Thread: Finally! Riffle shrimp larvae!

    Like other shrimp the eggs are "laid" on to the pleopods where they adhere and are carried around by the females until they hatch and the larvae are released into the water column. The larvae are then washed downstream into the estuary or ocean. Some might get washed into backwaters in the river so there is certainly potential for freshwater development. There's been a couple of theses written on them. https://bie.ala.org.au/species/urn:l...746#literature

    Cheers.
    I wasn't able to get hold of those theses but I did find a journal article which cited Smith 1987:

    An interesting quote:
    A. striolata shrimp make longer journeys.
    Adults live in upland streams where, in the wet season, they release
    zoea larvae, which drift downstream, living on their yolk for up to a month (Smith 1987).
    Sorry if this is a silly question, but why do they need to feed when they have a yolk?

    Could the females move to other sites (eg reeds, puddles, burrows etc) when the larvae are about to be released?
