EEMB Graduate Student Daniel Okamoto Leads a Study That Captures Clues to Sustainability of Fish Populations
Thanks to studies of a fish that gives birth to live young and is not fished commercially, scientists at UC Santa Barbara have discovered that food availability is a critical limiting factor in the health of fish populations.
The scientists were able to attach numbers to this idea, based on 16 years of data. They discovered that the availability of enough food can drive up to a 10-fold increase in the per capita birthrate of fish. And, with adequate food, the young are up to 10 times more likely to survive than those without it.
