Age and Growth of the Southern Blue Whiting Micromesistius Australis in the SW Atlantic*
SCI. MAR., 64 (3): 269-274 SCIENTIA MARINA 2000 Age and growth of the southern blue whiting Micromesistius australis in the SW Atlantic* MARIA CRISTINA CASSIA Instituto Nacional de Investigación y Desarrollo Pesquero, Paseo Victoria Ocampo N° 1, Mar del Plata (7600), Argentina. E-mail: mccassia@ inidep.edu.ar SUMMARY: Age and growth of southern blue whiting Micromesistius australis are studied. Sagitta otoliths from 3650 specimens were used for age determination. These were taken during research surveys and commercial catches in the South West Atlantic during 1994 and 1995. The size of fishes ranged from 17 to 60 cm total length, corresponding to ages 0 to 23 years. Females attained a greater asymptotic length (L∞ 59.74 cm) than males (L∞ 54.72 cm). Comparison of growth curves by the likelihood ratio showed that the differences among females and males were due to the asymptotic length, while the other parameters (K and t0) were not statistically different. The mean weight-at-age, mean length-at-age, and total mortali- ty (Z) were estimated. Growth parameters estimated by sex in the period 1994-95, mean size per age group, and the num- ber of individuals per age in the catches show differences with those calculated when the population was in the early stage of exploitation. A predominance of 2 to 9 year old individuals was observed in the total catches in 1994-1995, whereas in the beginning of the fisheries total catches were basically fish 15 to 19 years old. Key words: Micromesistius australis, age, growth, population-age structure, Southwest Atlantic. -
Blue Whiting — a Key Species in the Mid-Water Ecosystems of the North-Eastern Atlantic
International Council ICES CM 2002/L:28 forHeino the &Exploration Godø Theme Session L:ICES Census CM 2002/L:28of Marine of the Sea Life: Turning Concept into Reality Blue whiting — a key species in the mid-water ecosystems of the north-eastern Atlantic Mikko Heino and Olav Rune Godø Abstract. Blue whiting (Micromesistius poutassou) is a mesopelagic gadoid that is widely distributed in northeastern Atlantic from the Canary Island to Spitsbergen. It is abundant and commercially exploited in the Norwegian Seas, off Iceland, Faeroe Islands, Hebrides and Ireland, and in the Bay of Biscay. Blue whiting is a highly migratory species. During the spawning season (March-April), blue whiting concentrates to dense aggregations on the well- known spawning locations along the shelf edge west of Ireland and Hebrides and in the Rockall area. Other spawning areas also exist, but stock structure, distribution and migration of this abundant species are insufficiently known. The oceanic distribution of blue whiting westward, towards the mid-Atlantic Ridge (MAR), has not been thoroughly investigated. Scattered observations show that the species occurs along the MAR from the Azores in the south to the Reykjanes Ridge in the north. The possibility that blue whiting is a key species in the mi-water community of the MAR should not be dismissed. Where present, blue whiting is often highly abundant, and plays an important role in the pelagic ecosystems, both as a consumer of zooplankton and small mesopelagics, and as a prey for larger fish and cetaceans. Is there a ‘stock’ of blue whiting over the MAR? If yes, is this stock separate from the stock(s) in the northeastern Atlantic? Institute of Marine Research in Bergen has proposed a component project of MAR-ECO that combines routine monitoring information with observations from the MAR-ECO surveys to evaluate the significance of blue whiting in the pelagic ecosystem of the MAR. -

(2015) and as updated to 2017 by Dunstan et al. (2020). Much of the below materials and descriptions focus heavily on earlier periods, for which fewer contiguous data time series or formal sources are available, compared to the more recent years. We derived time series estimates for all sources of unreported marine fisheries catches (landed and discarded) and combined these with the landings data reported by the National Marine Fisheries Service (NOAA-NMFS) to the FAO on behalf of the USA. Thus, we follow the general ‘catch reconstruction’ methodology and process of Zeller et al. (2016). We define ‘reported catch’ as that catch that is included in official national and hence international FAO data. -

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). -
