Three hypotheses about poor recruitment and collapse of Striped Bass Morone saxatilis in Chesapeake Bay during the 1970s and 1980s (excessive larval mortality related to water quality, recruitment overfishing, or a combination) emerged from intense investigations during the mid-1980s into the early 1990s. Stock collapse during the 1970s and 1980s and recovery in 1995 were largely attributed to fishing mortality and this premise largely drives management. Stock and larval habitat assessments were not available before the early 1980s and habitat assessments were discontinued after recovery. I used egg and juvenile index time-series that extended back to 1955 to test these three hypotheses about changes in productivity.

随着时间的推移，观点会随之而来：长期卵和幼鱼指数对切萨皮克湾条纹鲈生产力有何影响？

1970 年代和 1980 年代切萨皮克湾条纹鲈的补充不良和死亡的三个假设（幼体死亡率过高与水质、补充过度捕捞或两者兼而有之）是从 20 世纪 80 年代中期到 1990 年代初的深入调查中得出的。1970 年代和 1980 年代种群数量的崩溃以及 1995 年的恢复主要归因于捕捞死亡率，这一前提在很大程度上推动了管理。20 世纪 80 年代初之前，尚无种群和幼虫栖息地评估，恢复后栖息地评估也停止了。我使用可追溯到 1955 年的鸡蛋和幼鱼指数时间序列来检验这三个关于生产率变化的假设。
