  2. Introduction Data Collection Duties • Estimate effort for each gear deployment; • Identify every individual caught and assess catch condition and fate; • Collect biological information on target and other identified species as requested; • Record all sightings and interactions with marine mammals and sea turtles; • Record vessel and fishing gear characteristics.

  3. Objectives • List 8 elements on the Set & Haul Information form and describe how each is collected • Define fishing effort • Demonstrate ability to complete the Set & Haul Information forms

  4. Set & Haul Information Form • Complete 1 per set • Fishing effort – time, quantity of gear fished, location

  10. Calculating distance • Distance = Speed * Time • What distance is traveled if you know the interval is 10 seconds and vessel speed is 6 knots? (hint: 1 knot=0.514m/s)

  17. Set & Haul Information Form • Questions on Set & Haul information? • Practice exercise • Groups of 2 • Use handout, manual, partner to complete • Record lengths of branchline components on white board [separate for circle and J-hook]

  18. Activity - answers

  19. Activity - answers Estimated mainline length 38.2m * 1311 = 50,080.2 m If 1nmi = 1852m 50,080.2 / 1852 = 27.041144 or 27.0 nmi

  20. Summary • List 5 elements on the Set and Haul Information form and describe how each is collected • How is fishing effort defined?
