REPORT OF THE STANDING COMMITTEE ON RESEARCH ... - Iccat

SUB-COM STATISTICSFor by-catch in general, there is no basic catch information being routinely collected in ICCAT so as toevaluate the total removals. There’s partial information collected in different observer programs that are notcentralized in ICCAT. The Group is trying to create an observer metadatabase so as to evaluate the quantityand quality of the information available.8. For each stock, please chose and describe the recommendations of the scientific group for theassessment analysesa. Incomplete data, the group doesn’t recommend any further analysis with it.For by-catch in general.b. Highly deficient data of catch and effort need to restrict analyses to simple aggregated models.For seabirds in particular.c. Sufficient data to carry out age/or group aggregated analysisd. Sufficient data to perform size base evaluations9. What were the priorities identified by the scientific working group in order to improve data input forfuture assessment analysis (one per stock, in priority order)Institute data collection procedures which permit quantifying the total catch (including by-catch) compositionand disposition by the tuna-fleets and report those data to ICCAT. As in the past, the Sub-Committeerecommends that scientific observer and logbook programs, in combination, be used to collect dta useful forquantifying total catch (including by-catch) compositon and disposition by the tuna fleets and report these data toICCAT.10. Other recommendations to the data collection programs (i.e. individual ICCAT members) or theSecretariat data management group.That national scientists provide 5x5 bird by-catch rates for the years, months, and grids for which thatinformation is available.219
