| 概要 |
The concept of environmental capacity of oyster culture in the northern part of Hiroshima Bay is proposed using a numerical ecosystem model which contains the cultured oyster. The relation between the... chlorophyll-a concentration in the upper layer and mortality rate of the cultured oyster was approximated with the TANH function, and the formula about the biochemical process of oyster was built. As the result of numerical ecosystem model calculation, we suggest that the concept of environmental capacity of oyster culture fishery in the northern part of Hiroshima Bay is defined by total phosphorus (TP) load from Ohta River maximizing the standing stock of cultured oyster.続きを見る
