Harmful Algal Bloom

The Quinault Division of Natural Resources is keeping an eye on the ocean for blue-green algae.

The Quinault Indian Nation’s Harmful Algal Bloom (HAB) monitoring project allows the Nation to detect harmful algal blooms in the ocean.

An HAB is the rapid and uncontrolled growth of algae in either freshwater or marine environments. Because some algae produce toxins, such as domoic acid, they can be harmful to humans, mammals, birds and fish when they are ingested. As blooms grow, they deplete the oxygen in the water and block sunlight from reaching fish and plants.

HAB’s can last from a few days to many months. After the bloom dies, the microbes which decompose the dead algae use up even more of the oxygen, which can create fish die-offs. When these zones of depleted oxygen cover a large area for an extended period of time neither fish nor plants are able to survive.

Among the causes of HABs are high-nutrient conditions in water, mostly of nitrates and phosphorus which are emitted by agriculture and other industries. Higher water temperature and less circulation are also factors. HABs can cause significant harm to animals, the environment and economies

Working with the QDNR Fisheries Department we have developed local laboratory techniques to test shellfish in Taholah rather than depend on labs in Seattle.

“This is my land
From the time of the first Moon till the time of the last Sun
It was given to my People
Wha-neh Wha-neh, the great giver of life, made me out of the Earth of this land
He said, ‘You are the land, and the land is you’
I take well care of this land, for I am part of it....”
