I went electrofishing at school and you get something like a battery strapped to your back go into the stream or river. It was fun. The fish go belly up from the pulse but their not hurt, just stunned. Then you measure and weigh them, see the species and let them go. In all we caught
Yellow bottom feeding fish ( censored word makes it funny....)
ummm...hmm can't remember the rest...but one brook stickleback had a tumour on its stomach which was kind of nasty.
I also had to dissect a fish once...not nice smelling.
My favourite 'fish' is
or the great white shark. So under appreciated by society its sad.Carcharodon carcharias
