— Annual life history events, such as migration and spawning in fish, are often timed to match seasonal fluctuations in environmental conditions. Understanding phenological patterns and their drivers is needed to conserve vulnerable fish populations, particularly as climate change is disrupting seasonal transitions. In this study, we examined the phenology of spring spawning migrations of river herring, the alewife ( Alosa pseudoharengus ) and the blueback herring ( A. aestiva-lis ), in 4 rivers of Chesapeake Bay over 7 years (2013–2019). We used imaging sonar and weekly biological samples to estimate species-specific hourly fish counts in the Choptank River, Deer Creek (a tributary of Susquehanna River), Marshyhope Creek (a tributary of Nanticoke River), and the Patapsco River. Our results indicate that patterns of water temperature in spring drive spawning migrations at seasonal, daily, and hourly scales. The relationship between fish counts and other environmental factors, such as stream-flow, lunar phase, turbidity, wind stress, and tides, were annually inconsistent, and their influences on migrations may be river specific. For both species, distinct diel patterns in movement were observed. Migrations were diurnal in the Choptank River and Marshyhope Creek but nocturnal in Deer Creek and the Patapsco River. Observed interannual and inter-river variation in phenology and the influence of non-temperature factors on migrations highlight the need for long-term, multi-river monitoring of river herring in Chesapeake Bay.

— Reproductive data collected through anatomical dissection, from 48 female and 66 male tiger sharks ( Galeocerdo cuvier ) captured in the west- ern North Atlantic Ocean, were used to assess stage of maturity. The fork length (FL) of examined females and males ranged from 88 to 318 cm and from 84 to 349 cm, respectively. Median length at maturity ( L 50 ) was calculated by using binomial maturity data from dissections in addition to maturity assignments based on clasper condition examination of 320 males (46–280 cm FL) and pub- lished maturity data for 14 males (170– 313 cm FL) and 28 females (242–312 cm FL). Further, sex- specific median age at maturity ( A 50 ) was calculated by using direct age estimates and the aforemen-tioned binomial maturity data from the dissected specimens. Females reached L 50 at 261.4 cm FL and A 50 at 11.6 years. Males reached L 50 at 258.9 cm FL and A 50 at 9.5 years.
--从北大西洋西部捕获的48只雌性和66只雄性虎鲨（Galeocerdo cuvier）身上通过解剖收集的繁殖数据用于评估成熟阶段。接受检查的雌性和雄性的叉长（FL）分别为88至318厘米和84至349厘米。成熟时的中位长度（L50）是通过使用解剖的二项式成熟度数据以及基于320只雄性（46–280 cm FL）的扣环状况检查的成熟度分配以及14只雄性（170–313 cm FL）和28只雌性（242–312 cm FL）公布的成熟度数据来计算的。此外，通过使用直接年龄估计和上述解剖标本的二项式成熟度数据，计算了成熟时的性别特异性中位年龄（A 50）。雌性在261.4 cm FL时达到L50，11.6岁时达到A50。雄性在258.9厘米FL时达到L50，9.5岁时达到A50。
