How much fish is too much?

IMO this 'rule' is highly inaccurate. A better parameter for gauging bioload is fish mass, not the length. Since a fish's bodymass can increase tenfold with a doubling of length (the fish will also be wider and taller in addition to longer), that rule of thumb gets really inaccurate with larger fish.

Also keep the fish's shape in mind. A long narrow fish like a trumpet/coronet is not going to have as large of bioload as, say, a fat grouper of equivalent length.
