Steve Brouwer Oceanic Fisheries Programme Pacific Community How The data you provide contribute to analyses for your country Steve Brouwer Oceanic Fisheries Programme Pacific Community

National Scientists

Regular analyses FAD closure reports Longline reports Country webpage updates NPOA and shark/seabird/sea turtle management plans

Longline reports Using logsheet catch & effort data as well as oceanography data

Using logsheet catch & effort data as well as observer and economic data Due to lower CPUE in the FAD closure months days are less valuable at that time of year FAD closure reports If no FAD closure: on average vessels fishing in PI waters were estimated to make 5% more Overall effort has increased in Pacific Island waters since 2009 and has remained relatively stable over the last 5 years

But the distribution of effort between PNA members has also changed, benefitting some countries but not others Proportion of effort

NPOAs and exploratory fisheries Use logsheet catch & effort data but very reliant on good observer data

Periodic requests Longline value Using logsheet catch & effort data as well as observer, vessel and economic data

Set catch limit for Albacore We can use these data to estimate how many vessels should fish in your waters Set catch limit for Albacore Estimate the expected hooks required Albacore CPUE CPUE and hooks set both vary across the fleet BET & YFT CPUE Estimate the bigeye and yellowfin bycatch Estimate the expected number of vessels Average hooks per set BUT the number of hooks matter so you need to limit those if you want to maintain catch rates and have no controls on catch

Big catch today increases the chances of a small catch tomorrow

Bioeconomic analyses Maximum profit Cost Profit $$$ Revenue Loss Most profitable level of effort Cost Profit Revenue $$$ Break even point Loss Effort

Bioeconomic analyses Maximum profit $$$ Low cost Loss Effort

Bioeconomic analyses High cost Maximum profit $$$ Loss Effort

Bioeconomic analyses Medium cost $$$ Low revenue Effort

Low cost ($1.1/hook) per hook Or maximise the number of vessels to increase licence revenue Choose do you want to maximise profit for vessels. Medium cost ($1.5/hook) per hook High cost ($2/hook) per hook

Summary Providing logsheet and observer catch, effort and, vessel information allows us to do analyses that help you: Assess your fisheries Make informed management decisions and plans Plan fishing strategies and negotiations with countries/companies wanting access to your waters Develop underexploited stocks in your EEZ Shows where information gaps exist If there are any analyses that you would like us to do, just email grahamp@spc.int we can do the work for you or help you do it yourself through attachments
