English term or phrase:sustainable yield
Definition from John Wiley & Sons: The amount of a naturally self-reproducing community, such as trees or fish, that can be harvested without diminishing the ability of the community to sustain itself.
Marine conservation requires a new ecosystem-based concept for fisheries management that looks beyond sustainable yield for individual fish species American Scientist
A judicious use of thinning might increase the level of the sustainable yield by prolonging the length of time in which large trees are rapidly accruing merchantable volume. Yale University School of Forestry
Sustainable yield is difficult to obtain definitively,
because agricultural production is affected by climate,
soil quality, and management practices in an interwoven
Definition from own experience or research: sustainableで一般的には維持できる事を意味し、yieldで産出高を意味します。この場合はその種の水産物の個体群数が採取してもその後の個体群数の一定の維持と生態学的に悪影響を起こさないというのが前提になっています。そのため、漁獲量の制限をもってその種の水産物が絶滅しなく、かつ定期的に採取できるようにしている。
In population ecology and economics, maximum sustainable yield or MSY is, theoretically, the largest yield/catch that can be taken from a species' stock over an indefinite period. Under the assumption of logistic growth, the MSY will be exactly at half the carrying capacity of a species, as this is the stage at when population growth is highest. The maximum sustainable yield is usually higher than the optimum sustainable yield. - wikipedia
