description |
The Messolonghi-Etoliko lagoon is one of the largest lagoon system in the northern Mediterranean coast. This area contains six clearly distinct lagoons with different topographic and hydrological features. The fishery landings of the lagoons are based on the ontogenic and seasonal migrations of the species. The total annual fishery landings of the barrier fish traps are estimated as 195 mt and are mainly composed of 16 species belonging to 8 families. Eel (Anguilla anguilla), the four species of Mugilidae (Liza saliens, L. aurata, L. ramada and Mugil cephalus), the two species of Sparidae (Sparus aurata and Diplodus annularis) and one species of Mullidae (Mullus barbatus) represent more than 92% of the total annual landings. The composition of the fishery landings varies between lagoons. The cluster analysis showed three groups of lagoons. The first group comprised lagoons in which the landings were dominated by eel, the second group was dominated by Mugilidae species and S. aurata, and the third by L. ramada and M. cephalus. The diversity index of the fishery landings is fairly constant in time, except for the Etoliko lagoon, where repeated anoxic crises decreased the diversity index value to almost zero in 1992. All the landing series showed a dominant annual cycle. Two seasonal patterns of the fishery landings were observed and linked to the fish spawning behaviour and/or their reaction to environmental forcings. The first one concerns species caught from summer to early autumn and the second pattern concerns species trapped during their autumn to winter offshore migration. La formación de lagunas de Mesologi-Etolikó es una de las reservas naturales marinas más grandes de la franja septentrional del Mediterráneo. Este conjunto está compuesto por seis distintas marismas, con diferentes características topográficas e hidrográficas cada una de ellas. La producción piscícola de las marismas se basa en los movimientos estacionales de las especies hacia el mar. Del estudio del trampeo se concluye que los movimientos migratorios equivalen a 195 toneladas y se componen principalmente de 16 especies las cuales pertenecen a 8 familias: anguila (Anguilla anguilla), cuatro especies de Mugilidae (Liza saliens, L. aurata, L. ramada, y Mugil cephalus), dos especies de Sparidae (Sparus aurata y Diplodus annularis) y una especie de Mullidae (Mullus barbatus). Estas especies representan más del 92% de los desplazaminentos anuales. Estos varían entre las distintas marismas. El análisis cluster distingue tres tipos de marismas. El primer grupo incluye las marismas cuyos movimientos son principalmente de anguila; el segundo grupo de Mugilidae y de S. aurata, y el tercero con movimientos sobre todo de L. ramada y M. cephalus. Los desplazamientos de estas especies presentan un ciclo anual importante. Así mismo, se han observado dos clases de movimientos estacionales (en verano y a principios de invierno) que se asocian a los movimientos migratorios de estas especies hacia el mar para su reproducción y/o provocadas por consideraciones adversas. |
