Attractants effects on digestive function

The aims of the Attractants on Digestive Function research project is to investigate the mechanisms by which larval fish sense prey in the water and the physiological responses elicited by prey detection. Much like we experience hunger pains upon smelling something good to eat, larval fish have a distinct series of reactions in response to the presence of something attractive to them. Understanding how this attraction works and how it primes the larval digestive tract is key to the development of ideal feeds for altricial larvae.
