Length‐measurement conversions and seasonal mass–length relationships (MLR) for Pacific herring Clupea pallasii , northern anchovy Engraulis mordax , Pacific sardine Sardinops sagax , Pacific mackerel Scomber japonicus and jack mackerel Trachurus symmetricus in the California Current are presented. The conversions between total ( L T ), fork ( L F ,) and standard lengths ( L S ) should facilitate comparisons of data across dis...

Because of this relatively long duration and squid’s pelagic life history, egg cases provide a practical life stage to survey. During 2001–2002, squid egg beds in Monterey Bay, Carmel Bay, and around the California Channel Islands w...
