data available here for download contains year, month, country code, gear code, CCSBT statistical area, latitude and longitude (by 1 square where available), number of search hours, and weight of SBT retained. Within this dataset, there are occasional missing data (empty cells) for location and number of search hours. It should also be noted that the weight of SBT retained in these data are usually only approximate visual estimates of the weights. SBT size frequency data for commercial fishing operations, raised to the total reported SBT catch of the relevant flag state or fishing entity, are available below. The data contains: year, month, country code, gear code, CCSBT statistical area, other area (Australian catches only), latitude and longitude, length class (upper end of class in cm), length class precision (in cm) and the adjusted (raised) frequency. At present, raised size frequency data at this resolution are only available for Australia (1952 to 2011 - but prior to 2002 this is not separated by gear type and does not include latitude and longitude), Japan (1965 to 2011), New Zealand (1989 to 2011 - but without spatial and temporal stratification in 1989) and the Fishing Entity of Taiwan (2002 to 2011). Where available, the latitude and longitude is presented as 5 squares for longlining and unclassified gear types, and 1 squares for other gear types. The CCSBT Catch Documentation Scheme replaces the CCSBT Trade Information Scheme and has been operational since 1 January 2010. This scheme records all landings of domestic product,
