Using a deterministic, annualized steady-state model, this study provides a quantitative evaluation of the total number, total catch, and ex-vessel gross revenue (hereafter termed revenue) of abalone harvested under 10 monthly fishing scenarios in which the proportion of either the current TACC or current number of greenlip harvested was varied among months.
In 2011, the greenlip TACC was 69 t bled meat weight (~207 t whole weight) at a minimum legal size of 145 mm in shell length.
For HS[DELTA]CN, we used the current region A TACC (69 t meat weight) to determine the number and value of greenlip harvested for all scenarios.
The proportion of TACC harvested each month ([P.sub.TACC](m)) was prespecified for each intraseasonal fishing scenario tested (Fig.
However, for HS[DELTA]CW, the TACC was varied such that the number of greenlip harvested under each scenario was [C.sub.N] = 277,481, which matched the mean annual number harvested from scenario 1 with the current TACC of 69 t derived from HS[DELTA]CN.
For most of these fisheries, species-specific CPUE is either not estimated (Bene & Tewfik 2001, Basurto 2006, Kinch 2002, Uthicke & Conand 2005) or is estimated only for that species comprising the highest proportion of the total allowable commercial catch (TACC) (Hart et al.
However, these measures need to be calculated because each species has a separate TACC, which is reviewed annually following species-specific stock assessments (e.g., Chick et al.
