Management and conservation implications of cryptic population substructure for two commercially exploited fishes (Merluccius spp.) in southern Africa. [PDF]

Mol Ecol Resour
Abstract 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 ...

Occurrence of mislabelling in prepared fishery products in Southern Italy [PDF]

Italian Journal of Food Safety, 2015
Fish authentication is a major concern not only for the prevention of commercial fraud, but also for the assessment of safety risks deriving from the undeclared introduction of potentially dangerous toxic or allergenic substances or environmentally ...

Do You Study What You Eat? Comparing South African Aquatic Food Production Statistics With Research

Aquaculture, Fish and Fisheries
In many countries, foods from aquatic sources provide an important source of protein and key micronutrients. However, aquatic food systems can be impacted by hazards, which drive inefficiencies. Such inefficiencies have consequences for the environmental,

Occurrence of larval nematode Anisakis simplex, larval cestode Hepatoxylon trichiuri and parasitic copepod Parabrachiella australis in juvenile Merluccius capensis off Namibia [PDF]

Acta Ichthyologica et Piscatoria, 1980
The author examined 2145 juvenile individuals of cape hake, Merluccius capensis Castelnau, 1861 caught off Namibia. The presence of larval Anisakis simplex (Rud., 1809), larval Hepatoxylon trichiuri Holten, 1802 as well as Parabrachiella australis Wilson,

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]

EFSA J
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Classification of Kudoa thyrsites infected and uninfected fish using a handheld near-infrared spectrophotometer, SIMCA and PLS-DA. [PDF]

J Fish Dis
Abstract 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.

Stock-environment recruitment analysis for Namibian Cape hake Merluccius capensis [PDF]

African Journal of Marine Science, 2013
The factors modulating recruitment success of Cape hake Merluccius capensis  in Namibian waters are still unresolved. In this study, we used generalised additive models, regression tree analysis and the conventional Ricker model to examine the effect of environmental indices and spawning stock biomass (SSB) on hake recruitment success for the period ...

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

Variations of fishes of genus Merluccius in Atlantic Ocean and Mediterranean Sea [PDF]

Acta Ichthyologica et Piscatoria, 1973
In this study, the association between morphometric, meristic and osteological characters was used comparatively. Therefore, as a result of this work, five subspecies were determined along the coasts of NE-Atlantic, Mauritania, SW- and S-Africa, and ...
