Native Aquatic Species of the Gila River Basin
in Arizona and New Mexico

Monitoring

Reclamation, in cooperation with the Arizona Game and Fish Department and the Fish and Wildlife Service, has developed and is implementing a baseline study and long-term monitoring program to examine the presence and distribution of non-native fish in the Central Arizona Project aqueducts, SRP canals, Florence-Casa Grande Canal, Gila River below Coolidge Dam, Salt River between Stewart Mountain Dam and Granite Reef Dam, San Pedro River downstream of the US/Mexico border. Reclamation also monitors streams where fish barriers have been constructed.

The New Mexico Department of Game and Fish conducts monitoring of warm water fish communities in the upper Gila River basin of New Mexico and one of its tributaries, the San Francisco River. The Upper Gila River is one of the last major strongholds of spikedace and loachminnow range wide.

Monitoring Techniques

Seining the Canal Electro Fishing Trammel Netting
Seining - a method that catches fish by pulling a net that hangs vertically between two poles with floats on the top and weights on the bottom. Electrofishing - a method that immobilizes fish using electric currents and electric fields so that they can be captured by a dip net. Trammel Netting - a method that entangles fish in a three-layered net, consisting of finely meshed net between two nets of coarse mesh.
