate of intermediate culture of the tridacnidae young shellfishes is remarkably increased; and the comprehensive filamentous alga prevention and control method has multiple characteristics of relatively low cost, good effect, easiness in execution and the like.

Description

technical field [0001] The invention belongs to the field of artificial cultivation of giant clam shellfish in the marine aquatic industry, and in particular relates to a method for comprehensive prevention and control of filamentous algae which is a key technology for the intermediate cultivation of juvenile giant clam shellfish. Background technique [0002] Tridacna is the largest species of marine bivalve mollusk belonging to the clam order, family Tridacnidae (Tridacnae) of the genus Tridacna or the genus Tridacna. Distributed in the tropical and subtropical oceans of the Indian Ocean and the Pacific Ocean, especially in the South China Sea, the Philippines, Indonesia and Australia. In my country, it mainly exists in the coral reef areas of Nansha Islands, Xisha and Hainan Island, and is one of the main functional organisms of coral reefs. The maximum shell length of giant clams is recorded to be 1.8 meters, and the weight exceeds 300 kilograms. The growth rate of gian...
