Although Octopus are wide-ranging and have short lifespans, some populations are declining due to heavy fishing pressure. Most Octopuses are caught using bottom trawls, causing habitat damage and bycatch of unwanted wildlife.
Management and monitoring of Octopus fisheries are weak in many countries.
In almost any situation Argentine or Longfin Squid can be a great substitute for Octopus. Squid however does not need nearly as much time to cook as Octopus. Squid does remarkably well with a quick grill or a minute under the broiler. It pairs well with the Mediterranean flavors often combined with octopus.
