Alewives are in serious trouble in some areas

Casey, alewives are not women who brew ale in the bathtub, but thanks for asking. Please pass this on to your twin brother Clyde and your cousin Clementine.
Alewives are actually members of the herring family, are relatively small but very abundant. They swim in huge schools, feeding on plankton and small animals and plants. The adult common herring, Clupea harengus, found in temperate and cold waters of the North Atlantic, is about a foot (30 cm) long with silvery sides and blue back. It lays up to 30,000 eggs, which sink to the sea bottom and develop there, and the young mature in three years. Other species lay their eggs in seaweed in shallow waters, and still others, the anadromous types, spawn in large rivers. Best known of these is the American shad, Alosa sapidissima. They are found along the Atlantic coast from Nova Scotia to South Carolina and landlocked in Lake Ontario and the Finger Lakes of New York. The menhaden is an extremely abundant species of the Atlantic coast of North America. It was used by Native Americans to fertilize their cornfields (its name is the Narraganset word for "fertilizing"); a billion pounds of menhaden per year is converted into oil and fish meal. The skipjack, a streamlined, steel-blue herring 15 inches long, is found in the Mississippi River and the Gulf of Mexico. Its name, describes any fish with a habit of leaping clear of the water.
However, the alewives are in serious trouble in some areas.
This silvery fish has been washing ashore once more on Lake Michigan beaches.
While not as many of the little fish are dying as in the 1960s, it's one of the larger kills in recent years. Millions of stinking alewives littered the shoreline for miles last fall, chasing away picnickers, beachcombers and swimmers. They are also washing up on the shores of Lake Champlain in large numbers. State fishery biologists from the Vermont Fish & Wildlife Department say it's an example of the kind of problems a non-native invasive species can cause. First documented in Lake Champlain in 2005, alewives have since been found throughout most of the lake. Large numbers of young alewives were first observed in the Inland Sea last year.
Vermont Fish & Wildlife biologists responded to numerous calls from concerned anglers reporting dead fish washing up on shores of the Inland Sea during this January's thaw.
Fisheries Biologist Bernie Pientka and Fish Health Biologist Tom Jones investigated and found tens of thousands of dead and dying alewives, most about three inches long and one year old. Adult alewives as large as eight inches were also documented. Results of testing showed that these alewives were negative for viral hemorrhagic septicemia (VHS), a disease that is killing fish in the Great Lakes.
"This type of winter kill of alewives wasn't unexpected," said Shawn Good, chair of Fish & Wildlife's Aquatic Nuisance Species Team. "Alewives are an exotic fish species native to the Atlantic Ocean, and they are not well adapted to winters in freshwater lakes such as Lake Champlain. Alewives are easily killed by rapid changes in water temperature that occur in the winter."
The story did not end in January. Throughout the winter additional reports of dead and dying fish were received from anglers as far south as Westport, N.Y. and Basin Harbor, VT. In many cases, anglers were reporting that dying alewives were observed swimming up into recently drilled holes in the ice.
Dead fish tend to stay preserved for long periods of time in cold water. As spring temperatures melt the ice, the dead alewives trapped under the ice float to the surface and wash up on shore. Lakefront property owners in certain areas of Lake Champlain are likely to see large numbers of dead alewives on their shorelines. Alewives can take over a lake and reduce the smelt population which is the favorite forage of landlocked salmon. However, with the reduction of alewives, the smelt population increases and the salmon fishery improves. Bass and alewives will feed off of each other but the bass will eat more of the alewives. These fish are a source of income to coastal communities and many fresh water sportfish utilize young alewives at mealtime.
The alewife is used as bait for many fishes as well as for chum. Many are canned, salted or smoked, although the flesh is bony and of poor quality. The roe is excellent.
With the growing concern of fish diseases like VHS, the Maine, New Hampshire and Vermont Fish & Wildlife Department are very interested in fish kills statewide and what people are observing. Accurate disease testing requires recently dead or dying fish, so if you observe dying fish on any of waters, be sure to contact your local warden.
Avoiding the sharp eyes of game animals is a high priority for sportsmen. Using a good camouflage pattern is important, but if you move at the wrong time, you run the risk of being detected. A portable blind helps solve the problem by allowing the hunter to remain concealed while hiding excess movements.
While some blinds can be bulky and difficult to set up, Hunter's Specialties® Collapsible "Super Light" Portable Ground Blind makes transportation easy and hassle free. It folds into a handy package that allows hunters to carry it in their pocket or hunting vest. When you get ready to set it up, simply unsnap the elastic strap, unfold the legs and place them in the ground. Set up, the blind measures 12 feet long by 27 inches high.
A spun-bonded polyester material with die cuts for a 3-D effect makes up the camouflage. Built to last through years of use, the Collapsible "Super Light" Portable Ground Blind is available in Realtree® APG"¢, Realtree® AP"¢ and Advantage® Max-1 HD"¢ camo patterns.
