Settlement Of Marine Boring Bivalve Larvae On Wood Soaked Horizontally And Vertically In West Java

By: Fredinan Yulianda

Pieces of red meranti wood (Shorea leprosula) were soaked in horizontal and vertical positions in sea waterfor 9 weeks. Two species of bivalves settled on the wood: Bankia campanellata (Moll & Roch) and Martesia striata (Linné). Average densities of settling larvae were 125 ind 100 cm-2on horizontal wood, and 95 ind 100 cm-2on vertical wood, indicating a tendency to settle on the top side of the wood. The number of larvae settling on wood immersed at the surface was not significantly different from wood at 1.25 m depth.
