We hope that your stay at the Eastern Cape during the symposium will be fruitful and enjoyable. This book of abstract contains general information as well as guidance for your stay in the Eastern Cape and to enhance your better participation during the symposium. The booklet contains a detailed symposium programme, abstracts of all the presentations and posters, and an index of authors and their addresses. Plenary sessions are scheduled for Monday to Thursday, preceded by key note presentations. Five parallel sessions will be held during these days. On the afternoon of Tuesday 27th a poster session will be held from 14:00 to 17:30h. Delegates should note that the symposium will start at 09:00h each morning of the five days of the symposium, health breaks will be held at 10:30 and at 15:30, while lunch will be served from 12:30 to 13:25, all served at the symposium venue. GENERAL INFORMATION EASTERN CAPE - AN ORIENTATION The Wild Coast is the northernmost stretch of the Eastern Cape and the beginning of the recently proclaimed Pondoland Marine Protected area. It is a warm temperate coast with numerous estuaries, river mouths, rocky shores and sandy beaches. It is the site of the beginning of the yearly Sardine Run on South Africa’s East Coast and harbours a wealth of marine biodiversity. It has protected areas and large portions which serve local communities’ subsistence needs. It has been spared the relentless development that most of South Africa’s coastline has been subjected to and as such serves as a reminder of the beauty that natural environments offer. As the venue for WIOMSA’s 9th Scientific Symposium we hope that you are able to take a moment during your visit to enjoy the natural beauty it has to offer. SYMPOSIUM VENUE WIOMSA’s 9th scientific symposium will be held at Wild Coast Sun Resort. The hotel is located within the borders of the Eastern Cape and only a two hour scenic drive along the South Coast from Durban’s King Shaka International Airport

    CORE Metadata, citation and similar papers at core.ac.uk Provided by South East Academic Libraries System (SEALS) OPTIMISATION OF A SAMPLING PROTOCOL FOR LONG-TERM MONITORING OF TEMPERATE REEF FISHES A thesis submitted in fulfilment of the requirements for the degree of MASTER OF SCIENCE of RHODES UNIVERSITY by RHETT HAMILTON BENNETT June 2007 ABSTRACT Marine Protected Areas (MPAs), the Ecosystem Approach to Fisheries management (EAF) and Integrated Coastal Management (ICM) have been identified as possible alternatives to traditional linefish management measures, which have largely failed. Monitoring and assessment of fish communities on a long-term basis is necessary, and will provide a means to evaluate the effectiveness of such management measures. Therefore, standardised protocols and optimal sampling methods for long-term monitoring (LTM) and assessment of coastal fish communities are essential. This study aimed to identify suitable methods and develop a protocol for assessment of inshore reef fish communities. A suitable location for evaluation of proposed methods was identified in the warm temperate biogeographical region of South Africa, encompassing the well-established Tsitsikamma Coastal National Park MPA and an adjacent exploited area. Chrysoblephus laticeps (roman) was identified as an indicator species for the study, as it has been well-studied and is well represented in the area. Underwater visual census (UVC) and controlled fishing were identified as suitable methods. UVC transects were found to be superior to point counts, in terms of sampling efficiency, variability, bias and required sample size. An effort of two angler hours per fishing station was shown to provide low catch variability, while at the same time a representative catch and low overall cost and required time.

  • Review of the Species of the Genus Dentex (Perciformes: Sparidae) in the Western Pacific Defined As the D

A, Suppl. 1, pp. 29–49, March 22, 2007 Review of the Species of the Genus Dentex (Perciformes: Sparidae) in the Western Pacific Defined as the D. hypselosomus complex with the Description of a New Species, Dentex abei and a Redescription of Evynnis tumifrons Yukio Iwatsuki1, Masato Akazaki2 and Nobuhiko Taniguchi3 1 Division of Fisheries Sciences, Faculty of Agriculture, University of Miyazaki, 1–1, Gakuen-kibanadai-nishi, Miyazaki 889–2192, Japan E-mail: [email protected] 2 Deceased on 12 May 1999 3 Laboratory of Applied Population Genetics, Graduate School of Agriculture, Tohoku University, Tutumidori, Amamiya-cho, Aoba-ku, Sendai-City, 981–8555 Japan E-mail: [email protected] Abstract The lectotype of Chrysophrys tumifrons designated by Boeseman (1947) is a specimen of the species currently recognized as Evynnis japonica Tanaka, 1931. The name is, therefore, the senior synonym for that species. Dentex spariformis Ogilby, 1910, based on specimens collected at Moreton Island, Queensland, Australia, is redescribed and resurrected as a valid species, having previously been synonymized with D. tumifrons (Temminck and Schlegel, 1843). Dentex abei sp. nov. is described from ten type and 30 non-type specimens collected in the Ryukyu Islands, Chichi-jima of Ogasawara Islands (ϭBonin Islands), Japan, and Luzon Island, Philippines. These two Dentex species, together with D. hypselosomus Bleeker, 1854 and D. fourmanoiri Akazaki and Séret, 1999 are recognized as a “Dentex hypselosomus complex” and reviewed on the basis of western Pacific and southern Indonesian material. Dentex hypselosomus differs from the others in having three eye-sized fluorescent yellow blotches dorsally, plus a small yellow spot posteriorly on the soft dorsal fin base (vs.

  • Polysteganus Praeorbitalis (Pisces: Sparidae) to Climate Change in the Agulhas Current System
    Modelling the spatial and genetic response of the endemic sparid: Polysteganus praeorbitalis (Pisces: Sparidae) to climate change in the Agulhas Current system A thesis submitted in fulfilment of the requirements for the degree of Master of Science of Rhodes University Grahamstown, South Africa. By: Devin Neil Isemonger November 2013 i Abstract Abstract The Scotsman Seabream, Polysteganus praeorbitalis, is one of several large, slow-growing members of the Sparidae family of fishes endemic to the Agulhas Current system in the Western Indian Ocean (WIO). Relatively little research has been conducted on this species despite its importance to both recreational and commercial line fisheries in South Africa and the drastic decline in catch per unit effort (CPUE) that has been recorded since the 1940s. Changing sea temperatures as a result of global climate change are further expected to affect the distribution and abundance of many fish species based on their thermal tolerances, life histories and population structures. The ability of these species to shift their distribution and adapt to new environments and thermal conditions will depend to some degree on the levels of genetic variation and gene flow, within and between populations. A combined approach using species distribution modelling and genetic analyses may prove to be a useful tool in investigating the potential effects of climate change on the distribution and genetic diversity of species. An ensemble species distribution model (SDM) based on 205 occurrence records and 30 years of Reynolds Optimum Interpolated (OI) sea surface temperature data was constructed to predict the distributional response of P. praeorbitalis to climate change in the Agulhas Current system.

  • Fish Surveys in Exploited and Protected Areas of the Pondoland Marine Protected Area with Consideration of the Impact of the Mpa on Coastal Fisheries
    FISH SURVEYS IN EXPLOITED AND PROTECTED AREAS OF THE PONDOLAND MARINE PROTECTED AREA WITH CONSIDERATION OF THE IMPACT OF THE MPA ON COASTAL FISHERIES by JADE QUINTON MAGGS A dissertation submitted in fulfilment of the academic requirements for the degree of MASTER OF SCIENCE in the School of Biological & Conservation Sciences, University of KwaZulu-Natal, Durban. Oceanographic Research Institute JANUARY 2011 ii ABSTRACT ______________________________________________________________________________ The line-fishery in KwaZulu-Natal, on the east coast of South Africa, experienced a rapid decline during the 20 th century. The stocks of some important fishery species collapsed due to over-fishing, which led to the Minister of Environmental Affairs and Tourism declaring a state of emergency in the line-fishery in 2000. More restrictive regulations were implemented and the importance of marine protected areas became recognised. In June 2004, 80 km of the Pondoland coast was declared a multiple-use marine protected area. This coastline is a zone of transition between the Natal and Agulhas biogeographic regions and had been identified as a critical gap in South Africa’s marine protected area network. Part of the protected area is a 40x10 km no-take area, which is closed to offshore exploitation. The primary objectives of the closure, as gazetted, are the conservation of biodiversity and the rebuilding of commercially important line-fish stocks, which have been depleted by over-fishing. Not mentioned in the legislation, but of significant importance is the benefit of the Pondoland Marine Protected Area to nearby fisheries through the export of fish biomass. Between 2006 and 2010, experiments were conducted to evaluate the outcome of the fishery closure.
