Substitutability of Fishmeal and Fish Oil in Diets for Salmon and Trout: A Meta-Analysis

Predicting the Impacts and Socio‐Economic Consequences of Climate Change on Global Marine Ecosystems and Fisheries

“…but ultimately "new feeds" will need to be both technically and economically efficient if they are to be adopted commercially. Substitution in carnivorous aquaculture (e.g., salmon) is nowadays limited (Drakeford and Pascoe, 2008), but the increasing price of fishmeal represents an incentive to innovate on direct replacements (Kristofersson and Anderson, 2006).…”

Preferences for Health and Environmental Attributes of Farmed Salmon Amongst Southern Ontario Salmon Consumers

“…While the production and fish health implications of vegetable oil substitution in salmon feed are active research areas (e.g., Bell et al, 2003;Bell & Waagbø, 2008;Drakeford & Pascoe, 2008), the possibility that market premiums exist for salmon produced using feeds with high vegetable oil content is a new insight.…”

“…Substitution of vegetable oils, which have relatively low levels of POP contamination and n-3 PUFAs, for fish oils in farmed salmon feed has been shown to be technically feasible (Drakeford & Pascoe, 2008) and to significantly reduce the level of PCBs and other POPs in the flesh of farmed fish (Bell & Waagbø, 2008). High levels of n-3 PUFAs can be restored using finishing diets high in fish meal and oil without simultaneously elevating contaminant levels to where they would have been using a traditional feed formulation and feed strategies (Bell et al, 2003;Bell & Waagbø, 2008).…”

Impacts of global environmental change and aquaculture expansion on marine ecosystems

“…Countries importing fishmeal from regions affected by climate variability and change (such as El Niñ o events) are susceptible to fluctuations in fishmeal availability (Deutsch et al, 2007). The limited supply and increasing price of fishmeal has been an incentive to explore alternative protein sources for animal feeds, but to date substitution in carnivorous aquaculture has had limited success (Drakeford and Pascoe, 2008). The patterns in production and use described above have been reflected in the prices of fishmeal in global commodity markets.…”
