Olaf Jensen, assistant professor at Rutgers University’s Department of Marine and Coastal Sciences, is one member of the scientific community who helps decide how best to manage fish species in New Jersey as a member of the Mid-Atlantic Fishery Management Council’s Scientific and Statistical Committee… Jensen explained the challenges and difficulties in assessing dynamic fish populations. To put his audience of mostly recreational fishermen at ease, he told a funny story about a forester and a scientist having a conversation on numbers. "The forester says he goes out and counts the trees and makes a decision on how many he can cut down while still sustaining the forest. The fisheries manager says, "I do the same thing, except you can’t see the fish and they move."… Determining the amount of the black sea bass biomass and subsequently setting fishing limits has been made more difficult by the biology of that species. Black sea bass are "protogenous hermaphrodites," said Jensen. "They start out as females and change sex," he said.
