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?

• 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
