Blooms regularly appear briefly in the Strait of Georgia and are lasting longer.
Phytoplankton blooms the colour of cream of tomato soup along the shores of Vancouver Island are becoming more common, likely due to hotter weather, scientists say.It’s the result of a phytoplankton called noctiluca, which occurs with the right combination of nutrients in the water and hot weather, said Svetlana Esenkulova, a biologist with the Pacific Salmon Foundation who is trying to determine if the phytoplankton is harming salmon.
The organisms contain ammonium and it’s possible they can affect marine life when they decompose, Esenkulova said. “From that, you get this breakdown product of ammonium. So, when the bloom is really big, there’s a lot in the water, most fish swim away,” she said.
