Method for solving problem of biological deposition of sand-bottom stichopus japonicus aquaculture pond by aid of biological functions

Abstract

The invention discloses a method for solving the problem of biological deposition of a sand-bottom stichopus japonicus aquaculture pond by the aid of biological functions. The method can solve problems that an effect for improving biological deposition of a sand-bottom stichopus japonicus aquaculture pond is poor in the prior art, a sedimentary environment of the stichopus japonicus aquaculture pond cannot be effectively improved, diseases of stichopus japonicus cannot be prevented and the like. The method is characterized in that certain quantities of penaeus japonicus, fenneropenaeus chinensiss, ruditapes philippinarum and sinonovacula constricta are fed into the stichopus japonicus aquaculture pond, an effect of loosening the bottom of the pond is realized owing to sand diving functions of the penaeus japonicus, the fenneropenaeus chinensiss, the ruditapes philippinarum and the sinonovacula constricta, organisms such as nereid and copepoda in the aquaculture pond are ingested by the penaeus japonicus and the fenneropenaeus chinensiss, and residual feeds, organic detritus, humus, fungi and the like are subjected to filter-feeding by the ruditapes philippinarum and the sinonovacula constricta. Accordingly, the method has the advantages that the purpose of improving a sedimentary environment of the aquaculture pond is achieved, and the problem of biological deposition of the aquaculture pond is solved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for solving biodeposition in sand-bottom japonicus culture ponds by using biological functions. Background technique [0002] In recent years, with the vigorous development of marine aquaculture, the scale of pond aquaculture is expanding year by year, especially the upsurge of sea cucumber pond aquaculture that has emerged in recent years, with a rapid development momentum and a continuous growth trend. [0003] Although the upsurge of sea cucumber culture in ponds has greatly improved the national fishery output value, its own problems have gradually emerged. High-density sea cucumber culture in ponds has caused the accumulation of excreta and residual bait of sea cucumbers and the accumulation of algae. The organic debris produced by the rotting and falling off of the body forms pond biodeposits, and the biodeposition (C.N.P) after burial and mineraliz...
