Perhaps. In Nordic countries the sheer abundance of lakes and ponds lead to somewhat similar things.

"Biomass overgrowth of lakes and annual blue-green algae bloom as a result of eutrophication has reduced the overall use of water resources as seen from a point of recreational and leisure use. Also fish stocks have changed so that less valuable fish dominate at the cost of valuable fish like salmon and trout. Selective fishing is an effective way to reduce the overgrowth of less valuable fish populations and at the same time reduce eutrophication of water bodies." http://www.hoitokalastus.com/hoitokalastus_en.html

I.e. they require certain amount of fishing to remain useful in that regard.
