Abstract:
Variety in video sampling protocol for coral reef survey in many countries has
prompted this study to create an optimised protocol for Coral Video Transect (CVT)
technique. In this study, CVT technique was evaluated at Bidong and Redang Island,
Terengganu. The aims of study was to optimise CVT technique for reef surveys and
the results of optimized CVT was compared to those conventional Line Intercept
Transect (LIT) technique. The effect of different vertical distance of camera above
the substrate during video recording (1.0m, 0.5m and 0.2m), number of frames (20%,
30%, 50%, 80% and 100% frames extracted from 20m transect) and points analyzed
(5, 10, 20, 30, 50, 75, 100, 150, and 300 points per frame) during Coral Point Count
with Excel Extension (CPCe) analysis as well as time spent for fieldwork and
analysis were examined to decide the best approach to conduct CVT technique at
different coral reef conditions (good, moderate and poor reef condition).
