3. Use of the term harvest when referring to wild stock exploitation.

We contend that harvest is a misleading term when referring to wild organisms removed from natural systems and suggest that fishery professionals reserve the word for aquaculture products. When referring to wild stock extraction, replacing the word harvest with catch removes the implication of...
