Eating and feeding

We got to feed to trout and some baby prawns - very weird feeling with those little guys hungrily clawing at your arms. The really little ones eat scrambled eggs and mussels, the bigger guys eat fish food (I shudder to thing what's in those pellets). Then we got to eat their older cousins and aunties who were fed by other tourists a few months back. Pretty weird really. These guys started with 5o prawns and a barbie. By one year they had 150 000 prawns. They are now also filthy rich and sell about 36 tons of prawns a year. Anyone want to start a prawn farm with me in Africa?
