Growth and age differences between two male alternative reproductive tactics in the plainfin midshipman

Journal of Fish Biology, EarlyView.
Abstract The plainfin midshipman (Porichthys notatus Girard, 1854) is a toadfish with two distinct reproductive male tactics: ‘guarder males’ and ‘sneaker males’. These two tactics are anatomically, physiologically and behaviourally distinct from one another at sexual maturity, but it remained unclear whether these two male types remain fixed or ...

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters

Journal of Fish Biology, EarlyView.
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Experimentally testing the function of anal fins in the bluefin killifish, Lucania goodei

Journal of Fish Biology, EarlyView.
Abstract Anal fins are thought to affect many functions, including swimming, sperm flow and signalling. However, there are few experimental demonstrations of these functions. We manipulated male anal fins by placing a cut in the fin. We found that cut males had lower fertilization rates than uncut males.

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...
