Simulations of Fishing Effects on the Southern Benguela Fish Community Using an Individual-Based Model: Learning from a Comparison with Ecosim
Ecosystem Approaches to Fisheries in the Southern Benguela Afr. J. mar. Sci. 26: 95–114 2004 95 SIMULATIONS OF FISHING EFFECTS ON THE SOUTHERN BENGUELA FISH COMMUNITY USING AN INDIVIDUAL-BASED MODEL: LEARNING FROM A COMPARISON WITH ECOSIM Y-J. SHIN*, L. J. SHANNON† and P. M. CURY* By applying an individual-based model (OSMOSE) to the southern Benguela ecosystem, a multispecies analysis is proposed, complementary to that provided by the application of ECOPATH/ECOSIM models. To reconstruct marine foodwebs, OSMOSE is based on the hypothesis that predation is a size-structured process. In all, 12 fish species, chosen for their importance in terms of biomass and catches, are explicitly modelled. Growth, repro- duction and mortality parameters are required to model their dynamics and trophic interactions. Maps of mean spatial distribution of the species are compiled from published literature. Taking into account the spatial component is necessary because spatial co-occurrence determines potential interactions between predatory fish and prey fish of suitable size. To explore ecosystem effects of fishing, different fishing scenarios, previously examined using ECOSIM, are simulated using the OSMOSE model. They explore the effects of targeting fish species in the southern Benguela considered to be predators (Cape hake Merluccius capensis and M. paradoxus) or prey (anchovy Engraulis encrasicolus, sardine Sardinops sagax, round herring Etrumeus whiteheadi). Simulation results are compared and are generally consistent with those obtained using an ECOSIM model. This cross-validation appears to be a promising means of evaluating the robustness of model outputs, when separate validation of marine ecosystem models are still difficult to perform. -

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries. During the International Training Program of the Japan Society for Promotion of Science (ITP of JSPS), two graduate students of Kagoshima University, Mr. -
Status of the South African and Namibian Horse Mackerel
Oceana Sustainability Report 2019 Status and Management of Horse mackerel in South Africa and Namibia, 2019 Capricorn Marine Environmental (Pty) Ltd David Japp, Daniel Droste and Zonke Gumede South Africa Biology and Stock Dynamics Horse mackerel (Trachurus capensis), better known as ‘maasbanker’ in the Western Cape, are similar to other Trachurus species caught globally in many other parts of the world. They are also classified as carangids which typically are game fish and fast swimmers (such as the kingfish commonly caught in the warmer waters of the South African east coast). Maasbanker, however, differ somewhat in that they are primarily filter feeders, although they do have a fairly broad diet that includes plankton and small swimming crustaceans (such as krill) and small fish and squid. What makes them a good commercial species is their shoaling behaviour, with large aggregations occurring in areas where plankton is abundant. Such is the case with the South African fishery, particularly on the east coast around the Agulhas Bank where adult maasbanker shoal and are targeted by the mid-water trawl fishery. Maasbanker are difficult to catch, as they are strong swimmers and migrate up and down in the water column and occur from the shallowest waters out to the deep waters of the continental shelf. In South Africa, the fisheries for massbanker can be broadly separated between three fishery sectors – a fishery using midwater trawls, a second using bottom trawls (typically for hake) and a third fishery targeting juvenile maasbanker using purse seine gear such as that used for sardine and anchovy. These variations, combined with the behaviour of maasbanker, require specific management interventions to ensure that the fishery remains sustainable into the future. -

Queen Mackerel
FACT SHEET Queen mackerel Scomberomorus plurilineatus Family: Scombridae Other common names: Natal snoek, Kanadi kingfish, Serra, Gespikkelde katonkel An elongate, streamlined fish with a large, deeply forked tail. They are silver in colour with a metallic green sheen above and white Description below. A series of dark grey horizontal, broken lines and spots pattern the flanks. The front part of the first dorsal fin is black. Western Indian Ocean, Kenya to South Africa, also west coast of Madagascar, Comoros and Seychelles. In southern Africa common in Distribution Mozambique and KwaZulu-Natal waters, rarely extending into the Eastern Cape, but has been recorded as far south as Tsitsikamma. Near the surface, primarily confined to the inshore zone, often just behind back-line but seldom enters the active surf-zone. Shows a Habitat strong preference for areas close to river-mouths, rip currents off sandy beaches, shallow rocky and coral reefs. Feeds mainly on small fish such as anchovies and sardines but also Feeding takes squid, mantis shrimps, mysids and swimming prawns. Adults migrate into KwaZulu-Natal waters during early summer (October-November) and return to Mozambican waters during Movement winter (May-September). This is likely to be a feeding migration as very few reproductively active fish have been observed in KwaZulu- Natal waters. www.saambr.org.za They reach maturity at 72-78 cm fork length at an age of 2 years. Reproduction Spawning occurs mainly from late winter to early summer (August- November) and is thought to occur along the Mozambique coast. They can reach a maximum size of 117 cm fork length and a weight Age and growth of 12.5 kg. -
