ABSTRACT
The rates of sedimentation and growth of the branching coral
Acropora formosa at Marine Park, Tulai and Renggis
reefs in Tioman Island, Malaysia were surveyed between November 2000 and
October 2001. The sedimentation rates were measured using sediment traps and
the coral growth rates were measured using digital photography and computer
image analysis. The rates of sedimentation at Marine Park (17.3 ± 18.7 mg dry
weight cm-2 d-1) were 5.0 times higher than the
Tulai site and 11.4 times higher than the Renggis site. In contrast, both the
linear extension (3.9 ± 0.9 mm month-1) and areal growth rates (3.9
± 1.7 cm2 month-1) of A. formosa at Marine Park were significantly less than at Tulai and Renggis. The higher
sedimentation and consequent lowered light levels at Marine Park may have
resulted in the lower growth of the Acropora corals.
Keywords: Branching coral; linear extension growth; sedimentation;

ABSTRAK
Kadar pemendapan dan tumbesaran karang reranting Acropora formosa
di sekitar terumbu karang kawasan Taman Laut, Pulau Tulai dan Pulau Renggis di
persekitaran Pulau Tioman, Malaysia, telah diselidik antara bulan November 2000
dan Oktober 2001. Kadar pemendapan diukur dengan menggunakan
perangkap mendapan dan tumbesaran karang dinilai dengan menggunakan imej
digital dan perisian komputer. Kadar pemendapan di tapak Taman Laut
(17.3 ± 18.7 mg berat kering cm-2 h-1)
adalah 5.0 kali ganda lebih tinggi berbanding tapak di Pulau Tulai dan 11.4
kali ganda lebih tinggi dari tapak di Pulau Renggis. Sebaliknya, pertumbuhan
linear (3.9 ± 0.9 mm bulan-1) dan kadar pertumbuhan permukaan (3.9 ± 1.7 cm2 bulan-1) A. famosa adalah
lebih rendah secara bererti di Taman Laut berbanding Pulau Tulai dan Renggis.
Kadar pemendapan dan seterusnya pengurangan penembusan cahaya di Taman Laut
mungkin menyebabkan kemunduran kadar pertumbuhan
karang Acropora di tapak kajian.
Kata kunci: Kadar pertumbuhan linear; karang
reranting; pemendapan; Pulau Tioman
