Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

open access: yesJournal of Fish Biology, EarlyView.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Cryptobenthic reef fishes may not be safe from invasive lionfish (Pterois spp. Oken, 1817)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Lionfish (Pterois spp.) are hypothesized to negatively influence cryptobenthic reef fish assemblages through predation. We evaluated these potential effects on Caribbean reefs in Costa Rica and tropical reefs in Brazil. Brazil provided a reference condition for cryptobenthic assemblages prior to lionfish invasion, while the Costa Rica sites ...

Ontogenetic and spatial variation in the trophic ecology of the shortfin mako shark (Isurus oxyrinchus) in temperate eastern Australia

open access: yesJournal of Fish Biology, EarlyView.
Abstract The shortfin mako (Isurus oxyrinchus) is a fast‐swimming pelagic shark of global ecological and socioeconomic importance, yet it is relatively understudied in temperate eastern Australian waters. This study investigated the trophic ecology of mako sharks using stable isotope analysis (SIA) of nitrogen (δ15N), carbon (δ13C) and sulphur (δ34S ...

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

open access: yesJournal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...
