Abstract

This study was conducted to find out location which was suitable for culture of grouper (Epinephelus sp.) in Pulau-Pulau Sembilan waters, Sinjai Regency, South Sulawesi. The primary data were collected from each study areas as grouper culture requirement i.e: coastal topography, from the high wave and current, water quality and biological parameters. Secondary data such as wheather, coastal fisheries production, tide probability, Indonesia earth surface map of Sinjai area scale of 1: 75,000, landsat imagery-7ETM digital product and navigation map scale 1: 200,000 were collected before the study. Thematic map of area, suitability as the main expected output of the study was made through spatial analysis and Geographical Information System (GIS). The site suitability for grouper culture in floating net cage was evaluated based on the physical oceanography as limited factors, where factors which influences to the grouper growth and survival were given highest value.The range of values was 0-1. The level of suitability at the value of 1-4, where 4 (100%) = S1 (most suitable), 3 (75-99%) = S2 (suitable), 2(50-74%) = S3 (fair suitable) and 1 (< 50%) = N (less suitable). The potential areas which were suitable for grouper culture in floating net cage development was 303.4 hectares.

Abstract

The objectives of this research were to find out the distribution and abundance of macrozoobenthos in Kupang Bay and to evaluate the suitability of this water for mariculture activity in the future based on physical and chemical water properties. Samples were collected from 10 stations along shoreline of the bay. Water samples were collected by cammerer water sampler, while benthic organisms were collected by ekman dradge. Samples were transferred to laboratory to identify and analyze. The results showed that the diversity index of the macrozoobenthos was moderately stable, and there were 4 to 10 species found in each station of Kupang Bay. The species dominancy was ranged from 28-82%, and the most dominant was Nassarius pullus. The water quality indicated that the study site was suitable for mariculture activities. It leads to suggestion that for the seaweed and floating net cage culture should be located in the mouth of the bay, while for pearl culture should be located along channel between Semau and Timor Islands.
