I feromoni dei pesci - Il giornale del mare
Skip to content I feromoni sono sostanze chimiche rilasciate da un organismo che influenzano il comportamento o la fisiologia di un altro organismo della stessa specie. Anche se più studiate negli insetti e in alcuni mammiferi, le feromoni sono presenti anche nei pesci e possono svolgere vari ruoli.
Un esempio di queste funzioni è l’attrazione sessuale . Alcuni pesci maschi rilasciano feromoni per attrarre le femmine durante la stagione riproduttiva. Le femmine, a loro volta, possono rilasciare feromoni per segnalare la loro disponibilità a riprodursi. Queste feromoni possono anche aiutare a sincronizzare l’ovulazione tra le femmine, assicurando che ci sia la massima possibilità di fecondazione.
Inoltre, i feromoni dei pesci possono essere utilizzati per segnalare la presenza di predatori. Alcune specie rilasciano una sostanza chimica quando sono attaccate da un predatore. Questi “feromoni di allarme” avvisano gli altri pesci nelle vicinanze del pericolo.
I feromoni possono anche essere utilizzate per aiutare i pesci a ritrovare il loro luogo di nascita quando è il momento di riprodursi, un comportamento noto in alcune specie di salmoni.
I feromoni svolgono un ruolo cruciale nella comunicazione e nella sopravvivenza dei pesci, influenzando una varietà di comportamenti, dalla riproduzione alla fuga dai predatori.
