BTS CPUE changes for No length information #15

Open vaishav opened 1 year ago

vaishav commented 1 year ago

CPUE is not calculated -or ends up in -9 because there is no HlNoatLngt available for all specvals other than 1

if a specval allows use in DATRAS products, then: • Where HlNoatLngt is not -9 HlNoatLngth should be used to calculate CPUE (per km2 and/or per hour) • Where HlNoatLngt is -9 (and LngtClass=-9) Nomeas should be used and follow the same steps as Hlnoatlngt (i.e. multiplying with the subfactor, and calculate CPUE)

could we prioritise this topic a bit more? benthos data are used more and more, and the CPUE product is a useful thing in this case. especially now also IBTSWG considers to broaden up the submitted benthos data
