Table of effort, captures, by fishing year. For each fishing year, the table gives the total number of tows; the number of observed tows; observer coverage (the percentage of tows that were observed); the number of observed captures (both dead and alive); and the capture rate (captures per hundred tows). Due to Ministry for Primary Industries anonymity requirements, fishing effort is only shown if there were three or more vessels and three or more companies or persons fishing in that year. For more information on the methods used to prepare the data, see Abraham and Thompson (2011b).
