From occasional records to regular presence: Increasing occurrence of the bastard grunt Pomadasys incisus in the French Ligurian Sea (northwestern Mediterranean)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The bastard grunt Pomadasys incisus (Bowdich, 1825), an Atlantic teleost, has recently been recorded at multiple sites along the French Ligurian Sea. Three juveniles were captured in Villepey Lagoon, while several groups of sub‐adult and adult individuals were observed at Cagnes‐sur‐Mer and Monaco between 2020 and 2024.

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

open access: yesJournal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Temperature effects from hydropeaking impair egg and larval development in Danube salmon Hucho hucho and brown trout Salmo trutta

open access: yesJournal of Fish Biology, EarlyView.
Abstract Hydropeaking is considered an important stressor for salmonids and other species in rivers affected by hydropower. In this study, we investigated the in situ effects of hydropeaking on the survival of eggs and larvae of fall spawning brown trout as well as spring spawning Danube salmon.

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

open access: yesJournal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Resource use by threatened, native Bull Trout (Salvelinus confluentus) in the presence of two non‐native salmonids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Introduction of non‐native species contributes to the global decline of freshwater fishes by disrupting the diet and resources of native species through competition. Despite the potential for non‐native trout (Family: Salmonidae) to compete with native trout, non‐native trout species have been widely introduced worldwide to support ...
