Enter the trip identification number assigned by the SOP.
Record the date haul was retrieved (dd/mm/yy).
Record the haul number.
Was this haul mixed with another prior to sampling? Circle Yes or
No. This should not happen often.
Record the common or scientific name for the species. Note that if
there are multiple sample types, there may be more than one entry
(row) for some species. For example, shrimp species A may be part
of the retained species sample (sample type 3A) and part of the
discard sample (sample type 3C).
Record the 3-letter code for the species or species group (Appendix
7).
Record the appropriate code for Sample Type. Codes are defined
as follows:
1 Whole haul The entire haul was monitored for
this species and you are 100%
confident that all individuals were
seen.
2 Unsorted random
sample
Used for trawl samples collected
before crew does any sorting
3A-C Sorted sample Used for trawl samples collected
after crew sorts retained from
discards.
3A Retained (sorted All retained fish that have been
by species)
3B Retained (mixed
species)
3C Discard sample
4 Longline,
demersal
5 Gillnet
sorted to species should be weighed.
Collect a random subsample of
retained species that are mixed
together (typically smaller sizes of
several similar looking fish). Sort &
weigh by species. Estimate total
weight of the mixed species and
record on page 2.
Collect a random subsample of
discards. Sort & weigh by species or
species groups. Estimate total
weight of the discards and record on
page 2.
