Oral Presentation III: Aquaculture and fisheries Ulfert Focken from Johann Heinrich von Thuenen-Institut opened the session where 3 participants presented their papers and moderated a quite lively discussion. Raymond Ouedraogo: Management of Fish Diversity in Lake Bam, Burkina Faso: Indigenous Knowledge and Implications for Conservation Raymond discussed that management of any type of resources particularly fish resources needs to account indigenous knowledge as it does have a distinct impact on its conservation. Further, he indicated that there are certain indigenous beliefs needs to be changed as these pushed for depletion of the fish stock. He even cites cases wherein people believe that “fish drop from sky and come from hills and caves” or that “authorities have to power to hide fish”. Furthermore, communal belief can be altered by institutions, education, religions, and economic change to push people towards the conservation their natural resources so not to push it to the brink of depletion. As of the moment, there are actions emanating from the grass roots level to provide conservation efforts like creating mini-dams and planting trees to fully delineate Lake Bam. Vikas Kumar: Kernel Meal from a New Non-toxic Jathropa Species – Jathropa platyphylla – as a protein source for Nile Tilapia (Oreochromis niloticus) Diet Vikas presented his findings wherein he uses a specific type Jathropa species and its deflated kernel meal, containing 60% to 66% of crude protein, as a fish meal. He test this fish meal to 15 male fish at different diet providing a control having a commercially-available fish meal based protein, Jathropha meal wherein 62.5% fish meal protein contains the latter, and soybean meal which also have 62.5% fish meal protein. Thus, he concludes that fish fed with the Jatropha platyphylla deflated kernel meal shows better growth performance and nutrient utilization as compared to other fish meals. Since, Nile Tilapia could efficiently utilize the Jatropha meal as the source protein then this resilient shrub can provide real opportunities as a new feed source. Julia Jantke: How fishing communities on the on the Sangihe Islands, Indonesia struggle to maintain their traditional livelihood while adapting to the modernization of fisheries. Julia noted that the Sangihe Islands are small island group on the northern tip of Indonesia. Based on her research, there exists a strong interaction on the fishery sector as reflected on the established social networks. Since, community´s internal dynamics are simultaneously influenced by a number of external variables gradually changing the whole society. These external variables are climatic influences and socio-economic changes which directly affects the communities fishing possibilities. Furthermore, these variables currently and continually shape people´s incentives and communal attributes as reflected by traditional fishing communities such as the ones in Sangihe Island.
