JustificationRationale
Size, age and sex parameters appear to be documented for the offshore and some costal fisheries MRFDB, across a range of gears Table 4. It also appears from the publications that the level of analysis by each MFRDB
institute is quite extensive, if not regular. A major weakness appears to be the inadequacy of coastal fleet data and the impact that this element of the
fleet has on stock status. Only a limited amount of size, sex and age data is collected at the coastal level. DoF District and Provinces have undertaken some coastal surveys on fleet composition and are presently
supporting the registration of all fishing vessels. A 5 year community based survey is believed to be proposed Funge Smith, Oct, 2011. Based on available evidence, information is not sufficient and must incorporate
coastal parameters. Log book data collection would appear to be unreliable Apirak, Sept, 2011, though some information is
available on other fleet removals e.g., from shrimp trammel nets, push nets and trawl.

Scoring issues SG60
SG80 SG100
a. Appropriatenes
s of assessment to stock under
consideration The assessment is appropriate
for the stock and for the harvest control rule.
The assessment takes into account the major features
relevant to the biology of the species and the nature of the
fishery.
b. Assessment approach
The assessment estimates stock status relative to
reference points.
c. Uncertainty in the
assessment The assessment identifies
major sources of uncertainty.
The assessment takes uncertainty into account.
The assessment takes into account uncertainty and is
evaluating stock status relative to reference points in
a probabilistic way.
d. Evaluation of assessment
The assessment has been tested and shown to be
robust. Alternative hypotheses and assessment
approaches have been rigorously explored.
e. Peer review of assessment
The assessment of stock status is subject to peer
review. The assessment has been
internally and externally peer reviewed.

JustificationRationale
There is some evidence that MFRDC have implemented stock assessment processes in the sub offices and that there is now a degree of coordination Jindalikit pers com, 2011. This may not apply to all areas, but early
indications are encouraging to the extent that MFRDB is now building up a composit information on stock status. There is one known case study Apirak et al, 2011, where stock assessment is taking place at the coastal
level. Growth age, sex, weight and length form the components to the assessments. These assessments are based on
Jo es length-based cohort analysis length and frequency mortality coefficients to calculate biomass and MSY.

Status The fishery does not pose a risk of serious or irreversible harm to the retained species and does
not hinder recovery of depleted retained species.

a. Retained species stock
status Main retained species are
likely to be within biologically based limits.
If not, go to scoring issue c below.
Main retained species are highly likely to be within
biologically based limits. If not, go to scoring issue c
below. There is a high degree of
certainty that retained species are within biologically
based limits and fluctuating around their target reference
points.
b. Target reference
points Target reference points are
defined for retained species.
