Our goal is to develop and implement new fish collection, holding, transport, and release technology that will significantly improve fish protection at major water diversions in the South Delta region of the Central Valley of California. These research activities are funded by the Tracy Fish Facility Improvement Program (TFFIP) and are primarily performed by Reclamation fishery scientists and engineers at the Denver Technical Service Center and the TFCF, Tracy, California.

Fishes of the Sacramento-San Joaquin River Delta and Adjacent Waters, California: A Guide to Early Life Histories

Johnson C.S. Wang Retires

Johnson C.S. Wang, Ph.D., Volume 44 Special Publication, Fishes of the Sacramento-San Joaquin River Delta and Adjacent Waters, California: A Guide to Early Life Histories

Fishes of the Sacramento-San Joaquin River Delta and Adjacent Waters, California: A Guide to Early Life Histories is the newest publication by Johnson C.S. Wang, Ph.D., that describes the early life stages and histories, taxonomy, and ecology of fishes in and near the Sacramento-San Joaquin Delta.  It has been released as Volume 44 of the Tracy Series and includes information for 48 species representing 22 families.  For each species, information pertaining to spawning, life stage taxonomic characteristics, life history, and ecological status is presented.  The objective of this report is to provide information that will allow a clear identification of all early life stages of each fish species present in the study area.

Johnson Wang retired on February 9, 2011 after 23 years of service as a contract employee to Reclamation at the Tracy Area Office.  Dr. Wang has made many valuable contributions to the taxonomy and identification of fishes of the Sacramento-San Joaquin Delta over his career.  He has trained many Reclamation and Department of Fish and Game biologists, and local university students to identify juvenile and larval fishes.  Dr. Wang has also co-authored several technical reports with Reclamation, Department of Fish and Game, and Department of Water Resources biologists.  Some of his most noteworthy work includes technical reports on the early life stages and life histories of all fish species found in the Sacramento-San Joaquin Delta, and research pertaining to the taxonomic separation of the early life stages of all smelt species (delta smelt, longfin smelt, wakasagi, and surf smelt).  Many of these reports can be found on this website.  Best Wishes to Dr. Wang on his future endeavors!
