Feeding method of reducing disease and insect pest occurrence of stichopus japonicus

Abstract

The invention discloses a feeding method of reducing the disease and insect pest occurrence of stichopus japonicus. The method comprises the steps of building a stichopus japonicus feeding pond and a substratum; building the pond suitable for the growth of the stichopus japonicus and throwing stichopus japonicus seedlings into the pond by combining with the actual conditions according to the biological habit requirements of the stichopus japonicus; under the general condition, the state that big seedlings of over 600 heads/kg are thrown in the pond in a specification of 10 heads/m<2> to 20 heads/m<2> is proper, and if the specification is larger, the throwing amount in unit area can be smaller; the feeding feed formula comprises 20-25 parts of animal protein hydrolysate dry powder, 15-20 parts of meat and bone meal, 20-22 parts of soybean meal, 4-6 parts of honeysuckle, 2-3 parts of medicated leaven, 3-5 parts of angelica sinensis, 2-3 parts of soya bean lecithin, 1-2 parts of alginate-derived oligosaccharide, 1-2 parts of vitamin C, 1-2 parts of spirulina, 2-3 parts of lupulus, 3-5 parts of tea saponin, 2-3 parts of fructus cnidii, 3-4 parts of fructus ulmi, 1-2 parts of golden larch bark. The management of the stichopus japonicus seedlings is that when winter comes, the water depth of the pond is properly increased, and the change of dissolved oxygen and substrate and the prevention and control of seaweeds must be paid attention to; when the water temperature of the pond rises at spring, the transparency of the water is reduced by fertilizing the water, and the breeding of the seaweeds is controlled.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a cultivation method for reducing the occurrence of diseases and insect pests of japonicus japonicus. Background technique [0002] Sea cucumber, as a kind of sea treasure, plays an important role in providing food, drug raw materials, nutrition and health food. Sea cucumber (Apostichopus japonicus) is the species with the best quality, the widest distribution and the largest yield among domestic edible sea cucumbers. Its breeding areas are mainly distributed in Liaoning, Hebei, Shandong and the northern coastal areas of Jiangsu. In the 1980s, the artificial breeding technology of sea cucumbers in my country had a breakthrough, and a relatively complete production technology system has been formed so far. The area of ​​japonicus breeding continues to expand. The area of ​​japonicus breeding in Shandong and Liaoning is more than 30,000 m2, and the output value exceeds 10 billion yuan. Ho...

Problems solved by technology

After summarizing the practical experience of sea cucumber cultivation in ponds for many years, it is found that the main reasons for the above phenomenon are the low standard of existing sea cucumber ponds, non-standard breeding methods, lack of popularization of many advanced technical measures, and lack of scientific and reasonable feed formula
