A research study was conducted to investigate the number of ovarian eggs and estimate potential egg production of A. leptodactylus. In this study, mean number ovarian eggs 420.41±42.51 with the average total length to 121.93±4.27 mm (n=58). The mean pleopodal eggs were 322.04±29.61 with average total length of 119.14±3.94 mm (n=67). Comparison of the fecundity rate i...

the astacus leptodactylus specimens were collected from four sites of aras reservoir, north-west of iran and examined for the epibionts during 2009. protozoan epibionts from ciliophora (one genus and seven species) and tracheophyta were isolated from the cuticular surface of different body parts of narrow-claw crayfish, a.leptodactylus. seasonal prevalence of infestation was determined in 394 i...

This is the first report of amphibian chytridiomycosis in Asia. We discovered a lethal outbreak in Japan, among 45 exotic frogs from 18 species kept for breeding by a private owner. Of these 45 frogs, 16 died and another 7 were found to be infected by chytrid fungus Batrachochytrium dendrobatidis (Bd) but survived after treatment. Bd was detected in frogs from 9 species (Lepidobatrachus laevis,...
