Hypoxia, a condition where oxygen levels are insufficient for maintaining normal biological function, is indeed a deadly trap for these Menhaden fish.
When ensnared in hypoxic waters, fish become erratic, further depleting their oxygen reserves and culminating in mass fatalities, as observed at Freeport’s Bryan Beach.
Cloudy Skies and the Depletion of Oxygen
The recent cloudy weather has further compounded the problem.
Oxygen levels in the water are partly sustained by the photosynthetic activities of microscopic phytoplankton and macroalgae.
With overcast skies inhibiting sunlight, the production of oxygen via photosynthesis is diminished, hence contributing to the lowered oxygen levels and the plight of the Menhaden.
Cleanup Efforts Underway
Cleanup crews have already been mobilized to the area, aiming to remove the extensive carpet of deceased fish from the beaches.
The process, however, is arduous and contingent on the tide receding several feet further.
Quintana pedestrian beach is slated for a thorough cleaning come Sunday, with public beaches following suit the day after.
