About this map
The May to June seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE ofage-0 longfin smelt for each
monitoring station in the SF Bay Study mid-water trawl. The salinity
gradient includes the two months in the season where juveniles are large
enough to be caught by the trawl nets.

About this map
The May to June seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of age-0 longfin smelt for each
monitoring station in the SF Bay Study mid-water trawl. The salinity
gradient includes the two months in the season where juveniles are large
enough to be caught by the trawl nets.

About this map
The May to June seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of age-0 longfin smelt for each
monitoring station in the SF Bay Study mid-water trawl. The salinity
gradient includes the two months in the season where juveniles are large
enough to be caught by the trawl nets.
