Overall, by pelleting the sample offered the beneficial to isolate Aeromonas spp., Salmonella sp. were observed in catfish, tilapia and water samples. Five species of Aeromonas spp., seven serovars of Salmonella sp., and four species of Listeria sp. However, the sensitivity of the method by pelleting the sample was similar to those of non-pelleting the sample on Aeromonas isolation. The sensitivity of the modified Listeria method was 1 and 0.92 for fish and water samples, respectively. The sensitivity of the modified Salmonella isolation method was 0.53 and 0.73 for fish and water samples, respectively. The modified method (by pelleting the sample in combination with pre-enrichment was the most efficient for Salmonella and Listeria isolation. The modified method was employed by pelleting the samples and followed by either implementing pre-enrichment or without pre-enrichment on the isolation of Salmonella and Listeria spp. A total of 108 samples (32 catfish intestines, 32 tilapia intestines, and 44 water samples were obtained from nine wet markets and eight ponds. in catfish (Clarias gariepinus and tilapia ( Tilapia mossambica obtained from wet markets and ponds in Malaysia by pelleting the sample. IN CATFISH (CLARIAS (Clarias gariepinus AND TILAPIA ( Tilapia mossambica BY PELLETING METHODįull Text Available The aim of this study was to modify the isolation methods of Aeromonas sp., Salmonella spp., and Listeria sp. THE PREVALENCE OF Salmonella sp., Listeria sp. typus, a common crustacean parasite of fish in Southeast Asia, which feeds by sucking blood species, are reported by the first time in the freshwater fish Tilapia from Vellar estuary. Cymothoa indica, a typical Indo-Pacific genus, and A. Gonads recovery in irradiated fishes began from the age of 95 days anatomic sexual differentiation in gonads delayed death of developing oocytes was noted: gonads development in the irradiated fishes of 144 days old was sharply suppressed, some fishes were sterileĬymothoa indica (Isopoda Cymothoidae and Alitropus typus (Isopoda Aegidae on freshwater fish Tilapia mossambica (Cichlidae in Vellar estuary, Southeast coast of Indiaĭirectory of Open Access Journals (Sweden)įull Text Available The study was carried out to establish the extent of double parasitation of two species of isopods Cymothoa indica and Alitropus typus on Tilapia mossambica. Tilapia mossambica Peters larvae of 20 days old after hatching were irradiated with a dose of 350 R. International Nuclear Information System (INIS) ![]() Influence of X-rays on oogenesis in Tilapia mossambica. High concentration of mercury (0.4 ppm) caused considerable. Growth efficiencies were determined on a dry weight basis. Three concentrations of mercury (0.01, 0.04 and 0.4 ppm) were used for experiments on growth efficiency of Tilapia mossambica.
