  "neuse_notes":"Natural cut mullet; anchored boat with 4–7 unattended rods in 2–6 m. J comparator was Gamakatsu octopus, not Charleston plain-shank J. Gear bundle changed leader length, weight attachment and weight mass together (short/fixed 0.15m/85g; long/sliding 0.5m/56.7g); years differ. Authors' printed 0.5m/18in are approximate and inconsistent conversions; retain metric rather than improve their source. 2003 lacked concurrent J control. Mortality not measured here. These large-adult bottom rigs are not instructions for a shrimp-under-cork setup."
