Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

open access: yesJournal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Slow growth rates of common carp Cyprinus carpio in English catch‐and‐release fisheries are related to high stock densities

open access: yesJournal of Fish Biology, EarlyView.
Abstract Hatchery‐reared, domesticated strains of common carp Cyprinus carpio (‘carp’) are regularly used to enhance angler catch rates in many catch‐and‐release (C&R) lentic fisheries. These carp are usually selected for specific traits (e.g. stress resilience, high probability of angling capture) and are often stocked at relatively small sizes into ...

Target-specific feeding strategies in carp-tilapia polyculture ponds: Effects of feed type and carp size

open access: yesAquaculture Reports
In polyculture ponds, feeding strategies can affect the species-specific intake and utilisation of both supplementary feed and natural food, thereby influencing overall pond performance.

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.

Perspectives from agriculture: advances in livestock breeding - implications for aquaculture genetics [PDF]

open access: yes, 2006
In this paper we present livestock breeding developments that could be taken into consideration in the genetic improvement of farmed aquaculture species, especially in freshwater fish.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

open access: yesJournal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...
