To understand the phylogenetic position of Larimichthys polyactis within the family Sciaenidae and the phylogeny of this family, the organization of the mitochondrial genome of small yellow croaker was determined herein. The complete, 16,470 bp long, mitochondrial genome contains 37 mitochondrial genes (13 protein-coding, 2 ribosomal RNA and 22 transfer RNA genes), as well as a control region (...

The effect of cooking methods (boiling, grilling, and roasting) on the proximate and mineral composition, contaminants concentration and fatty acids profile was evaluated aiming to understand the benefits and risks associated to the consumption of the emerging farmed fish meagre (Argyrosomus regius). All the treatments led to lower moisture content. After grilling and roasting, the SFA, MUFA an...

Stock enhancement involves the augmentation of wild populations with hatchery-reared recruits. generally also includes a postrelease monitoring program which tracks stocked individuals within fishery, and this relies on having means to identify likely origin recaptured fish (e. g., physical, otolith, or genetic tags). This study reports application sibship analysis retrospectively infer mullowa...

In this work, we studied a disease outbreak that affected meagre (Argyrosomus regius) at temperature of 14–15 °C, and reached mortality rate 45% in one week. Moribund fish showed neither external nor internal signs disease. However, large number bacteria, phenotypically similar pure culture, were recovered from the liver kidney. A further phenotypic, genotypic serological characterization selec...

Many fishes rely on their auditory skills to interpret crucial information about predators and prey, and to communicate intraspecifically. Few studies, however, have examined how complex natural sounds are perceived in fishes. We investigated the representation of conspecific mating and agonistic calls in the auditory system of the Lusitanian toadfish Halobatrachus didactylus, and analysed audi...

Small seine net fish assemblages in the headwater region of the Kariega Estuary are described and compared to the catch composition in other parts of the system. The geographical headwaters of the freshwater ‘deprived’ Kariega Estuary were utilised by a range of fish species but, in contrast to the nearby freshwater ‘rich’ Great Fish Estuary, few important angling species (e.g. spotted grunter ...
