Towing gears are known to produce several kinds of effects on benthic ecosystems. As small organisms and benthic species with faster growth rates and shorter life histories can withstand the fishing mortality and benefit from reduced competition or predation, trawl fishing can enhance their prolifer...

| description | Towing gears are known to produce several kinds of effects on benthic ecosystems. As small organisms and benthic species with faster growth rates and shorter life histories can withstand the fishing mortality and benefit from reduced competition or predation, trawl fishing can enhance their proliferation. Thus, trawl fishing can lead to biomass loss and production increase, since smaller specimens are more productive than bigger ones. In the present study we evaluate the effects, if any, of trawling on benthic crustacean macrofaunal production rates. Sampling was carried out in two neighbouring sites in the central Adriatic Sea (central Mediterranean), one affected by fishing activity and one not. Production and production/biomass (P/B) ratio of 13 species of peracarid and eucarid crustaceans were estimated using the Hynes size-frequency method. Estimates measured at both sites were compared in order to test the hypothesis that higher production and P/B values should occur in the fished area rather than in the unfished one. Our results indicated that the effects on the species are more complex than expected in regard to this hypothesis, and that they depend on the ecological and behavioural characteristics of the selected species.
Las artes de pesca de arrastre pueden tener varios tipos de efectos sobre los ecosistemas bénticos. Considerando que los organismos pequeños y las especies bénticas con mayores tasas de crecimiento y menores expectativas de vida pueden soportar la mortalidad por pesca y beneficiarse de una reducción en la competencia o depredación, la pesca de arrastre puede propiciar su proliferación y, por ende, resultar en una pérdida de biomasa y un incremento en producción, ya que las especies de menor talla son más productivas que las de mayor tamaño. En el presente estudio se evalúan los efectos, si es que los hay, de la pesca de arrastre sobre las tasas de producción de la macrofauna béntica. Los muestreos se realizaron en dos sitios adyacentes en la parte central del Mar Adriático (Mediterráneo central), uno impactado por actividad de pesca y otro no. Se estimaron la producción y la razón producción/biomasa (P/B) de 13 especies de crustáceos peracáridos y eucáridos mediante el método de frecuencia de tallas de Hynes. Las estimaciones para ambios sitios se compararon para probar la hipótesis de que los valores de producción y P/B deberían de ser mayores en la zona de pesca que en la zona de exclusión a la pesca. Los resultados indican que los efectos sobre las especies son más complejos que los esperados en relación a esta hipótesis, y que dependen de las características ecológicas y el comportamiento de las especies seleccionadas. |
