Ecophysiology of selected aquaculture species in Indonesia and the Philippines

StressChron Framework:

Project code 088
Role Coordinator
Research area Contributing to a more sustainable and animal welfare minded food production
Research topic Improving sustainability and animal welfare in aquaculture and husbandry
Vertebrate Fish
Species Milkfish (Chanos chanos)


The research goal is on stress evaluation of cultured fish in Indonesia and the Philippines, in particular on milkfish (Chanos chanos), and includes the identification of potential stressors, the assessment of metabolic performances of fish under the influence of certain stressors and the search for indications of chronic stress. Furthermore, the project focuses on strategies to minimize or “re-use” excessively nutrient outputs from aquaculture systems with an integrated multi-trophic aquaculture (IMTA) approach by combining cultures of nutrient releasing organisms with cultures of filter feeding/ nutrient up-taking organisms.
