I don't think anyone that has replied in this thread (please forgive me if anyone has written their thesis on this..

) can say for sure that fish (especially the fish that most of us keep - not sharks!) do not eat steady in the wild.
I will give you my uneducated opinion on this - I believe that fish eat fairly steady, at most opportunities... especially africans that graze on the algae and biofilm in the rift lakes, they are eating all the time, and food is available all the time.
My support of this belief is that any fish that I have caught fishing and consumed has had something in its stomach, whether it be insects, crustaceans, or other fish...
