Fishing smarter: How harvesting marine fisheries is changing in the 21st century
Dr. Paul Winger
Fisheries and Marine Institute
Memorial University
Since our founding as the College of Fisheries in 1964 through to the development of our Ridge Road campus as the Institute of Fisheries and Marine Technologies to our affiliation with Memorial University in 1992, we have been dedicated to fostering economic development in the strategic marine sectors of our economy and enabling our people to participate in the marine industry nationally and internationally.

5. Drivers for Innovation?
Economy
Fuel prices
Fish prices
Regulatory
Resource Allocation (TAC)
Gear Technical Measures
Closed areas
Market forces
Consumer preferences
Low cost imports
Eco-labeling and certification

6. Soaring fuel prices in 2008 reduced the profitability of traditional fishing enterprises in Canada.
Increased expenses have threatened the economic stability of the entire sector.
Unstable fuel prices have provoked a need to implement energy saving technology and practices.

7. Common Ecological Impacts:
Bycatch / Selectivity
High fuel consumption
Carbon footprint (CO2 Emissions)
Unaccounted fishing mortality
Loss of habitat
Ghost fishing
Seabed impacts
Entanglements

10. Finite Element FE model (UK-Scot)
Numerical Modelling
Finite Element FE model (UK-Scot)
Flow model (FR)

11. Numerical Simulation Advantages:
DynamiT
SimuTrawl
Advantages:
Evaluate feasibility of preliminary concepts
2) Examine the effect of alterations in design and rigging
3) Examine the effect of speed and rigging changes
4) Measure gear geometry and orientation
Measure forces acting on the gear
Measure downward forces on the seabed
