When a recapture report is submitted several checks are done on the data. There are two classes of checks, warnings and errors. Errors are generated for impossible or highly unlikely
data values. Warnings indicate that the data are suspicious. The various error checks are described below for each field.
= Warning
= Error
Tag number
Tag number does
not exist in the database
Date
Not a valid date (e.g 30 February) A date in the
future Already a
recapture for the tag on the same date (this prevents duplicates)
Before the last recapture for the tag More than 6 months
before the last recapture for the lobster More than 3 years
since the last recapture for the lobster More than 10 years
since the last recapture for the lobster Not a number More than 2mm less
than the tail width at the last recapture for the lobster More than 10mm
less than the tail width at the last recapture for the lobster More than 20mm
greater than the tail width at the last recapture for the lobster More than 40mm
greater than the tail width at the last recapture for the lobster Tail width and
date imply that the lobster grew more than 5mm/year Tail width and
date imply that the lobster grew more than 10mm/year Tail width and
date imply that the lobster shrunk more than 2mm/year Tail width and
date imply that the lobster shrunk more than 5mm/year Different from the
sex recorded when the lobster was first releasedLatitude and longitude
Not a valid
latitude or longitude (e.g. a latitude of 45 67.423 is not valid
because the minutes are greater than 60) Position is on land Position may be in
water deeper than 200m Statistical area
is not consistent with the position entered Position and date
imply that the lobster moved more than 1nm per day Position and date
imply that the lobster moved more than 10nm per day Position and date
imply that the lobster moved more than 10nm Position and date
imply that the lobster moved more than 100nm Not a valid
statistical area Statistical area
is not consistent with the position entered
