For instance, because the two main harvested varieties of larval fish--anchovies and silversides--have very short life spans and produce eggs when just six months old, fishing may help to provide some balance in marine environments that might otherwise be quickly burdened beyond their carrying capacity.
例如主要是日本鯷和銀帶鰶的仔魚，生命週期短，六個月大就產卵，人類的捕撈反而可以平衡牠們的環境容量。
