内容記述タイプ Abstract
内容記述 For the demersal fishes in the East China Sea and the Yellow Sea, interspecific relationships were studied with reference to food relations to clarify the structure of community. Research cruises were made for sampling in February-March, 1972 (wintering season of the demersal fish), August, 1972 (feeding season) and November, 1973 and 1974 (pre-wintering season). Based on the species composition, demersal fishes were classified into 4 associations : Yellow Sea association, northern East China Sea association, southern East China sea association and eastern East China Sea association. Morphological examination was made to obtain the background information on feeding activity and ability of demersal fishes. Feeding process was considered in successive 4 processes of searching, approaching, capturing and digesting. The organs that might play important role in each process were compared among fish species. Then these fish species were categorized into 5 behavioral types based on this comparative study. In consideration of those types of fish, species composition was examined in order to provide the characteristics of each association. Fishes were classified into 7 feeding groups based on food composition revealed by examination of stomach contents. Distributional patterns of the fishes within respective feeding groups indicate that most of those fishes inhabit their common area and probably have high competitive interspecific relation. The structure of fish associations was schematized considering the feeding rank order of fish species and habitats of food organisms. Variations of the food-consumer relationships were examined in relation to changes in the consumers biomass. Total amount of food consumed by the demersal fish was considered to decrease down to approximately 30% in the year of low level of demersal fish stocks compared with the year of high level. This decrease caused a relaxation on the small size prey fish and consequently their increase in number. As a result the consumption by the small size fish increased causing diminution of minute food organisms and even change of their species composition. Year-to-year catch trend was compared between commercial fishes taking into account of interspecific interactions, and evidence that changes of stock density affected interspecific interactions was not given from the examination of catch trend.
