Principle 1
Component Outcome
PI 1.1.1- Stock status
The stock is at a level which maintains high productivity and has a low probability of recruitment overfishing
Scoring issues SG60
SG80 SG100
a. Stock status It is likely that the stock is
above the point where recruitment would be
impaired. It is highly likely that the
stock is above the point where recruitment would be
impaired. There is a high degree of
certainty that the stock is above the point where
recruitment would be impaired.
b. Stock status in relation to
target reference point
The stock is at or fluctuating around its target reference
point. There is a high degree of
certainty that the stock has been fluctuating around its
target reference point, or has been above its target
reference point, over recent years.
JustificationRationale
Genetic distinctions have been identified for the Gulf of Thailand and Andaman Sea, showing two different stocks Sirawut, K et al, 2007. Some genetic distinctions also exist between specific sites in both the Gulf of
Thailand and Andaman Sea, but could potentially be considered the same stock because of related genetic traits Sirawut, Ibid.
Evidence of overfishing Jindalikit 2008, Apirak 2011 and Sinanun 2011 and reports of declining CPUE and increasing reduction in the average size of crab are common features, but there are some possibilities of
localised recovery following community initiatives Tat, pers com, Oct, 2011.. However, these appear to be very rare, if occurring at all. The offshore fisheries appear to exhibit some robustness, as larger crabs are targeted
Jindalikit, et al, 2008. However, the connect in outward migrations of the juvenile crab to deeper water, and re-migration of females back to shallower water, would suggest that stock is being overfished, and in some
cases Aprirak, 2011, heavily overfished, In the coastal area, and the species is particularly susceptible during its juvenile growth stages. The identified outputs suggest that stock assessment processes need to extend
throughout the range of the fisheries all regions and methods, which would include trap, bottom gillnet and trawl. It is acknowledged that such work is underway, but more details are required on the network of this
research.
