Port of Los Angeles Fish Tracking Study

Movement patterns and habitat use of white croaker in Los Angeles Harbor in relation to highly contaminated sediments

White croaker (Genyonemus lineatus) caught in and around Los Angeles Harbor has been shown to contain high concentrations of DDT, PCBs, and other contaminants. The aim of this study is to characterize the movement patterns and degree of site fidelity of white croaker caught and tagged in the Los Angeles Harbor to determine whether the fish leave the harbor and spend a significant amount of time around contaminated sediments. The study is assessing whether these behaviors contribute to the distribution of these contaminants. The white croaker is tracked using acoustic transmitters that actively track the fish for several continuous 24-hour periods. The fish positions are recorded using GPS and the data is analyzed using Geographic Information System (GIS).
