Postura, desenvolvimento e eclosão dos ovos de Dolops carvalhoi Lemos de Castro (Crustacea, Branchiura) em laboratório, parasita de peixes da Amazônia Central

Laying, development and hatching of eggs of the Dolops carvalhoi Lemos de Castro (Crustacea, Branchiura), reared in the laboratory, parasite from fishes of Central Amazon

Resumo

Dolops carvalhoi Lemos de Castro, 1949 was found infesting fish in a fish culture station located in highway AM-010 Manaus-ltacoatiara in the State of Amazonas. Egg laying of D. carvalhoi was studied. Hatching started after 16 days in a temperature span of 26 to 28ºC. Eggs were laid in clusters on hard substrata and covered by a gelatinous material. The number of eggs was 16 to 392 eggs by laying. In the postembryonic development the larvae were hatched from the egg as juveniles (epimorphic development), very similar to the adult shape.
