Abstract

Maluku as a major producer, reached the highest production of siput lola (T. niloticus) in 1989 with production about 250tons (6.8 billion) but then drastically decreased to 14.2 tons in 2005. This study was conducted over 16 months (March2012 - June 2013) in the waters of the Banda Islands. The purpose of the study was to determine the individual andpopulation growth of trochus snails. Individual growth rate (K) of siput lola resource for deameter basalt (DB) was equal to0.2439 (von Bertalanffy models) and 0.3571 (Gompertz models). Maximum size (S?) that could be achieved for deameterbasalt was equal to 91.73 mm (von Bertalanffy models) and 88.52 mm (Gompertz models). The population growth rate(r) of siput lola resource was at 0.1469 with a maximum amount that could be reached as many as 401 ind or 122ind ha-1 (von Bertalanffy models) and 191 ind or 58 ind ha-1 (Gompertz models) within a period of 24 months.Keywords : Growth, Trochus niloticus, Banda Naira islands

Abstract

Mangrove ecosystem has important role as source of nutrient particularly nitrogen in coastal area. Nitrogen (N) is alimiting factor in marine and coastal area. The aim of this research was to study benthic fluxes and potency ofbacterial activity in sediment of mangroves area, related to nitrogen cycle. This research was conducted in floodedmangroves area in Pulau Dua. The sediment and overlying water was sampled using sediment core sampler.Experimental treatment for flux analysis and sediment-slurry were conducted in three hours. Nutrient of NH3-N,NO2-N, and NO3-N and abundance of nitrifier, denitrifier, DNRA, and ammonifier were analyzed. The resultsshowed that the abundance of anaerobic bacteria was higher than aerobic bacteria. The dominance of bacterialgroups found in sediment was ammonification bacteria. The highest nutrient concentration in sediment was NH3-N. Benthic fluxes value showed higher NH3-N tends to release from the sediment to water than NO2-N and NO3-N. Generally, mangrove sediment in Pulau Dua has higher potency ofbacterial activity (Vmax and Km) in NO3reduction by anaerobic bacteria than NH3 oxidation by aerobic bacteria.Keywords: bacteria, benthic fluxes, mangrove, potency of bacterial activity, sediment
