  abstract = {{A}fter seven years of exploitation, {V}anuatu's deep-bottom fisheries remain at a low level of fishing efforts. {I}t is apparent that catch per unit effort ({CPUE}) is exponentially correlated to the size of the fishing area. {E}valuation of historical catch and effort data show that fishery yields at {P}aama are beginning to respond to the impact of effort. {E}stimates of yearly unexploited unexploitable biomass based on the rates of decline in {CPUE} varied from 32 to 57tons in {P}aama and 21 to 36 in {A}mbae. {A}llen's (1984) model was used for these estimates on rates of natural mortality from 0.25 to 0.50. {F}or an age of recruitment of three years, and a natural mortality of 0.25, ranges of maximal sustainable yield are between 3.4 to 18.3 tons in {P}aama and between 2.2 and 11.5 tons in {A}mbae. {A}s annual recorded catches are actually higher without a significant decline in annual catch, this suggests that equilibrium has yet to be achieved. {E}xtrapolation of estimated catch rates per nautical mile of 200 meters isobath (where most fish occurs), to the entire number of nautical miles present in {V}anuatu at this depth suggests that maximum sustainable yield isbetween 113.2 to 603.5 tons/year. {T}his biomass could sustain the full time operation of a fleet of 17 to 100 boats, fishing 120 to 150 days per boat/year.
