Aquaculture accounts for approximately 60 % of Fish Meal and 81 % of fish oil produced globally . While salmon accounts for just 7% of the global aquaculture sector, it consumes 26% of all fish meal and 68% of fish oil used in aquafeeds.
The constant demand for wild fish to feed the aquaculture industry has had negative impacts on targeted species such as Peruvian anchovy stocks.
In Peru, the warm water and low food availability that accompany El Niño conditions are spelling big trouble for the anchovies that make up the largest fishery on Earth. In October 2015, fishermen and scientists argued that a total halt to the second anchoveta (Engraulis ringens) season would be necessary to protect fish stocks from the combined effects of El Niño and overfishing.
We specifically asked Skretting, BioMar and Ridleys for a current breakdown of their fish meal and oil ingredient list, including if their supply chain includes IUCN listed species. We received no up-to-date information from any of the companies. Skretting was the most responsive directing us to their outdated 2016 sustainability report of their supply chain of wild caught fish ingredients which is below.
Of the species listed in the Skretting 2016 sustainability report the IUCN Red List defines their status as:
Peruvian anchoveta: least concern (population trend unknown)
Bullet tuna: least concern (population trend stable)
Mackerel: least concern (population trend stable)
Japanese anchovy: not tested (population trend unknown)
Albacore tuna: near threatened (population decreasing)
Skipjack: least concern (pop trend stable)
Yellowfin tuna: near threatened (population decreasing)
Barracouta: no listing (insufficient data)
Hake: latin name and stated name not matching
Jack mackerel: data insufficient ( population trend unknown)
Javelin fish, aka thorntooth grenadier: not yet assessed (population trend unknown)
Ling: not yet assessed (population trend unknown)
Rattail (generic family listing, not specific species given)
Spiny dogfish: vulnerable. (population decreasing)
Other (non defined)
Given the global nature of wild fish inputs to aquafeed, we are unable to ascertain the 2017-2018 wild fish content of salmon feed at time of publishing this report
