Rearing of Embryos and Larvae of the Australian Lungfish, Neoceratodus forsteri, under Laboratory Conditions

Larval lungfish were reared under laboratory conditions to stage 55 (52 mm). Suitable foods were daphnia, chironomid larvae and tubifex for all stages, and hen's egg yolk with or without vegetable juices for older stages. Increase in size of larvae was not affected by available space under the conditions of culturing described. Temperatures within the range of 18-22 C gave the same growth rate but 10 or 30 C were lethal to cleaving eggs. The conditions described permit rearing of lungfish for detailed embryological and histological studies.
