Problems solved by technology

In recent years, sea cucumber farming has developed rapidly, and sea cucumber seedlings have also stepped into industrialized seedlings and intensive farming. Industrial farming requires high-density breeding and large-scale seedlings. In the past, sea cucumber seedlings were mostly raised in sea cages, and the ovulation and ovulation of seedlings were less. Lack of a complete implementation method for intensive cultivation of sea cucumber larvae

Embodiment

[0025] A method for cultivating sea cucumber larvae, comprising the following steps:

[0026] 1), density control

[0027] The breeding density of ear-shaped larvae is controlled at 0.15 / ml-0.2 / ml, the pool water temperature is controlled at 20-23°C, and the optimal density of salivary larvae is controlled at 0.1 / ml-0.15 / ml.

[0028] 2), bait control

[0029] The feed in the planktonic stage is mainly single-celled algae, which is any one or several of the small crescent, Chaetoceros, salina, and Nishiki; at the same time, a certain amount of marine red yeast, spirulina powder, and fresh yeast , in order to diversify the species, the weight ratio of unicellular algae, marine red yeast, spirulina powder, and fresh yeast is: 100: (20-60): (20-60): (20-60); The feeding amount adheres to the principle of less input and more frequent input. Microscopic examination is performed before each feeding, and the amount of feeding is determined according to the amount of stomach content....

Abstract

The invention relates to a method for breeding juvenile Apostichopus japonicus and belongs to the technical field of sea cucumber culture. The method comprises the following steps: (1) carrying out density control; (2) carrying out feedstuff control; (3) carrying out adhering apparatus drop-off; (4) carrying out inflation; (5) carrying out pond changing; and (6) carrying out sheet changing. According to the method, through taking the measures of controlling temperature, controlling light, strengthening feeding, and the like, diseases can be effectively prevented and treated, and the high-density breeding of offspring is achieved; and healthy juvenile Apostichopus japonicus is bred by taking the technical measures of carrying out water quality regulation and control, carrying out scientific feeding, carrying out ecological disease prevention, and the like. The utilization ratio of water is effectively increased, the disadvantages of the traditional extensive culture are overcome, the quality of cultured Apostichopus japonicus is adequately guaranteed, and the factory, industrialized and modernized culture of the Apostichopus japonicus is promoted.

Description

technical field [0001] The invention relates to a method for cultivating sea cucumber larvae, belonging to the technical field of sea cucumber cultivation. Background technique [0002] The nutritional value of sea cucumber is high, it contains protein, fat, carbohydrates, calcium, phosphorus, iron, and vitamin B1, B2, niacin, etc. Sea cucumber has certain characteristics in composition, that is, it contains extremely low cholesterol and relatively little fat content. It is a typical high-protein, low-fat, and low-cholesterol food, which is especially suitable for patients with hypertension, hyperlipidemia and coronary heart disease. It is not only a delicacy on the banquet, but also a treasure to nourish the human body, and its market demand is increasing. In recent years, sea cucumber farming has developed rapidly, and sea cucumber seedlings have also stepped into industrialized seedlings and intensive farming. Industrial farming requires high-density breeding and large-s...
