This project gather underwater noise generated by fishing vessel type B inboard
engine with different horse power and outboard engine used by coastal fisher. Artificial
sound produce by the shipping and industrial activities are affecting the behaviour of
marine life. The objectives include investigating underwater noise characteristics of
propeller (level, frequency and noise spectrum intensity) and study the impact of
underwater noise towards environment. The generated noise will be collected at
Seberang Takir, Kuala Terengganu (fish landing place), jetties using underwater
recording system (C55 hydrophone, PA amplifier, Foster FR digital recorder). The noise
generated will be analyzed by Raven Pro software. High level underwater noise affect
the marine life in particular marine mammals and certain fish types.
