The studies on the Ecology of twenty species Fishes in Fujian coastal waters

This paper studied the population structure and the parameter of growth and mortality and the exploitation rate of twenty species fishes in Fujian coastal waters. Their optimum fishing standard and minimun fishing standard were calculated. The change of the fisheries resources in the waters and the population structure and the index of ecology of major species were also analysed. Because of the grievous injury of the economic young fish from fishing, the importance of the minimun fishing standard to carry out are put forward. The protective measure of economic young fish are also discussed.
