A releaser pheromone that attracts males in the urine of mature female masu salmon

A releaser pheromone of masu salmon Oncorhynchus masou was investigated using Y‐maze behavioural experiments. During the reproductive season, urine of mature females contains a releaser pheromone which acts as a sex attractant for spermiating mature male parr. The releaser pheromone in mature female...

Zusammenfassung:A releaser pheromone of masu salmon Oncorhynchus masou was investigated using Y‐maze behavioural experiments. During the reproductive season, urine of mature females contains a releaser pheromone which acts as a sex attractant for spermiating mature male parr. The releaser pheromone in mature female urine is one or more low molecular weight substances (less than 10 000) soluble in ether under basic conditions. The attractant was not present in either the coelomic fluid of ovulated females nor in neutral or acidic extracts of female urine which contain free steroids and F‐type prostaglandins, respectively.
