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.
