Variabilidad circadiana de la tasa de captura y la estructura de tallas en camarones e ictiofauna acompañante en la pesquería de arrastre del Mar Caribe de Colombia

Abstract: RESUMEN.A partir de muestreos realizados a bordo entre julio y septiembre de 2004, se examinaron los cambios asociados con la hora del día en las tasas de captura y estructura de tamaños de los camarones (Farfantepenaeus notialis, F. brasiliensis), las capturas incidentales, los descartes y las 12 especies de peces con mayores capturas en cada una de las dos zonas de pesca (norte y sur) en que opera la flota de arrastre de camarón en el Mar Caribe de Colombia. La tasa de captura de camarón fue significativamen… Show more

“…The fact that this species, the most important in the 2006-2007 survey (see table 14 from García 2010), has become a secondary item in the database, reinforces the inference of decadent stocks in this species (Table 3). Duarte et al (2018) In accordance with its global predominance, gillnets landings disaggregated by department showed the same pattern of dominance (Table 4). Excep-tions are Choco, Cordoba and Magdalena, where handlines and beach seines are responsible for most landings (Table 4).…”

“…The high abundance of Cathorops mapale in both areas, also reported by other authors (e.g. Duarte et al 2006), can be explained by the fact that it inhabits marine-brackish and freshwater environments in tropical and subtropical waters along the world's continental shelves, on muddy or sandy bottoms in the lower parts of rivers, estuaries and coastal lagoons of mangroves (Herazo et al 2006;Betancur-R. et al 2007). In the areas studied there are favourable conditions for growth of this species, especially in the Gulf area, due to salinity decreases in the mouths of large rivers in the area (Ruiz-Ochoa et al 2012).…”

“…Se esperaría entonces que la región de La Guajira, caracterizada por presentar las praderas de pastos y macroalgas más extensas del país (Díaz-Pulido 2000, Gómez-López 2009, Nieto-Bernal et al 2011, albergara una importante población de caracol pala, lo que es contrario a lo hallado en este estudio. Sin embargo, durante aproximadamente dos décadas, los hábitats someros de la plataforma continental de la Guajira junto con su fauna fueron objeto de una gran presión destructiva a causa de los arrastres camaroneros (Viaña et al 2002, Duarte et al 2006, Flórez-Leiva et al 2007. Esto podría estar asociado con la baja abundancia de S. gigas.…”
