the Washington Post reports on a successful effort to convert captive cobia to a vegetarian diet.
The conversion of these carnivorous fish to a completely vegetarian diet is a first, according to the University of Maryland Center for Environmental Science, and a key to breaking a cycle in which the ocean’s stocks of small fish — menhaden, anchovies and sardines — are plundered by industrial fishing partly to provide fish feed to aquaculture, one of the fastest-growing economic sectors in the world.
“It would take the pressure off harvesting the menhaden fishery,” Place said, referring to the bony and oily little fish billed as the most important in the sea. Menhaden, caught off Virginia’s coast, feed a plethora of marine animals, including dolphin, swordfish and birds.
