Abstract

The present work titled characterization of artisanal fishing in the estuary of the Good Signs in Quelimane and Inhassunge from 2009-2016, in the southern region of Zambézia province between latitudes (17º54'32.41 ''S) and (18º2'0.44''S) and lengths (36º48'38.97''E) and (36º58'39.13''E) respectively. The study was conducted at the site intentionally selected to identify the main gear used in artisanal fishing in the Bons Signals estuary, to describe catches by gear, to identify and quantify the species caught by the main gear used in the estuary of good signals and to determine the fishing yield by art. The fishery statistics data used in this study came from the artisanal fishery sampling system of the National Institute of Fisheries Research Delegation of Zambézia, in the district of Quelimane. The time series of data for the period 2009-2016, relative to the trawling gear for the beach, gill, longline, chicocota and hand line available in the database of this institution in this province was used. The data relate to fishing effort, catches and catches per effort unit. The results showed that the most used gear in the period of 2009-2016 in relation to the artisanal fishing in the estuary of the good signs, were dragged to the beach, gill, longline, chicocota and line of hand. The hand line had a total catch of 774.84 tons, trawling to the beach 4481.33 tons, 240.76 tons gill, 62.38 ton longliners and 4651 ton chicocota. For the identification of the species captured by the main gears, the fishery statistics data from the artisanal fishery sampling system of the National Fisheries Research Institute were used and for the quantification of the main species most caught in the estuary of the good signs, it was used the sum of annual catches. The catch yield per art was 1569.5 ton for hand line, 10836.6 ton for trawling, 240.7 ton gill, 4651 ton longline and chicocota.
