This project wants to investigate the ecological role of the Patagonian squid\u00a0Doryteuthis gahi\u00a0<\/em>(known as\u00a0Loligo gahi)<\/em>\u00a0within the waters of the Falkland Islands. There are three main aspects of this project. First is to investigate the diet of\u00a0D. gahi<\/em>\u00a0by analysing stomach content analysis, revealing the foraging spectrum, the food consumption and feeding strategies and behaviour. Second aspect is the trophic position of the Loligo squid. This will be investigated by measuring Stable Isotope rations of carbon and nitrogen of\u00a0D. gahi<\/em>\u00a0individuals of all available size classes in five areas around the Falkland Islands and in all seasons of one year. Muscle tissue will be measured to gain a short term signal of the trophic position; Gladii-parts of the squid will be measured to detect ontogenetic changes within a lifespan of an individual. To link the trophic position of the squid to the ecosystem, important commercial species and ecological related species of\u00a0D. gahi<\/em>\u00a0will also be analysed with Stable Isotope measurements. Last aspect is to build an ecosystem model of the Falkland Island waters with the freeware \u2018Ecopath with Ecosim\u2019, which will allow tracing energy flows within the ecosystem and make future predictions of biomass changes. \u00a0<\/p>\n\n\n\n

This project falls into objective #3 of the FIG-FD, as it will give insights in the biology and ecology of one of the commercially most important species of the Falkland Islands, the Patagonian squid\u00a0Doryteuthis gahi<\/em>.\u00a0 By investigating the diet and trophic position of the squid and giving an ecological context by comparing it with other important species of the Falkland Island ecosystem can help to manage and maintain the Falkland Islands fishing grounds. An ecosystem based model can also support the ongoing stock assessment procedures.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
