About the data

This species first recruits to the survey gear in June. All sampling stations are used to calculate the index of abundance.

The young-of-year cutoff values are as follows (index months are listed in bold):
  • June: 0-90 mm.
  • July: 0-120 mm.
  • August: 0-150 mm.
  • September: 0-180 mm.
  • October: 0-200 mm.
  • November: 0-200 mm.
  • December: 0-200 mm.
  • January: 0-200 mm.
  • February: 0-200 mm.
  • March: 0-200 mm.
  • April: 0-225 mm.
  • May: 0-240 mm.

Data collected after the transition to a new vessel and net in June 2015 have been adjusted by a species-specific calibration factor.
