Biologia, pesca e potencial pesqueiro da Guarassuma, "Carangoides crysos" (Cuvier, 1833), capturada na costa do Estado de Pernambuco entre 2004 e 2006

The blue runner, Carangoides crysos (Cuvier, 1833), of family Carangidae, is a coastal-pelagic species found, on the eastern Atlantic from Senegal do Angola and, on western Atlantic, from Nova Scotia do Brazil, where is caught all along its northeatern region. Trawl nets, gillnets and purse-seines are the most commonly employed fishing gear for its capture. It is the third most-caught species of family Carangidae, being used mainly as bait in commercial and recreational fisheries. There seems to be a size selectivity by different-meshed gillnets as to depth, implying that the juvenile are demersal and the adults area coastal-pelagic. Among the carangid fishes landed at Barra de Sirinhaem, the blue runner's yield is second only that of yellow jack (Carangoides bartholomaei), with an increasing price over recent years, but it is not well represented in fish landings of Northeast Brazil. In the gillnet fishery, with 40 mm meshes in bar measure, the mean catch length was 33.5 cm TL. Given the economic importance of the blue runner as a regional fishing resource, the results herein obtained should be taken as basic data for supporting management measures for that species in Brazil
