| Topics on Lake Victoria limnology, benthic fauna, stock assessment, catch assessment survey, gear selectivity, fisheries ecology, fish parasites and marketing economics are covered. Management and conservation of the lake's fisheries and other aquatic resources are discussed. Dialogue between fishermen, scientists and administrators is stressed, measures to be undertaken are addressed and further research is recommended. |

| In this work we present a process of risk analysis related to the adoption of a Total Allowable Catch (TAC)based in series of allowable biological catches which contain uncertainty derived of the recruitment patterns which characterize the stock. With the information obtained by the F0,1, and F30. RDP, the exploitation ratio and with the 500 values of the projected biomass of 1995 obtained by Monte Carlo simulation, we calculate the distribution of the allowable biological catches under a scheme of F0,1, and F30. RDP andfor a natural mortality of 0.38. The selected TAC is expected to beas closer as possible to the reference fishery mortality F0,1, and F30. RDP. As a result of the present risk analysis in this study in Macruronus magellanicus of the SW... |

| 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... |

| The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed... |

| Whitemouth croaker Micropogonias furnieri fishery during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet... |

| Argentine black drum distributes mainly in shallow waters associated to estuarine areas, particularly to Samborombon Bay where it may be detected throughout the year. Nevertheless, it can also be spotted more southwards (40°S) and at deeper waters. During summer, catches of the species in Samborombon Bay are practically negligible, probably due to movements towards shallow waters out of reach of the inshore commercial fleet. Landings increase in autumn and show peak values in winter, coinciding with the fishing season of whitemouth croaker, Micropogonias furnieri, whose geographical distribution within the bay overlaps that of black drum. As of 1995, landings of black drum showed increasing trends both in Argentina and Uruguay. These increments coincide... |
