Make it count: maximising the stocking density of juvenile fluted giant clams (Tridacna squamosa Lamarck) during simulated live transportation

Juvenile giant clams are usually transported at stocking densities of 1-2 bag¯¹ for up to 48 hr. In this study the effect of stocking juvenile fluted giant clams (Tridacna squamosa) at densities ranging from 2-19 bag¯¹ were assessed. Juveniles ranging from 50-70 mm in shell length (SL) and 11.3- 39....
