The Fish Assessment data set within the Species Information System (SIS) constraints information related to fishery stock assessments, including assessment meta-data and model results.

The Status Determination dataset within the Species Information System (SIS) contains information related to overfishing, overfished, and approaching overfished status determinations; FSSI score for FSSI stocks; management action required, based on stock status; and information related to rebuilding programs for overfished and rebuilding stocks.

The Annual Catch Limit (ACL) dataset within the Species Information System (SIS) contains information and data related to management reference points and catch data.

Includes outputs from the various models run in the evaluation of stock status for species managed by the International Commission for the Conservation of Atlantic Tuna.

This data set contains catch and effort for fishing trips that are taken by vessels with a Federal permit issued for the swordfish and sharks under the Highly Migratory Species (HMS) fishery management plan. Fishermen that own vessels with permits in these fisheries are required to complete a vessel logbook for every trip in which any species in the Highly Migratory Species fishery management plans are caught and landed. Fishermen are not required to report fishing trips in which other than these species are caught. However, fishermen are required to submit a no-fishing report if they did not fish for or catch any HMS species during a calendar month. In 1986, the Southeast Fisheries Science Center (SEFSC) initiated a logbook program for vessels that held a federal vessel permit to fish for swordfish in the Atlantic Ocean and Gulf of Mexico. In 1993, a similar program was initiated for vessels with a federal permit to fish for sharks that are included in the HMS fishery management plan. In order to provide sufficient level of detail for fishing effort by the longline vessels, the catch and effort data need to be reported for each longline set. Consequently, a single logbook form was designed for the fishermen to record the catch (numbers of animals caught) and effort, which includes data on the length of the longline, the number of hooks and the duration of the set. To reduce the number of times that fishermen need to record certain pieces of information, e.g., location of unloading, duration of trip, number of crew, a trip summary form was designed in 1999 that includes the trip-related information that is the same for every set. This redesign of the logbook form resulted in two forms, the trip summary and the set forms. Only one trip summary needs to be completed for each trip, but a separate set form needs to be completed for each longline set made during the trip. At the same time, additional questions were added to the trip summary form to collect information on the expenses that the vessels incurred during the trip. Initially, this information was voluntary and the fishermen did not have to provide the cost data whereas the catch and effort data are mandatory and the vessels permit will not be renewed if logbooks are not received for every trip where swordfish and/or sharks are caught and landed.

In the interest of efficiency, clarity and standardization of stock assessment materials, the stock assessment reports for the 2015 Groundfish update have been streamlined. Additional information is now available through the SASINF website, a public web based repository of information supplemental to assessment update summary documents. Managers, stakeholders, and other interested parties can view or download figures, tables, model input and output, background information and maps pertaining to each species.

Age and length frequency data for finfish and invertebrate species collected during commercial fishing vessels. Samples are collected by fisheries reporting specialist from fish dealers in ports along the northwest Atlantic Ocean from Maine to North Carolina.

PURPOSE: These data have been updated following a Canadian Science Advice Secretariat (CSAS) Regional Science Advisory Process. Associated publications are available in the citation section below or will be posted on the Fisheries and Oceans Canada (DFO) Science Advisory Schedule as they become available. DESCRIPTION: Commerical landings data maintained by DFO Statistical Services Unit were used to calculate fisheries-dependent catch per unit effort (CPUE) as total landings by number of licences, and total landings by number of days landed for Atlantic silverside in the southern Gulf of St. Lawrence from 1985-2022. USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

This series documents the status of different stocks of fish, invertebrates and marine mammals in Canada as well as some ecosystem and environmental issues. From 1993 to 1996, and 2003 to 2004, Stock Status Reports were numbered by year and sequential number (i.e.: 1993/001). For 1997 to 2002, the SSR numbering system functioned with a permanent alphanumeric identifier number designating first the taxonomic grouping and region, and second the stock number (i.e.: D0-01 (2002)).
