Regarding Penobscot Bay Aquaculture initiatives

Appleton citizen Randall Parr addresses common concerns about the proposal for land based salmon farming

Apprehensions been voiced about land-based Atlantic Salmon farms proposed near Penobscot Bay.

In their aquatic environment over 95 percent of baby wild salmon die before adulthood, while most of those in salmon farms fed copious amounts of food without predation should live through maturity.

Fish oil, which fresh Salmon when eaten as food provide, contain Omega-3 fatty acids that help heart and circulatory systems is prescribed by doctors to reduce risk of coronary heart disease, the leading cause of death for humankind. Salmon also contain Vitamin D, Riboflavin, Calcium, Phosphorus, Iron,  Zinc, Iodine, Magnesium, and Potassium. The American Heart Association recommends eating fish at least twice a week as part of a healthy diet.

Concerns were raised about the quantity of water Salmon farms would extract to circulate in fish tanks from wells in Belfast. Copious rainfalls in recent years continue to amply recharge aquifers in coastal Maine, and unlimited seawater is available for desalinization for land-based fish farms.

Land-based Atlantic Salmon farms can be expected to increase jobs, incomes, sales, tax revenues, and economic activity. These projects should expand the economy, reduce youth out-migration which has bedeviled Maine for decades, keep small businesses alive, and workers busy.

Fecal discharges through underwater pipes extending into Penobscot Bay from shore in Belfast has  been another concern of citizens. Predicted waste pipe contents have not yet been made public, but filtered salmon excrement is expected to be its principle contents. Due to over-fishing and other reasons, wild Haddock, Cod, Swordfish, Tuna, Atlantic Salmon and other Penobscot Bay fish populations have fallen in recent years, reducing the natural recurrence of fish excrement in the water.

Fish poop augments water plant propagation like fertilizer stimulates vegetable growth on land. Containing nitrogen and nutrients, fish waste nourishes species at the bottom of the food chain, which sustains fish and sea creatures that eat them and others that feed on them.

Chlorophyll-containing green water plants also photosynthesize oxygen from carbon dioxide in seawater so that fish can absorb it through their gills into their bloodstreams like mammals do from air through our lungs. If current aquaculture initiatives pan out, wild Cod, Haddock, Tuna and Swordfish poop reduction, due to decline of these species may be offset by farmed Salmon waste, which could increase sea life in the bay and make wild fish more abundant.

Some are afraid that forest wild life habitat will be clear cut to build this facility. Citizens should participate in this process to prevent that.

We should encourage these initiatives but ensure they have positive environmental impacts by participating in the process.
