Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

open access: yesJournal of Fish Biology, EarlyView.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Lactiplantibacillus plantarum I Induces Gonad Growth in the Queen Scallop Aequipecten opercularis (Linnaeus, 1758) under Conditions of Climate Change

open access: yesFishes
Climate change has presented a serious problem in recent times, which is why a new approach is being sought in terms of aquacultural food quality. In this study, the influence of temperature increase (by 2 °C) and pH decrease (by 0.2) was investigated on

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...

Biological characteristics and mortality of western butterfish (Pentapodus vitta), an abundant bycatch species of prawn trawling and recreational fishing in a large subtropical embayment [PDF]

open access: yes, 2006
The western butterfish (Pentapodus vitta) is numerous in the bycatch of prawn trawling and recreational fishing in Shark Bay, Western Australia. We have thus determined crucial aspects of its biological characteristics and the potential impact of fishing

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.

Efficiency of letrozole loaded PLGA nanoparticles on sex reversal of Poecilia reticulata (Peters, 1859) [PDF]

open access: yes, 2015
Males of Poecilia reticulata showed extreme diversity in color, particularly of their fins, while the females lack the bright colors and are largely whitish. Such extreme variability of color and finnage lead to demand of males in the markets. The aim of

Reproductive plasticity and environmental tolerance of invasive African catfish (Clarias gariepinus) in a tropical Brazilian river

open access: yesJournal of Fish Biology, EarlyView.
Abstract Invasive alien species (IAS) pose a significant threat to biodiversity, particularly when endowed with high ecological and reproductive plasticity. The African catfish, Clarias gariepinus, is one such species, widely recognized for its ability to colonize and establish in diverse tropical ecosystems.
