 White Croakers (Genyonemus lineatus)
 Distribution of white croaker in San
Francisco Bay
Within the San Francisco Bay their distribution is primarily confined to the more
marine embayments San Pablo Bay, Central Bay, and South Bay. The various life
stages exhibited different seasonal distribution patterns within the Bay.
The 1+ fish tend to have a more restricted distribution than the YOY and are
found primarily within the Central Bay.
From spring to mid-summer the highest densities of white croaker YOY were
found within San Pablo and South Bays. As the summer progress, the YOY fish
migrate towards the Central Bay. By winter they, along with the smaller 1+ fish,
emigrate out of the Bay.
Annual abundance indices for the
white croakers are generated by the San Francisco Bay Monitoring Program
using otter trawl data.
