Undercoverage arises when some population units exist but are not linked to the frame and therefore have no probability of being sampled e. A source of potential bias in the estimate of effort is due to the proportion of private anglers who are not part of the sampling frame.

In the context of site access, an area frame would be a coastline map that could be sampled in portions, and each portion would be searched for access sites. Furthermore, the target species for anglers may be varied and may include species entirely allocated to recreational fisheries, as well as those from mixed recreational and commercial fisheries.

Additional ILINet data, including national, regional, and select state-level data for the current and previous seasons, can be found at http: Influenza surveillance in the U. This frame suffers from overcoverage since not all households contain anglers, undercoverage since some anglers do not live in coastal counties or live in coastal counties but have no landline telephones, and duplications since some anglers live in households with more than one working landline.

This sample design is selected to improve the efficiency of the CPUE estimate and seems likely to do so if the pressure matrix effort estimates are accurate. Page 56 Share Cite Suggested Citation: Nationally, the percentage of respiratory specimens testing positive for influenza viruses in clinical laboratories during the week ending May 19 was 2.

They may result from low precision in the estimate which can be corrected by increasing the sample size or sampling efficiency so that the estimate may be unbiased but may vary from the true parameter value in any given period because of expected variation.

Validation of charter boat records is recognized as an important component and source of error information for the estimation process. Additional data, including data for previous seasons, can be found at https: During most seasons, adults 65 years and older have the highest hospitalization rates, followed by children years.

Records of client participation are kept to varying levels of resolution.

Similarly, reliance on dock-side intercept surveys alone is susceptible to problems of incomplete spatial sampling frames see Box 2. These records provide two capabilities: Influenza A H3 viruses have predominated this season. The problem with achieving these goals is that the nature of recreational fishing does not allow for data to be collected for all anglers.

An angler fishing from a private residence might never be subject to an intercept interview, and therefore, his or her data never could contribute to CPUE estimate.

Not knowing whether the adjustments introduce bias, and not being able to test for this bias, creates uncertainty about the quality of the estimates. It is important to create a rigorous and objective sampling protocol for validations of this type.The situation is all the more sensitive as, due to current restrictions on the number of visitors, [ ] the 20, visitors per year fall far short of the anticipatedper year.
