Play 1: 了解⼈們需要什麼這項服務將解決哪些⽤⼾需求？

為什麼⽤⼾想要/需要這項服務？

關鍵⽤⼾是哪些⼈？

那種⼈會在使⽤服務時遇到最多困難？

⽤什麼研究⽅法？

這些發現會如何建檔？未來團隊成員將如何取得這些檔案？

要多頻繁的與真實的⼈進⾏測試？

Researcher/Management

• Sustainable fisheries

• Estimate allowable catch for each species

• Limit the effort: number of ship/trip/fishing time

• Reduce by-catch/discard

• Combat illegal, unregulated and unreported fisheries

Issues

• Fisheries independent data are expansive

• Measurement and sampling are time-consuming

• Effort data?

• By-catch and discard data?

Dynamic nature of ocean and ecosystem-based fisheries management

Ecological

Economical

Social

Dynamic ocean management*

Data: NE multispecies fisheries

Static vs. Dynamic Management Measure

Static Dynamic

Time-area disclosure

• Grid-based closures • Real-time closures

based on move-on rules

• Oceanographic closures

Evaluation criteria• Reduced identified bycatch or discards

• No or minimal negative effect on the catch of target species

• No or minimal negative effect on the catch of other non-target species

• No or minimal spatial or temporal displacement of by catch

• Economically viable for the fisher (O’Keefe et al., 2013)

Discussion

• Although result clearly shows the efficiency of dynamic measure, DOM requires high-resolution in both spatial and temporal data and rapid-transfer of management decisions
