Ranging from Uncle Sam Bank, Baja California to Yaquina Bay, Oregon the queenfish ( Seriphus politus ) is a small member of the croaker family. Ecologically, recreationally, and commercially important, croakers are a common nocturnal, schooling species found largely on nearshore sandy or muddy bottoms. Among impingement samplings at 8 steam powered generating station intakes during a 22 year period queenfish were taken most frequently in 73% of total samples, 62% of total catch, and the highest total biomass at 53%. Despite its abundance and high susceptibility to impingement there is a scarcity of life history information on queenfish. In order to evaluate the species as a whole and gain an understanding of the effects of impingement on its population basic life history parameters must be assessed. To date 230 samples were collected from Southern California during May and June 2006. Individuals ranged from 69 to 206 mm SL and were aged using sagittal otoliths. Using the von Bertalannfy equation 11 age classes were determined where L??= 183.5, k = .2162 and to = -3.607. Life history is discussed in relation to growth rate between sexes and locations as well as weight length relationship, length frequency, mortality and survivorship.
