KEPADATAN DAN BIOMASSA CACING DIOPATRA SPP DI SEPANJANG SUNGAI SAPUREGEL SEGARA ANAKAN CILACAP
ABSTRACT: Sapuregel is a river
located in East Pelawangan Area Segara Anakan, Cilacap. This river become good live
habitat for benthos animal, one of them was Diopatra spp. worm. Diopatra spp.
worm by society used as bait in fishing and natural fool for fish and shrimp.
This research that ”Density and Biomass of Diopatra spp. Worm along Sapuregel
River Segara Anakan, Cilacap”. This research had been done at April until Mei
2007. The aim of this research are to know density and biomass of Diopatra spp.
worm. also relation density biomass of Diopatra spp. worm between station. A
survey was done by Group Random Sampling. Research location is divided into
five stations according to difference of environment condition. Each stations
collected nine points randomly of three times with time interval of 1 week. And
then the data were analysed by F test and Correlation Regression test. Research
result showed that density of Diopatra spp. worm in station I, II, III, IV and V
were 5, 22, 10, 18 and 10 ind/m2, with high density Diopatra spp. worm in
station II and low density in station I. Biomass in station I, II, III, IV and
V were 11,59; 60,61; 24,46; 53,61 and 31,68 g/m2, with high biomass Diopatra
spp. worm in station II and low biomass in station I. F test result shows that
there was significant differences between stations based on density and
biomass. Result of regression test of density and biomass between station
showed positive correlation and thigh correlation with value of 95,93% means
that higher density value then their biomass value also higher.
