Abstract
The invention relates to the technical field of aquaculture, in particular to an environment-friendly method for rearing prawn by utilizing chaetoceros. The method comprises the following steps of: rearing prawn larvae in a rearing pool; and adding nutrients and chaetoceros needed by the larvae at each rearing stage in the whole larva rearing process until the larvae grow up, wherein 0.2-1.2 million/ml of chaetoceros are kept in the rearing pool. On the basis of rearing the prawn larvae by effectively utilizing an ecological water environment mainly containing the chaetoceros, the invention realizes the zero pollution of the ecological environment by only adding water without draining, does not use any antibiotic and truly realizes environment-friendly and healthy production of the prawn larvae.
Description
Technical field
The present invention relates to technical field of aquaculture, is a kind of environmental protection prawn seed-rearing method of utilizing Chaetoceros specifically.
Background technology
Along with the development of culture fishery, its influence to ecotope more and more receives publicity.In recent years, the element of environmental protection is more and more considered in the improvement of aquaculture technology, has invented technology such as totally-enclosed, cycle water, zero blowdown in succession, and these technology have more been used through engineering approaches, and major part is based upon on the basis of renewal of the equipment.Utilize relation between the biology merely, realize that by setting up a controlled friendly ecosystem prawn seed-rearing technology of environmental protectionization also is not developed.
Summary of the invention
The object of the present invention is to provide the prawn seed-rearing method of utilizing Chaetoceros of a kind of practicality, environmental protection.
For achieving the above object, the technical solution used in the present invention is:
A kind of prawn seed-rearing method of utilizing Chaetoceros: with the prawn larval culture in culture pond, each nurturing period in larval culture phase whole process is added required nutrient and the Chaetoceros of seedling, not draining is until finishing the whole cultivating process of prawn from nauplius to young three phases of shrimp; The Chaetoceros density of described interpolation maintains ten thousand/ml of 2-12 in culture pond.
Each nurturing period of described larval culture phase whole process is zoea stage Z1, Z2, Z3; Acanthosoma M1, M2, M3; Post larval P1, P2, P3.
Described zoea stage Z1, Z2, Z3 auxiliary throw something and feed spirulina and yeast; Acanthosoma M1, M2, M3 auxiliary throw something and feed spirulina, yeast and the fairy shrimp young; Post larval P1, P2, P3 auxiliary throw something and feed the fairy shrimp young and prawn slice.
The advantage that the present invention had:
1. the nurturing an environment of seedling-cultivating method of the present invention will effectively utilize a large amount of idle workshop cement pits of growing seedlings.
2. the survival rate of seedling of seedling-cultivating method of the present invention is stable, remains on 40%-60% substantially.
3. the Chaetoceros good palatability, the comprehensive nutrition that adopt of the present invention, it satisfies the physiological ecological demand that the prawn young grows.
4. seedling raising process of the present invention guarantees shrimp seedling drug residue free without antibiotic.
5. the present invention is effectively utilizing the ecological water environment based on Chaetoceros to carry out on the basis of prawn seed-rearing, realize zero of ecotope is polluted in the mode of only adding not draining of water, stop environmental pollution, need not use any antibiotic simultaneously, really accomplished the green health that the shrimp seedling is produced.
