As the world ages, and humans develop and change the natural environment,
The problem is that an old fishery in Pennsylvania, the Huntsdale
State Fish Hatchery, has been neglected to be repaired.
Neglecting these repairs has led
to numerous problems concerning the fish hatchery.
Due to the lack of repairs, excess
amounts of fish feces have been polluting local waterways of Pennsylvania, and
destroying the environment.
According to Gvozdas (2003) the fish feces coming out of
the fish hatchery have decreased the oxygen supply in the streams and have killed plant
life and native fish.
In response to this problem, the fishery began stocking less fish into
waterways, which impacted recreational fishing and decreased revenue from fishing
Without good fish to catch, there is no reason for fishermen to pay the high
prices for a fishing license.
During the period of reduced fish stock, the Pennsylvania
Fish and Boat Commission made $16.9 million dollars, losing $700,000 from the
previous year (Gvozdas, 2003).
Not only does the old, damaged equipment present a problem for the environment
and the economy, it also presents health risks for the fish being raised within the fish
The old equipment clearly has issues dealing with water quality, which not
only impacts the health of native fish, but the fish in the hatchery itself.
water quality can easily lead to disease, and the dying fish are only a waste of scare funds
and resources that the fish hatchery has.
Overall we can see that the Huntsdale State Fish
Hatchery has problems concerning finances, the environment, and its own fish health.
The Huntsdale State Fish Hatchery is
located in Cumberland County, Pennsylvania.
On average this fish hatchery produces 461,280
pounds of trout per year, making them the
highest producer of trout in Pennsylvania
(Commonwealth of Pennsylvania, 2011).
Huntsdale raises fish like: striped bass, channel
catfish, tiger muskellunge, brook trout, brown
trout, golden rainbow trout, and rainbow trout.
This fish hatchery uses the traditional rectangular
tanks or raceways to raise their fish.
raceways are typically the type of tanks used to raise these
Raceways are made of concrete and have screens
over them to protect fish from predators (if outside) and to
keep the fish from jumping out (NRCS, 2001). These tanks
are also known as flow through tanks.
This means that water from a source is passing
from tank to tank from one end to the other.
Each time the water moves to a new tank
oxygen is added.
This means that there is always more oxygen at the top of the tank
where the new water is coming in.
The highly oxygenated water is better for fish, so the
fish will tend to mass themselves at the top of the tank, where the better water is, and the
rest of the runway (lower third) goes unused.
Also, because the water is flowing from
tank to tank, the spread of disease cannot be controlled between tanks, which is a major
