Anglers are required to report all recreationally caught Atlantic bluefin tuna, billfish, and swordfish to NMFS, provided the landings are not affiliated with a registered tournament. Reports are filed via an internet website or an interactive voice recording system. The data are stored in the ALRS. Data elements collected include species landed, date of landing, date of fishing trip, port of landing, vessel name, vessel permit number, fish length, fish weight, type of trip (charter/private), fishing technique, bait type, fight time, number and species of fish released.

This data set contains the logbook data from U.S.A. Commercial Passenger Fishing Vessels (CPFV) fishing in the U.S.A. EEZ and in waters off of Baja California, from 1980 to present. These fishing vessels carry sport fishermen and target both HMS and non-HMS species. California CPFV operators submit mandatory logbooks to the California Department of Fish and Wildlife (CDFW). CPFV operators in Washington and Oregon that target albacore submit mandatory logbooks to SWFSC since the implementation of the HMS Fisheries Management Plan in 2005. Logbook data contain information on locations fished, ports of landing, number of anglers, hours fished, species, number of fish kept, and interactions with marine mammals.

This project monitors the reported recreational Pacific bluefin tuna catch in California by industry on sportfishingreport.com. The data is a tally of bluefin kept per day. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000454.

The data set contains information on retail market spot check audit purchases of tuna in airtight containers. Data are available from May 2001 to present with new data appended annually. Information includes the date, location, product type, store information where random spot check purchases were made throughout the United States and Puerto Rico. Information on purchased product allows the manufacturer, distributor or importer to track the tuna back to harvest and verify the dolphin-safe status of the tuna product.

This data set contains pounds and value for all seafood products that are landed and sold by established seafood dealers and brokers in the SE Region of the US mainland. In the US Caribbean, the landings are reported by permitted fishers. These types of data, referred to as the general canvass landings statistics, have been collected by the NOAA Fisheries Service, National Marine Fisheries Service and its predecessor agency, the Bureau of Commercial Fisheries. These data are available on computer since the mid 1920s. The quantities and values that are reported in this data set include monthly landings that were initiated in 1972. Between 1926 and 1971, data were collected annually and not monthly. Mixed annual and monthly data occur from 1972-1976 according to State and year. The general canvass landings include quantities and value for all commercially caught marine species and are identified by species or species group. These data are collected from or reported by every seafood dealer or broker that is licensed by each state in the Southeast Region (North Carolina through Texas). In addition, information on the gear and area of capture is available for most of the landings statistics in the data set except for Florida 1977-1996 and Louisiana 1992-1999. However, because these data are summaries, they do not contain information on the quantities of fishing effort or identifications of the fishermen or vessels that caught the fish or shellfish. In early years, these data were collected by field agents employed by the Southeast Fisheries Science Center and assigned to local fishing ports. These individuals would canvass the seafood dealers and record the quantity and value for each species or species category from the sales receipts maintained by the seafood dealers. Based on their detailed knowledge of the fishing activity in the area, the agents would estimate the type of fishing gear and area where the fishing was likely to have occurred. It should be noted that landings by gear and water body (fishing area) does not reside in the monthly landings data set for Florida for the years, 1977-1995, Louisiana 1990-1999, and Texas (for gear) from 1993 to present (this is subject to change for years 2008 and more recent). Annual landings by gear, water body and distance from shore are available in the Annual General Canvass data for Florida. More detailed information on the caveats associated with these data is provided in the Issues section. In more recent years, the states in the Southeast Region began to implement trip ticket programs that required the licensed seafood dealer/brokers to report the landings of all seafood products. A trip ticket program was initiated in Florida in 1985, in North Carolina in 1994, in Louisiana in 1999, in Alabama in 2000, and in Texas in 2007. In addition to the quantities of these landings, the states require dealers to report the price, the type of gear and the fishing area for each trip. Through cooperative agreements with each of the states, monthly summaries of the states trip ticket programs are provided to the Southeast Fisheries Science Center (SEFSC) and are included in the general canvass landings data set. In addition, summarized data are extracted from the NOAA-SEFSC Gulf Shrimp System for commercial landings of shrimp species that are landed at port in the coastal area of the Gulf of Mexico.

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Case Study "Southern bluefin tuna". The full Case Study, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Case Study are accessible through the "On-line Resources" section of this record. DESCRIPTION OF THE FOCUS OF THE CASE STUDY Southern bluefin tuna (SBT) are an important apex predator within Australia’s marine environment with juveniles seasonally aggregating in the Great Australian Bight during the summer, subadults and adults utilising southern and south-eastern waters primarily during the winter months and adults aggregating in an areas off the north western region of Australia primarily during the spring and summer months on the only spawning ground for the species. Southern bluefin tuna are a highly prized target species of international commercial and national recreational fisheries. Within Australian waters, a purse-seine fishery catches juvenile (2-4 yr old) SBT in the waters of the Great Australian Bight during the summer months, and is of significant value to the regional economy (~$150M annually). A longline fishery targeting large SBT off the eastern Australian seaboard during the winter months catches a smaller amount of Australia’s commercial allocation. ISSUES OF IMPORTANCE The SBT spawning biomass (a measure of the adult population) is estimated to have been depleted by fishing to a low fraction of its original size. The depleted nature of the stock has led to the listing of SBT as Conservation Dependent under the EPBC Act and Critically Endangered by the IUCN. Unaccounted mortalities associated with discards, unreported catches and recreational catches of SBT can impact on achieving current stock rebuilding targets set by the CCSBT. DATA STREAM(S) USED IN CASE STUDY The case study is based on stock assessment information produced in annual reports of the Extended Scientific Committee and the Commission for the Conservation of Southern Bluefin Tuna. Assessments are based on data relating to fishery catches, aerial surveys and close-kin mark recapture methods covering the spatial area of the Commission and a temporal period of 1951-2014.

This data set contains summarized pounds of select pelagic fish species bought by selected federally permitted seafood dealers in the SE Region of the US mainland. Data was collected 2 times each month and used for quota monitoring.

This is a federally mandated log which is required to be mailed in to NMFS after a fishing trip. This data set includes transshipment and sales information for a lobster fishing trip. There is only data from one year, either 1994 or 1997 (verification is ongoing).
