| Sequential population analysis on Long Tail Hake (Macruronus magellanicus)from the Southwest Atlantic. Years 1985-1995. VPA on the Long Tail Hake (Macruronus magellanicus), based on data covering the years 1985 up to 1995, was performed to assess the current state of the stock. Simulation trials, inducing uncertainty about both the natural mortality rate and recruitment were also accomplished, to evaluate the risk of overfishing which is associated to different fishing alternatives, always under the assumption of a single and closed Long Tail Hake population. CPUE data were not appropriate for tunning, so the traditional VPA has been applied. During the period of study, stock biomass and spawning stock biomass showed an increased trend. Long and short-term... |

| 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... |

| Monitoring results on the abundante of queen conch (Strombus gigas) are presented. Field Works were done in the comercial fishing ground at Jardines de la Reina Nacional Park, south-east region of the Cuban shelf. Means a protected area under control of the Ministry of Science, Technology and Enviroment, and its local authorities. According to the fishery importance of this zone for the conch, a joint research assessment were done, aim to evaluate the actual possibilities for a sustainable commercial operation, following an ensure scope. By the abundance estimation observed is allowed a MSY of 119 metric tons (living weight), from October 2008 until April 2009. From obtained results, it was agree a catch license for the fishery enterprise of Camaguey... |

| Se presentan los resultados de la evaluación efectuada al área comprendida entre la Bahía de Nuevitas y Cayos Ratones (210 20`N--210 30`N y los 770 10 W—770 30`W), en la plataforma Norte de la Provincia de Camaguey. Esta localidad ha sido objeto de explotación por la EPI de Camaguey (EPICAM). A partir de los resultados de las densidades de individuos como índice de la abundancia y la estructura poblacional encontrada, se propone un potencial de captura de 106 TM/año (peso entero), como suele reportarse en Cuba, que equivale a unas 7.8 TM de carne sin procesar eviscerada y sin manto, a desembarcar por la flota escamera local. Se excluye la zona comprendida entre el Faro de Maternillo y Cayo Sabinal, por declararse Reserva Ecológica, desde el 2009. Se... |

| Period 1985-2001. A stock assessment of Patagonian hoki of the Southwest Atlantic was carried out by using data from the years 1985-2001. A cohort analysis, fitted with some survey abundance indices was used in an adaptive conceptual framework. Simulation trials were performed to project the evolution of the fishery, to evaluate the risk of over-fish the stock under different exploitation levels, and to estimate Biologically Acceptable Catches (BAC). Both total biomass and spawning stock biomass showed increasing trends resulting from four strong year classes (1993, 1995, 1996 and 1998). Total biomass at the beginning of 2001 was estimated to be 2.5 million tons, and spawning stock biomass at the spawning time (August) was estimated to be around 1.28... |

| The concept of technical viability is defined as a combination of factors including fishery resource. Ecology, gear technology, manpower and entrepreneurial skills financial inputs and product markets. A clear drop in catch per trawler per year in Nigeria is attributed mainly to inadequate cash flow to operate vessels in the face of high fuel costs, lack of spare parts and repair facilities, and some growth over fishing of ground fish stocks. The transition from artisanal to rapid industrial mechanized fishing has not been matched by the availability of skilled local manpower to effectively operates and service electronic, hydraulic and refrigeration equipment of modern trawlers. While Nigerian financial institutions have to some extent financed trawler... |
