Abstract

Research on the diversity of invertebrate epifaunas associating with mangroves in the Balangdatu village of Tanakeke regency, Takalar district, South Sulawesi, has been conducted from September to December 2016. The objective of this research was to know the diversity of invertebrate epifaunas associating with mangrove in Balangdatu Village of Tanakeke Islands. Sample collection was done by using explorative quantitatively plot methods with size 2 x 2 m, applied at three different stations. Data analysis includes calculation of Absolute density, Uniformity Index (Shannon-wiener), Dominance Index, and Distribution Index. The results showed that there were 13 species of epi fauna of 9 tribes, namely Littoraria sp 1, Cerithidea cingulata, Littoraria sp 2, Littoraria pallescens, Episesarma sp, Saccostrea cucullata, Pagurus sp, Terebralia sulcata, Cerithidea sp, Nerita planospira, Nisto histrio, Littoraria scabra, and Cassidula vespertilionis. The highest density was found in Littoraria scabra with a density of 0.72 ind/m2. Diversity indices are low which indicate depressed environmental conditions. Distribution Index values across stations <1 indicating that the pattern of individual dispersion tends to be uniform.

Abstract

Corn oil is an essential fatty acid containing linoleic acid (n-6). This study aims to evaluate the different doses of corn oil in the Artemia sp. enrichment on the growth and survival of tiger catfish (Pseudoplatystoma punctifer) larvae. Tiger catfish larvae (initial weight of 0.004 g) were reared in an aquarium (30x20x20 cm) with a volume of 9 L for 15 days. Enrichment using corn oil was carried out six times a day with an enrichment duration of 4 hours, and every 4 hours continuously in each day for feeding. Three treatments with different doses: P0 (control), P1 (0.075 mL/L corn oil), P2 (0.225 mL/L corn oil) with three replications were used in the present study. The results showed that the enrichment of Artemia sp. have significant effect (p<0.05) on the growth of tiger catfish larvae than control (without enrichment). Artemia sp. enrichment with corn oil dosage of 0.225 mL/L produced the best results on final weight (0.11g), final length (24.30 mm), absolute weight growth (0.1 g), absolute length growth (20.33 mm), specific growth rate of weight (28.13 %.g/day) and specific growth rate of length (15.04 %.mm/day) of tiger catfish larvae compared to other treatments.
