- Measurements
- Identify from which end the captain is starting. If the release cage end, start with 9 “far” pots. If the block end, 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.
