    • Note serial number of recovery cage and mark as “deployed” in the Edgetech app as deploying pot
  • GPS
    • Set waypoint prefix to “2306-2”
      • From the main menu, select Setup, then Waypoints, then change prefix
    • Start recording track upon arrival
      • From map screen, press ENTER twice
    • Mark waypoints when first and second blocks are deployed
      • Press MARK then ENTER
    • Mark waypoints when pots are deployed (not often possible)
    • Stop recording track
      • From map screen, press ENTER, select STOP, then SAVE

Recovery

  • Ropeless gear
    • Turn on tablet >10 minutes before recovery and open Edgetech app to acquire GPS signal
    • Affix transponder to deck box and turn box on. Confirm that box is connected to tablet
    • Stop vessel, place transponder in water
    • Trigger release
    • Recover transponder, turn deck box off
  • GPS (buttons as above)
    • Start recording track when moving to retrieve
    • Mark waypoints when ropeless cage, first and second blocks are recovered
    • Stop recording track
  • Misc. Prep
    • Place UMCES-provided fish totes on Integrity-provided fish totes to create a shelf near the starboard gunwale
    • Half-fill the totes with water
    • Half-fill the kill bucket with water and add one pouch of MS-222
    • Wet the weigh bucket and take a tare weight
  • Measurements
    • Identify from which end the captain is starting. If the last pot deployed, start with 9 “far” pots. If the first pot deployed, start with 6 “near” pots.
    • All fish from first stratum are placed into one bin, those from the stratum are placed into the other. Recorder keeps track of when to switch bins (6 pots for near-first recovery, 9 pots for far-first).
    • Person on gunwale reads off pot tag ID and enumerates organisms. Recorder notes on data sheet.
    • A total of 30 BSB are retained for measuring, preferably 15 per near/far stratum.
    • If confident that 15/stratum will be caught, others can be immediately released.
    • While transiting to next site, record weight, length, and sex of 30 individuals per fish species.
    • If more than 15 fish/stratum available, measurements should be evenly split between strata.
    • 5 fish per stratum are retained for diet analyses; signs of barotrauma, esp. everted stomachs should be carefully noted.
