Hello,

I am very interested to hear that others are using delta carbon to assess
the contribution of manure and autotrophic and heterotrophic pathways to
fish growth in aquaculture. I am working on silver perch (Bidyanus
bidyanus) in Australia and I am examining the sources of carbon in fish
supplied directly with manure, or fed natural prey (zooplankton and
chironomid larvae) that have been cultured using manures.

I would be very happy to hear directly from others involved in similar
research who can perhaps direct me to recent research papers (preferably in English).

Regards,
Deb.
