Dr. Phaedra Doukakis, Senior Research Scientist with the Institute for Ocean Conservation Science at Stony Brook University and lead author of the study. “We can finally attach numbers to what people have suspected — that current management of Caspian Sea sturgeon fisheries will not prevent further population decline.

Populations of beluga sturgeon have declined by nearly 90 percent in the past several decades due to the high demand for black caviar, inadequate management, and habitat degradation. Researchers advise that the focus must move from relying upon hatchery supplementation to the overfishing of adults. This will not be a popular view, but the American|Kazakhstan team advises that beluga caviar cannot sustain itself under current consumption patterns. Anne
