Pike (Esox lucius) stock management in designated brown trout (Salmo trutta) fisheries: Anglers’ preferences. ESRI WP563, May 2017 [PDF]

, 2017
This paper examines anglers' preferences for active stock management of pike populations within designated wild brown trout fisheries in Ireland. While the policy of pike control has a long history, it is not without controversy and conflict.

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Review of the southern African slender stonebashers, genus Heteromormyrus Steindachner 1866 (Teleostei: Mormyridae), with description of six new species

Journal of Fish Biology, EarlyView.
Abstract Recent molecular studies have advanced our knowledge of the taxonomic diversity and generic placement of the slender stonebashers, previously placed in the genus Hippopotamyrus, in southern Africa. These fishes were recently transferred to the genus Heteromormyrus whose range encompasses the Kwanza, Kunene, Okavango, Zambezi, Pungwe and Buzi ...

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

Journal 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 ...

Relationship between cortisol and glucose as physiological stress indicators during growth season in juvenile Siberian sturgeon Acipenser baerii

Journal of Fisheries, 2020
The relationship between cortisol and glucose was studied in two-year old farmed Siberian sturgeon Acipenser baerii with a body weight of 340±30 g (mean ± SD) and total length of 45±1 cm from August to November 2017.

A new species of Peckoltia (Siluriformes, Loricariidae) from the rapids of the Rio Tocantins‐Araguaia basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Here, we describe a new species of Peckoltia (Loricariidae; Hypostominae) from the rapids of the Rio Tocantins‐Araguaia basin, previously identified as Peckoltia vittata, using an integrative taxonomy approach. The new species is distinguished from congeners by ventral region presenting diffuse stripes on surface, not presenting spots or ...

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

Journal 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 ...
