With the aim of determining and evaluating the condition of freshwater fisheries in Tunisia, 14 surveys were undertaken in the most important reservoirs of the country. Specimen were collected between May 2013 and May 2016. The sampling areas are Bakbeka, Bir Mcherga, Bouheurtma, Bezirekh, Ghezela, Kasseb, Laabid, Lahjar, Mellegue, Mlaabi, Sidi Barrak, Sidi Saad, Sidi Salem, Seliana and they vary in depth and surface areas. For fish sampling in lakes, we used multi-mesh gill nets made for the purpose. We applied standard fishing methods to investigate biomass, species composition, size distribution and abundance. Eight species were caught in the prospected reservoirs: Liza ramada, Mugil cephalus, Luciobarbus callensis, Sander lucioperca, Rutilus rutilus, Cyprinus carpio, Scardinius erythrophthalmus and Pseudophoxinus callensis. |
