| 内容記述 | The environmental characteristics of fishery grounds were surveyed 4 times a year from 1992 to 1994 during the ebb tide in Hiroshima Bay and in the Inland Sea area of Yamaguchi Prefecture, to evaluate the productivity of the clam, Ruditapes philippinarum. Temperature, salinity, dissolved oxygen content and pH of exuded water, particle size distribution of the substrata, total sulphide content, ignition loss, chlorophyll-a content and pheo-pigment content of the soil were determined. Artificially produced and marked clams of about 10 mm size in shell length were released in each fisheries ground simultaneously in 1993 and in 1994. The growth and survival rates of the released clams were estimated to evaluate clam productivity in each fishery ground. Also the faunal composition of the benthos at each station where the clams were released was examined visually using animals retained on 5 mm mesh filter. The survival and growth of released clams were comparatively high in the fisheries grounds where the substratum was not disturbed by wave and wind action and maintained an equilibrium between influx and outflux of materials of primary production, although, judging from environmental characteristics, they are basically eutrophicated tidal flats. On the other hand clams disappeared by several months after release in the other fisheries grounds, although growth was not significantly reduced compared to the populations in the former fisheries grounds. Reasons for this include that the current frequently disturbed the bottom substratum and repeated renovations of substratum surface resulted the relative increase of chlorophyll-a content. We speculate that the optimal manner of management of clam resources will depend on the environmental characteristics of each fisheries ground. Management should be focussed on the environmental conditions of the fishery grounds in the eutrophicated and more stagnant fields, and stock management would be most useful in sandy beach type fishery grounds. | |||||||||||||||||||||||||||||
