A kind of intensive culture system and culture method of Dermocystis spp. in ponds

Abstract

The invention discloses a pond intensive culture system and a culture method of Dermocystis cerevisiae. The system includes a water storage area and a breeding area, and an inlet and drainage ditch is arranged between the two; two water storage tanks are arranged in the water storage area, and the water storage tanks are surrounded by a water storage tank embankment and a water storage tank. ditch and the central beach surface, and the central beach surface is stocked with razor clams; several culture ponds are provided in the culture area, and the culture ponds are composed of culture pond embankment, culture pond ring ditch, culture pond longitudinal ditch and cheng. On the said cheng, the delicious Dermocystus is stocked; one end of the reservoir and the breeding pond is provided with the inlet and outlet I and the inlet and outlet II that are connected with the inlet and outlet ditch. The cultivation method of D. pallidum using the system includes technical links such as preparation for stocking, stocking of seedlings, mid-term separate breeding, breeding management, harvesting and the like. The invention miniaturizes the breeding pond, is convenient for intensive breeding operation and management, has high breeding survival rate and good quality, and can harvest clam razor clams while harvesting the tasty saccharomyces, which significantly improves economic benefits.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a pond intensive culture system and a culture method of Dermocystis spp. Background technique [0002] Dermocystis spp. is one of the important economic species of Astrozoa. It is mainly distributed in the southeast coast of my country. It inhabits the intertidal zone and lives in caves. It feeds on benthic diatoms and organic debris. It has the functions of nourishing yin and reducing fire, tonifying kidney and improving intelligence, anti-aging, anti-fatigue, anti-radiation, etc., so it is known as "animal ginseng" or "cordyceps sinensis" in the sea. Derma spp. has strong adaptability to the environment, miscellaneous feeding habits, and is easy to breed. It is an ideal high-quality breeding species. [0003] The breeding technology of D. couscous has been reported. Invention patent application CN 106665504A discloses a high-yield breeding method of Derma spp....

AI Technical Summary

Problems solved by technology

[0004] However, there are the following deficiencies or defects in the above D. pallidum culture technology: 1. the cultivation pond area is relatively large, which is unfavorable for the implementation of intensive cultivation and good cultivation management; The density is too high to affect the growth, which is not conducive to the production of large-scale D. californica products; ③ farm manure such as chicken manure is applied during the breeding process, which affects the quality and safety of the cultured products of D. And directly discharged, polluting the surrounding water environment
