All are aware of the tragic loss of biodiversity that this planet is current going through in various ecosystems. However, a new National Oceanic and Atmospheric Administration (NOAA) report shows that when good policies are in place, natural ecosystems can sustain themselves and thrive. NOAA has released its annual report, stating that a record six fish populations have been rebuilt to healthy levels in 2011. This brings the number of rebuilt US marine fish populations to 27 since the start of the 21st century, showing that great strides have been made to end overfishing thanks to all interested parties.

Can you imagine seas and oceans completely bereft of colourful fish? The possibility may not be all that far-fetched, thanks to rising carbon dioxide (CO2) emissions. By the end of the century, CO2 concentrations in seas will interfere with fish's ability to hear, smell, turn and evade predators, says Phillip Munday, professor at the ARC Centre of Excellence for Coral Reef Studies and the James Cook University.

Shannon Skelton, Environmental Hero with a Fish Story Worth Hearing

The early years were a scary endeavor and squeaky tight financially. Yet, Shannon Skelton knew he could build a better river. With water resources valued for sustaining human life, Skelton had his work cut out for him to champion a new approach to river ecosystem rehabilitation.

Visitors to this city’s burial ground learn more from the dead, particularly about the whale shark and other endangered sea creatures.

The 12-year-old “fish cemetery” of the Bureau of Fisheries and Aquatic Resources (BFAR) has become a field school all year round, even to the curious, according to Westly Rosario, chief of the agency’s National Integrated Fisheries Technology Development Center here.

BATON ROUGE, La. -- A new Louisiana State University study shows the effects of the Deepwater Horizon oil spill on fish living in Louisiana marshes and reveals a problem that could affect the future of the seafood industry.

Oceana turned its press conference yesterday at the National Press Club into a pop quiz: Organizers laid out skinless fillets of halibut next to skinless fillets of fluke, both without labels, and then asked the gathered audience to identify each fish by sight. Oceana then repeated the test for red snapper vs. hake and for farmed vs. wild salmon.

As warming intensifies, scientists warn, the oxygen content of oceans across the planet could be more and more diminished, with serious consequences for the future of fish and other sea life.

I am completely fascinated by this recent news story on CNN.com. On September 10, 2010, an international team of marine biologists discovered a new, never-before-seen species of fish living deep in the Pacific Ocean. The fish, a pure white species of snailfish, was discovered living 4 and ½ miles below the surface of the water; a depth that was previously thought to be devoid of fish. This news is just amazing to me. Isn’t the snailfish a beautiful creature, with its almost angelic appearance? How marvelous that we have the ability to explore the ocean, with its creatures so rare and exotic that they appear to dwell on a different planet.
