Raw or poorly treated sewerage can spread disease, contaminate shellfish beds and lower the oxygen levels in the water. Waterborne diseases including hepatitis, typhoid and cholera can be transmitted by shellfish. And as a result, the sewerage in the water may deplete the water's oxygen level, causing stress to fish and other aquatic animals. Added nutrients can also accelerate oxygen depletion in the water by stimulating uncontrolled plant growth, called eutrophication, which can contribute to algal blooms, foul odors and fish kills. This problem becomes more significant in enclosed harbors where boaters concentrate to anchor, swim, and fish Shellfish are filter feeders that eat tiny food particles filtered through their gills into their stomachs, along with the bacteria from sewerage.
