Bullheads: The Humble Hornpouts

bullhead by adelaide tyrolConsider for a second a fish that can live in turbid, low-oxygen water. Can breathe through its skin. Eats almost anything. Has a wickedly effective defense mechanism. And is a really focused parent. Plus, it’s good to eat.

We’re talking about the humble hornpout. Or “horned pout,” if you prefer. Or “mud cat.” Taxonomically, Ameiurus nebulosus. The brown bullhead. » Continue Reading.

Fish Scales and American Shad

american shad It’s tempting to simply view fish scales as armor, but there’s more to them than that. They provide camouflage; they also play a role in locomotion. For scientists working on the recovery of American Shad in the Connecticut River, scales provide a record of a fish’s life history and a way to measure the success of restoration efforts.

American shad is our largest river herring. The males, called bucks, run up to six pounds. The females, or row shad, up to four. Like their cousins alewife and blue-backed herring, shad are anadromous, spending most of the year in the ocean, then running up fresh water rivers like the Connecticut in spring to spawn. » Continue Reading.

Beneath The Ice: The Quiet Parlor of the Fishes

ice skating When I’m skiing or skating across a pond, I observe the shoreline, surrounding hills, islands, maybe a woodpecker or blue jay winging its way to the opposite shore. I look up at the sky, the clouds, swirling snowflakes. But there is a world beneath my feet that I don’t see, in what Henry David Thoreau called “the quiet parlor of the fishes.”

Beneath a layer of ice up to three feet thick, fish, reptiles, amphibians, and tiny invertebrates are going about their winter business. For most of these creatures, this means slowing their metabolism down to survive with reduced light and oxygen. They move less, eat less, and breathe more slowly than in warmer months. » Continue Reading.

More Adirondack Lake Trout Monitoring Needed

spawning lake trout Lake Trout are designated species of Greatest Conservation Need in NY, based on the reduction of cold, well oxygenated waters in lakes due to climate change.

Lake Trout, Salvelinus namaycush are one of two native salmonines to the interior Adirondacks, Brook Trout, S. fontinalis being the other.

However, unlike Brook Trout, which can be found from small headwater streams to deeper lakes, Lake Trout reside in the hypolimnion (bottom) of lakes during the majority of the year, where water temperatures are most suitable. The depth of the hypolimnion depends on many factors, including latitude, size of the lake, and the height of surrounding land that offers protection from the wind.  » Continue Reading.

Equipment Failure At Adirondack Hatchery Hits Salmon Stocks

adirondack fish hatcheryA severe storm Friday, May 4, cut power to the Adirondack Fish Hatchery at Lake Clear, east of Saranac Lake, killing most of the salmon stock.

Power lines to the hatchery were downed during the storm according to DEC, causing the facility’s backup generator to activate. When power was restored from the grid, it caused the backup generator to go off-line, and a transfer switch failed. That failure prevented the flow of well water into the raceways, depriving the salmon of oxygenated water.

The New York State Conservation Council estimates more than 85% of the salmon that remained in the raceways following the spring stocking operations were lost – or more than 250,000 fish. » Continue Reading.

New State Records for Walleye, Black Crappie

record walleyeTwo new state fishing records were set over the course of one weekend in New York recently.

Brian Hartman of Alexandria Bay eclipsed the 2009 state record walleye by more than 1.5 pounds when he caught an 18-pound-2-ounce walleye from the St. Lawrence River on May 5 using a swimbait.

On May 6, William Wightman of South Dayton used a black marabou jig to reel in a 4-pound-1-ounce crappie from Lake Flavia in Cattaraugus County, exceeding the 1998 state record by five ounces. » Continue Reading.

Adirondack Fish Hatchery Springtime Visits

Though trout and salmon season may have opened on April 1st, the fluctuating temperatures have not made anyone in my family interested in early season angling. Though fishing may not be on my children’s agenda, a visit to the Adirondack Hatchery is always a springtime tradition. Each of the 12 DEC operated fish hatcheries raise specific species of fish, with the Lake Clear hatchery’s specialty being landlocked Atlantic salmon. » Continue Reading.

Invasive Alewife Spreading In Champlain Basin

alewife

Recently, an avid angler noticed an odd fish in his bait bucket and reported it to the Vermont Fish and Wildlife Department.

The species was identified as a mosquito fish (Gambusia affinis) and the Department took quick action to locate the baitfish dealer, dispose of the non-native fish, and ensure that no more shipments from the baitfish supplier were allowed to enter the State. » Continue Reading.

Environmental DNA: Frontiers of Adirondack Science

Filtering Stream WaterConserving our native fish is a major goal of the Ausable River Association (AsRA). We know the Ausable River watershed, particularly the high elevation tributaries to the East Branch, is one of the most likely places to retain Brook Trout under future climate warming scenarios across their native range. We also know that much of that habitat is fragmented by undersized culverts that serve as barriers to fish passage. Finally, we know that introduced non-native species, such as Brown Trout and Rainbow Trout, threaten our native fish populations. These facts are well documented in the scientific literature and summarized in reports produced by the Eastern Brook Trout Joint Venture.

When developing conservation strategies to protect our native fish, one of the first things we need to understand is where fish are. Surprisingly, we know very little about where Brook Trout and other native fish are found in the Ausable River watershed. We have a broad sense of their distribution, but when we walk up to a particular reach of a small tributary we are often making “best guesses.” Before doing stream or habitat restoration work, we take the time, with our partners at the U.S. Fish and Wildlife Service, to survey the fish population. » Continue Reading.

DEC: Endangered Adirondack Round Whitefish Recovering

Round WhitefishThe New York State Department of Environmental Conservation (DEC) has announced that Round Whitefish may soon be taken off New York’s list of endangered species and reclassified as threatened.

Fisheries biologists recently netted 15 Round Whitefish in Bug Lake of Hamilton County near Inlet. Six of these fish were second generation after stocking.

This will be the third water with offspring found after stocking. The first two include Trout Pond of St. Lawrence County and Evergreen Lake of Herkimer County.  DEC chose Bug Lake for stocking because it is a cold and clean lake which has provided a high-quality fishery for brook trout and lake trout. » Continue Reading.

Adirondack Fisheries: The Redbelly Dace

Summer is the season for being on the water in the Adirondacks, and a canoe or kayak is the perfect way to explore the many ponds, slow-moving rivers and marshes that exist throughout the Park. While these shallow, muddy-bottomed settings may not be great for swimming, the rusty-tan water occasionally covered with patches of floating leaves and strands of submerged vegetation does teem with life. Among the residents of these quiet, weedy waterways is the redbelly dace (Phoxinus eos), a common and widespread member of the minnow family of fish. » Continue Reading.

Non-Native Jellyfish Found In Newcomb ‘Heritage Lake’

View of Wolf Lake during summer 2016A SUNY College of Environmental Science and Forestry undergraduate received the Hudson River Foundation’s Polgar Fellowship this summer to conduct water sampling in Wolf Lake on SUNY-ESF’s Huntington Wildlife Forest (HWF) under my guidance.

Sampling will be conducted to determine if water quality changes observed over the past few summers in Wolf Lake might be due to a relatively unknown but widespread organism, the freshwater jellyfish Craspedacusta sowerbii. » Continue Reading.

Lake Sturgeon Recovery Efforts Show Signs of Success

lake sturgeonThe New York State Department of Environmental Conservation (DEC) is asking anglers to avoid spawning lake sturgeon in New York’s waters.  Lake sturgeon are New York’s largest freshwater fish and can grow up to seven feet long and weigh more than 200 pounds.  They are listed as a threatened species in New York

Typically during this time of year, DEC receives multiple reports of lake sturgeon (Acipenser fulvescens) caught by anglers fishing for walleye and other species. » Continue Reading.
