Preventing Whale Entanglements while improving the POT fishers business

Marco and Jacob present at the first Ropeless Fishing orientated conference. Covering Desert Star's ARC-1, Marco and Jacob report on the state of the worlds fist and only ropeless fishing system in use since 2013 in New South Wales, Australia.

Preventing Whale Entanglements while
Improving the Pot Fisher’s Business:
ARC-1XD
A Rope-less Fishing Method
Marco Flagg & Jacob Wolf
WHOI Ropeless Fishing Workshop
01-Feb-2018
z
ARC-1XD
 Environmental Benefits
 Effective Prevention of Marine Mammal Entanglements
 Ghost Fishing Mitigation (increase in CPUE)
 Benefits to Fishers
 Releases for peak market price (lobster and crab)
 Easier fishing in high currents (.75 now 2 knots)
 Gear theft and ship strike protection
 Better time management (fishing, boat maintenance, day off)
z
ARC-1XD Field Demo (Video)

z
Fishermen's Experience
 New South Whales Rock Lobster Fishery
 Continuous use since 2013
 300+ traps, ~1000 years in water
 Some fishers invest heavily & transform
their business
 Others try & struggle
 Many more are watching and waiting
z
Fishermen's Experience
 The ARC-1XD Release is ~99% Effective (Scott
Westley)
 About 97%-98% recovered by remote release, rest
talking and grappled with 2% gear snags and 1%
release failures.
 About 1% not talking. Mostly trap moved by bottom
trawlers. But release failures such as flooding, battery
connector fail, component fail also observed.
z
Fishermen's Experience
 Getting operations right is the challenge
 Well serviced acoustics, ropes, floats, bags,
boat equipment
 Well thought out trap deployment & recovery
procedure
 Understanding environment & boat impact on
performance

Preventing Whale Entanglements while improving the POT fishers business

  • 1. z Preventing Whale Entanglements while Improving the Pot Fisher’s Business: ARC-1XD A Rope-less Fishing Method Marco Flagg & Jacob Wolf WHOI Ropeless Fishing Workshop 01-Feb-2018
  • 2. z ARC-1XD  Environmental Benefits  Effective Prevention of Marine Mammal Entanglements  Ghost Fishing Mitigation (increase in CPUE)  Benefits to Fishers  Releases for peak market price (lobster and crab)  Easier fishing in high currents (.75 now 2 knots)  Gear theft and ship strike protection  Better time management (fishing, boat maintenance, day off)
  • 3. z ARC-1XD Field Demo (Video) https://youtu.be/WeeieRr7sTw
  • 4. z Fishermen's Experience  New South Whales Rock Lobster Fishery  Continuous use since 2013  300+ traps, ~1000 years in water  Some fishers invest heavily & transform their business  Others try & struggle  Many more are watching and waiting
  • 5. z Fishermen's Experience  The ARC-1XD Release is ~99% Effective (Scott Westley)  About 97%-98% recovered by remote release, rest talking and grappled with 2% gear snags and 1% release failures.  About 1% not talking.

  • 6. z Fishermen's Experience  Getting operations right is the challenge  Well serviced acoustics, ropes, floats, bags, boat equipment  Well thought out trap deployment & recovery procedure  Understanding environment & boat impact on performance
  • 7. z Fishermen's Experience Problems & Solutions Problem: After years of good performance, suddenly couldn't talk to most releases. Solution: Dive check found boat transducer barnacle coated despite recent haul-out. Transducer is now regularly inspected.
  • 8. z Fishermen's Experience Problems & Solutions Problem: Fishing in more shallow water than normal, sometimes it was hard to link to releases. Solution: There were also strong winds and currents. In shallow water, transducer coverage cone is smaller, and boat drifted past trap too fast. Steaming against the current/seas solved it.
  • 9. z Fishermen's Experience Problems & Solutions Problem: After months of continuing use, almost half of releases reported trigger but floats didn't surface. Solution: Barnacles had grown all over releases and bags. Gear is now cleaned between deployments to stop the growth cycle.
  • 10. z Fishermen's Experience Problems & Solutions Conclusion:  Experienced support of new fishers is essential to teach  Be aware of regional differences in conditions and their impact on the system
  • 11. z Common Concerns Concern Gear overlay without surface buoy Solution Not with the Rope-less Fisher App
  • 13. z Common Concerns Concern Added handling time Solution No added handling time per trap with boat optimized fishing strategy New broadcast release mode; buoy automatically surfaces as boat approaches
  • 14. z Example of 3 man system: F/V-Seeking (NSW)  Avoid increased handling time per trap  3 man system  Captain – Release, Range, and Trigger  Crew 1 – Bag stuffing and arming, catch tagging and boxing  Crew 2 – Trap and bait
  • 16. Crew 1: Bag stuffing & arming, catch tagging and boxing
  • 17. Crew 2 Trap and bait
  • 18. z Common Concerns Concern Solution Cost offset by business operational advantages Lower cost version in testing (ARC-2) Cost and maintenance
  • 19. z Fishery Integration  Pilot program recommended  3 day class for fishers by Marco Flagg  Individual boat integration support  Individual training and fine-tuning at sea • Fishery Association should spearhead pilot program. Community purchasing for lowest cost
  • 20. Pilot Fisher Class and individual support by Desert Star Pilot Program Fishermen Fishermen Fishermen Pilot Fisher Fishermen
