Francesca Roselli was a RIOS intern and George H Cook scholar in 2015, and graduated from the Marine Science program at Rutgers. Francesca studied population biology of Oyster Toadfish, Opsanus tau, in New Jersey Estuaries. She sampled fish from both the Delaware Bay and Barnegat Bay, examining weight, length, sex, maturity and age of each fish. Comparison between estuaries suggested that the two populations may differ in growth and timing of spawning.
