The oligochaetes worms were cultured in five different diet treatments (commercial pellet, seaweed, goat dung, soybean meal and combination diet) each having triplicates. The oligochaetes were cultured for 90 days. The highest survival rate of oligochaetes culture were found significant (p < 0.001) in the combined diet containing goat dung (20%), seaweed (Gracilaria sp.: 20%) and soybean meal (20%). Results of the present study suggest that the combination diet is the best compared to single diet in order to obtain the maximum survival rate of marine oligochaetes worm. The present finding is important in providing the baseline data for marine oligochaetes culture. Further study might be extended in detail to investigate the reproductive cycle since marine oligochaetes is highly potential in mass culture production.

Bivalve samples and environmental parameters (in situ parameters and sediments) were collected from 11 stations within 50 m transect line along the lagoon. A total of 10, 845 individual of bivalves were collected and classified into 11 families, 21 genera and 34 species with mean total density of 33±17 individuals/m. 2 There was no significant temporal changes in abundance of bivalves and environmental parameter (p>0.05). The density of bivalves, in situ parameters (salinity and pH) and sediment analysis (total organic matter and sediment size) had significant difference among stations (p<0.05). However, density of bivalves had no significant relationship with all environmental parameters studied (p>0.05). Density of bivalves was higher in the brackish subtidal area compared to freshwater subtidal and mangrove intertidal area. The abundance of bivalve's species in the lagoon area of Setiu Wetlands is relatively high to the area covered. Salinity was the only parameter that strongly correlated with the diversity of bivalves in the lagoon area of Setiu Wetlands.

This study aimed to determine the intertidal macrobenthic horizontal distribution and their relationship with environmental parameters. An analysis of the intertidal flat marobenthos community suggested that polychaetes dominated the community in terms of the number of individuals and species followed by crustaceans and molluscs. Polychaetes of families Nephtyidae, Spionidae, Capitellidae, and Magelonidae contributed to the high densities of macrobenthos. Multivariate analysis performed by the Biotic and Environmental linking analysis indicated that communities in Transect 1 and Transect 2 were best correlated with food availability (sediment chlorophyll a), and heterogeneity of sediment type (percentage of fine sand and very fine sand). Heterogeneity of sediment characteristic and food availability were identified as potentially playing a key role in the shaping of the intertidal macrobenthic distribution in Buntal Bay.

The study on macrofauna community structure in seagrass meadows at Sampadi Island, Sarawak was conducted in October 2012. The objectives were to determine the macrofauna community structure and its relation with physico-chemical parameters of the water in Sampadi Island. A transect line was laid down from high to low tide marks on the intertidal area of the island. A 0.25 m-2 quadrat was used to sample the sediment and sieved using the 500 µm sieve. The macrofauna retained on 500 µm sieve were identified in the laboratory using various keys in the literature with the aid of stereo- and compound microscope. Five macrofauna phyla were recorded in the seagrass meadows, namely Mollusca (Cardiidae & Veneridae), Annelida (Dorvillea sp., Eulalia sp., Eteone sp., Cirriformia sp. & Tubificoides sp.), Sipuncula (Sipunculidae), Arthropoda (Alpheus sp., Harpacticus sp. & Colomastix sp.) and Chordata (Branchiostoma sp.). The community structure of macrofauna in seagrass meadows of Sampadi Island was influenced by the dissolved oxygen, sediment grain size, salinity and temperature.

The lagoon is mainly surrounded by the mangrove stand and comprises others unique inter-connected ecosystem including sandy beach, coastal forest, seagrass beds, river and islands . Brachyuran crabs (true crab) belong to infraorder Brachyuran.
