Can changes in structure and production in higher trophic level in the Seto Inland Sea be explained by changes in the food web structure?


Aquabiology (Tokyo). June; 273: 253-258: 158
Can changes in structure and production in higher trophic level in the Seto Inland Sea be explained by changes in the food web structure?
The decrease of fish catch and increase of jellyfish have been observed in the Seto Inland Sea, Japan. In this study, causes that may have induced the changes in structure of the higher trophic level was investigated theoretically under the hypothesis that the changes of top-down/ bottom-up controls may have changed the food web structure. The present simple model explained that the bottom-up force induced by the reduction of dissolved inorganic phosphorus led the decrease of sardine stock and the Japanese anchovy/jellyfish group as well. It also understood that the top-down force represented by over-fishing of sardine led the same scenario decreasing not only the sardine stock but also the Japanese anchovy/jellyfish group.
