Abstract

The sea cucumber stocks off the east and northwest coasts of Sri Lanka were estimated bysurveying 1307 km2 and 1779 km2 by an underwater visual census (UVC)in June and October 2008 respectively. The presence of twenty-five sea cucumber speciesbelonging to seven genera; Actinopyga, Bohadschia, Holothuria, Pearsonothuria,Stichopus, Thelenota and Acaudina was identified in fivehundred sampling sites randomly selected in each area. The overall average density (± SD) of sea cucumbers was higher in the northwest (350 ± 648 ind ha-1) than inthe east (90 ± 130 ind ha-1) and low-value species were predominant in bothsurvey areas (79 ± 125 ind ha-1 in the east, 244 ± 488 in the northwest) whencompared with medium (10 ± 34 ind ha-1, 105 ± 175 ind ha-1,respectively) and high-value category (<2 ind ha-1).The estimated total biomass in the northwest (13 024 t) was roughly four times greaterthan the east (3027 t). Holothuria edulis was the most abundant speciesin numbers while Holothuria atra had the highest stock biomass in bothareas. Sea cucumber densities were significantly different among the habitat(p < 0.001) and depth categories. The highestdensity was reported in rocky habitat associated with seagrass and / or macroalgae. Thedensity of low-value species was significantly high in 1–10 m depth category(p < 0.001) in the northwest while othercommercial groups were dominant in 20–30 m depth range in both areas. Temporal banning ofthe fishery for high and medium-value species would be a better management option to avoidfurther stock depletion.
