AKRO/SF: Catch Accounting System (CAS)
The Catch Accounting System (CAS) creates total catch estimates for the groundfish fisheries in the Bering Sea/Aleutian Islands and Gulf of Alaska. Each year, quotas are established in the CAS that match the annual harvest specification tables for federally managed groundfish fisheries off Alaska. The output of the CAS is the total amount of groundfish that is retained and the amount that is discarded at sea. In addition, the system creates estimates of the total amount of non-groundfish species -- both prohibited species and non-target species -- that are caught in the groundfish fisheries. Prohibited species catch (PSC) consists of salmon, halibut, and several species of crab. All the PSC species have economic value in non-groundfish fisheries and therefore cannot be retained in the groundfish fisheries. Non-target catch are species like coral, sponges, etc., and catch of these species needs to be calculated in order to evaluate the impact of the groundfish fisheries on the ecosystem. The CAS uses a combination of industry reports and onboard observer information to provide an estimate of total catch and bycatch. Industry reported data consists of catch (landing reports) and processed product amounts (production reports), and these reports are electronically recorded and submitted to NMFS via eLandings. The observer data are collected by the Alaska Fisheries Science Center (AFSC) using a stratified sampling design. Other sources of information come from the Alaska Commercial Fisheries Entry Commission (CFEC), which issues permits and vessel licenses, and Vessel Monitoring Systems (VMS), which collect the position, time at a position, and course and speed of fishing vessels.

AKRO/SF: Blend System
공공데이터포털
The Blend was the system used by the NMFS Alaska Regional Office to monitor groundfish catch from 1991 until 2002. The Blend system combined data from industry production reports and observer reports to make the best, comprehensive accounting of groundfish catch. These data were used to manage quotas for groundfish in the Gulf of Alaska, Bering Sea, and Aleutian Islands. The blend catch data were also used as the basis for computing estimates of prohibited species bycatch. Prohibited species include Pacific halibut, salmon, herring, and crabs. Blend data were used for numerous regional and national reports, fishery stock assessments, and analysis of fishery management plans. The Blend system used a combination of industry reports and observer data. For shoreside processors, Weekly Production Reports (WPR) submitted by industry were considered the best source of data for retained groundfish landings. All fish delivered to shoreside processors were weighed on scales, and these weights were used to account for retained catch. Observer data from catcher vessels provided the best data on at-sea discards of groundfish by vessels delivering to shoreside processors. Discard rates from these observer data were applied to the shoreside groundfish landings to estimate total at-sea discards from both observed and unobserved catcher vessels. For observed catcher/processors and motherships, the WPR and the Observer Reports recorded estimates of total catch (retained catch plus discards). If both reports were available, the Blend System selected one of them for incorporation into the catch database. If the vessel was unobserved, only the WPR was available. In 2003, the Catch Accounting Sytem was implemented and took advantage of industry reports at a more detailed level, especially from shoreside processors. The Blend system was based on weekly data from processors and was not capable of accounting for some management programs -- including cooperatives, sideboards, complex seasonal allocations, Harvest Limit Area quotas, and quotas assigned to vessels of a particular size class. The Catch Accounting System replaced the Blend as the tool used by the National Marine Fisheries Service to estimate total catch in the groundfish fisheries off Alaska.
Catch-In-Areas Main
공공데이터포털
The Catch-In-Areas database integrates catch data from the Catch Accounting System (which has the spatial resolution of a NMFS Reporting Area) into a database that resolves the GIS data into polygons of approximately 7.5 km. In unrestricted outside waters, sixty four grid IDs fit inside one state statistical area. A state statistical area is = degree in latitude and one degree in longitude block. The 7.5 km grid size was picked for two reasons 1) we were likely to pick up at least one 30 minute VMS ping for a vessel running at fishing speed; and 2) the size (.125 degree latitude) is perfectly divisible in geographic coordinates so they fit perfectly inside a state statistical area. The grid polygons are often further divided into smaller polygons by the boundary of state statistical areas, the boundary of state and federal waters, or by the boundary of Steller sea lion critical habitat (broken out at 3, 6, 10, and 20 nautical miles from each of the 154 Steller sea lion rookeries and haulouts). Where confidentiality and mapping is an issue, seven-kilometer polygon are pre-coded for grouping into (3x3) 23km polygons. Each grid-id can queried individually or by sets of pre-coded attributes, such as reporting area and distance from Steller sea lion sites.
AFSC/FMA/NPRB Alternative Catch Monitoring Table and Column Definitions
공공데이터포털
These data arise from a field study of groundfish catch monitoring in Kodiak, AK trawl fisheries. Two monitoring components were included in the study: 1) at-sea sampling methods used by observers to sample species composition of catch and 2) shore-side sampling of delivered catch by observers to validate landings species composition reports. The at-sea portion of the study consisted of a side-by-side comparison (two observers) of a proposed new sampling method and the standard sampling method. Observer data were recorded at-sea on paper and transferred to an Oracle database. The shoreside component of this study consisted of observer species composition sampling in plants for later comparison with landings data. The shore-side data were collected by observers in processing plants, recorded on paper and transferred to an Oracle database. Data collection started in April 2011 and continued through August 2011. Third party landings data (NOAA Fisheries, Alaska Regional Office, Sustainable Fisheries Division) that were used in the analysis are stored in an oracle database. Data for both project components (at-sea and shoreside) were collected during normal fishing activities onboard commercial trawl catcher vessels and during normal processing activities in shore-based processing plants.
AKRO/SF: Electronic Logbooks
공공데이터포털
Logbooks are the industry reports submitted by vessels documenting fishing activity. In particular, these reports provide haul specific information, gear, fishing depth specifics, and vessel estimates of catch. Logbooks may be completed either on paper or in an electronic format. Paper logbooks are required to be completed and submitted for federally permitted vessels over 60 feet in length that are fishing for groundfish and for vessels that are 25 feet and over in length fishing for IFQ halibut. The submission of electronic logbooks is required for trawl catcher/processors participating in the American Fisheries Act (AFA) and Community Development Quota (CDQ) pollock fisheries in the BSAI, trawl catcher/processors participating in the Central GOA rockfish program, and longline catcher/processors fishing for Pacific cod if required to weigh the Pacific cod on a NMFS-approved scale. Some other catcher processors and catcher vessels voluntarily submit an electronic logbook instead of a paper one.
AFSC/FMA/Observer Declare and Deploy System (ODDS)
공공데이터포털
Groundfish vessels fishing in federal waters off Alaska are either in the "full coverage", "partial coverage", or "zero coverage" categories according to the monitoring specifications outlined each year in the Annual Deployment Plan. Vessels in the Partial Coverage (PC) category are subject to random selection for observer coverage or electronic monitoring on a trip-by-trip basis. PC vessels are typically catcher vessels using longline, pot, or trawl gear and are required to log each trip into the Observer Declare and Deploy System (ODDS) prior to departure to determine if the trip is "selected" for observer coverage or electronic monitoring. If a trip is selected vessels must comply with all monitoring requirements on that trip. Broadly speaking, the Observer Declare and Deploy System is the data system that houses all trip logging data and the associated monitoring rates, and provides a user interface for vessel owners to log trips and for the contracted observer provider(s) to assign observers to selected trips.
AFSC/FMA/Electronic Monitoring (EM) Data Transformation
공공데이터포털
One type of electronic monitoring of Alaska groundfish catch has been conducted by Pacific States Marine Fisheries Commission using an electronic monitoring (EM) system to collect catch accounting data using video and sensor data of selected fishing vessels in Alaska. Video recordings of fish catch composition aboard selected vessels are collected are stored on hard drives in an effort to track vessel catch and discards to accurately debit discarded catch from the individual fishing quota (IFQ) account of each account holder. This information is collected in place of the sampling for species composition of the catch conducted by human at-sea catch monitors or observers. Reviewers of the videos enter data from the drives and maintain data integrity and quality. Raw, reviewed electronic monitoring data collected by Pacific States Marine Fisheries Commission must have additional data items added to it to conform to the standard format of data normally collected by Alaska observers in order for the data to be processed by catch accounting of the NMFS Alaska Regional Office. The EM_OBSINT tables contain these transformed data. These data, like data collected by Alaska groundfish observers, and transmitted electronically to the AFSC and are the source data for those interfaces used for fishery management, scientific inquiry and fishing activity monitoring by industry.

AFSC/ABL: National Marine Fisheries Service - Alaska Sablefish Tag Database
공공데이터포털
This data set captures the tag release and recovery information for sablefish from the early 1970s until present. It also contains tag release and recovery data for several other species (shortspine thornyheads, Greeland turbot, Pacific sleeper sharks, spiny dogfish, and lingcod) which have been tagged by NMFS in AK since the late 1990s.
AKRO: Guided Angler Fish Landings
공공데이터포털
Beginning in 2014, the the halibut Catch Sharing Plan (CSP) authorizes annual transfers of commercial halibut IFQ as guided angler fish (GAF) to charter halibut permit holders for harvest in the charter halibut fishery. GAF offers charter halibut permit holders in Area 2C or Area 3A an opportunity to lease a limited amount of IFQ from commercial quota share (QS) holders to allow charter clients to harvest halibut in addition to, or instead of, the halibut harvested under the daily bag limit for charter anglers. Charter anglers using GAF are subject to the harvest limits in place for unguided sport anglers in that area. Information about GAF landings are submitted electronically through eFish, NMFS' integrated online system, and include details on when and where the GAF were caught, the number and length of fish, as well as permit, vessel, license, and logbook details.
