Abstract
    A study of the distribution and abundance of the juvenile top shell, Trochus niloticus occurring on intertidal flats off the East Coast of Kei Besar Island, Indonesia, was performed. An analysis of 2 transects collected at low and high tides showed an occurrence of 6 % at low tide and 14 % at high tide of all gastropods sampled. The average density of juvenile Trochus was 0.55 ind/m super(2) at one site while juvenile Trochus were absent at another site. Adult Trochus were found at both sites. A total of 37 species of juvenile molluscs (33 gastropod species and 4 bivalve species) co-occurred with juvenile Trochus. Factors regulating the distribution and abundance of T. niloticus are discussed.
