Abstract
This study investigated the properties of fish pellets made with plant-based ingredients intended for rainbow trout (Oncorhynchus mykiss) or other Salmonids. Plant protein from camelina meal (CMM),...

The results showed that a complete replacement of fishmeal with isolated soybean protein (ISP) had negative effects on the growth performance of the fish (Jurij et al, 2012)
The goal of this research was to study the physical quality of fish pellets containing 70% plantbased proteins (CMM, canola meal (CM) and ISP), 10% binders (WGP and Guar gum (GG)) and about 20% fish-based protein for potential rainbow trout feed
Summary
Aquaculture is the farming of fish and other water crustaceans This form of cultivation has gained momentum over the years due to the decrease of wild fish stocks worldwide. Current fish feed mostly contains fish-based meat proteins (fishmeal). In 2016, the amount of the world fish production peaked at 171 million tonnes (mts). Of this amount, 53% or 91 mts was used in aquaculture feed (FAO, 2018a). Vegetable-proteins free of fishmeal have seen growing interests as a replacement for fish meat protein (Adelizi et al, 1998). For the aquaculture industry to grow and thrive, it will be essential to decrease the use of raw fishmeal and increase the use of proteins from plant sources
