How technological innovation can help us fishing sustainably? In this talk, I start with the conflict among fishers, researcher/ manager and customer then focus on how the technological innovation can help each stakeholder reach the unlikely goal- sustainable fisheries. This is a talk in Fishackathon Taipei, 2016.

7. 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？

20. Bycatch/discard

21. 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

22. Fish stock assessment

24. Issues
• Fisheries independent data are expansive
• Measurement and sampling are time-consuming
• Effort data?
• By-catch and discard data?

33. Dynamic ocean management*

35. Data: NE multispecies fisheries

36. Static vs. Dynamic Management
Measure
Static Dynamic
Time-area
disclosure
• Grid-based closures
• Real-time closures
based on move-on
rules
• Oceanographic
closures

38. 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)

40. 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
