— Somatic growth parameters are used in age-structured stock assessment models, such as those used to assess the federally managed northern anchovy ( Engraulis mordax ); therefore, incorrect estimation of growth can cause errors that affect estimates from stock assessments. To our knowledge, we completed the first comprehensive investigation to model somatic and otolith growth of the central subpopulation of northern anchovy (CSNA), which has a range from Northern California to Baja California, Mexico, by using fishery-dependent and fishery-independent data. Five growth models were fitted to length- at-age data, including 2 models that account for seasonal growth oscillations, to determine the model that best described growth. Seasonal growth oscillations were found for the CSNA

— Movements of the tiger shark ( Galeocerdo cuvier ) by life stage are largely unknown yet are necessary to determine essential fish habitat and sustainable fishery management practices. In an effort to elucidate distribution and movements of the tiger shark, we analyzed fishery-dependent and - independent tag (sample size [ n ]=10,516) and recapture ( n =762) records for sharks caught in the North Atlantic Ocean during 1963–2018. Sea-sonal distribution of the tiger shark was examined by life stage— young of the year, juveniles (immature), and adults (mature)— and distribution patterns were used to identify potential nursery habitat. Tiger sharks were caught over a wide area from the Grand Banks of Newfoundland, Canada, south to Brazil and from coastal to offshore waters and into the eastern North Atlantic Ocean. Seasonal north–south movements were observed in all life stages, and 14 immature sharks were found to have migrated from the western to the eastern North Atlantic Ocean. A broad nursery area and a potential birthing area were identified on the continental shelf between Florida and Georgia on the basis of the repeated presence of neonates in summer across years and of the recapture of multiple tagged young- of- the-year

— The Atlantic sturgeon ( Acip-enser oxyrinchus oxyrinchus ) is a anad-romous fish found along the east coast of North America and is listed under the Endangered Species Act of the United States. Decades of overfishing and habitat degradation have caused range-wide population declines, and the population status of this species in many rivers is unclear. Quantifying annual recruitment is one way to assess the status of sturgeon populations, but such assessments are few. The objective of this study was to quantify recruitment of juvenile Atlantic sturgeon in the Savannah, Ogeechee, and Satilla Rivers in Georgia. Because we used identical methods in 3 rivers simultaneously, we were able to directly compare recruitment among these populations with that of other populations observed in contemporaneous studies in other rivers. We conducted mark-recapture sampling during 2014–2017 and used Huggins closed population models to estimate annual recruitment. Because there are no historical data for comparison, we evaluated the 3 populations
