  • Salmon Migrate by Truck during California Drought

     In drought-stricken California, young Chinook salmon are hitting the road, not the river, to get to the Pacific Ocean. Millions of six-month-old smolts are hitching rides in tanker trucks because California's historic drought has depleted rivers and streams, making the annual migration to the ocean too dangerous for juvenile salmon. "The drought conditions have caused lower flows in the ...

  • The risks of oxygen depletion and enrichment in aquaculture

    Oxygen depletion is a concern on both dry land and in aquatic environments. Dissolved oxygen is present in water and comes from the atmosphere and also photosynthesis by aquatic plants. Dissolved oxygen is necessary to many forms of life including fish, invertebrates, bacteria and plants. Fish and crustaceans obtain oxygen for respiration through their gills, while plant life and phytoplankton ...
