Arana, D

Abstract

Fisheries products traded in fish markets in the Andalusian (Spain) between January to October2015 was 49.814 T with a market value of € 131,09 million. By fishing gear, the coastal longline fleet in surface represents 3,9 % of the size of the total GT tonnage of the small – scale coastal fleet, with a volume of capture of 549.016,44 kg being 1 % of total fish production of the artisanal fleet. In 2011, this injected revenue worth € 3.053.873, 70 (2, 1 %) of the total traded value. With an objective to evaluate the marketing channels of catches from the longline a comprehensive analysis of sales notes submitted to the fisheries authority during the period 2013-2015 was performed. In parallel, an in situ monitoring of the process of first sale of products in the fish market of El Puerto de Santa Maria in Cadiz (Spain) was done, as well as surveys ofagents involved in the capture and subsequent marketing. The analysis reveals that the main surface longline catches are, by order, swordfish (Xiphias gladius), blue shark (Prionace glauca) and to a lesser extent, mako (Isurus oxyrinchus). The study also provides valuable information about the seasonality of catches in relation to the fishery and the main landing points. With respect to market value, the swordfish was most valued, with average price of 6. 05 € /kg, compared to 4.71 and 1.97 € / kg for the mako and blue shark respectively. In recent years there has increased decline in the catches of mako and blue shark to a lesser extent. This is caused by increasing demand for consumption and for shark fins.
