Abstract

There is a growing need to evaluate how fishing activities is being affecting the ecosystem. The thesis seeks to frame the assessment of risk status of three main fisheries operating in the Algerian coastal ecosystem, which are trawl, purse seine, and small-scale fisheries. The ecosystem-based fisheries assessment was developed by (Zhang, et al., 2009) have been suggested to conduct the present study. Tier 2 process analysis has been used, since the qualitative data was not rich. Across the nested risk design, the trawl, purse seine, and small-scale fisheries risk indices were projected in the yellow zone. The highest FRI were observed in trawl fishery (1.363), followed by the small-scale fishery (1.309), then the lowest value was found in the purse seine fisheries (1.114). The purse seine fishery risk index differed significantly from both of trawl and small-scale fisheries risk indices, whereas there was no significant difference between trawl fishery risk index and small-scale fishery risk index. A proper management measures were to improve the fisheries risk situations.
