Betaine tend to provides a fun telecommunications that have amino acids inside the boosting the new attractability regarding supply.

Inosine monophosphate (IMP), adenosine diphosphate, guanine monophosphate, and uradine monophosphate (UMP) have been discovered active attractants for the carnivorous fish. Nucleotides including synergistically connect with proteins. Discover proof of variety specificity regarding the effectiveness of different nucleotides and nucleosides. UMP, but not IMP, works well within the eels; whenever you are ATP, however Amplifier, is effective from inside the lobsters.

Betaine and you can glycinebetaine try effective attractants in some marine types, in addition to shrimp, pufferfish, pinfish, pigfish, reddish ocean bream and you can Dover just.
