We consider monitoring populations of naturally reproducing sport fishes the first priority. Management is not an exact science. Normally fluctuating environmental factors affecting the growth and survival of fish are outside the control of resource managers. Because of natural fluctuations in the abundance of fishes, changes in angling effort and effectiveness, and the application and effect of different management strategies, monitoring populations of sport fish is an ongoing effort for effective managers. Populations of naturally reproducing fish often cannot withstand intense recreational fisheries, even when severe constraints are placed on methods of fishing and harvest.
Intense fisheries occur in urban areas or on the roadside waters nearby.
We have developed and implemented a statewide stocking plan to maintain angling opportunity in these intensively fished waters. The plan establishes the fishery location as well as the species and numbers of fish that will be reared and released to enhance these fisheries. Fish are produced at three hatcheries operated by the division as well as other facilities in the state we contract to produce fish intended to benefit sport fisheries. Divisional personnel both manage the harvest of these fish and evaluate the effectiveness of enhancement. Programs and hatchery practices are continually modified to optimize the success and efficiency of this work.
