The most highly prized decapod is probably the true lobster (Homarus species), although overfishing since the early 20th century has greatly diminished the catches of both the North American and the European species. Not only is this bad for the shrimp, the environment in which they're being raised, and the people who are farming them, it could be bad for you as well. 0000181562 00000 n Both prawns and shrimp belong to the decapod order, which simply means they are broth While every effort has been made to follow citation style rules, there may be some discrepancies.
