After returning to the dock in Paredon Colorado, Jose Antonio Salido (38, right) and his father,
Jose Maria Salido (64, left), collect fish they've caught in Tobari Bay from their nets. According to Stanford researchers that studied five years of satellite data, it is usually just a few days after excess irrigation water enters the sea until the Sea of Cortez errupts in an artificially induced Algal bloom. These can cover from 19 to 223 square miles, raising concerns about the ecosystem's health and the impact on the fishing industry.
