New age-determination method based on fast growth rate of Cape hake Merluccius capensis in Namibia [PDF]
African Journal of Marine Science, 2019 Namibia’s most important commercial fisheries resource, the shallow-water Cape hake Merluccius capensis, is currently assessed using statistical catch-at-age analysis.

Data on hake (Merluccius capensis and Merluccius paradoxus) abundance along the Namibian coast showed both species to have strongly aggregated spatial distributions. In addition, average fish size increased with depth, suggesting that the formation of hake aggregation is based on size-dependent shoaling behaviour.

Serial spawning and batch fecundity of Merluccius capensis and M. Paradoxus
South African Journal of Marine Science, 1999Histological analysis of the ovaries and the presence of multiple modes in oocyte size frequency distribution of Cape hake Merluccius capensis and M. paradoxus indicates that they are serial spawners. Batch fecundity,calculated by means of the “hydrated oocyte method”, was positively correlated to ovary-free fish mass and total fish length.

General linear models (GLMs) were used to determine the relative importance of interspecific, ontogenetic and spatial effects in explaining variability in stable isotope ratios of nitrogen (δ15N) and carbon (δ13C) of the co‐occurring Cape hakes Merluccius capensis and Merluccius paradoxus off South Africa.

Vacuum packed hake muscle subjected to 400 MPa (three 5-min cycles) at 7 °C proved to be more stable at chilled temperatures (2-3 °C), and sensorially acceptable, until 43 days of storage in comparison with the nine days for the non-pressurized hake. The lot pressurized at 400 MPa had the appearance of cooked muscle.

Abstract There has been great interest in the identification of Cape hakes, Merluccius capensisand Merluccius paradoxus, by non-morphological methods. The information provided by a ribosomal DNA-based method will allow investigators to precisely identify the species of Cape hake in commercial samples.

Feeding selectivity of juvenile Cape hakeMerluccius capensisin the southern Benguela
South African Journal of Marine Science, 1993Prey selectivity and feeding behaviour of juvenile shallow-water Cape hake Merluccius capensis are investigated on the basis of material collected at two sites of contrasting feeding regimes in coastal waters off the South African west coast. Hake collected from a site abundant in zooplankton fed preferentially on relatively large crustaceans ...

Changes in Catchability in a Bottom-Trawl Fishery for Cape Hake (Merluccius capensis)
Canadian Journal of Fisheries and Aquatic Sciences, 1991Management of the Cape hake (Merluccius capensis) stock off the coasts of Angola and Namibia has been based on surplus production modeling, which incorporates an assumption of constant catchability. Results of least-squares catch-at-age analysis and virtual population analysis were used to estimate catchability from 1968 to 1986.

The diet of Cape hakeMerluccius capensison the south coast of South Africa
South African Journal of Marine Science, 1995In stomach contents of Cape hake Merluccius capensis collected during demersal research surveys (1989–1994) on the south coast of South Africa, fish remains accounted for 92% by mass, crustaceans for 5% and cephalopods for 3%. Fish prey consisted of 51% pelagic, mainly anchovy (33%), round herring (11%) and pilchard, 24% horse mackerel and 17% demersal
