Fish species cultivated were tilapia (Oreochromis
niloticus) during aubergine production
in 2004 and eurasian perch (Perca fluviatilis) in
the later experiments with tomato and cucumber.
Tilapia was a natural strain imported from Lake
Turkana, Kenya, perch was obtained from Percitech
S.A., a Swiss company specialized in perch
breeding. The fish were fed ad libitum with a
swimming pelleted feed (Trouvit Tilapia Starter,
3.5mm, 45% raw protein).
