Embodiment 1

[0041]A sea cucumber seed breeding method, comprising the following steps:

[0042] 1. Species screening

[0043] In November of the Gregorian calendar, choose shallow sea wild ginseng with an individual weight of more than 250g as the species;

[0044] 2. Seed ginseng is cultivated by raising temperature to promote ripening, and cultivating at constant temperature for production

[0045] (1), density and temperature control

[0046] During the storage period, the density of ginseng in the storage pond is controlled at 15-20 heads / m 3 , the dissolved oxygen concentration in the storage pond is controlled at 5-8mg / ml, and the temperature of the ginseng is raised to promote the ripening cultivation, that is, it enters the pond in the middle of January in the Gregorian calendar. Growth: After the ginseng enters the pool, the water temperature is controlled at 2-3°C and kept for 2-3 days. After that, the temperature is raised by 1°C every day. When it rises to 6°C, it is incuba...

Abstract

The invention relates to a method for breading Stichopus japonicus seedlings, which belongs to the technical field of Stichopus japonicus culturing and comprises the following steps of screening Stichopus japonicus seedlings, heating and accelerating culturing of the seedlings, culturing at a constant temperature for lying-in, fertilising and hatching the laid eggs, culturing the larva, culturingthe young Stichopus japonicus, aerating, reserving pond and changing sheets. The healthy and high quality Stichopus japonicus seedlings cultured by the method can be matured 2-3 months earlier than that of the Stichopus japonicus seedlings in the natural sea areas, therefore, the thermophilous growth period of the Stichopus japonicus seedlings in the same year can be prolonged; technical measuressuch as water quality regulating and controlling, scientific bait casting, biological disease prevention and the like are adopted in the method to culture the healthy Stichopus japonicus seedlings; with the adoption of the measures such as temperature controlling, light controlling, enforced bait casting and the like, the culturing method can effectively prevent and cure diseases from the culturing of the Stichopus japonicus seedlings to the delivery of the large-scale Stichopus japonicus seedlings, so that high-intensity breeding of the seedlings can be realized and the survival rate from the young Stichopus japonicus to the commercial Stichopus japonicus can reach 80% to 90%.

Description

technical field [0001] The invention relates to a method for breeding sea cucumber seedlings, belonging to the technical field of sea cucumber cultivation. [0002] Background technique [0003] In recent years, sea cucumber cultivation has developed rapidly, and sea cucumber seedlings have also developed accordingly. The original nursery rooms for other seafood have begun to raise sea cucumber seedlings, but the seedling output is 2-6kg / m 3 , there are many reasons for this. At present, there have been reports about industrialized seedling cultivation of sea cucumbers in China: (1) In 1976, the artificial seedling cultivation and multiplication technology of sea cucumbers were successfully developed in Yantai, and won the National Science and Technology Conference Award in 1978. With the in-depth research on the law of artificial seedling cultivation and the improvement of technology, the emergence of juvenile ginseng per unit of water continued to increase. By 1982, the ...
