“…The present work has shown that the eco-biological conditions are favorable for the growth of Chelon ramada in Siliana Reservoir compared to other freshwater reservoirs in Tunisia. 3,40 Besides, the fishing mortality rate is higher in Siliana compared to Kasseb Reservoir.…”

Mullet is the most massively harvested species, representing the third of the total freshwater fish landing in Tunisia. To ensure freshwater fish farming durability and development in the country, reservoirs have been stocked with Mugilidae fry which was collected from coastal and estuaries areas after a short adaptation period. The objective of this paper is to compare and contrast Chelon ramada’’s age, growth, and mortality in two Tunisian freshwater reservoirs (Seliana and Kasseb). The sample species were caught with a multi-mesh gillnets and were classified into five age groups. The study of the age and growth demonstrated variability between Chelon ramada species’ features. The optimal size of the captured mullet (Lopt) was equal to 37.62 cm for M=0.48, L∞=57.05 and K=0.31 in Siliana Reservoir. Whereas, it measured 31.42cm in Kasseb Reservoir, for M=0.795, L∞=48.15 and K=0.31. It has also been found that the fishing mortality rate is very high at Siliana Reservoir when compared to Kasseb Reservoir. This work is a contribution to the identification of the biological features of Chelon ramada that lives in Siliana and Kasseb Reservoirs. It seeks to ensure a rational and sustainable exploitation of fishery resources in these Tunisian freshwater reservoirs and it recommends the development and preservation of mullet fisheries.

“…This reservoir has a surface area of 1700 ha, and a mean depth of 30m (Figure 1). The fish community in this reservoir is composed by carp (Cyprinus carpio communis), mullets (Mugil cephalus and Chelon ramada), catfish (Silurus glanis), barbel (Barbus callensis) and eel (Anguilla anguilla) with an annual yield of 511.14 T. 3,14 Socioeconomic data: The economic and social study is based on data obtained from interviews with fishermen. These interviews were carried out during the period from January 2007 to December 2008.…”

“…Therefore, in the 1990s, within the framework of the Tunisian-German cooperation project, introduction of new species was initiated, including the introduction of non-native carp, pikeperch, Rudd, roach, black bass and the continued stocking of mullets. [1][2][3] Currently, 33 reservoirs and lakes are involved in this type of activity. These artificial lakes are widely used as aquaculture sites where juvenile mullet are regularly released to promote fishing.…”

“…[6][7][8][9] The main species exploited in the Tunisian reservoirs are carp Cyprinus carpio, barbel Barbus callensis, roach Rutilus rubilio, rudd Scardinius erythrophthalmus, catfish Silurus glanis, eel Anguilla Anguilla, mullet (Mugil cephalus and Chelon ramada) and pikeperch Sander lucioperca. [1][2][3][10][11][12] Production in Tunisian reservoirs increased from 831.5 tons in 2000 to more than 1073.194 tons in 2020, of which 37.6 % came from the reservoir of Sidi Saad. 3,9,13,14 On the other hand, extensive inland fish farming offers to fishermen the opportunity to profitably production of fish species.…”

This paper analysis of the socio-economic situation of the fishing activity in Sidi Saad reservoir in order to estimate the real production of fishing in this dam, to determine the demographic structure of the fishermen and to provide information on the profitability of this fishing activity.The results of this study indicate that the fishermen operating in this reservoir are young (average 39 years), with an education level reached limited to primary school (64%) associated to a low monthly income (do not reach the minimum wage). Estimated fishing productions from the survey made in 2 successive years are higher than those indicated in the statistics of the fisheries administration (95 tons against a declared production of 62 tons in 2007 and 112 tons against 72 tons in 2008). In addition, the socio-economic investigation showed that the majority of fishermen practice a second activity in addition to fishing (61%).Continuous scientific monitoring of the fishing in this reservoir is necessary for the sustainability of this activity and to fix the populations of fishermen in their village.
