SPATIAL AND TEMPORAL DISTRIBUTION OF THE CAPTURES OF SEABOB SHRIMP, IN THE ARMACAO DO ITAPOCOROY, PENHA, SC

Xiphopenaeus kroyeri e considerado sobreexplotado nas regioes Sudeste e Sul, devido a elevada pressao pesqueira sobre os estoques, com juvenis sendo capturados em aguas mais rasas, como praias, baias e enseadas, enquanto que os adultos ocorrem ao redor dos 20 metros. Esse trabalho teve como objetivo analisar a distribuicao espaco-temporal das capturas do camarao sete-barbas na Armacao do Itapocoroy, Penha, SC, ao longo de um ciclo anual. Entre julho de 2010 a junho de 2011 foram realizadas coletas mensais nas isobatas de 10, 20 e 30 metros, com duracao de 15 minutos (uma amostra e duas replicas), a bordo de uma embarcacao tipo baleeira. A populacao de X. kroyeri apresentou flutuacoes sazonais, com as maiores concentracoes e comprimento de adultos observados nos 20 metros. A rara captura de camaroes na isobata de 30 metros, frente ao elevado esforco amostral, indica provavelmente que a especie nao utiliza a isobata como area de vida na regiao de estudo. A atuacao da frota pesqueira em areas mais rasas na Armacao do Itapocoroy, principalmente no periodo de recrutamento que se inicia em novembro, gera grande preocupacao quanto a manutencao dos estoques, dada a elevada abundancia de juvenis nestes locais e a importancia destes na continuidade dessa modalidade de pesca.Original Abstract: Xiphopenaeus kroyeri is considered to be overfished in the southern and southeastern regions, due to intensive fishing, with juveniles being caught in shallower waters, near beaches, in bays and inlets, whilst adults occur at depths of about 20 m. This study aims to analyze the space/time distribution of captures of sea-bob-shrimp in the ship-yard/surfzone of the Armacao do Itapocoroy, Penha, SC, during one full year. Monthly catches (one sample being divided in two), lasting 15 minutes, were undertaken at depths of 10, 20 and 30 meters between July 2010 and June 2011, using a whaling-boat. The population of X. kroyeri presented seasonal variations, the greatest concentrations and adults were observed at 20 metres. The rare caught at 30 meters front of the high sampling effort indicated that the species probably doesn't use this isobath as living area in the study region. The action of the fishing fleet in the shallower areas in Armacao Itapocoroy, mainly during recruitment which starts in November, raises concern about the maintenance of species stocks, given the high abundance of juveniles in these shallow sites and their importance in the continuity of this kind of fisheries
