【 摘 要 】

The existence of Harmful Algae Blooms (HABs) can adversely affect the water like a mass death of fish and oxygen depletion. Some types of HABs can be contaminated with seafood and contain biotoxins that are detrimental to the health of humans who consume them. Green mussels (Perna viridis) has the properties of filter feeders so vulnerable to contamination HABs. This research was conducted to produce spatially thematic maps contaminated HABs in P. viridis so providing information about risk prediction P. viridis when consumed by humans. Sampling was done purposively in three (3) stations that represent the Bay Semarang namely western boundary waters (Kendal), middle (Semarang) and the eastern boundary (Demak). Sampling done two (2) times, namely East season (June-July) and the second transitional season (September) 2016. Analysis of HABs done either in water or body tissues of P. viridis through the analysis of food habit. The results shows that P. viridis genus positive contaminated HABs phytoplankton Tricodesmium and Ceratium. Spatial distribution and abundance of Tricodesmium genus Fitoplankton is wider and taller than the HABs Phytoplankton genus Ceratium. Group HABs are found in the tissues of P. viridis no potential as biotoxin that does not cause adverse health risks.
