Reproduction of the Sandbar Shark in the Western North Atlantic Ocean and Gulf of Mexico
The reproductive parameters of 1,194 sandbar sharks Carcharhinus plumbeus (701 females, 493 males) were examined for stock assessment. Size and age at 50% maturity was 151.6 cm FL (12.1 years) for males and 154.9 cm (13.1 years) for females; however, the size and age at which 50% of females were in...
