Biology

The lamprehuela is a short-lived fish in which, interestingly, females live for a year longer than males, with females living for up to five years, but males living only up to four years (2) (6). Lamprehuela mature shortly after reaching a year old (7), with spawning commencing in late March and ending in July (7). During this time, sexually mature females release hundreds of eggs, (up to 1,400 eggs), into the water (2), in a minimum of two batches (7). Lamprehuela feed on invertebrates, particularly chironomid (non-biting midge) larvae and Ostracoda (small shrimps) (6), as well as detritus and algae (2) (8).
