Conclusion

These results are an excellent start and demonstrate potential opportunities to link boat profitability with reduced environmental impact. 

As a result of this work, fishermen are already realizing substantial benefit: 

“With a 7 inch square-mesh codend I lost fish but got a better fish price and offset my loss” 

“The fuel flow meter is making me think harder about fuel consumption” 

“I used the new trawl and reduced my fuel cost by around 17%” 

Future work includes: 

  • Testing the large-mesh trawl in other regions of the fishery and measuring catching performance
  • Testing semi-pelagic otterboards to reduce fuel consumption and seabed impact 
  • An energy audit of several boats to explore further opportunities for energy savings
