Aquakultur in den Philippinen

Dieser Text ist zur Zeit nur auf Englisch verfügbar...

The majority of the world's aquaculture produced fish are from Asian countries where aquaculture facilities are often characterized by the heavy use of chemicals, antibiotics, overfeeding, and little environmental awareness and control. In particular, open fish cage farms cause dramatic increase in nutrients in surrounding ecosystems.
This, in turn, results in areas adjacent to fish farms typically being characterized by high bacterial abundances, high concentrations of chlorophyll and organic-matter-rich particles. Additionally, the rapid sinking of aggregated labile organic matter originating from aquacultures to the sea floor often leads to hypoxia and the loss of biodiversity and its ecosystem services.

Currently, there is an urgent need to investigate aquaculture practices as well as their ecological impact and social and economic backgrounds in order to design and improve the present aquaculture technology and increase sustainability and food safety.
 
The overall project goal, separated in four working packages is to examine the impacts of aquaculture effluents on 1) ambient microbial community structure, particularly distribution and spread of pathogens and antibiotic resistance genes, 2) organic particle transportation and sedimentation rates of labile organic matter, 3) metabolic performance of cultured fish stock, and 4) a detailed investigation on human dimensions and stakeholder decisions towards aquaculture practices. Ultimately, these studies will enable predictions of ecosystem resilience and responses to environmental perturbations and provide management recommendations towards securing sustainable food resources.
