Abstract

The invention discloses an ecological polyculture method for portunus trituberculatus mainly cultured in a pond. The method is characterized by comprising the steps of cleaning the pond, culturing ruditapes philippinarum, fenneropenaeus chinensis and the portunus trituberculatus, feeding bait and the like. By using ecological complementarity of the ruditapes philippinarum, the fenneropenaeus chinensis and the portunus trituberculatus for polyculture, the method of the invention fully utilizes the natural bait, increases the spatial stratification of the ecological structure of the culture pond, improves the stability of the environment of the culture pond and solves the problems of cannibalism of the portunus trituberculatus, insufficient bait, diseases, degradation of water quality and the like during the culturing, so that the technical effects of high yield, high efficiency and environmental protection are realized.

Description

technical field [0001] The invention relates to an aquatic polyculture method, in particular to an ecological polyculture method for mainly raising portunus trituberculatus in ponds. Background technique [0002] At present, Portunus trituberculatus has been artificially cultured in all coastal provinces of my country, especially in Shandong, Jiangsu, Hebei and other provinces where the scale of cultivation is relatively large. The single-species high-density culture of Portunus trituberculatus used in my country in the past generally has problems such as serious cannibalism of Portunus trituberculatus, low aquaculture output, insufficient bait utilization, deterioration of aquaculture water quality, and no guarantee of product safety; Explosive epidemics are easy to occur, the utilization rate of resources is low, and the damage to the natural environment is great, which is not conducive to the sustainable development of Portunus trituberculatus aquaculture.
