I've been doing some wikipedia binging and it's come to my realization that it may be in the Earth's best interest to raise the world oyster population as quickly as possible. The basis for this is for several reasons:
[They hold] promise for relieving pressure on land-based protein sources.
[They] provide shoreline protection and sediment stabilization, nutrient cycling and sequestration, and habitat for other organisms.
and most importantly:
sources state that a single oyster can filter 24–96 liters a day (1–4 liters per hour). With 750,000 oysters in one acre, 18,000,000-72,000,000 liters of water can be filtered, removing most forms of particulate matter suspended in the water column. (Source)
What I'm curious about, however, is the potential downstream impacts of the overpopulation of oysters. They seem to have so many ecological benefits, I'd like to see if there's a hard detriment to everyone breeding thousands of oysters in their free time to help the ocean.
What I'm particularly concerned about is other filter feeders that may become threatened by a strong prevalence of the oyster population.
To summarize my question; is this a reasonable solution, and what potential risks exist should the world try to greatly increase the oyster populations where they exist currently already?
As @Fred pointed out in the comments, precautions would/should be taken to ensure endemic oysters are used to be as minimally invasive as possible, and responsibly bred for biodiversity to prevent viral catastrophe.
