象山港海洋牧场示范区渔业资源的时空分布
Spatial and temporal distribution on fishery resources of marine pasture demonstration area in Xiangshan Harbor
摘要
Abstract
Based on the data from tow-quarter fishery survey in 2010, the spatial and temporal distribution, community structure, resource density of sea fishery resources in XiangShan Harbor demonstration plot were analyzed. The survey altogether found 63 catches, including 29 species of fish, 19 of shrimps, 12 of crabs, 3 of shellfish. The number of species, quantity and quantity catches, quantity and quantity of resource density in Summer were significantly higher than that in Spring. The average density of the resources in two quarter, crabs was the highest In quality of varieties, for 78. 864 kg o km-2 , followed by shrimp, fish, cephalopods; in the average density of the resources across the varieties, shrimp is the highest, about 2. 976 5×104 ind o km-2, followed by fish, crabs, cephalopods. Fish content in appeared yellow croaker, anchovy, sea ell fish, but quantity scale economy relatively low, and low economic value, a goby fish a larger share of fishery resources, to development trend overall individual miniaturization. There is a close relationship in the harbor of fishery resources types and diversity pattern form between its terrain and hydrological features. Marine ecological quality of the overall pollution level was moderate, and this was a serious trend, which may be disturbed by human's activities or over-fishing. We suggest to proper control fishing intensity or fishing time, strengthen education of policies and regulations on the fishermen and increase the discharge and o-cean ranch proliferation efforts to launch to the protection of the resources, That is of far-reaching significance.关键词
