Abstract

The spatial distribution of the water productivity bio-optically can be identifiedand detected by using visible infrared sensor of Coastal Zone Color Scanner(CZCS) carried by the satellite Nimbus 7. Since the availability of the ADEOS(Advance Earth Observation Satellite) that carried both sensors of the visiblenear infrared and near infra red on the OCTS (Ocean Color andTemperature Scanner) in August 1996, beside the water productivity,the fishing ground also is hoped can be studied all at once by using twoidentification methods of the SST ( Sea Surface Temperature) and OceanColor.

Abstract

Environmental parameters of Hurun Bay estuary were monitored at the site of13.5 m3 floating net cages for Epinephelus cromileptes in July 2003. Averagedissolved oxygen inside cages was 3.68 – 6.76 ( average 5.35) mg/L with watertemperature 28.64 – 29.72 (29.09) oC. Salinity 32.69 – 33.0 (32.94) psu andturbidity 0.27 – 13.62 ( 1.15) NTU. Inflow rate of cages was 72 m3/hr withcurrent velocity 2.3 - 5.1 cm/s. Results showed that the functions of respirationrate for correlation between respiration of E. cromileptes and their weight wasy = 0.0065x + 0.1202 meanwhile the functions of optimum stocking density wasY = 1170.7 X -0.5648. On basis of dissolved oxygen budged, estimated optimum stocking density for lower limit was 128 ind/m3 for fish 50 g in average, 60 ind/m3 for fish 200 g and 21 ind/m3 for fish up to 1200 g.

Abstract

A study of the role of habitat complexity and predation on the composition ofthe macroinvertebrate community in a small dystrophic wetland wasundertaken using artificial substrates. Rectangular samplers of increasingcomplexity were constructed from nylon mesh and wooden dowelling.Samplers of three levels of complexity were developed in both caged anduncaged forms to evaluate the effects of substrate complexity and predationon macroinvertebrate richness and abundance. A total of 24 samplers (6treatments x 4 relicates were deployed in swamp for 8 weeks in September/November 1995. The results indicated that increased habitat complexity doeslead to species richness, but cages have an effect in addition to layers aspreferred habitat for both prey and predator. Increasing richness is not followedby an increase in abundance in more complex habitats. However, an increasein habitat complexity tended to result in a decrease in abundance, probablydue to predation with the lowest abundance found at intermediate compexity.

Abstract

Many estuary have a different salinity distribution, influence for the differentlevel of tide, river discharge flow, velocity and current direction. Januari 2006 at Delta Mahakam, going to salinity measurement activity covered by four village closed to the sea, that is Kersik, Marang Kayu, Muara Jawa and Muara Kembang. Water deep at Delta Mahakam relatif shallow, around 0.5 – 9 meter. Every estuary founded 2 – 5 point measurement salinity from the surface water until bottom and found the different for the salinity distribution. Kersik region have a higher salinity until 30 psu, whereas at the Muara Kembang region salinity level only 12 psu with a distance from the coast line about 3 km. This location similar with the Muara Jawa region. Pattern circulation and stratification water estuary base for clasification, Marang Kayu region have a mix completelly or vertical homogeneous estuary, while a Kersik, Muara Kembang and Muara Jawa region have a moderat sratification estuary. This type is very common in Indonesia, fresh water flow throungh to the river very dominant at several estuary.
