Sexual dimorphism and allometry of external morphology in Oreochromis mossambicus [PDF]
Sexual dimorphism in growth of conventional morphometric characters was investigated in juveniles and young adults (size range: 31 to 91 mm) of Oreochromis mossambicus. A closely associated set of traits was identified that shows sexually dimorphic growth, which was positively allometric in the males.

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 ...

Abstract A type of fermented bile acid (BA) named 170HDa was produced using a biological method, and its impacts on growth performance, metabolism, and intestinal microbes in Chinese perch (Siniperca chuatsi) were investigated. Seven experimental diets were established, including treatment groups supplemented with 0.02%–0.06% 170HDa (GN1‐GN5), a ...

ABSTRACT Pesticide residues pose a significant risk to aquatic ecosystems, fauna and human health. Yet, the physiological impact on aquatic organisms, especially fish exposed to pesticide residues in the dry season, remains unexplored, and even data on chronic exposure to pesticide residue mixtures under natural environmental conditions remains scarce.

Corticosteroid biosynthesis in the interrenal cells of the teleost fish, Oreochromis mossambicus [PDF]
Applying high-performance liquid chromatography and thin-layer chromatography to separate corticosteroids, we studied the biosynthesis of steroids by the interrenal cells of the head kidneys (the adrenocortical homolog) of Oreochromis mossambicus.

ABSTRACT Aeromonas hydrophila, an omnipresent bacterium that infects a wide range of hosts, is responsible for massive mortality and significant financial losses among farm‐raised fish species. To control bacterial diseases in aquaculture systems, inappropriate antibiotic therapy is commonly practised, leading to the development of antibiotic‐resistant
