Abstract:How does the filter feeding mollusk influence the ecosystem of polybasic composite cultivation? This paper deals with the studies on this question in recent years and concludes the following:(1) The filter feeding mollusk survive on the phytoplankton, other microorganisms and some crumb of organism. They feed so much everyday that there has an enormous feeding pressure on the ecosystem which leads to the descent of phytoplankton's biomass;(2)The cultivation excrement and the excrement discharged by the mollusk result in biodeposition ,which enhance the activity of the microbe in the substratum and make an non oxygen or oxy sparse surrounding .At the same time ,the activity of biodeposition accelerate the release of inorganic salts.So biodeposition has a great effect on the structure and function of the ecosystem and is able to change the population composition of the benthos ;(3)The increase of the inorganic salts fertilizes the water in ponds, which will be good for the microphytoplankton to grow and reproduce because of its adaption and will inhibit the growth of miniphytoplankton and some pelagic protozoa for their maladjustment. Some bigger zooplankton and Copepoda are less accessible;(4) the model of polybasic composite cultivation which makes the living space of the zoo isolated relatively and makes the niche combine with each other has greater efficiency than other models do if managed well.
Keywords:composite cultivation  ponds of Penaeus cultivation   filter feeding mollusk   effect on the ecosystem  Penaeus
