| dc.description | The small-scale cuttlefish (Sepia officinalis) fishery in Galician waters (NW Spain) was studied using a model based on data obtained from fishers. This model was applied using information obtained from the small-scale Galician fleet in 1998. A total of 139 personal interviews were carried out at 62 Galician ports. This information was used to estimate catches per unit effort (CPUE) and total catch for the cuttlefish gillnet fishery. The fleet, which fishes in Galician waters within ICES divisions VIIIc and IXa, was composed of two groups: 600 vessels fishing for cuttlefish in only five months of the year (short season: November to March), and 141 vessels fishing for cuttlefish all year (extended season). Estimated total catch during the fishing season for the whole Galician fleet was 1301 t (869 t short season and 432 t extended season) and average CPUE values were 14.5 kg haul-1 trip-1 vessel-1 (short season) and 12.8 kg haul-1 trip-1 vessel-1 (extended season). To test the reliability of the model, the outputs obtained from the model for a subset of 37 ports (59.7% of all ports) were compared with the official catch statistics for these ports. Differences between total catches estimated by the model and those determined directly at these ports were not significant. | - |
| dc.description | La pesquería artesanal de enmalle de sepia (Sepia officinalis) en aguas de Galicia (NO de España) se estudió usando un modelo basado en la información obtenida de los pescadores locales. Este modelo utilizó los datos obtenidos por entrevistas a pescadores para estimar las capturas por unidad de esfuerzo (CPUE) y capturas totales en la pesquería artesanal de enmalle de sepia (Sepia officinalis) en Galicia durante 1998. Un total de 139 entrevistas fueron realizadas en 62 puertos. Esta pesquería está compuesta por embarcaciones que operan en la costa de Galicia (divisiones del ICES VIIIc y IXa). La flota se divide en dos grupos: uno formado por 600 embarcaciones que opera cinco meses al año (temporada corta, entre noviembre y marzo), y un segundo grupo de 141 embarcaciones que pescan todo el año (temporada extendida). El modelo estimó que la captura total en 1998 fue de 1301 t (869 t para la temporada corta y 432 t para la temporada extendida), con CPUE de 14.5 kg. lance-1 viaje-1 barco-1 y de 12.8 kg lance-1 viaje-1 barco-1 para las temporadas corta y extendida, respectivamente. Para evaluar la fiabilidad del modelo se obtuvieron y compararon las estadísticas de 37 puertos en los que opera la flota (59.7%) con las estimaciones generadas para esas localidades. No se observaron diferencias significativas entre las capturas totales obtenidas por el modelo y las registradas en las Cofradías. | - |
