Abstract
To support fast-growing and sustainable aquaculture production, the reduction in fishmeal has proven to be a challenge for the development of aquafeeds, because the most important protein source in aquaculture, the fish meal, is a limited resource. A variety of plant proteins have been investigated as possible fish meal replacements for aquaculture diets such as lupins are one of the plant varieties which is non-starch leguminous seeds with high protein sources. Plant protein meals and fishmeal differ in their nutrient composition due to former contains varying levels of antinutritional factors. Antinutritional factors can be reduced during feed extrusion. Typically, lupin seeds have a crude protein (CP) content of between 31 and 42%, which is higher than the content of most other grain legumes. Therefore, we can look the lupin meal as a plant protein source for aquaculture diets.
