Stima della Pescosità Potenziale Attraverso l'uso di Specie Indicatrici
Abstract

In order to assess the fishery potential of the Aquatina lake we applied the method of VATOVA (1953) which relates the quality and quantity of the benthic macrofauna with the maximum sustainable yield in fish. Samples of benthic macrofauna were taken in October 2006 and November 2007. The forthcoming data revealed that the fishery potential was 16 kg/ha in 2006 and 36 kg/ha in 2007, consisting in 60% of seabass, seabream and eel and 40% grey mullet. According to the bionomic scheme of FRISONI et al. (1984), 80% of Aquatina basin falls within Zone III and Zone IV.
