摘要: 通过2000年象山港网箱养鱼区和邻近对照区的4季采样,对该区大型底栖生物进行了分析研究,共鉴定出大型底栖生物41种,网箱养鱼区周边种类39种,对照区9种,约占象山港总种数的58%,网箱养鱼区周边生物量和密度(91.92g/m2和114.96个/m2)明显高于对照区(10.61g/m2和48个/m2).在网箱养鱼区周边沉积物中主要因子均高于对照区,其中硫化物高出4倍多,在网箱养鱼区周边硫化物较低的站位生物量较高,而在网箱养鱼区中央沉积物年均累积速率约25cm,已成黑色并有浓烈异味,未见大型底栖生物分布.Abstract: Seasonal investigations were carried out on a fish net-cage cultural area and a contrasting area.41 species from study areas were identified.39 species were collected from the cultural area and 9 species from the contrasting area.No any macrobenthos species was found in the center of fish net-cage cultural area.The average biomass and density in the net-cage cultural area are 91.92 g/m2 and 115 ind/m2,higher than those in the contrasting area(10.61 g/m2 and 48 ind/m2).They are change obviously with the variety of season.Community structure in the net-cage cultural area is more complex than the contrasting area.Main environment factors in the net-cage cultural area such as sulfide and organic compound are higher than the contrasting area.Relationship of macrobent hos and environment factors is discussed.There was not any macrobenthos in the center of fish net-cage cultural area in which the sediment was piled up at the rate of 25 cm/a.
