Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Effect of hybridisation on fecundity of Oreochromis karongae (Trewavas 1941)

Egyptian Journal of Aquatic Research, 2017
Effect of hybridisation of female Oreochromis karongae and male O. shiranus on fecundity of O. karongae, was investigated at Bunda, Lilongwe, Malawi. Number of eggs, weight (mg) and diameter of individual egg (mm) and relative fecundity were assessed ...

Molecular systematics of three tilapiine genera Tilapia, Sarotherodon and Oreochromis using allozyme data

, 1991
Allozyme data from 44 different loci were collected for 15 species from three genera in the tribe Tilapüni. Dendrograms constructed by using both genetic distance and binary coded presence or absence of alleles show that the substrate spawning ...

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

‘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 ...
