Synopsis (short abstract) The report provides an assessment based principally on the sampling of catches at the Mukalla Cold Store and associated landing sites during the three seasons from and including 1980/81. Cohort identities were established using the method of Bhattacharya. Spawning was concluded as occurring twice each year; in the month prior to February and again sometime between May and October. Yield per recruit analyses indicated that modest increases in annual catch would result from increasing the fishing mortality coefficient. To the extent of 6% more catch if the fishing mortality coefficient was increased by 25%; and 13% if the latter was increased by 67%. It was suggested that management action to seek these increases in annual catch might not be justified, particularly if associated with the introduction of substantial additional costs. In respect to the adjacent: fisheries for lobster, that: associated with the Thabut Cold Store was considered near to being fully exploited, while substantia l additional catch was suggested as possible from the fishery at Socotra.
