Endangered Fish in the Colorado River Basin
The Colorado River Basin is home to many different species of fish. Of the different species, four of them are threatened and are considered endangered species. ... There are many factors that contribute to the decrease in numbers of these particular fish. There needs to be efforts made to preserve these fish so the whole ecosystem is not disrupted.
The river basin as well as being as home to these rare fish provides water to millions of people. ... If nothing changes and these four fish continue towards extinction, the biodiversity of the entire system would lessen and the conditions would not be the same ever again.
There are fourteen native fish species in the Colorado River Basin of which four are endangered. ... They have only been able to trace adult fish, and once those are gone they fear that will be the last of the Razorback Sucker. Another fish that is in danger is the Colorado Squawfish; it is the largest member of the minnow family in the United States. ... This fish used to be harvested for food and it migrates in excess of two hundred miles for spawning. The other two endangered fish are different kinds of Chubs. ... The last fish is the Bony tail Chub. It is the rarest of all these species of fish and can reach up to two feet in length. ... Of these fourteen native fish, we have the four species that are endangered, and they have to compete with forty-one species of non-native fish for space and food. ... Another factor that has affected these fish is pollution. ... There have been huge changes in habitat both upstream and downstream of the dams, not only for these fish, but also for other aquatic life forms. The dams have stopped the runoff from cleaning the riverbeds, therefore leaving no spawning sites for the fish.
