Author:McGregor, Emily SkyeDate:2015An Ecosystem Approach to Fisheries management (EAF) offers a holistic approach for sustainable fisheries management by extending the traditional target resources-orientated management (TROM) to include wider social-ecological dimensions of ...Read more
Author:Uzonnah, Nwamaka Mary-ImmaculataDate:2017An understanding of the population structure of commercially exploited species is essential for effective fisheries management. Fish stocks are typically identified based on the observation of differences in genetic and/or phenotypic ...Read more
Author:Twatwa, Nandipha MDate:2002The spawmng habitats of anchovy (Engraulis capensis) and sardine (Sardinops sagax) in the southern Benguela upwelling ecosystem were characterized by comparing the data on abundance and distribution of eggs of the two species with environmental ...Read more
Author:Tjizoo, Mbeurora BeauDate:2008Spawning habitats of sardine and anchovy in eastern boundary systems are characterized in an attempt to understand the fluctuations observed in their abundance. These species have developed mechanisms that enable them to survive in these ...Read more
Author:Mketsu, Qayiso KDate:2008Stomach contents of sardine (Sardinops sagax), anchovy (Engraulis encrasicolus), west coast redeye (Etrameus whiteheadi) and east coast redeye (E. teres) were collected from presumed mixed shoals off South Africa's east coast. The stomach ...Read more
Author:Sono, SandisiweDate:2008The accuracy of using CUFES (continuous underway fish egg sampler) as an alternative method to vertical bongo nets for sampling zooplankton abundance and distribution is assessed. Analysis is based on 14 taxonomic groups representing a wide ...Read more
Author:Schlegel, Robert WilliamDate:2014Satellite data have high spatial/ temporal resolution, extensive coverage and are easily accessible, making them a common part of many studies on the oceans. One such important study to use satellite data found a relationship between the ...Read more
Author:Dopolo, Mbulelo TomieDate:2003Three fish species, anchovy Engraulis encrasicolus, sardine Sardinops sagax and round herring Etrumeus whiteheadi, co-exist over the western Agulhas Bank (W AB) in the southern Benguela upwelling ecosystem. To date, data on high-resolution ...Read more
Author:Duthie, Tarryn-LeeDate:2007Spatial variability in egg volume was investigated for anchovy, sardine and round herring in the southern Benguela in 1998, 2000 and 200 l. The relationship between sea surface temperature (SST) and egg volume was determined and the parental ...Read more
Author:Astor, NicoleDate:2014A knowledge-based tool was developed to assess the efficacy of the ecosystem approach to fisheries in the South African anchovy fishery. South Africa has agreed to implement an ecosystem approach to fisheries (EAF) management. The EAF management ...Read more
Author:Miller, David Charles MoorcroftDate:2006Hypotheses regarding the spawning strategy and recruitment of sardine (Sardinops sagax) in the southern Benguela ecosystem are tested using an individual-based Lagrangian particle tracking model linked with a 3-D hydrodynamic model of the ...Read more
Author:Weston, Mark JonathanDate:2018Parasitism is accepted as being an essential driver in the organization of biological communities. However, although there are estimated to be more parasitic than free-living organisms, parasites have been largely neglected from ecological ...Read more
Author:Mapukata, TembelaDate:2002Laboratory studies were conducted on juvenile horse mackerel to examine feeding selectivity and rates of zooplankton consumption of two size classes of fish. Fish were fed a variety of natural zooplankton assemblages and sequential subsampling ...Read more
Author:Idris, IzwandyDate:2010Branchial sieves of southern African sardine (Sardinops sagax ocellatus) were collected from three geographical regions along the southern African coast: Namibia, the south coast and the west coast of South Africa. Sardine from Namibia ...Read more
Author:Wessels, GreaDate:2009Meristic counts and morphometric measurements were made on previously frozen sardine Sardinops sagax to determine whether there is a difference in the shape of sardine from different areas around southern Africa. Because freezing influences ...Read more
Author:McGrath, AliceDate:2018The transport and retention of sardine (Sardinops sagax) eggs on the west and south coasts of South Africa were investigated using a Lagrangrian, particle tracking, individual-based model (IBM), coupled with two 3-D hydrodynamic Regional Ocean ...Read more
Author:Hampton, ShannonDate:2014Three abundant small pelagic fish species co-occur in the Benguela upwelling ecosystem off southern Africa: sardine (Sardinops sagax), anchovy (Engraulis encrasicolus) and round herring (Etrumeus whiteheadi). It is hypothesised that populations ...Read more
Author:Ssempa, Nurudean NormanDate:2013A total of 553 male southern African sardine Sardinops sagaxcollected between 2010 and 2012 from around southern Africa, including from the northern Benguela off Namibia and from the South African west, south and east coasts, were examined ...Read more
Author:Le Roux, Jessica LouiseDate:2013A survey of parasites infecting Cape horse mackerel, Trachurus capensis Castelnau, 1861, from both the southern and northern Benguela ecosystems was conducted to test the hypothesis of discrete stocks in each subsystem. One hundred and twenty ...Read more
