Ichthyoplankton Lab Staff
Ichthyoplankton Identification Experts
The Fisheries Resources Division houses one of the foremost ichthyoplankton ID laboratories in the world. Researchers visit from around the globe to look at the collection, to verify or compare their samples with ours, and to receive training on ichthyoplankton identification from our world class experts. Their job is to sort, identify, measure, and count the ichthyoplankton collected during SWFSC's research surveys. They routinely identify eggs and larvae from the eastern, central, and tropical Pacific.
Data produced in the Ichthyoplankton Laboratory, or "Larval Lab," for short, is critical to FRD's mission to conduct stock assessments and monitor the species and health of the California Current ecosystem. Ichthyoplankton data are key contributions to the stock assessments of Pacific sardine and Pacific mackerel. The data have also been used in recent assessments of Bocaccio and Cowcod rockfishes, and can provide fishery-independent time series information for many other fish species as well as market squid. In addition, the data are used to study distribution and abundance changes of many fish species in relation to climate and ecosystem change in the California Current region as well as the eastern tropical Pacific.
