are minimal and stagnation occurs, he said. Over-abundant algae and other microorganisms that thrive in nitrogen-rich waters can produce low-oxygen conditions that suffocate finfish and shellfish. Co-authors of the new paper are Dr. Jerad D. Bales of...
Study finds wind, currents play key role where young fish settle

may cause fluctuations in the size of fish populations along the entire Gulf coast. Using a computer model to simulate the exchange of water and fish larvae through Aransas Pass, researchers found that many of the "fish larvae" settled in an area of ...
