The use of unmanned aircraft systems (UASs), commonly referred to as drones, has rapidly expanded across many scientific disciplines. Like other fields, fisheries research would benefit significantly from broader use of this emerging technology but has lagged behind other disciplines. Like the implementation of satellite and aircraft‐based remote sensing technology in previous decades brought a greater understanding of large‐scale spatial patterns and processes, UAS technology has the potential to put those tools in the hands of individual researchers, allowing implementation at finer spatial and temporal scales for a fraction of the cost. Our goal is to provide a “how‐to” for fisheries researchers interested in using UAS technology… Read more

In most fisheries, larger fish experience substantially higher mortality than smaller fish. Body length, life history, and behavioral traits are often correlated, such that fisheries‐induced changes in size or life history can also alter behavioral traits. However, empirical evidence regarding how size‐selective harvesting alters the evolution of behavioral traits in exploited stocks is scarce. We used experimental lines of Zebrafish Danio rerio that were exposed to positively size‐selective, negatively size‐selective, or random harvest over five generations…Read more

The increasing prevalence of hypoxia in aquatic ecosystems emphasizes the need to understand sublethal effects on organisms to anticipate potential changes in population dynamics. Carryover effects of hypoxia exposure during early life stages on lifetime survival and growth performance are rarely known, which leaves major knowledge gaps about the long‐term impacts of sublethal exposures. Geochemical signatures incorporated into fish hard parts can track lifetime hypoxia exposure…Read more
