| As part of a global comparative study of user-participation in fisheries management, a neo-institutional economic framework analysis is applied to the South African Deep-sea Hake Fishery to evaluate past and present co-management arrangements. It is postulated that the comprehensive partnerships that exist will struggle to remain legitimate and functional during major changes in the access-rights regime. The government is redistributing quota to new entrants and previously-disadvantaged South Africans, resulting in competition between the established demersal trawl fleet and a new longline sector for access rights. The established industry is currently undertaking restructuring via investment schemes, joint ventures and share agreements. The relationship... |

| The structure of meiofaunal communities was surveyed in 17 stations in Nipe Bay, Cuba in July, 2001. Levels of Nickel (all stations) are higher than in several bays in Cuba, probably due to natural causes. The levels of Copper, Zinc, Fe and Manganese indicate a relative low pollution, likely related to the presence of urban settlements. There is decrease in the total density and number of taxa of meiofauna in the stations with higher levels of metals; the copepods appear to be particularly sensitivity to metal pollution. The stations located at the mouth of the bay have the lowest levels of contamination and the highest total density of organisms and taxa richness, probably due to a more intense turnover of the waters in this area and consequent lower... |

| This document presents a brief summary of the main general French purse-seiners activities in the Indian Ocean since the beginning of their fishery in 1981: catch by species and fishing type (log and free swimming schools), effort and sampling for sizes and species composition. The description of statistics gathering, sampling and processing procedures are reported in a specific document presented at the meeting (WPDCS/99/09). |

| Fishing is known to be one of the oldest occupations of mankind and in Lake Victoria (Kenya); it has been largely practiced at artisanal levels. Despite this, poverty amongst the fisher folk remains high. Why the fisher folk remain in perpetual poverty was the key research question for this study. Sampling was conducted on 12 landing beaches between June and August 2004. Data was obtained using survey questionnaires; personal interviews were made using open-ended questions and beach observations. Results from this study indicates that 179 fishers sampled earned an average income of Ksh. 107,063 each in a year with modal income of Ksh. 57,600 while in a day they earned an average income of Ksh. 518 each with modal income of Ksh. 200. Fishers perceived that... |

| Para evaluar el efecto de diferentes relaciones proteína/energía en el crecimiento de juveniles de langosta Panulirus argus (peso medio inicial de 180 ± 3.8 g), se desarrolló un diseño experimental totalmente aleatorizado durante 5 meses, con 7 tratamientos y 16 repeticiones. Se ensayaron dietas con 25, 35 y 45% de proteína, con niveles altos y bajos de energía (324-359 Kcal/100 g) y relaciones proteína/energía entre 70.5 y 137.2 mg de proteína/Kcal. Al final del bioensayo se determinaron los indicadores nutricionales básicos y se comparó el flujo energético producido en la respiración y excreción nitrogenada entre langostas alimentadas con las dietas isocalóricas (356 Kcal/100 g) de 25 y 45% de proteína. Se concluyó que las langostas requieren para crecer... |

| This workshop was organised by the Marine Conservation office in Dakar of the World Wide Fund for Nature (WWF), Novib (Dutch development NGO), Fenagie (National Federation of fisheries collectives in Senegal) and Scomber Consultancy (consultancy in The Netherlands for fisheries management and marine wildlife), with the financial support of the David and Lucile Packard Foundation (USA). The workshop proper was preceded by a one-day introduction and application to ‘FishMan’. FishMan is a role-play that simulates long distance fleet fisheries in developing nations’ coastal waters in a computer network. It is designed to familiarise people with negotiations and the issues involved in international fisheries. Following the WWF-publication of a series of... |

| Con el objetivo de determinar el efecto de diferentes relaciones proteína/energía (P/E), sobre el crecimiento de juveniles de Camarón Blanco Litopenaeus schmitti , mediante la utilización de dietas prácticas, se desarrolló un diseño experimental completamente aleatorizado, a escala de laboratorio, durante 59 días. Se evaluaron 12 dietas con diferentes niveles de inclusión de proteínas, lípidos y carbohidratos. El crecimiento fue mayor en los camarones que se alimentaron con las dietas que contenían 33 y 28% de proteína, alcanzando su valor máximo en el intervalo de la relación P/E comprendido entre 105-127 mg de proteína/Kcal. Los indicadores nutricionales evaluados, también fueron mejores para aquellos organismos alimentados con las dietas de alto... |

| This study presents some results of monitoring the beaches at East of Havana City, Cuba, during February and August corresponding to the rainy and less rainy seasons, respectively. For the bacteriological analysis were carried out 5 samplings in a period of 30 days, the rest of the samples was collected as punctual samples. The results are compared with those obtained in other samplings, specifically with 2004 period and with the requirements in the Cuban Standard NC: 22, (1999). Practically, the whole area showed pollution indicators deteriorated, such as: the permanganate oxidability value, bacteriological indicators and hydrocarbons, the last one corresponds to a lightly polluted area by hydrocarbons. The most affected areas were the outlet of the... |

| Coral reefs are very sensitive to the increment in nitrogen concentrations and phosphorus, since these compounds propitiate the macroalgae growth, resulting in the degradation of coral reefs. With the purpose of assessing the degree of nutriphication of the coral reefs in Los Canarreos Archipelago, located in the periphery of the Gulf of Batabanó, and those located in the outer area of Sabana-Camagüey Archipelago (SCA), three samplings were executed in the reefs of Los Canarreos Archipelago (August 1999, March 2000 and August 2000). In SCA, samplings were done in May 2002 and August 2003. The parameters evaluated were nitrates + nitrite, ammonium, total nitrogen, inorganic phosphorus and total phosphorus. The nutrient contents in the reefs located in the... |

| The study is an attempt to provide a model or prototype for basic information on fishing such as required by fishermen in Ghana. It is based on questions raised by the fishermen themselves. Numerous researches have been carried out on marine and aquatic resources but the findings remain abstract to fishermen, the majority of whom are illiterate. The information needs of the fishermen is repackaged in easily comprehensible form. Types of fishing implements, techniques of fish preservation, marketing methods, fish farming and further sources of information are given. The next step is to translate this information into the local languages. |

| An assessment of the coastal erosion problems along selected stretches around the Zanzibar coastline as well as along the mainland coastline of Tanzania, indicated a significant contribution to the problem by human activities. During the study, 56 eroding beaches were examined to assess the extent of anthropogenic activities to the problem. Human-induced erosion was observed at nine sites. By interfering with natural processes, human activities either initiated erosion or enhanced its rate. The activities identified fall into three categories namely, removal of beach material, removal of the protection against wave battering and obstruction of sediment supply. |
