“…The total number of individuals and the annual somatic produc- tion of D. trunculus were lower at Sidi Salem than at Echatt. This seems to be consistent with the proximity of Sidi Salem to the Seybouse River, the industrial Port of Annaba, and the relatively low hydrodynamic conditions at this site, which may favor the accumulation of pollutants (Abdennour et al, 2000;Djabri et al, 2003;Belabed et al, 2013). Differences in the condition index (CI) of D. trunculus, found to be slightly higher at Sidi Salem than at Echatt, may also be related to oil exposure of clams at Sidi Salem, rather than to variations in individual biomass between the two study sites.…”

“…One site was the beach of Sidi Salem (36°50'N -7°47'E) characterized by slow vortices and relatively low hydrodynamic conditions (LCHF, 1976). This site is located to the east of the Seybouse River which carries domestic and agricultural pollutants, such as untreated sewage, fertilizers and pesticides (Abdennour et al, 2000;Djabri et al, 2003;Belabed et al, 2013). In addition, the proximity of Sidi Salem to the Port of Annaba (the second largest industrial port in the country) may contribute to the accumulation of other pollutants, such as sewers and hydrocarbons, in the area (Djabri et al, 2003).…”

At Sidi Salem, collection of D. trunculus is prohibited by law and is very sporadic because of pollution, thus clam exploitation has little relevance here.…”

The population dynamics and secondary production of the wedge clam Donax trunculus were studied in the Gulf of Annaba (Northeast Algeria) monthly for one year at a site close to the Annaba port and the Seybouse river, affected by industrial and agricultural pollution (Sidi Salem), and at a site more distant from major pollution sources, but exploited by fishery (Echatt). The number of individuals (N) was lower at Sidi Salem (36–148 ind m-2) than at Echatt (63–272 ind m-2) in most sampling dates, while the biomass was more variable from one date to another, with no consistent pattern of differences between sites. The condition index (CI), although slightly higher at Sidi Salem than at Echatt, showed at both sites a major increase in March/April, June/July and October, reflecting two main periods of gonads development and increase in the level of stored reserves at the end of the reproductive period. Consistently, the recruitment of D. trunculus ran from April to October with a major peak of abundance in spring and a minor one in early fall. The maximum age of D. trunculus was 3 years and the growth rate was highest in the first year. Annual somatic production (P) was lower at Sidi Salem (0.773 g AFDM m-2 yr-1) than at Echatt (1.262 g AFDM m-2 yr-1), possibly reflecting a lower mean annual biomass at Sidi Salem (1.642 AFDM m-2) than at Echatt (3.046 AFDM m-2), while the annual P/B ratio was similar between the two sites (i.e. 0.471 and 0.414 yr-1, respectively). Lower N and P at Sidi Salem compared to Echatt are consistent with the proximity of Sidi Salem to the industrial port of Annaba and low hydrodynamic conditions which may favor the accumulation of pollutants, such as hydrocarbons. On the other hand, moderate secondary production of D. trunculus at Echatt compared to other Mediterranean sites may be due to excessive harvesting. We suggest that the low secondary production described in this study should be taken into account for the development of sustainable strategies of clam exploitation in the Gulf of Annaba. In particular, effort should be made to reduce land-based pollution and to regulate the collection of D. trunculus according to the life cycle and production potential of this species.

“…Agricultural and industrial activities present in the study area developed several forms of surface water pollution. The population in of Guelma increased during two decades from 77,821 to 157,334 inhabitants, sewage of agglomerations is discharged directly in the Seybouse River without preliminary treatment (Djabri et al 2003). In the region of Guelma, ceramic and agro industry factories discharge waste waters in the Seybouse River, other sources of pollution come from petrol stations distributed throughout the region.…”

The assessment of water quality has been carried out to determine the concentrations of different ions present in the surface waters. The Seybouse River constitutes a dump of industrial and domestic rejections which contribute to the degradation of water quality. A total of 48 surface water samples were collected from different stations. The first objective of this study is the use of water quality index (WQI) to evaluate the state of the water in this river. The second aim is to calculate the parameters of the quality of water destined for irrigation such as sodium adsorption ratio, sodium percentage, and residual sodium carbonate. A high mineralization and high concentration of major chemical elements and nutrients indicate inevitably a high value of WQI index. The mean value of electrical conductivity is about 945.25 ls/cm in the station 2 (Bouhamdane) and exceeds 1,400 ls/cm in station 12 of Nador. The concentration of sulfates is above 250 mg/l in the stations 8 (Zimba) and 11 (Helia). A concentration of orthophosphate over 2 mg/l was observed in the station 11. The comparison of the obtained and the WHO standards indicates a before using it use in agricultural purposes.

Water is seen as key factor for development. Its scarcity raises concerns at all scales. In regards to water resources, Annaba and El-Taref are intimately connected, the different activities (groundwater and superficial), focused on increasing supply, have been considered as a response to water demand.The actual system use of water resources is not able to sustain water needs that are more and more growing in different expansion sectors. Consequently, a strategy should therefore be sought to integrate the various sectoral needs in available water resources in order to reach the economic and ecological sustainability. We will try to respond to this problem by use of Water Evaluation and Planning (WEAP) model. This study is the first attempt to estimate water demand and analysis of multiple and competing uses of hydro-system in Seybouse's Wadi basin and to make comparison with proposed water storage estimates. This model was applied according to five different scenarios which reflect the best and worst conditions of the supply and demand, not only to evaluate water demand deficit, but also to help planners to the alternative management.The model stimulation showed that the area study is sensitive to a serious water scarcity by 2030. It is possible to observe an improvement with integration of other management strategies for a best operating system.
