Shrimp are carnivores with a significantly high protein requirement. Fishmeal is the most ideal protein for shrimp, but the scarcity of fish stocks and the high and ever-rising prices of fishmeal have led to the reduction of fishmeal  in formulas. Fishmeal is generally replaced with plant-based protein, or more recently, alternative proteins like microalgae or single-cell protein which can compensate nutritionally but decrease palatability. 
Shrimp are also subject to a lot of variations in environmental factors, which directly impact feed intake. For example, the winter season and low temperatures are often associated with lower feed intake in shrimp ponds. 
As shrimp have complex feeding behaviours with different stages (detection, orientation, choice, ingestion, and rejection of pellets), it is important to ensure that feed will be consumed. A lot of products are used on the market today to enhance feed intake with appetising olfactory compounds, mostly animal hydrolysates, but few products actually look into the inner workings of animal appetite.
