Reproductive bionomics of 2 sublittoral amphipods in a bay of fundy estuary canada

Reproductive bionomics of 2 sublittoral amphipods in a bay of fundy estuary canada

International Journal of Invertebrate Reproduction 2(5): 311-320

The reproductive bionomics of 2 Canadian sublittoral amphipods, Casco bigelowi and Leptocheirus pinguis, are compared in a Bay of Fundy estuary. Casco is semelparous and Leptocheirus iteroparous, although both have a biannual life history. The relatively high reproductive potential of each species, Casco with a reproductive potential of 12.5 and Leptocheirus with 25.5 young/yr, is dictated by a combination of wave-caused sediment washout and predation within the estuary.
