Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

Vertical Habitat Use by Japanese Jack Mackerel Trachurus japonicus Inferred From a Biologging Study in Tokyo Bay

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures

open access: yesJournal of Fish Biology, EarlyView.
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

open access: yesJournal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Bull trout (Salvelinus confluentus) exhibit binge‐feeding and digestive flexibility during seasonal resource pulses associated with salmon migrations

open access: yesJournal of Fish Biology, EarlyView.
Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

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

open access: yesJournal 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 ...

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

open access: yesJournal 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.

Phenotypic divergence may facilitate co‐occurrence in Acanthopagrus species (Family: Sparidae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding why closely related species co‐occur is one fundamental question in ecology. The seabream genus Acanthopagrus Peters, 1855 (Sparidae) is broadly distributed across the Indo‐Pacific, with four species, A. arabicus and A. sheim (yellowfin group), and A. bifasciatus and A.
