Abstract

Between 1989 and 1992, small-scale grow-out trials of cultured Tridacna gigas (L.) were established at 40 coastal villages in Solomon Islands. The juvenile giant clams were delivered to village participants ata mean size of 34.6 mm shell length (SL) and a mean age of 380 days. The clams were grown in cages of wire mesh placed on trestles in shallow, subtidal, coral reef habitats. After a mean grow-out period of 297days, the clams were a mean size of 77.6 mm SL, a suitable size for sale to the aquarium market. Mean growth rate was 4.1 mn month(-1) In 32 of the 53 cages involved in the trials, all clams were removed completely from the cage every 3 months for cleaning, The mean survival rate of these clams was 54%. The clams in the remaining 21 cages were notremoved for cleaning and their survival was significantly lower (22%). The growth rate of clams removed for cleaning (3.7 mm month(-1)) was, however, significantly lower than the growth rate of undisturbed clams (4.8 mm month(-1)). At current prices for juvenile T. gigas in the aquarium trade, farmers who regularly cleaned clams would have netted a minimum of US$180 for a cage initially stocked with 390 clams. Farmers who did not clean their clams would have netted only US$40 per cagedue to poorer survival.
