[EN] A total of 26 effective trawl hauls using a remotely operated trawl cod-end closure system were carried out to determine whether samples collected in a rear section of the cod-end and in a front section of the cod-end were homogeneous, and can be used as reliable replicates for community sampling and resource assessment. Comparative analyses of these sample hauls and 25 other hauls that did not use the cod-end closure system were also performed. The results indicate certain technical difficulties in the practical operation of the system and that samples were not homogeneous either between the cod-end sections in the same haul or between hauls. The causes of the sample variability in catches from trawl surveys are discussed. |

[ES] Se han realizado un total de 26 lances con un sistema de control remoto para el cierre del copo en redes de arrastre, con el fin de verificar la utilidad y eficiencia de este sistema para la separación de muestras homogéneas entre las dos partes en que se divide el copo una vez cerrado. También se han llevado a cabo análisis comparativos con otros 25 lances en los cuales no se utilizó dicho sistema. Los resultados indican ciertas dificultades técnicas en el funcionamiento práctico del sistema y que las muestras no fueron homogéneas ni entre lances ni entre las dos partes en que se divide el copo. Se discuten las posibles causas de dicha variabilidad y su implicación en las campañas de evaluación pesquera. |

These experiments were conducted in the framework
of the “Nerit project” (CICYT, MAR98/0935) and the Llucet project (EC, FAIR CT 97/3522). |
