What makes a habitat a home for juvenile fish? Assessing the importance of estuary habitat characteristics for growth and survival of European Sea bas

鱼类种群丰度的大部分变化是在早期生命阶段产生的，当时海水鱼幼鱼每天的死亡率高达20%--死亡率的微小变化可能会导致产卵种群生物量的巨大变化。此外，这些微小的变化可以产生特殊的年级，这可能会在几年内主导商业收获的库存。因此，更好地了解支撑具有商业重要性的幼鱼生长和存活的因素，对于改进种群管理至关重要。

Most variance in fish stock abundance is generated during early life stages, when juvenile marine fish can experience mortality rates of up to 20% per day - small shifts in mortality rates can generate large changes in spawning stock biomass. In addition these small changes can generate exceptional year-classes which can dominate commercially harvested stocks for several years. Consequently, a better understanding of the factors underpinning the growth and survival of juvenile fishes of commercial importance are critical for improved management of stocks.
