Environmental conditions, diel period, and fish size influence the horizontal and vertical movements of red snapper

Abstract Most demersal fishes are difficult to observe and track due to methodological and analytical constraints. We used an acoustic positioning system to elucidate the horizontal and vertical movements of 44 red snapper (Lutjanus campechanus) off North Carolina, USA, in 2019. Mean movement rate a...
