Native Fish Projects

RCRCD conducts the Santa Ana Sucker Conservation and Research Program, in cooperation with the US Fish & Wildlife Service (USFWS) and the California Department of Fish and Wildlife (CDFW). These studies compare the Sucker’s tolerance to different levels of water pollution, life history and longevity, both in captivity and in the wild. The Santa Ana Sucker was listed as a threatened species in 2000 and numbers in the river continue to fluctuate greatly due to a number of factors such as drought, infrastructure projects, and sedimentation from fires and from other environmental and man-made impacts. Some projects include:

·         Santa Ana Speckled Dace Breeding and Reintroductions

·         Arroyo Chub Breeding and Population Augmentation

·         Santa Ana Sucker Reproduction and Life History

·         Santa Ana Sucker Endocrine Disrupter Study

·         Rainbow Trout Egg Elasticity
