... Over fishing for menhaden is affecting the water quality and other species of fish in the bay. The government will probably put more restrictions on sport fishermen and say they've done a good job. How does it affect water quality? |

From: http://www.chesbay.org/forageFish/menhaden.asp "Atlantic menhaden are the most important and one of the most abundant fish species in the Chesapeake Bay. During summer months, these fish swim in large schools and their silvery bodies can often be seen near the water's surface. Juveniles primarily feed on zooplankton, but adults are mainly herbivores, but retain the ability to feed on zooplankton. The adults are very adaptable and will feed on several species of phytoplankton, as well as suspended organic plant detritus. Atlantic menhaden are an ecologically critical fish species. They consume and redistribute a significant amount of energy within and between the Chesapeake Bay and other estuaries, and the coastal ocean. This is due, in part, to their tremendous numbers, individual growth rate, filter feeding capacity, and seasonal movements. An adult fish can filter up to a million gallons of water every 180 days. ***A healthy Atlantic menhaden population has the potential to consume up to 25% of the Bay's nitrogen in 1-year.*** Menhaden are also an extremely important prey species for many predatory fish such as striped bass, bluefish, weakfish, and spanish mackerel. Because or their schooling behavior, they are also a favorite target for the common loon, herons, egrets, ospreys, and eagles. -- John H "All decisions are the result of binary thinking." |

snipped John, Have you taken into account that Menhaden are used primarily as a fertilizer? Damn there goes that nitrogen theory! The Chesapeake Bay Foundatoin is nothing more than a wannabee greenpeace org, and has been since its inceptionincepcion. My advice Go to Reedsville, Sign on to a Menhaden processor, and learn about fishing. Heck if nothing else you'll get a free tour on an old Minesweeper. Tell Joe Humphrey or his son, UD sent you. http://community.webtv.net/capuglyda...inUglyDansJack |

Come on down to NO and the wetlands south. Plenty of fish, hunting, decent weather, occasional killer hurricane to thin out the bad bloods. Good eats, too. |

Well since you did, let me respond. You Democratic Borgmen just follow whatever your party bosses tell you, but some of us are smart enough to think for themselves. You might have been able to think for yourself if your mind was not destroyed from excessive drug use. Have you ever figured out if you graduated from Ga. Tech or Univ. of Penn? There is no Kevin Noble in the alumni directory at Ga.Tech Could well be, Fritz. |
