Title and Description:

Methodology for Sampling and Estimating Bycatch of the Hawaii Deep-Set Longline Fishery

Quantifying bycatch in the Hawaii deep-set longline fishery is required by the Magnuson-Stevens Fishery Conservation and Management Act (MSA), Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), and Migratory Bird Treaty Act (MBTA) and their implementing regulations. As over a hundred species, some of them listed as endangered or threatened, have been recorded as being caught in the Hawaii deep-set longline fishery, reliable bycatch estimates need to be computed in a relatively quick manner on a yearly basis. Since mid-year 2002, a unique complex sampling design has been used to select deep-set longline trips for observer placement. While onboard a selected longline trip, NMFS-trained observers collect information on bycatch and ancillary variables for each longline fishing operation. Based on the sampling design, bycatch estimates are computed for all species of marine mammals, protected species, sharks, and other fish that have been observed at least once in the fishery or are of special interest. What estimators are used depends on the observed frequency distribution of bycatch events for the species of interest. Interval estimators have been developed for commonly, seldom, and very rarely bycaught species. Methods for estimating bycatch within specified geographical subareas of the fishing grounds and the total number of marine mammal bycatch events resulting in a death or serious injury (DSI) have also been developed as the MMPA requires estimates of DSI within and outside the Exclusive Economic Zone (EEZ) of the United States.

These annual bycatch estimates of sea turtles, seabirds, and marine mammals are used to monitor takes within the deep-set longline fishery. These estimates have a large potential impact on endangered species and the valuable longline commercial fishery in Hawaii. Additionally, bycatch estimates of all species are provided for inclusion in the National Bycatch Report, seabird and sea turtle estimates are submitted annually to the IATTC (Inter-American Tropical Tuna Commission) per Resolution C-11-02 and C-04-05, and marine mammal, seabird, and sea turtle estimates are provided for inclusion in the annual WCPFC (Western and Central Pacific Fisheries Commission) National report.

Peer reviewers will be designated by an outside agency, Center for Independent Experts.

Will the public, including scientific or professional societies, be asked to nominate potential peer reviewers? no

Will there be opportunities for the public to comment on the work product to be peer reviewed? no

How and When? The CIE review was an official public meeting with notice given in the Federal Register. There was time allotted to allow public comment at the review.

Will the agency provide significant and relevant public comments to the peer reviewers before they conduct their review? NA.

Primary disciplines or expertise needed in the review: Reviewers should be Statisticians with comprehensive knowledge of both theoretical and applied sampling design and analysis. Furthermore, reviewers should have some knowledge of analyzing rare events, bootstrap techniques for finite population sampling, and frequentist and Bayesian inference for finite populations. Experience in statistics related to natural resources is beneficial.
