1 0 SCTB15 Working Paper SKJ 3 A summary of aggregate catch/effort and size composition data available to the SCTB SKIPJACK Oceanic Fisheries Programme Secretariat of the Pacific Community Noumea, New Caledonia July 2002

2 1 INTRODUCTION The following provides a summary of aggregate catch/effort and size composition data available to the Standing Committee on Tuna and Billfish (SCTB). The summarised information provided in the tables herein have been ordered by species, gear and vessel nation to better cater for the requirements of each SCTB Species Research Group (SRG). It should be noted that public domain data are aggregated across all vessel nations. The tables have rows corresponding to the existence of annual catch estimates for that species, gear and vessel nation. For each line, the temporal ("TIME") and spatial ("AREA") stratification of the available data are included; an explanation of the codes used is provided in the appendix. Each line also includes the number of available records for catch/effort and fish size samples for that time/area stratum. Similar information is also presented in the form of time-line graphs for each species and gear. More detailed quantitative measures of the OFP data holdings, including the sources of data provided, are available in the OFP Data Catalogue, which can be found on the SPC website ( Detailed text on the sources, coverage and quality of data exist for catch and effort data, but have not been included in this document at this stage. It is hoped that similar text can also be prepared for size composition data in future versions of this report.

For catch and effort, the data originally provided were annual estimates, although estimated data exist for finer temporal strata based on ancillary information. The data provided were stratified by QUARTER. The data provided were stratified by MONTH. Table A2. Codes for Area stratification. Code Description 5 Five degree squares 0 Ten degree squares T Ten by twenty degree rectangles C Data aggregated by broad area (larger than 10 x20 rectangles) A Data available at the level of broad area, typically exclusive economic zones (EEZs) F Data aggregated to the extent of this fishery (dependent on gear and flag). For catch and effort, the data originally provided were annual estimates, although estimated data exist for finer spatial strata based on ancillary information. Table A3.
