Title: Domestic Longline System (DLS)
Status: In Work
Abstract:

This data set contains the individual carcass weights for swordfish, tunas, shards, and other species. Because of the market value of these species, each fish is individually weighed and recorded as the vessels are being unloaded. Vessels that have federal Highly Migratory Species (HMS) permits are required to submit the information from these sales receipts (tally sheets) to the Southeast Fisheries Science Center (SEFSC). This program began as a research project conducted by researchers associated with universities. In 1994, the National Marine Fisheries Service (NMFS) began to manage the collection and processing of these data.

Although swordfish are the primary commercial species caught and recorded individually on the sales receipts, the weights of other species were also listed on the tally sheets. Prior to 1985, the weight-out data for other (non-swordfish) species were not recorded. Beginning in 1986, the SEFSC began to enter the individual carcass weights for all species listed on the tally sheets.

The data in this data set include the following: a trip number [equal to the schedule number for the trip in the (Fisheries Logbook System)], a unique code for each vessel that lands these species and reports to the SEFSC, date of landing, state and port landed, code of the dealer purchasing the catch, gear fished, data source, location code of general fishing area, total hooks fished, days of actual fishing, total number of sets, and a species code along with the individual carcass weights for each species. All records from a specific trip are identified by their respective vessel codes, date of landing, and trip number.

Prior to 1986, effort (hooks, days fished, number of sets) information was recorded from personal vessel logbooks voluntarily submitted by vessel captain/owners. Beginning in 1986, all pelagic longline vessels that actively fished were required to submit daily logbook set records for each trip. Based upon this information that is stored within the FLS data sets, fishing effort is determined and subsequently added to the Domestic Longline Database on an annual basis.

Purpose:

There are two primary purposes for the implementation of this data collection program. The Domestic Longline Program was initiated to provide comprehensive landings data for swordfish. These data are needed to meet the commitment of the United States to the International Commission for the Conservation of Atlantic Tuna (ICCAT). Second, the program provides detailed, comprehensive size frequency and catch at size data for swordfish which support the stock assessments conducted by ICCAT scientists

Security Handling Description:

userid/password. Confidential data may only be released to entities having a signed non-disclosure agreement on file with the Director of the Information Resources Management Division (IRMD). Otherwise, confidentiality may be suppressed by the following methods used for aggregation of confidential data:

Data that are submitted as confidential can be released to the public under the following circumstances:

1. Combined or aggregated data. Confidential data can be released if the data are aggregated or summarized in a manner that prevents the identification of the person or organization that submitted the data. The "rule of three" and identification of majority allocations" are the primary data suppression methods.

2. Obscure (scramble) or remove the data identifier. For some types of data, confidential data Can be released as non-confidential if the identity of the person, vessel, company, etc. that submitted the data is not included or is scrambled as part of the data that are released.

3. Submitter. Confidential data collected under federal authority Can be released to the original entity (person, vessel, business, etc.) that sUbmitted the data.

4. Confidential data waived. The protection of confidential data can be waived by the person or business that submitted the data.

Lineage

Lineage Statement:

Prior to 1986, effort (hooks, days fished, number of sets) information was recorded from personal vessel logbooks voluntarily submitted by vessel captain/owners. Beginning in 1986, all pelagic longline vessels that actively fished were required to submit daily logbook set records for each trip. Based upon this information that is stored within the FLS data sets, fishing effort is determined and subsequently added to the Domestic Longline Database on an annual basis.
