developed an innovative mail survey design through an enhanced sampling frame to improve effectiveness and appropriateness of fishing effort estimation for the Marine Recreational Information Program (MRIP)

The Coastal Household Telephone Survey The original fishing effort study, the Coastal Household Telephone Survey (CHTS) , was a telephone survey conducted on a targeted random sample drawn from a list-assisted, landline RDD sampling frame.

Although the ALDS response rates were only "marginally higher" than those for the CHTS, the new sampling frame resulted in significant data-collection efficiencies through an increased number of interviews from the target population of saltwater anglers (Andrews et al., 2014)

, but NMFS noted that the remaining undercoverage could limit the quality of the fishing effort estimates. Additionally, the general, ongoing decline of response rates to telephone surveys was a growing challenge.
|
From page 50... ...
The 2006 report recommended that a dual-frame survey (i.e., using more than one sampling frame to draw a probability sample) "should be used wherever possible to reduce sample bias" associated with undercoverage noted for the single sampling frame design (see Chapter 2 discussion)
|
From page 51... ...
Disadvantages include mode effects (differential patterns of reported information associated with the datacollection methods) , lower data quality (Sakshaug et al., 2010)
|
From page 52... ...
Because the MRIP's scope covers recreational angler fishing effort regardless of where the person lives, both the CHTS and FES may include some level of undercoverage in the fishing effort estimates if the adjustment for noncoastal anglers estimated from the Access Point Angler Intercept Survey (APAIS) is somehow insufficient (Fisheries Statistics Division, 2016)

From page 53... ...
to evaluate changes in the short CHTS instrument to improve, for example, the angler's ability to report on saltwater fishing sites to the exclusion of freshwater sites. NMFS also focused on telescoping errors where respondents inadvertently include or exclude fishing trips from the designated 2-month reporting period (Gaskell et al., 2000)

. The FES sample design, by contrast, is a stratified simple random sample selected bimonthly from an ABS frame of addresses in Atlantic and Gulf Coast states.

no greater than 20 percent and historical response rates (Fisheries Statistics Division, 2016)
|
From page 56... ...
As noted previously, the FES ABS frame appears to contain only information appended from the NSAR and no other source. NMFS may find that a nonresponse model enhanced with NSAR information could prove of benefit for the matched sample if item nonresponse and data quality were sufficient to warrant investigation.
|
From page 57... ...
Consider this generic example: Unbeknownst to the research team, the FES sampling frame had 25 percent undercoverage of the angler population, a conservative estimate given the 70 percent result cited in Andrews et al.

From page 58... ...
. NMFS has made great strides in redesigning the effort survey to lower bias and improve data quality.

From page 59... ...
. CONCLUSIONS AND RECOMMENDATIONS Conclusion: The methodologies associated with the current Fishing Effort Survey, including the address-based sampling mail survey design, are major improvements over the original Coastal Household Telephone Survey that employed random-digit dialing to contact anglers.
|
From page 60... ...
Recommendation: As recommended in the 2006 report, NMFS is encouraged to continue research on survey panels, where a portion of the sampled households is retained for one or more interviews, for the Fishing Effort Survey alone or for an effort-catch combined study. The purpose of the survey panel would be to assess trends and any anomalies in those trends, to assess any improvements in data-collection efficiency through increased participation, and possibly to lower measurement error associated with, for example, trip recall with a more engaged sample of anglers.
|
From page 61... ...
Consequently, the use of additional variables that are associated with fishing effort and/or survey participation might prove beneficial for the weight adjustment models. Recommendation: Current or augmented variables on the address-based sampling frame should be evaluated to improve the efficiency of the Fishing Effort Survey weighting methodology.
