Scales small, 132 to 149 along lateral line. Number of vertebrae 23 to 26 (precaudal) + 24 to 28 (caudal) = 49 to 53 (total). Colour: silvery, somewhat brownish on back, whitish on belly. Geographical Distribution FAO Fisheries and Aquaculture Department Launch the Aquatic Species Distribution map viewer Southern and southwestern Africa, from Baie Farte (12.5°S), over the Agulhas Bank in the south, to Natal (28°S). Also found on the Valdivia Bank (26°18'S, 6°20'E). Habitat and Biology Lives close to the bottomon the continental shelf and upper slope (550 m).Females grow faster than males, with sexual maturity attained at 45 to 60 cm in the Cape region. Spawning appears to be mainly from October to December (mid-spring to early summer). This hake migrates seasonally southward in the southern spring, and northward in autumn.The young (to about 64 cm) feed mainly on small crustaceans and small deep-sea fishes such as lantern fishes, whereas larger individuals feed chiefly on small hakes and jack mackerel. Size Maximum length 120 cm; commonly 40 to 60 cm. Interest to Fisheries An important foodfish. Most of the catches for this species are reported to FAO combined with those of Merluccius paradoxus, a similar species which lives in the same area of Merluccius capensis but usually at greater depths. For 1995, 278,257 t were reported to FAO for the two species combined (mainly by South Africa and Namibia) and 28 t by Angola only for M. capensis (M. paradoxus is not present in Angola). Until 1978, this species, together with M. paradoxus yielded the largest hake catches in the world (i.e. 1,122,000 t in 1972). Caught mainly with bottom trawls (otter trawls) at 550 m depth and processed into fish blocks. Most common fishing techniques are "demersal bottom trawling" and "Hake trawling". The total catch reported for this species to FAO for 1999 was 2 060 t. The countries with the largest catches were Angola (2 060 t).

  • Merluccius Capensis) Across the Western Coast Of
    SEASONAL TRANSBOUNDARY MOVEMENT OF CAPE HAKE (MERLUCCIUS CAPENSIS) ACROSS THE WESTERN COAST OF SOUTHERN AFRICA A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN BIODIVERSITY MANAGEMENT OF THE UNIVERSITY OF NAMIBIA BY VERONICA KALEINASHO KAPULA 201075822 April 2018 MAIN SUPERVISOR: DR. H.ON. Ndjaula (University of Namibia) CO-SUPERVISOR: DR. R. Henriques (Stellenbosch University) ABSTRACT This study was conducted to investigate the patterns of genetic differentiation of Cape hake (Merluccius capensis) across Southern Africa, using eight nuclear microsatellite markers to understand the seasonal movements of the two previously identified stocks. The aim of the project was to assess the position of the genetic break in two different temporal sampling events: summer months (February – March) and winter months (June – August) and to investigate the level of genetic diversity for 2017. Individual fishes were chosen randomly from a pool of samples, covering the distribution from the Cunene River Mouth, in northern Namibia, to Cape Town in South Africa. Six main sampling sites were chosen based on latitude and their relative position regarding known oceanographic breaks: Northern Namibia, Central Namibia, Southern Namibia, Orange River, Central West Coast and Southern West Coast. Total genomic DNA was extracted using a standard chlorophorm: isopropanol method of Backeljau, Dewachter &Winnepenninckx (1993). The Polymerase Chain Reaction (PCR) amplification of a fragment of the Control Region (CR) of the mtDNA was done for species validation. A total of 533 individuals were screened for genetic variation at eight nuclear microsatellite loci. The results shows an overall Fixation index (FST ) = 0.160 for summer and FST = 0.112 for winter, which were statistically significant different from zero (p<0.05).

  • Evolutionary Divergence Between Sympatric Species of Southern African Hakes, Merluccius Capensis and M
    Heredity 61(1988)13—20 The Genetical Society of Great Britain Received 17 September 1987 Evolutionary divergence between sympatric species of southern African Hakes, Merluccius capensis and M. paradoxus. I. Electrophoretic analysis of proteins W. Stewart Grant,* Department of Microbiology, University of Cape Inga I. Becker and Town, Rondebosch 7700, South Africa. t Sea Fisheries Research Institute, Private Bag X2, Rob W. Lesliet Rogge Bay 8012, South Africa. We estimated the amount of genetic divergence between two morphologically similar species of southern African hake, Merluccius capensis and M. paradoxus, with the electrophoretic analysis of proteins encoded by 31 loci. Nei's genetic distance between these taxa was 0•583 (±0.160) and is typical of evolutionary divergence between well differentiated congeneric species. We found no evidence of hybrid individuals. The mean heterozygosity over 13 samples of M. capensis was 0055 and over 10 samples of M. paradoxus was 0•067. The present sympatric distributions of these fish are most likely the result of secondary contact after speciation in allopatry or the result of repeated dispersals of ancestral populations of other Atlantic Ocean hakes to southern Africa, rather than the result of sympatric speciation. There were significant excesses of rare alleles in both species as compared with that expected for neutral alleles in species at drift-mutation equilibrium. Average heterozygosities, however, were not appreciably reduced in comparison with other marine fish. Using genetic distance and the assumptions of the molecular clock, we estimate that the lineages leading to these species diverged from one another between 7 and 13 million years ago.

  • Utilisation of Hake Rest Raw Material in Namibia. United Nations University Fisheries Training Programme, Iceland
    unuftp.is Final Project 2018 ASSESSMENT OF THE “FULL” UTILIZATION OF HAKE REST RAW MATERIAL IN NAMIBIA Etuna T.K.T Haimbili Ministry of Fisheries and Marine Resources Private Bag 13355, Brendan Simbwaye Square, Block C Corner of Dr. Kenneth D Kaunda & Goethe Streets, Windhoek, Namibia [email protected] Supervisor Dr. Birgir Thor Runolfsson Department of Economics University of Iceland [email protected] ABSTRACT The Namibian 5th National Development Plan goal for the fisheries sector is to increase value addition and maximise economic returns from marine resources. With limited fish stocks, it is important to maximise utilisation of the catch, by considering processing rest raw material. Possibilities for utilisation of rest raw material are arising in various countries (Kim, 2014). This study is therefore aimed at identifying the potential possibilities of the underutilised and wasted raw material and describing management tools that support economic gains from RRM. An analysis was done to identify the influencing factors of the Icelandic cod fishery’s full utilisation and it was compared to that of the Namibian hake. Data was gathered on the current level of utilisation of the hake industry in Namibia and Icelandic cod for the purpose of comparative analysis. The research revealed that the Namibian hake fishing industry utilises about 70% of the whole hake, and that the hake fishery lacks some influencing factors which seem to support the full utilisation mechanism, such as fisheries management system, technology, clusters, research and development. The study, therefore, suggests that there is a need to get a “fuller” picture of current utilisation in the Namibian hake fishery.

Although pen- guins are regularly captured in fishing gear, the threat to penguins as a group has not yet been assessed. We reviewed both published and grey literature to identify the fishing gear types that penguins are most frequently recorded in, the most impacted species and, for these susceptible species, the relative importance of bycatch compared to other threats. While quantitative esti- mates of overall bycatch levels are difficult to obtain, this review highlights that, of the world’s 18 species of penguins, 14 have been recorded as bycatch in fishing gear and that gillnets, and to a lesser extent trawls, are the gear types that pose the greatest threats to penguins.

  • Phylogenetic Prospecting for Cryptic Species of the Genus Merluccius
    www.nature.com/scientificreports OPEN Phylogenetic prospecting for cryptic species of the genus Merluccius (Actinopterygii: Merlucciidae) Montse Pérez1, María Fernández‑Míguez1,2, Jesús Matallanas3, Domingo Lloris4 & Pablo Presa2* Hakes of the genus Merluccius include 11 valid species as well a number of rare morphotypes suspected to be “cryptic species”. Concatenated nucDNA ITS1‑rDNA and mtDNA cyt b sequences plus nested ITS1Nes sequences allowed to ascribe 14 specimens of nine rare morphotypes from the South Pacifc and the South Atlantic to the phylogenetic backbone of this genus. Bayesian analyses pointed to M. bilinearis and M. albidus as the oldest species of the genus and the New World cluster, respectively. The phylogenetic status of M. angustimanus from the upper Gulf of California suggests its hybrid origin between M. gayi and M. productus from about 0.25 MYA, although an ever since confnement of a subset of those species cannot be ruled out. The molecular phylodiagnostic test suggests a common origin of all rare morphotypes and the absence of cryptic hake species in the Southern Cone. The molecular background of the morphotypes distributed between the Western Pacifc South of New Zealand and the western Atlantic South of Argentina is compatible with their hybrid origin between M. gayi and both, M. australis or M. hubbsi, respectively. Te genus Merluccius comprises 11 valid species that occur on most temperate and tropical continental shelves except the Asian shores of the Pacifc Ocean1. Hakes show an anti-tropical distribution in the Atlantic Ocean and the Eastern Pacifc and a latitudinal bathymetric overlap between isotherms 7 °C and 23 °C2–4.
