Throw back the big ones. It's a new principle in managing commercial fishing, designed to save the lobsters (or fish) that lay the golden eggs.
Finally, some of the old, broken ideas are giving way. It used to be thought that a simple mathematical construct (maximum sustainable yield) was actually a good way to manage fishing. Only there were too many neglected factors that fell outside of the model and undermined it's utility. Things like the special reproductive value of big old fish (and lobsters) and the value of life history diversity in maximizing productivity.
Fishermen will now be required to throw back the biggest lobsters, following the lead of Maine. It's an overdue step and one that promises to help protect the future of lobsters and lobstering.
Maybe we'll see more efforts made to save the fish (and lobsters) that lay the golden eggs. Some fish (and lobsters) are too valuable to kill, they're worth more in the water than in the fish market.
