Reproduction Preferences Additional InformationThe majority of amphipods are known to brood their young, so that juvenile mobility is probably low but adult mobility is potentially high. Timing on breeding depends on geographic location e.g. May to Oct in one site in France, April to Dec in the other (Dauvin, 1988e), May to Sept on Isle of Man (Hastings, 1981). Some produce two generations per year, others one. First generation live only for four to five months, second generation much longer (Dauvin, 1988e).
