ABSTRACT

The principle
objective of this project was to reintroduce trochus,
a high-valued shell is used in cosmetic, paint elements,
and other luxury clothing items (e.g. buttons), to the
outer islands of Yap State. In doing this, it is anticipated
that a commercial harvest will ensure and this will provide
additional income revenue generating opportunities for
island residents. The project activities concentrated
on seeding adult trochus (four inches in diameter from
the widest base of the shell) to four island groups (Elato,
Lamotrek, Ifalik and Faraulap). A total of three
different seeding trips were undertaken on regularly scheduled
commercial merchant inter-island vessel. All the broad
stock was collected from Woleai reef. Yap State Marine
Resources Management Division (YMRMD) staff worked along
with the outer island communities in collection and transplanting
of the adult trochus. Typically, 1,500 adult trochus were
transported in live wells placed on the vessels and trochus
were dispersed upon arrival at a planning site. An additional
fourth trip was made to assess all newly seeded sites.
The results were found to be very positive. At present
it appears as though the transplating occurred with a
high survival rate. There were not any significant problems
that impacted project goals and objectives. It is impossible
to say what the future holds regarding the commercial
harvesting in the recently seeded islands. Therefore,
it is imperative to continue monitoring and management
of all trochus sites. This can be done through transect
line surveys. It may also be worthwhile to consider the
possibility of YMRMD transplanting adult trochus to other
outer islands in Yap State.
