Still Raising after all these Years
DEC's Rome Fish Hatchery
By Joelle Ernst and Bob Lewthwaite
Staring at the water's surface, it looks like the wind has picked up even though it's a calm, sunny day. But it's not wind that's causing ripples in the water of the long rectangular ponds at the Rome Fish Hatchery, it's thousands of small trout-eating and growing in preparation to make their debut in streams and lakes across New York.
I recently visited the hatchery to get ideas for designing content for the newly built Visitor Center. Having been to many hatcheries during the course of my work, I knew I would enjoy the visit because there are so many interesting things to see. What I wasn't expecting, however, was to be captivated by the rich history of the place. You see, ever since I can remember, math and science have always been my favorite subjects. History on the other hand, left much to be desired

Prior to being a hatchery, the property was the site of the first cheese factory in America! Set up in 1851 by a local dairy farmer named Jesse Williams, this innovative factory paved the way for large-scale commercial cheese production in the U.S. What is now the Rome Hatchery's crystal clear, cold spring water supply was used then to cool milk. Years later, the property housed a grist mill where the springs powered a water wheel. The horses on the farm were used to pull boats on the nearby Black River Canal that ran between Rome and Lyons Falls.
In 1915, the first fish hatchery was established on the property by Harry Ackley. A pioneer in trout production, Ackley successfully raised trout to large sizes for stocking in public waters.
Following the closure of the canal around 1920, a couple of additional small fish farms were built on the grist mill property. One was operated by Dr. George Reid, the other by the Rome Fish and Game Club, which built ponds and troughs for raising fish.In 1930, the Fish and Game Club sold its parcel of land for $1.00 to the State of New York to develop a fish hatchery. Local volunteers donated their time to help build more ponds to enlarge the facility and in 1932, the state purchased the Reid holdings, giving them exclusive rights to all springs on the property. This was the beginning of today's Rome Fish Hatchery.
Running a hatchery presents many challenges. For instance, the cold water springs that feed the Rome Hatchery have excellent water quality for growing trout, but water volume can greatly fluctuate over the year. So, when the Black River Canal closed, an abandoned pipeline from nearby Lake Delta was incorporated into the hatchery water supply, greatly increasing the number of fish that could be raised.
Today's staff do the same types of work
that Ackley's staff did-like monitoring
fishe's health and keeping troughs and
ponds clean (above)-the hatchery's
water source is a bit different. Rome
Hatchery now gets some of its water
from nearby Lake Delta (see aerial
photo at top of article).
Since then, the Rome Fish Hatchery has undergone many other large-scale expansions and improvements. In 1954, earthen ponds were converted to raceways-long, rectangular rearing units like the ones I was observing-to improve water flow and quality. A one-mile long polyethylene pipeline from Lake Delta replaced the leaking, old wood staved pipe in the 1970s. In the 1980s, all the piping from the springs was replaced. Clarification ponds, which remove fish waste, were constructed in 1990. Pole barn enclosures built over the East Ponds in 2008 prevent birds from preying on the fish. The old hatchery, built in 1932, was demolished in fall 2009 and replaced with a more energy-efficient building in 2011. The newly built hatchery boasts everything from an early rearing area, or "hatch house" as the hatchery staff call it, to a visitor center.
Having a functional, efficient hatchery is extremely important when you're talking about millions of fish being produced each year. Yes, you read right
Running a fish hatchery is a complicated business. A coldwater hatchery, Rome raises brown trout and brook trout. Unlike some other DEC hatcheries which maintain their own sources of eggs, each fall Rome receives its fish eggs from other DEC fish hatcheries as well as other sources. The eggs are then incubated in special screen baskets in the hatch house. About 50 days after spawning, the eggs hatch. The emergents, called sac fry, are born with a yoke sac that nourishes them for ten to fourteen days. After the yoke sac is absorbed, the fry are transferred to rearing units/troughs (also in the hatch house) and hand fed a dry starter diet six to eight times a day. As the fish grow, the amount of space they need increases, so they're moved outside into the raceways. Some fish are fed using a specially equipped truck, or via demand feeders where fish bump into a rod protruding into the water to release food. Troughs and raceways are cleaned by staff each day to remove fish waste. Larger fingerling and yearling fish are moved to large concrete ponds. Staff also monitor the fishes' health daily, and test them regularly to make sure they are growing properly and staying healthy.

All of the brown trout and most of the brook trout raised at Rome Hatchery are domesticated-bred for disease resistance and adapted to life in a hatchery. But some wild, "heritage strain" brook trout are also raised here. New York's state fish, the brook trout, are native to the state and these heritage strains have been shown to live longer and grow larger than domesticated strains. Heritage populations are important to the adaptive ability and long-term survival of the species, and represent an irreplaceable part of the brook trout resource in New York State. The most common strains raised in DEC's hatchery system include Little Tupper, Windfall and Horn Lake. Rome Fish Hatchery raises "Little Tuppers," as well as a strain that is a cross between a domestic brook trout and a wild Temiscamie (Canadian-strain) brook trout. This hybrid has a better survival rate in some of the more acidic waters of the Adirondacks. Because the number of heritage strain brook trout produced each year is determined mainly by the number of eggs taken from wild fish, most Adirondack waters are stocked with Temiscamie hybrids.
Rome Fish Hatchery is responsible for stocking more than 350 public waters in 11 counties of the state. They stock as far north as Lake Champlain in Essex County and as far south as Otselic River in Chenango County. Many remote waters in the Adirondacks cannot be reached by truck so they are stocked by air using helicopters and pontoon/float planes.

So, if you are looking for something to do with your family this summer, consider visiting the Rome Fish Hatchery, or one of DEC's other 11 hatcheries scattered across the state. With so much to do and see, everyone is sure to have fun!
