Red seaweed , one of the largest genus in Division Rhodophyta inhabits Sarawak coastal water. This study was designed to identify the species of using morphological approach and to assess selected water quality parameters in habitats. Three field samplings were carried out in Santubong and Asajaya, Sarawak from November 2013 to December 2014. Overall, three species were identified namely , and , attached to net of cage culture in Santubong and root of mangrove trees in Asajaya. In addition, three different taxa of aquatic macroinvertebrates (polychaete, small crab, bivalve) and single species of red seaweed ( sp.) were observed in assemblages. An estimate of 37% to 40% of the upper part of the cage net in Santubong was covered by seaweeds and only 16% to 20% in Asajaya's mangrove. The study had provided better information on identification of and their habitat in Sarawak. Future work involving DNA barcoding of each species is in progress.
红藻是红藻门中最大的属之一，栖息于砂拉越沿海水域。本研究旨在通过形态学方法鉴定红藻的种类，并评估其栖息地的选定水质参数。2013年11月至2014年12月期间，在砂拉越的三都望和阿萨贾亚进行了三次实地采样。总体而言，共鉴定出三种红藻，分别为[具体物种1]、[具体物种2]和[具体物种3]，它们附着在三都望的网箱养殖网和阿萨贾亚的红树林根部。此外，在这些组合中还观察到了三种不同类群的水生大型无脊椎动物（多毛类、小螃蟹、双壳类）和单一物种的红藻（[具体红藻物种]）。三都望网箱网上部约37%至40%被海藻覆盖，而在阿萨贾亚的红树林中仅为16%至20%。该研究为砂拉越红藻种类及其栖息地的鉴定提供了更好的信息。涉及对每个物种进行DNA条形码分析的未来工作正在进行中。
