Five-year extension of the moratorium on perch fishing at Lake Saint-Pierre
What are the factors that slow down the recovery of Yellow Perch in Lake Saint-Pierre?
Recovery is slowed by a combination of factors:

Loss of breeding habitat in the floodplain;
Poor water quality of streams flowing into the lake;
Deterioration of aquatic grass beds;
Arrival of competing species;
Predation of young yellow perch by double-crested cormorant.

In the US there have been a few moratoriums for fishing of certain species. The striped bass are recovering strongly after a moratorium on catching them. �John P. Wiley, Jr., Smithsonian, November 1993. Usually the regulatory agencies first reduce the daily bag / catch limit to allow the population to recover or increase which is usually successful because most threatened and declining populations are due to overharvest especially those open to public harvest.

After Paul Prudhomme created the Blackened Redfish craze, the formerly overlooked species was commercially fished almost to extinction in the coastal waters of Louisiana. Finally it was given game fish status, thus halting commercial fishing. Nowadays redfish are doing fine.

By the way, if cormorants are an issue, I think shotguns are in order.
