b. Rebuilding timeframes
A rebuilding timeframe is specified for the depleted
stock that is the shorter of 30 years or 3 times its
generation time. For cases where 3 generations is less
than 5 years, the rebuilding timeframe is up
to 5 years. A rebuilding timeframe is
specified for the depleted stock that is the shorter of 20
years or 2 times its generation time. For cases
where 2 generations is less than 5 years, the rebuilding
timeframe is up to 5 years. The shortest practicable
rebuilding timeframe is specified which does not
exceed one generation time for the depleted stock.
c. Rebuilding evaluation
Monitoring is in place to determine whether the
rebuilding strategies are effective in rebuilding the
stock within the specified timeframe.
There is evidence that the rebuilding strategies are
rebuilding stocks, or it is highly likely based on
simulation modelling or previous performance that
they will be able to rebuild the stock within the specified
timeframe.
JustificationRationale
Crab banks form part of the strategy. However, these are intermittent, crab mortality is high 98, and evidence is not sufficiently reasonable to show that they are successful. However, local knowledge suggests
that there may be some partial recovery Phattareeya et al, Sept, 2011. Clearer evidence would be required to illustrate that crab banks and other localised supporting measures closed areas, trawler prohibitions and
increases in mesh size are effective. Similarly, such rebuilding actions would have to be wide-spread. No timeframes have been set and no system of monitoring is place, but there are some initiatives in the
Andaman Sea and a number of case studies in GoT.
