An Analysis of Methods for Quantifying Crappie Recruitment Variability

TL;DR: In this article, the authors used catch-at-age data from 122 populations of crappies Pomoxis spp from across the midwestern and southeastern United States to compare two methods for defining recruitment variability: (1) the recruitment coefficient of determination (RCD), calculated from the weighted linear regression of loge(catch at age + 1) on age, and (2) recruitment variability index (RVI) Ranked values of the RCD and RVI were significantly correlated, which suggests that both indices measured variability in catch at age data in a similar manner.

Evidence of Declining Recruitment of Atlantic Sturgeon in the Hudson River

TL;DR: The Hudson River supports one of the largest remaining populations of Atlantic sturgeon Acipenser oxyrinchus; however, recent evidence of major declines in recruitment during the past decade suggests that the population may be in jeopardy.

Validated age and growth estimates for Carcharhinus obscurus in the northwestern Atlantic Ocean, with pre- and post management growth comparisons

TL;DR: Age and growth estimates for the dusky shark, Carcharhinus obscurus, were derived from vertebral centra collected in the northwestern Atlantic Ocean and support the traditional interpretation of annual band pairs up to approximately 11 years of age.
