The shrimp fishery (Farfantepenaeus subtilis and F. brasiliensis) was the first fishery in value in French Guiana during the 1990s. However, two successive drops in recruitment in 1999 and 2006 led to decreases in stock and hence landings of shrimp. Recruitment levels are today at their lowest. Prior analyses suggest a minor influence of harvesting and fish predation on the failure in stock rebuilding. Environment instead appears to play a pivotal role here. In a region where few oceanographic surveys have been carried out, remote sensing has proven a powerful tool to track variations in the environment. Series of water temperature, turbidity, suspended matters and chlorophyll a concentrations were analysed and compared to the series of shrimp recruitment... |

The demersal trawl fishery of the north Tunisian coast primarily targets the deep-water rose shrimp, Parapenaeus longirostris, and secondarily a variety of demersal fish species. These fishes include hake (Merluccius merluccius), common pandora (Pagellus erythrinus), red mullet (Mullus barbatus), surmullet (Mullus surmuletus), Atlantic horse mackerel (Trachurus trachurus), bogue (Boops boops), picarel (Spicara smaris) and spotted flounder (Citharus linguatula). A bioeconomic model was used to test management measures through scenarios that ran over eleven years to estimate the viability of the fishery according to biological and economic results. The most beneficial scenario was the combination of several management measures including a temporal closure of... |
