Macrozoobenthos in vegetated area of seagrass had abundancy higher (0,070-0,085 ind/2738,06 cm3) than the un-vegetated area (0,035-0,067 ind/2738,06 cm3). This finding revealed by t-test that shown by accepted H1. It means a significant difference between the abundancy of macrozoobenthos in vegetated to un-vegetated areas. The number of species found in vegetated area by using corer in Doreri Bay was 113 species and in unvegetated area was 57 species.

This research was done on March-April 2014 at village of Akudiomi that was wellknown as Kwatisore in Nabire Regency at Papua Province. The research aimed to determine species composition, length-weigh relationship, local fishermen inventarization and mapping lobster fishing ground. Method used was descriptive with observation techniqu, sampling and interview. Also, the mapping and identification the correlation between physical oceanography parameters (temperature, salinity, depth and pH) on the fishing ground of lobster was to know the effect on the lobster availability. Resuls showed that during field observation, three species of lobsters were caught by fisheremen in Akudiomi that are P. versicolor for 111 individu, P. longipes and Thenus spp was 1 individu consecutively. The prediction of lobster growth pattern only done for P. versicolor as the dominant species caught in Akudiomi, that P. versicolor’ carapace length 8-13 and weight 250-1,097 gr/individu. Correlation between carapace length and weight of P.versicolor indicated positive with the same direction at 0.8636, (near 1). Analysis growth pattern P. versicolor showed , thus means or allometric negative (the growth of length faster than weight). Regression analysis indicated that temperature, depth, salinity and pH significantly affected the yield of lobster caught by fishermen in Akudiomi. Morevoer, oseanography aspects that had significant effect to caught of lobster temperature, salinity and pH.
