| Abstract | The study of fish populations in reservoirs is essential for sustainable management of the freshwater fisheries. The sampling technique used was based on the European standard CEN prEN 14757. This technique (multi-mesh gillnets) was adapted to Tunisian dams. A stratified random sampling was implemented according to the depth and area of the dam. Samplings were conducted in Sidi Salem reservoir between April and May 2014. The fish communities were composed by 7 species: roach, rudd, carp, pike-perch, phoxinel and two species of mullet (Liza ramada and Mugil cephalus). The weight and numeric yield was average (114 ind / 1000m2 and 8.08Kg / 1000m). The majority of catches were obtained at depths less than 12m. Populations of Mullet and carp show a strong deficit indicating a state of over-exploitation and insufficiency of stocking. Sidi Salem reservoir has a well balanced and abundant population of roach, rudd and pike-perch. However, this dam presents a remarkable deficiency of autochthon fish. Diversity indices indicate a little diversity in this dam. Additionally, we identified that the stock of mullet was declining and of eels was lack in this survey. This reservoir required a support from fisheries managers. |
