The Fishing Industry in Pennsylvania: Part Two



Shad Fishing (con't)
In the early 1800s, the construction of the three dams hurt the shad fishing. The Shawmont and Reading Dams on the Schuylkill River were built to make the river more travelable by boat. The Fairmount Dam also on the Schuylkill made a reservoir for a water works company that provided water for Philadelphia.

the shad from spawning in the Schuylkill River, the best place to fish for shad at that time. Likewise, the building of the canal system during the same period inhibited the shad from coming up the Susquehanna River.
To provide a place for the shad to go upstream beside the dams, the government tried constructing fishways. Fishways provided water-filled steps that the fish could leap. Unfortunately, the fishways did not help the shad because they had already quit migrating up the Schuylkill. For a reason, experts point to the pollution caused by a gas works built on the lower part of the Schuylkill in 1830.
The government also attempted raising shad in hatcheries and putting them into streams but gave up this project in the 1930s.
In 1890, commercial fishermen harvested sixteen million pounds of shad from Delaware River.  The 1905 figure dropped to three million. The last time a million pounds were caught in the Delaware was in 1916. The Delaware River had a bit longer success with shad fishing, but overfishing, pollution, and other environmental factors decreased the number of fish. Thus, the Pennsylvania shad industry couldn’t survive and closed down in the middle of the 1900s. Many fishermen went to work in the World War II shipyards.
A viable fishing business resurfaced in the Delaware River after the water from two hurricanes in August 1955 removed the pollution barrier at Philadelphia. Fish are again able to migrate up this river, and the American shad have come back as a marketable fish. Shad are being stocked from fish hatcheries and now use the fish ladders to get past dams.
Buying fresh fish at an outdoor market is again popular in Philadelphia especially at the Italian Market, the oldest and largest outdoor market in the United States and at the Reading Terminal.
