ANALISIS BEBAN LIMBAH DAN PENGAYAAN NUTRIEN PADA KEGIATAN KERAMBA JARING APUNG DI PERAIRAN PULAU PANGGANG DAN PRAMUKA, KABUPATEN KEPULAUAN SERIBU
ABSTRACT: Series of
measurements of organic load from marine fish farm activities were conducted in
different time frames to see predicted changes to the water columns and
sediment condition. Earlier hydrodynamic model predicted a linear impacts of
organic pollution to both environments due to growing fish farm activities in
addition to anthropogenic pressures from surrounding islands. This research was
aimed at analyzing temporal changes taking place at the site and mapping
spatial impacts of organic loads released from the fish farm to the surrounding
waters. The results suggested that changes did take place but are not as severe
as predicted since topography of the areas and geomorphology of the environment
in addition to the natural flushing mechanisms have helped sweep away
accumulated nutrients. Analysis of biology and physical matters of the marine
water and sediment showed that there is no significant changes through time.
Spatial impact are detected but to the degree that are tolerated by the environment.
Coral condition and fish abundance are not impacted. Since the surrounding
environments are nutrient-poor, a number of organisms might have consumed
nutrients released from the farm. Predicted eutrophication and other negative
impacts did not take place. Therefore environmental management of the is needed
to quantify impacts in the future.
