Filter Feeders At Work

Problem Statement:
 
"Several issues have substantially contributed to and exacerbated the impact of the increased human population.  Canals constructed with miles of seawalls free of mangroves , minimal or non-existent flow-thru/ water turn-over, and excessive depth, cannot naturally remove the constant onslaught of nutrient rich residential septic leachate, nutrient and hydrocarbon laden storm-water run-off, and increased construction activities. The severely limited circulation results in waterways with stratified layers, excessive organic loading, a deep heavy mat of sediment lining canal bottoms, a severe hypoxic or anoxic layer at the bottom, and documented pathogens hazardous to human and coral reef health including coliform bacteria and Serratia marcescens, a human sewage pathogen that has been linked to White Spot disease in elkhorn corals  (Acropora palmate) in the Florida Keys[i].
 
Solution:
 
By using systems that reintroduce and promote the growth and survivability of natural filter feeder organisms into the near-shore waterways, the negative impacts of the “Human Footprint” can be reversed in these waterways, bringing improved quality of life to Keys residents, ecosystems and improved fisheries populations.
