Abstract

Red seaweed Gracilaria sp. is known as ‘Janggut Duyong’ by the local people of Sarawak. This macroalgae is
well-distributed in both temperate and tropical seawaters. Gracilaria sp. could be processed to produce agar for
industrial purposes whereas some people consumed it directly and become part of their daily diet. In terms of
ecology, Gracilaria sp. is one of primary producer in the seawater and its presence can form habitats to support
other aquatic organisms. Despite its socio-economic and ecological importance, little is known about Gracilaria
sp. in Sarawak. Hence, this study is designed to: (i) determine the diversity and abundance of Gracilaria in cage
culture of Lawas, Sarawak (ii) assess the water quality of the cage culture area where Gracilaria is found and
(iii) determine other aquatic organisms that found within Gracilaria population. Three field samplings had been
conducted from October 2013 to November 2014 at cage culture areas of Awat-Awat Village, Lawas, Sarawak.
Only single species of Gracilaria was found namely Gracilaria arcuata. Besides G. arcuata, Acanthophora sp.
and Padina sp. were also found but in small patches. In addition, five different groups of aquatic invertebrates
were observed namely tunicates, bivalves, polychaetes, small crabs and brittle stars. The selected water quality
parameters namely temperature, pH, dissolved oxygen, salinity, turbidity, total suspended solid, orthophosphate,
silicate and chlorophyll a were significantly different (p= 0.000) during all the three field samplings except for
nitrite (p= 0.588). However, the values recorded were within normal range of standard water quality for tropical
estuarine area. Since healthy population of Gracilaria could be easily found here, therefore this area has the
potential for future seaweed aquaculture.
