Abstract

The invention discloses a subsurface-flow water supply culture method of Babylonia, belonging to the technical field of aquiculture. The method comprises the following steps of: (A) establishing a subsurface-flow culture pond of the Babylonia; (B) spreading Babylonia larvae on a supporting nozzle plate for culturing, and spreading a layer of sand grains on the Babylonia larvae layer; (C) enabling natural sea water or artificial sea water to flow into the culture pond through a water inlet pipe from the lower part of a culture medium; and (D) refreshing the natural sea water or the artificial sea water in the culture pond once through the water inlet pipe and a water outlet pipe every 3-7 days until the culture period of the Babylonia finishes. The invention also discloses a subsurface-flow water supply culture device of the Babylonia. The culture method of the invention does not depend on microorganisms to purify the culture environment but directly purifies and controls the culture environment through water flow and air inflation. In the culture process, sand grains of which the average diameter is 2mm-10mm are selected, thereby greatly enhancing the water flow permeability of the sand layer and effectively reducing the occurrence of Babylonia diseases.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a submerged water-supply culture method and a device thereof for marine sand-submerged shellfish such as Dongfeng snails. Background technique [0002] The existing cultivation of sand-submerged shellfish, especially the cultivation of Dongfeng snails, mainly utilizes the self-purification mode of the sand layer for cultivation. The sand layer was inoculated with microbial flora capable of purifying the excrement of submerged shellfish such as Dongfeng snails in order to purify their excrements and create a suitable growth environment for Dongfeng snails and the like. Because the excrement of Dongfeng snails and other species is accumulated in the sand layer, and the sand layer has poor permeability, it is difficult to effectively decompose and discharge the excrement even if it is inoculated with microbial flora, especially in high-density, long-flowing aquacultu...
