Evaluating the resolution power of new microsatellites for species identification and stock delimitation in the Cape hakes Merluccius paradoxus and Merluccius capensis (Teleostei: Merlucciidae) [PDF]
Journal of Fish Biology, 2015 The utility of 15 new and 17 previously published microsatellite markers was evaluated for species identification and stock delimitation in the deep‐water hake Merluccius paradoxus and the shallow‐water hake Merluccius capensis. A total of 14 microsatellites were polymorphic in M. paradoxus and 10 in M. capensis.

The 2014 Operational Management Procedure for the South African Merluccius paradoxus and M. capensis resources [PDF]
, 2022 The algorithm for the 2014 Operational Management Procedure (OMP) to provide TAC recommendations for the South African Merluccius paradoxus and M. capensis resources is empirical. It calculates an increase or decrease of the TAC in relation to the level of an index combining recent CPUE and survey abundance estimates compared to a target level for that

The 2010 Operational Management Procedure for the South African Merluccius paradoxus and M. capensis Resources [PDF]
, 2010 The algorithm for the 2010 Operational Management Procedure (OMP) to provide TAC recommendations for the South African Merluccius paradoxus and M. capensis resources is empirical. It combines an increase or decrease of the TAC in relation to a) the magnitude of recent trends in CPUE and survey abundance estimates for both species and b) the relative ...

Effects of Kudoa thyrsites on Proximate Composition and Texture of Merluccius capensis and Zues capensis. [PDF]
J Fish DisABSTRACT 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. thyrsites infection on the proximate composition and texture parameters of raw fillets from two South African economically ...

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

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

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

Management and conservation implications of cryptic population substructure for two commercially exploited fishes (Merluccius spp.) in southern Africa. [PDF]
Mol Ecol ResourAbstract Genomic information can aid in the establishment of sustainable management plans for commercially exploited marine fishes, aiding in the long‐term conservation of these resources. The southern African hakes (Merluccius capensis and M. paradoxus) are commercially valuable demersal fishes with similar distribution ranges but exhibiting ...

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 EcolABSTRACT 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.

Classification of Kudoa thyrsites infected and uninfected fish using a handheld near-infrared spectrophotometer, SIMCA and PLS-DA. [PDF]
J Fish DisAbstract Kudoa thyrsites infection of marine fish typically results in myoliquefaction, which is only apparent 24 to 56 h post‐mortem. The traditional methods for the detection of K. thyrsites infected fish are time‐consuming and destructive, reducing its marketability.
