Abstract

In order to explore the impact on water quality and economic benefit of polyculture mode, bred Panopea generosa with Oncorhynchus mykiss , Pseudopleuronectes yokohamae, Acanthopagrus schlegelii, Sebastodes fuscescens and Scophthalmus maximus in outdoor pond from March to May 2013 in Penglai Zongzhe Breeding Co. Ltd.. The results showed that: The water quality factors (NH4+-N, NO2--N, NO3--N, COD, DO) were in line with nuisanceless water quality standards; Water temperature in pond was 3 ~ 7 higher than natural water due to adopting indoor circulated water technology, which speeded up the growth of fishes; The output value reached 2.0337 million yuan after nearly 20 months of cultivation, the total profit and unit profit was 757, 900 yuan and 126, 300 yuan/acre respectively; The ratio of investment on output value was 1:1.594, so the company won 59.41% of economic benefit. Polyculture effect of Panopea generosa and marine fishes was well.
