Many American fish species were considered dead over a long time. Many of them were driven to the limits by pollution, overfishing, dam construction, and habitat loss. In other instances, decades went by without even a glimpse of them and it was even announced that they were extinct or lost. Then, in a sudden, there were small population survivals. These rediscoveries brought conservationists hope and demonstrated that nature is stronger than one may believe.
Alabama Sturgeon

The Alabama sturgeon has been discovered again to the shock of the scientists after being presumed to be extinct following extensive pollution and alterations to the rivers. In Alabama River, a few people were discovered. The fact that it returned emphasized the vulnerability of freshwater ecosystems. The remaining habitat of the species is now being conserved.
Smoky Madtom

This small catfish went extinct but in the era of 1980s it reappeared.Its resurgence indicated that little fish could live in the shadow. Protection of clean water assisted in providing this species with another opportunity.
Scioto Madtom

The Scioto madtom was believed to have disappeared in years of fruitless surveys. Small populations were later discovered in the state of Ohio. The habitat restoration was vital in its survival. Its restoration rekindled the conservation of streams.
Modoc Sucker

The Modoc sucker was thought to have been extinct in the areas of california but somehow got seen again.It was almost killed by agricultural runoffs. Care programs assisted in stabilizing its population. It became a representation of effective protection of freshwater.
Lost River Sucker

Damming and water diversion has long been thought to make this fish functionally extinct. Small populations were subsequently substantiated. The restoration of wetlands increased the chance of survival. Its narrative depicts how humans can destroy as well as restore the ecosystem.
Shortnose Sturgeon

This prehistoric fish appeared again which was declared extinct at a time.It made its numbers gradually recover with the help of protection laws.The conservation of rivers is necessary.
Atlantic Sturgeon

The Atlantic sturgeon had been written off in a number of waterways in the United States, and it came back to the surprise of scientists. The fishing prohibition and the purer rivers assisted in recovery. It is still threatened yet it lives. Its existence implies the amelioration of water quality.
Colorado Pikeminnow

This large native fish managed to survive, which was thought to be almost extinct in some areas of its range. The conservation hatcheries were used to reestablish populations. The most important thing was river flow management. Its reentry brought western rivers back to the level.
Razorback Sucker

This fish that has a strange appearance was thought to have been lost in the wild over years. That was changed through captive breeding and reintroduction. It is now surviving within controlled environments. Long-term conservation is demonstrated by its successful return.
Devils Hole Pupfish

This small fish survived, after it was thought to be going to extinction because of declining water levels. Its habitat was saved through the intensive protection. It still survived despite being threatened. It is one of the few success stories of fish in America.
