This paper describes the evolution of the life history patterns for main marine fishes such as hairtail Trichiurus haumela (Forskal), small yellow croaker Pseudosciaena polycactis Bleeker,large yellow croaker P. crocea (Richardson),filefish Navodon septentrionalis Gunther,herring Clupea harengus Pallasi, spanish mackerel Scomberomorus niphonius (Cuvier et Valenciennes), mackerel Pneumatophorus japonicus Houttuyn, harvestfish Pampus argenteus (Euphrasen) and Chinese herring Ilisha elongata (Bennett). The relationships between life history patterns and populations dynamics are compared and summerized as follows. The population structure has become simpler. Formerly the remainder dominated spawning stock but recently recruitment of stock exceeds the remainder. For large yellow croaker the remainder of the stock exceeds the recruitment. Maturation is usually spread over several years and the composition was of complicated structure in the 1950s.The life spans of the large and small yellow croakers which could reach to twenty nine and twenty three years in the 1950s, decreased to seven and two years respectively. With the change of the stock structure the life history patterns of population change from stable k-selection to unstable r-selection. The average life spans and lengths of species for the most part have declined. Their growth goes on at an accelerated pace, and sexual maturity comes earlier, and their biological indices undergo a series of changes, after the stock decrease. the results show life history patterns in marine fishes of the China Sea are mostly that of r-selection, but that more and more are tending to be of the r-selection pattern with the change of the population structure. The population structure of a species or of groups within a species has a certain stability.In addition, a species exists under continuously changing conditions, so the structure resembles other features of the species in changing continually within certain limits,which represent adaptation to the changing conditions of life. It has been demonstrated that fishing has marked and various effects on populations, depending on their population dynamics. Overfishing of some species has reduced their numbers and led to a progressive fall in catches, especially for bottom fishes.
