A fish feeding stimulant in one example comprises a host media. The host media comprises an amino acid component with a dominant amino acid. The host media is configured to release the dominant amino acid with a predetermined flux rate into an aqueous environment upon placement of the host media in the aqueous environment. The predetermined flux rate is selected to provide a concentration of the dominant amino acid, in an area surrounding the host media, which exceeds a threshold level for an involuntary feeding response of one or more fish in the area surrounding the host media.
