Kaneohe Bay: Change Over Time

  • Beginning of Sewer Discharges

    Beginning of Sewer Discharges
    Because of sewer discharges, Kane'ohe Bay is being over harvested and degraded by invasive algae. One of the most dangerous of the algae species began to dominate the coral reef since events of sewage discharges that ended in the 1970’s gave nutrients that the algae used to grow rapidly.

    Change Over Time in Kaneohe Bay

  • Kane'ohe Watershed Urbanization

    Because of the watershed urbanization, it has resulted into the problem of sedimentation, which is making the water qualty of Kaneohe Bay worse.
  • Infection of Tilapia

    A disease of saltwater, cage-cultured titapia, Oreochromis mossambicus, caused by the marine monogenean, Neobenedeina melleni Yamaguti, 1963, is described. Up to 400 parasites were found attached to the body surface of individual fish.
  • End of Sewer Discharges

    End of Sewer Discharges
    Although the sewer discharges ended, the algae still continued to grow, which suprised many people. Roght now, projects such as the super suckers are working to decrease and stop algae species such as this.
  • Clean Water Act of 1972

    The Clean Water Act of 1972 is the primary federal law in the United states governing water pollution.
  • Scientific Investigation of Nitrogen Fixation After the Influence of Sewer Discharges

    Nitrogen fixation was investigated in Kaneohe Bay, Oahu, Hawaii, a subtropical eutrophic estuary, by using the acetylene reduction technique on algal samples. No active, planktonic, N2-fixing blue-green algae or bacteria were observed. However, Calothrix and Nostoc capable of fixing N2 were cultured from navigational buoys and dead coral heads.
  • Clean Water Act of 1977

    The revision to the Clean Water Act of 1972. This is where major amendments were enacted.
  • He'eia Ahupua'a Project

    He'eia Ahupua'a Project
    People are now working to reduce sedimentation flowing into Kane'ohe bay from the He‘eia ahupua‘a, a land division extending from mountains to the sea with a historic fishpond at its ocean end. Volunteers are turning 200 acres of wetlands into taro fields, and to catch storm flow and sedimentation, walls are built higher to trap it.
  • Montipora White Syndrome Discovery in Kaneohe Bay

    Montipora White Syndrome Discovery in Kaneohe Bay
    In Kane'ohe Bay, there was a sudden outbreak of a coral disease also known as Montipora White Syndrome known to affect white coral. This had a huge impact on the ecosystem because of the deterioration of the coral reef. The reef houses many of the organisms within the bay, so many organisms didn’t have protection. Scientists propose that the cause of this bacterial syndrome was due to climate change within the seawater, which was created due to the pollution within the water.
  • Alcohol Ban on Kane'ohe Bay

    The state Board of Land and Natural Resources voted today to impose a three-year ban on alcohol at the Kaneohe sandbar during three designated holiday weekends.
  • Super Suckers

    Super Suckers
    One of the practices that are effectively helping protect and preserve the Kane'ohe Bay is one held by a group known as Nature Conservancy and they are sending people with super suckers to clear some of the invasive algae, then placing Hawaiian collectors sea urchins on the excess seaweed to stunt its growth. So far, it has done an effective job.
