Effects of Kudoa thyrsites on Proximate Composition and Texture of Merluccius capensis and Zues capensis. [PDF]

J Fish Dis
ABSTRACT Kudoa thyrsites is a myxosporean endoparasite that infects fish, frequently resulting in myoliquefaction, impacting the texture and eating quality of fish muscle. The aim of this study was to investigate the effects of K.

When homoplasy mimics hybridization: a case study of Cape hakes (Merluccius capensis and M. paradoxus) [PDF]

PeerJ, 2016
In the marine environment, an increasing number of studies have documented introgression and hybridization using genetic markers. Hybridization appears to occur preferentially between sister-species, with the probability of introgression decreasing with ...

Comparison of growth rates of Cape hake (Merluccius capensis) and deep-water hake (Merluccius paradoxus) off Namibia [PDF]

Acta Ichthyologica et Piscatoria, 1982
Growth rates of Cape hake (Merluccius capensis) and deep-water hake (Merluccius paradoxus) off Namibia are compared tri terms of length and weight growth of both sexes of each species.

Changes in Volatile Composition of Cape Hake Fillets under Modified Atmosphere Packaging Systems during Cold Storage [PDF]

Foods, 2022
Fresh ready-to-cook fish fillets are susceptible to loss of freshness and accumulation of off-odour due to accelerated microbial spoilage. Suboptimal storage temperature and packaging conditions accelerate this process, limiting the economic potential ...

Sex-Linked Differentiation in Commercially Exploited Fishes: Rethinking Population Structure in Dynamic Marine Environments. [PDF]

Glob Chang Biol
Sex‐linked divergence, rather than geography, is the principal driver of genomic variation in the commercially important deep‐water hake (Merluccius paradoxus) located off the southern African coastline. Together with spatial differences in sex distribution and genomic diversity metrics, results suggest that males and females may differ in both range ...

Patterns of Population Genomic Variation and Evolutionary History of European Hake in the Northeastern Atlantic. [PDF]

Ecol Evol
We use for the first time whole‐genome sequencing to explore current and historical patterns of genetic diversity in European hake in the Northeastern Atlantic, focusing on the recently expanded distribution range in the North Sea. Genomic data revealed a complex scenario with three populations: North Sea, Celtic Sea and Portugal.

Nutrient Composition of Marine Fish Species From the East African Coast: Implications for Food and Nutrition Security. [PDF]

Food Sci Nutr
This study novel analytical data of 24 commonly consumed marine fish species from East Africa to assess their nutrient content and contribution to Codex nutrient reference values. Results showed that small fish species, typically eaten whole, are richer in key micronutrients compared to larger, filleted species. These findings highlight the nutritional

Optimization of a Cytochrome-P450-Monooxygenase-1A-Mediated EROD Assay in the Cape Hake Species Merluccius capensis and Merluccius paradoxus (Pisces). [PDF]

Enzyme Res, 2011
Cytochrome P450 monooxygenase 1A (CYP1A) is induced by several planar toxic compounds, for example, polychlorinated biphenyls (PCBs) and the induction of this protein is often measured in terms of CYP1A-mediated 7-ethoxyresorufin-O-deethylase (EROD) activity. This study was aimed at developing this assay in the Cape hake species Merluccius capensis and

Statistically Classified Marine Epifaunal Bioregions on the Southern Benguela Margin, South Africa. [PDF]

Ecol Evol
Marine bioregional maps underpin management and conservation planning. Data‐driven maps based on robust statistical analyses that include uncertainty are new to the marine realm as more data becomes available. The use of Regions of Common Profile models on epifauna data from the Southern Benguela margin distinguished five bioregions related to low ...

Hybridization and Introgression in Black Hakes (Merluccius polli and M. senegalensis): Evolutionary Dynamics and Conservation Implications in the Contact Zone Exploited by Multi-Species Fisheries. [PDF]

Mol Ecol
ABSTRACT Hybridization is relatively common between closely related species that share part of their distribution. Understanding its dynamics is important both for conservation purposes and to determine its role as an evolutionary mechanism. Here we have studied the case of black hakes (Merluccius polli and Merluccius senegalensis) in its contact zone.
