Abstract
The invention belongs to the technical field of marine culture, and discloses a technical method for culturing high-yield healthy ecological sea cucumber seedlings with low cost under the ecological condition. The method comprises the following steps: placing a net cage in a sea area or a shrimp pond with small wind wave; placing an attaching base in the net cage; putting child sea cucumber larvae with the size of 2-3mm without drug; and culturing for 75-80 days to reach the sales standard. Compared with the existing sea cucumber seedling culture technology, the method is characterized in that production cost is greatly lowered, larvae morbidity and mortality are lowered, no drugs are added in the whole seedling culture process, the cultured seedling is strong, has small possibility of being ill, has high survival rate and is similar to wild seedlings in natural sea areas. According to the method, considerable economic benefit is brought for operators, a great quantity of strong and environmentally-friendly ecological seedlings are provided for farmers, and natural resources, such as energy and the like can be greatly saved. In addition, the method is pioneering in the ecological seedling culture of stichopus japonicus on a large scale by the net cages in the sea areas in northern China, and a new path is created for developing an ecological healthy culture mode.
Description
Technical field:
The invention belongs to the sea farming technical field, is low-cost a kind of technical method of cultivating the healthy and strong ecological sea cucumber seed of high yield under natural ecological condition.
Background technology:
Sea cucumber is listed in one of " eight kinds of sea food " from ancient times, and the good reputation of " marine genseng " is arranged.According to the study, the particularly northern apostichopus japonicus selenka of sea cucumber has the characteristics of high protein, low fat, low sugar, and very high edibility and medical value are arranged.In recent years, along with improving constantly and the enhancing of health care consciousness of living standard of urban and rural population level, the consumption demand of sea cucumber is constantly risen, and price rises steadily, and has driven the rise of holothruian cultures heat thus.
Stichopus japonicus (Apostichopus japonircus Selenka) mainly is distributed in Huang, Bohai Sea immediate offshore area, has higher nutrition, economic worth, is the main large breed variety of northern China.In the last few years, along with the fast development of holothruian cultures industry, the stichopus japonicus indoors artificial scale of growing seedlings constantly enlarged, and output improves constantly.Because the indoor culture seed has certain limitation, occurred surviving the winter that expense is big, cost is high, easily fallen ill, survival rate has been low, problems such as energy waste do not reach green, environmental protection, the ecological requirement of country to the food security aspect simultaneously yet.The present invention at sea or old shrimp pond throw net cage into and carry out ecological sea cucumber seedling and cultivate, utilize this seedling growing process, reduced production cost widely, reduced young death rate of the onset, do not offer medicine in the whole seedling raising process, the seed physique stalwartness of cultivating, be difficult for falling ill, the survival rate height, approach the wild seed of natural waters, it not only brings considerable economic for the operator, for the raiser provides a large amount of stalwartnesses, green ecological seed, and natural resourcess such as the energy have been saved widely, having started in the northern China sea area utilizes net cage to carry out the beginning of extensive stichopus japonicus ecological breeding, creating a new road aspect the developing ecology healthy aquaculture mode, its advance and practicality are conspicuous.
As a kind of typical marine economic animal, sea cucumber is grown seedlings and cultures the pillar industry that has become the coastal aquaculture of northern China, has attracted a lot of scholars, aquatic products professional and technical personnel's concern, put into wherein and study, produce, the cultural technique of growing seedlings level improves constantly.But these researchs mainly concentrate on the sea cucumber indoor raising of seedling, and the present invention utilizes outdoor net cage to cultivate ecological sea cucumber seedling, has remedied the deficiency of indoor raising of seedling, as abuse of antibiotics, the producing cost height, the production limitation is strong etc., and growing seedlings for sea cucumber provides a brand-new more wide development space.
Summary of the invention:
The object of the present invention is to provide a kind of more extensive, reduce production costs, method that ecological sea cucumber seed is produced in economic environmental protection.
Technical solution of the present invention is:
A, net cage is set.
B, input adherance.
The young ginseng young of c, input 2-3mm.
D, suitably change water according to the water quality situation.
E, change adherance according to the adherance operating position.
F, according to the penetrating situation of water inside and outside the net cage, change net cage or scrub net cage.
G, cultivation 75-80 days, seedling is long to 200-1000 head/500 grams, the sale of can emerging.
Compare with existing sea cucumber seedling growing process, the present invention has following advantage:
1, the seed cultivated of the present invention wild seed of approaching natural waters, the physique stalwartness, be difficult for falling ill, the survival rate height.
2, the sea cucumber seed fast growth of Pei Yuing, specification is big, does not offer medicine, economic environmental protection.
3, more extensive cultivation sea cucumber seedling has reduced production cost, has saved the human and material resources and the energy.
Embodiment:
The invention will be further described below by specific embodiment
Embodiment one, the setting of outdoor net cage
1, the net cage place selection is set
At the bottom of the net cage setting should be chosen in the less inner bay substrate of stormy waves and is sandstone, as utilize idle shrimp pond to select can the retaining degree of depth more than 2 meters, substrate is harder, retaining is the pond easily.
2, net cage setting
(1) cage size is made net cage and should be selected quality 40 mesh sieve tulles preferably, makes the net cage of 2 * 2 * 4 meters top openings.
(2) net cage is installed, and uses 4 meters waters that are fixed on setting that long rod is in a row with net cage, and net cage is suitable for reading to surface, and goes to the bottom apart from the pond.
Claims (7)
1. the outer net cage biological breeding method of sea cucumber seedling room is characterized in that having the following steps:
