Exploring Long-Term Patterns: Black Bass Tournament Fishery And Population Trends In West Virginia's Navigable Rivers, Alex J. Benecke

Graduate Theses, Dissertations, and Problem Reports (ETD)

Black bass Micropterus spp. are popular sport fish in West Virginia’s navigable rivers. In recent years, anglers have expressed concerns about a potential decline in fishery quality. To investigate these claims, we evaluated whether fishery quality has declined compared to earlier periods and whether population trends correspond to angler catch rates. Specifically, we aimed to (1) examine changes in species catch over time and during key periods, such as tournament and spawning seasons; (2) describe the distribution of black bass species across pools and habitat types; and (3) assess the outcomes of previous stocking efforts. To address these objectives, we …

Shero, Jennifer M. Burns, Eileen E. Hofmann, Sharon E. Stammerjohn, Elliott L. Hazen, David G. Ainley, Daniel P. Costa

CCPO Publications

Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour. Using biologgers, we tagged 62 post-moult Weddell seals in McMurdo Sound and vicinity between 2010 and 2012. Generalized additive mixed models were used to (i) explain and predict the probability of seal presence and foraging behaviour from eight environmental variables, and (ii) examine foraging behaviour in relation to dive metrics. Foraging probability was highest in winter and lowest in summer, and foraging occurred mostly in …
