  1. Freshwater fish face extinction

    Sweden: Researchers have told an international water conference in Stockholm that 21 per cent of freshwater species in northern Africa are threatened with extinction.

    The International Union for Conservation of Nature study shows that over 1,000 fish, crabs, molluscs, aquatic plants and insects in the region are endangered.

    The IUCN said that agriculture, water abstraction and dams are the biggest threats to these species, urging states to better manage their water resources.

  2. UCA professor urges study of plant’s impact on alligator gar

    By: Associated Press – Texarkana Gazette – Published: 09/07/2010

    CONWAY, Ark.—A study must be conducted to determine the potential impact of a proposed sewage treatment plant in Faulkner County on alligator gar in the area, according to a professor at the University of Central Arkansas who has studied the fish.

    Conway Corp., which operates city utilities in Conway, plans to build the plant about 6 miles upstream of the mouth of the Tupelo Bayou — a site that UCA professor Mark Spitzer says is next to the largest known population of alligator gars in Arkansas.

    “I think we need to have some engineers and scientists make these decisions rather than a corporation,” Spitzer told the Arkansas Democrat-Gazette.

    Spitzer has studied alligator gars and authored the book “Season of the Gar: Adventures in Pursuit of America’s Most Misunderstood Fish.”

    Conway Corp. Chief Executive Officer Richard Arnold said there is already a nearby wastewater treatment facility whose treated waste flows into roughly the same area of the Arkansas River.

    “It doesn’t seem to be impacting the gar,” he said.

    “It’s over 30 years old, and we were going to have to spend millions of dollars to revamp it to meet some different permits,” Arnold said. “The right thing to do is to just go ahead and abandon that one” and build the new one.

    In a letter to Arnold, Spitzer noted that he works with the U.S. Fish and Wildlife Service, the Arkansas Game and Fish Commission and UCA biologists on alligator gar management and said it is not yet known how important the Tupelo Bayou spawning spot is.

    “But what is known is that alligator gar have a very delicate reproductive process that depends on water temperature, water level and time of year,” he added.

    Arnold said the flow from the proposed plant would go directly into the Arkansas River, not into the bayou as is the case with the plant there now.

    Conway Corp. held a public hearing Aug. 27 and intends to forward information on its proposal and any public comments given in the 10 days afterward to the Arkansas Department of Natural Resources for approval, Arnold said.

    Department officials “will be the ones that decide if we need to take a look and study further,” Arnold said.
