Caracterización de la pesca artesanal con chinchorro de playa en el sitio Las Gilces de la parroquia Crucita provincia de Manabí, durante los meses de abril a Julio del 2014

Abstract

The present study characterizes artisanal fishing using beach seines at the site Las Gilces from April to July 2014. Field visits were conducted and five fishing vessels were identified with fishing as a main activity, and three were identified with fishing was a secondary activity. All fishing vessels are constructed out of fiberglass and have an average length of 6,88 m, a storage capacity of half a ton, and all use beach seines with a pocket to capture fish, and 15 fishermen work together to collect the nets. Forty (40) samples were taken to determine the average catch volume per month, with the highest value yielded in May at 35. 422 Lb., and the lowest in April at only 9. 513 Lb. Fishing effort was calculated based on the capture volume and the time employed to trawl the nets, with the highest monthly average in May at 3,52 Lb/hour, and the lowest in April at 0,99 Lb/m/hour. From these catches, the different species were taken for taxonomic identification; fifty-three (53) species covering twenty-seven families were described. The largest volume of catch was from Ophistonema libertate (Pacific Thread Herring) at 48. 880 Lb., followed by Cetengraulis mysticetus (Pacific Anchoveta) at 18. 600 Lb., the former used in the canning industry and the latter used in the animal feed industry.
