Generally poor in the U.S., and even worse in many other countries. Regulation of farming, the effects of bottom-trawl nets, and bycatch are the main issues. The highest of any fishery in the world. For every pound of shrimp you buy, an average of seven pounds of other sea life was killed and shoveled overboard. Orange roughy Most orange roughies come from deep waters off New Zealand and Australia.
Depleted populations require many years to recover.
Orange roughies grow very slowly, taking 20 years to reach spawning age. They can live more than 100 years. Many populations were severely overfished when the mild-tasting species' popularity soared, in the 1980s. Poor in New Zealand, where successive populations are being completely fished out. Good in Australia.
