Developing a plant-based diet for Cobia Rachycentron canadum

摘要

Aquaculture reached a landmark in 2009, supplying greater than half of the total fish and shellfish ior human consumption (Naylor et al. 2009). With global fisheries in decline and human population increasing, the gap between protein supply and protein demand is widening. Aquaculture must continue to expand to meet these growing needs, and it must do so in a safe, sustainable manner that decreases the world's reliance on harvesting fish for fishmeal while still producing a high quality product. Thereare several difficult hurdles the aquaculture industry now faces if this needed growth is to occur. These include, but are not limited to; the continued heavy reliance upon capture and reduction fisheries to supply fishmeal and fish oil as the major base components for aquatic feeds, build-up of contaminants from these wild caught ingredients in the final products, and public perception that aquaculture in its current state is not sustainable and is a detriment to local ecosystems (Naylor et al. 2009),Tacon and Metian (2009) reported that 36.2 percent of total worldwide catch in 2006 was destined for non-human consumption, meaning the reduction to fishmeal and fish oil for aquaculture diet formulation, the pet food industry, or as bait.
