Abstract:

This dataset contains data on landings, value and trips provided by the Louisiana Department of Wildlife and Fisheries Trip Ticket Program. The data are available for five species groups (blue crab, freshwater fish, oysters, saltwater fish, and shrimp) aggregated at various levels (species, basin, gear, and month/year), depending on the level that would ensure confidentiality.

Purpose:

The data were obtained in order to estimate the impact of the Deepwater Horizon spill on commercial fisheries in Louisiana.

Data Parameters and Units:

Type (blue crab, freshwater fish, oysters, saltwater fish, and shrimp); Basin; Year (yyyy); Gear (a type of gear used); Month (mm); Landings (pounds); Value (dollars); Trips (number). All Landings are in whole weight; Oysters are meat weight.

Methods:

The data are aggregated into the 4 tiers following these rules: Tier 1: Data provided at the species/year/month/basin/gear level for any cells that are non-confidential. Tier 2: All species/year/month/basin/gear cells that are confidential at the Tier 1 level are aggregated to species/year/month/basin. Data are provided for non-confidential cells at this level. Tier 3: All species/year/month/basin cells that are confidential at the Tier 2 level are aggregated to species/year/month. Data are provided for non-confidential cells at this level. Tier 4: All species/year/month cells that are confidential at the Tier 3 level are aggregated to species/year. Data are provided for non-confidential cells at this level. Note that trips may be duplicated across species types because multiple species can be recorded on a single ticket (for both paper and electronic trip tickets). In addition, the disaggregation by gear and basin can cause duplication in the trip count for electronic trip tickets, as multiple gears and areas fished can be reported on an electronic trip ticket.
