Journal of Fish Biology, EarlyView.Abstract Animal growth is a fundamental component of population dynamics, which is closely tied to mortality, fecundity, and maturation. As a result, estimating growth often serves as the basis of population assessments. In fish, analysing growth typically involves fitting a growth model to age‐at‐length data derived from counting growth rings in ...

Journal of Fish Biology, EarlyView.Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

Depth Preferences of Sturgeon In Critical Habitat [PDF]
, 2015 The depth and vertical movements of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) and shortnose sturgeon (Acispenser brevirostrum) at Bucks Ledge (river kilometer 21) in the Penobscot River were examined to investigate sturgeon depth preferences ...

Journal of Fish Biology, EarlyView.Abstract Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function.

Journal of Fish Biology, EarlyView.Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound
