At a glance

Almaco jack farmed in Mexico in marine net pens is rated yellow. Habitat impacts are minor, and the scale of production is currently low. In addition, the available information suggests compliance with relevant regulations. The industry hasn't reported the use of antibiotics, but chemicals are regularly used to control parasites, though the substances are a low risk to the environment. The feed's marine-based ingredients are sourced from sustainable fisheries, but it takes 1.48 tons of wild fish to produce one ton of almaco jack. Also, the open design of net pens means there's a risk of escape and transferring disease to wild species.

FARMING METHOD

Marine net pen

Marine net pens are structures that hold farmed fish in open water as they grow. They're enclosed on the bottom and sides with wooden, mesh or net screens, which allow water to flow freely through them. Species such as amberjack and salmon are farmed in marine net pens.
