If a saltwater angler goes out on a boat, how much could we expect that person to catch during a typical day? I would like to set some personal expectations.
Obviously if the variables are against you (eg: bad spot), the lower bound would be 0. But if you get it right (see the linked question What are the variables that will significantly affect saltwater fishing success?), what is a good, or maybe upper bound, that we can expect?
If we have an estimate based on good anglers (eg: records or sports champions), that would help us know what not to expect, which is useful, and I suspect that info might be easier to come by, but all I can find is records for the largest fish caught, which really is not helpful here.
Since I fish to eat, I am interested in total weight, so I don't really care if it is a single 20 pound fish or 20 single-pound fish. If that information is not available, then whatever info is available is acceptable as long as it is useful for me to make estimates to set my expectations.
It doesn't need to be exact at all; very rough estimates are fine as long as they are useful. If location matters, assume Atlantic ocean, off the eastern coast of the United States of America.
