Intermediate aquaculture system for pinctada maxima

Abstract

The invention discloses an intermediate aquaculture system for pinctada maxima. The intermediate aquaculture system comprises an outer ring slot and an inner slot formed by encircling the outer ring slot, wherein a communicating plate, a water level plate, a screen and a baffle are arranged in the outer ring slot; a clearance is reserved between the bottom of the communicating plate and the bottom surface of the outer ring slot; the water level plate and the baffle are plugged in the outer ring slot to form a filtering water chamber; the screen covers the top of the filtering water chamber and is inclined from the water level plate to the baffle; a sewage drain pipe is arranged at the lower end of the screen; an attachment device for attaching beneficial bacteria is arranged in the inner slot; a clean water outlet communicated with an aquaculture region is formed in the slot wall of the inner slot; water in the aquaculture region flows into the filtering water chamber after being filtered by the screen and then is extracted to the inner slot; by beneficial bacteria purification treatment, the water flows into the aquaculture region from the clean water outlet so as to realize water body circulation. The intermediate aquaculture system for pinctada maxima can be used for automatically purifying aquaculture water, so that the water quality can be kept in a good state for a long time; therefore the water change frequency is reduced, irritation to pinctada maxima stress is alleviated, and loss of bait algae along with water drainage is also reduced, so that the supply of baits is reduced, and the labor intensity is correspondingly reduced.

Description

technical field [0001] The invention relates to an aquaculture system, in particular to an intermediate cultivation and cultivation system of pearl oyster. Background technique [0002] Pearl oyster, commonly known as white butterfly oyster, is a national second-class protected aquatic animal and the largest marine pearl oyster. Large pearl oyster can produce large pearls with strong luster and beautiful color, which has high economic value and scientific research value. However, the large pearl oyster is extremely harsh on the survival and growth environment, and is easily affected by changes in water temperature, seawater quality, salinity, dissolved oxygen, and light intensity. After the death phenomenon, it is difficult to break through 3-5 cm in the cultivation of large pearl oysters in natural sea areas. At present, the transfer of large pearl oyster from natural sea area culture to indoor culture that can artificially control the environment has become the main dire...
