Última Multigear fishery of Nile perch (Lates niloticus) in the Winam Gulf of Lake Victoria: with special reference to mortality, selection and catch/effort data 20 Manyala, J.O.; Rabuor, C.O.. A survey of multigear fishery of Nile perch (Lates niloticus) in the Winam Gulf of Lake Victoria indicates that total mortality coefficient (Z) determined from longline fishery using hook number 6 was double that of hook number 7. Total mortality coefficient determined from gillnets and beachseines were lower than those of hooks. The catch per unit effort (C/f) measured using different criteria indicated an increase for all gears in 1990 as compared to 1989 except for gillnets. A two-fold increase in unit effort (f) increased the C/f for mosquito seines by only 30%. The typical exponential decay of C/f with increasing f of exploited stock in equilibrium was lacking in the case of Nile perch in the Winam Gulf.

There is a lack of scientific information about the artisanal fishery in the de la Costa County (Buenos Aires province, Argentina). Moreover, this artisanal sector does not have fishing statistics because local fishermen are not obliged to hand in fishing reports, where even basic data on catch and fleet effort should be included. The main objective was the analysis of the artisanal fishery in the de la Costa County from the biological, economic and social point of view. One 132 sample stations were analyzed between 56 degree -57 degree W and 36 degree -37 degree S from 1992 to 1999. Moreover, information on the artisanal fleet, environmental conditions and the arrival of tourists to the de la Costa County was also analyzed. Fishing yield (FY) per boat was...

This paper deals with the design and application of different fishing gears tested in the Beagle Channel (Tierra del Fuego, Argentina) with the supervision of the technical personnel of INIDEP Fishing Gear Group, the support of the General Directorate of Natural Resources (known today as SRNyAH) of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province and the participation of local fishermen. Activities started as a result of an agreement between the INIDEP and the SRNyAH ratified in 1994. The fishing gear tested, which consist of two paired midwater trawl nets, a gill net, a surrounding net, a bottom lingline, a pot for kingklip and a line of octopus traps may be used in vessels ranging from 30 to 120 HP in coastal waters, channels and inland...
