Embodiment

[0015] Chlorine disinfection (available chlorine 15 mg / L) was carried out to the water in the nursery pond for cultivating prawn larvae, and after sedimentation for 48 hours, the pretreatment was completed by filtering in a sand tank.

[0016] Then use the 30 cubic meter cement pool in the nursery as the cultivation tank, inject the pretreated seawater in the nursery tank, the pretreated seawater 60cm in the nursery tank, and inflate the nursery tank with residual chlorine. Put prawn nauplii (N5-N6) (the 5th to 6th stage of development of nauplius) in the nursery pond, and the density of larvae is 150,000 tails / cubic water body. After the larvae are released, add Chaetoceros 10cm.

[0017] Add 10cm of Chaetoceros algae water when the seedlings are in the Z1 stage of the zoan larvae, so that the density of Chaetoceros in the culture tank can be maintained at 80,000-90,000 / m1; the water temperature is 30°C, and a small amount of aeration is maintained. The Z1 cultivation period ...

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 [0001] The invention relates to the technical field of aquaculture, in particular to an environment-friendly prawn nursery method using chaetoceros. Background technique [0002] With the development of aquaculture industry, its impact on the ecological environment has attracted more and more attention. In recent years, more and more elements of environmental protection have been considered in the improvement of aquaculture technology, and technologies such as fully enclosed, circulating water, and zero sewage have been invented successively. These technologies are more engineering-based, and most of them are based on equipment renewal basis. The shrimp nursery technology that realizes environmental protection by simply utilizing the relationship between organisms and establishing a controllable and friendly ecosystem has not yet been developed. Contents of the invention [0003] The purpose of the present invention is to provide a practical and environme...
