Effects of Omega 3 depletion on marine fish: ecophysiological approach

There is increasing evidence that climate change might critically deplete nutrients in food web of marine fish. In particular, a reduction in the production of Omega 3 (Ω3) in phytoplankton as a result of ocean warming can have negative impact on fish. Ω3 are fatty acids that are essential components of cell membranes. Such depletion in Ω3 in membranes can impair fish performance, however, the underlying mechanisms remain obscure. Mitochondria are likely to be involved in the fish response to Ω3 depletion. Changes in the composition of membrane fatty acid of mitochondria affect their efficiency. Organisms that have less efficient mitochondria are less able to maintain ATP [Adenosine TriPhosphate) production, a feature that is likely to affect the overall animal performance. This PhD work will therefore evaluate how the reduction in dietary Ω3 affect mitochondrial function and in turn the performance of a fish, the mullet (Liza aurata)
