MRIP collects information from recreational anglers about how often they're going fishing (effort) and what they're catching per trip (catch rate) using a system of surveys. Many of our surveys are conducted year-round and involve interviews with thousands of anglers. Information from our surveys is combined with other sources of data like commercial catch, biological research, and direct observation of what's happening in the fishery to inform management decisions.
Since it's impossible to count every angler or observe every fishing trip, we rely upon statistical sampling to estimate the number of trips recreational fishermen are taking and what they are catching. This method – similar to what’s used in opinion polling or TV ratings – gives us an estimate about the number of trips recreational fishermen are taking and what they’re catching on those trips.
