Description The heavy demand, concomitant with specific expldltattoti as
welt as bottom trawling led to habitat destruction and depletion oj
sacred chank Xancus pyrum. Experiments conducted to study the
natural growth and breeding aspects indicate that during March
and November, the chanks release egg capsules containing fertilised
eggs. The deuelopment is direct and the babies hatch out after 32
to 35 days of incubation at an ambient temperature 30.7°C. During
their early stages, they feed on oligochaete and polychaete worms.
From an initial 9.09 mm, they grow to 62.23mm In an year, while
the MSD increased to 27.40 mm. They weighedfrom 0,14 to 32.36 g
during one year. Chanks are non-migratory and their natural growth
in sea indicated an average MSD growth ofS.Omm/yearforXancus
pyrum var. acuta.
