However, in some cases, recreational fishing takes more fish than commercial fishing, and in an increasing number of cases, recreational fishing is the main source of fishing mortality. In addition, current assessments indicate that some marine recreational fisheries have exceeded their quotas, raising concern because fishing effort in marine recreational fisheries is projected to increase.

Indeed, it is much more difficult to collect data on recreational saltwater anglers than on commercial fishing operations. There are far more saltwater anglers than commercial fishermen -- approximately 14 million anglers fished annually in recent years -- and they do not land their catches at specific points where there are dealers, as do commercial fishermen.

In response, the National Research Council (NRC) of the National Academies established the Committee on the Review of Recreational Fishing Survey Methods, composed of experts in survey design and statistics, biological statistics, fishery management, and the economics and sociology of recreational BOX B.1 Statement of Task This study will critically review the types of survey methods used to estimate catch per unit effort and effort in recreational fisheries, including state and federal cooperative programs.

CONCLUSIONS AND RECOMMENDATIONS General Conclusions • The committee agrees with conclusions of previous NRC committees that marine recreational fishing is a significant source of fishing mortal ity for many marine species and that adequate scientific information on the nature of that mortality in time and space is required for successful management of those species. • Marine fisheries management goals, objectives, and context have changed since the MRFSS was begun in 1979.

From page 147... ...
The for-hire sector of marine recreational fisheries should be considered a commercial sector, and survey methods and reporting requirements for that sector therefore should be different from those for private anglers. Sampling Issues Conclusions • The committee concludes that the current methods used in the MRFSS for sampling the universe of anglers and for determining their catch and effort are inadequate.
|
From page 148... ...
The lack of a universal sampling frame (registry or license requirement) for all saltwater anglers is a major impediment to the development of a reliable and accurate survey program.
|
From page 149... ...
• Additional studies are needed to understand the extent to which fish are kept and inspected, as well as the extent of catch not available for inspection to improve the accuracy of catch estimates. • Panel surveys, which contact individual anglers repeatedly over time, should be considered in recreational fishing surveys to gather angler trend data and to improve the efficiency of data collection.

From page 150... ...
Statistical Estimation Issues Conclusions • The designs, sampling strategies, and collection methods of recreational fishing surveys do not provide adequate data for management and policy decisions. Unknown biases in the estimators from these surveys arise from reliance on unverified assumptions.
|
From page 151... ...
To ensure adequate coverage of the recreational fishery, a periodic updat ing of lists and descriptions of fishing locations and access sites is needed. Human Dimensions Recommendations • An independent national trip and expenditure survey should be devel oped to support economic valuation studies, impact analyses, and other social and attitudinal studies.
|
From page 152... ...
Human dimensions expertise should be included as well. • Additional funding is needed for a survey office devoted to the man agement and implementation of marine recreational surveys, including coordination between surveys conducted in various state and federal agencies.
|
From page 153... ...
Many NRC and other reports stress the impor tance of using local and traditional knowledge, capacity building, and local communities in knowledge-gathering and dissemination activi ties. These recommendations apply, as well, to the recreational fishing community.
