Abstract

The exploitation level of fish resources should be based on effectiveness, efficiency and business sustainability. One of the efforts to implement these three aspects is to understand the seasonal pattern or the best time to catch the fish target. The aim of this research was to estimate the pattern of the anchovy fishing season based on production data landed at PPI Paotere Makassar, South Sulawesi. Data is collected from the PPI and analyzed using the moving average techniques. Results showed that the seasonal pattern of anchovy fishing is estimated to increase in the transition season to the eastern season (IMP > 100%) and reach a peak in September (IMP = 134.74%). Descriptively, the fishing season, especially the peak season, was thought to occur because these fish are probably associated with optimum conditions for oceanographic parameters such as sea surface temperature, chlorophyll-a concentrations and surface current conditions. Information on anchovy fishing season patterns is really needed by marine fisheries managers, both government and private, in managing efforts to exploit fish resources wisely and sustainably.

Abstract

The objective of this study is to characterize benthic substrate of Bonetambung reef area using worldview 2 highresolution satellite imagery. About 14.273 depth spot were deploy to build bathimetric model of the study area. The correlation of pixel radiance value from satellite imagery and depth value from field measurement werebecame the basis to classify geomorphologic zone of shallow water area up to 7 meter depth. Between threeinterpolator tested, the natural neighbor interpolator has produced the best bathymetric model with root meansquare error 0.3 meter and benthic substrate coverage model with thematic accuracy 62%. These approach beable to recognize four substrate type in general, such as sand, seagrass, rubble and coral. Geomorphicsegmentation based on bathymetric profile and radiance value of worldview 2 imagery may also maps the reefflat, reef slope and lagoon area hence may support the benthic substrate modeling. This study showed us apotential technic to develop a modelling for juvenile fish transport at Bonetambung coral waters.Key words: benthic substrate bathymetry, worldview imagery, thematic accuracy

Abstract

Basic of zoooplankton dependence on the phytoplankton to fulfill the requirement energy needs and creates acomplex relationship. The relationship of dependency between fitoplankton and zooplankton are very close,eventually can cause the changing in the zooplankton density in the time and space. The aims of study toaanalyze the changes in the zooplankton density on the phytoplankton abundance based on various time anddepth in the waters Badi Island of Pangkep Regency. The research has been carried out December 2009 toApril 2010. The results showed that changes in zooplankton density, not only because of the phytoplanktonabundance but also due to other factors such as sunlight. Keywords : density, abundance, zooplankton, phytoplankton, Badi Island
