SOUND OF PADDLE WHEEL ON SEA BASS GROWTH
Abstract: The objective of
this research is sound effect for brackish water for Sea bass (Cynoscion
nobilis). Breeding farm 25x100m, 2m of depth, and 6 paddle wheels which
generate the sound are available for research. Sound profile has been measured
to investigate the amplitude at various measurement points at various depths by
using Cetacean hydrophone C304. The output of hydrophone has been analyzed by
using SpectraPlus software. For the second measurement, two cages which size
3x3m have been used for life fish habitat. Then, fish put in the edge cage
(20), center cage (20), and out of cage (12500). Sound profile has been
measured for position-based (edge/center cage), time-based
(morning/noon/evening), and point-based. Time series, spectrum frequency, and
phase have been analysis. Fish growth progress has been monthly measured at
every cage. Fish in the cage is growth as linearly, while fish growth for out
of cage is exponentially. Size and weight of fish in the both cages is less than
out of cage. This research concludes that sound have no significantly effect
for fish growth. Limited mobility to look for food and stress are more
influences to fish growth than sound effect.
