It's happening right now.
There is very strong empirical data that fish populations have been now decimated so badly that it will be hard to intervene and alter the decline in many of the most popular (and necessary) species.
Blue fin tuna is nearly extinct. Cod is decimated. Salmon are in decline. Garden variety tuna stocks are also in steep decline.
