Efficacy of various chemotherapeutic agents on the growth of Spironucleus vortens, an intestinal parasite of the freshwater angelfish.
Seven chemotherapeutic agents (dimetridazole, metronidazole, pyrimethamine, albendazole, fenbendazole, mebendazole and magnesium sulfate) were examined for growth inhibition on the cultivation of Spironucleus vortens. Dimetridazole and metronidazole were effective in inhibiting the parasite's growth. At concentrations of 1 microgram ml-1 or higher, both dramatically decreased numbers of parasit...
متن کاملPreliminary morphometrics of spleen and kidney macrophage aggregates in clinically normal blue gourami Trichogaster trichopterus and freshwater angelfish Pterophyllum scalare.
Macrophage aggregate (MA) morphometry and pigment composition are believed to be dependent on the species, age, and health status of the fish. The aim of this study was to characterize a "normal" morphometry baseline of spleen and kidney MAs in blue gourami Trichogaster trichopterus and freshwater angelfish Pterophyllum scalare. Three size-classes of clinically normal fish were analyzed. Blue g...
متن کاملThe report of Fibropapilloma in the lips area in a group of freshwater Angelfish (Pterophyllum scalare) in sari city, Iran
Increasing the rate of neoplasms in industrial societies and its wide variety among ornamental and wild fishes in both fresh and salt waters are important. The effect of carcinogenic factors and the role of virus in tumor formation should be considered. In this study 10 3-month-olds Koi and Marble strains of fresh water Angelfish (Pterophyllum scalare), , with cauliflower lesions masses w...
متن کاملThe Role of Body Surface Area in Quantity Discrimination in Angelfish (Pterophyllum scalare)
Although some fish species have been shown to be able to discriminate between two groups (shoals) of conspecifics differing in the number of members, most studies have not controlled for continuous variables that covary with number. Previously, using angelfish (Pterophyllum scalare) we started the systematic analysis of the potential influence of such continuous variables, and found that they p...
متن کاملGrowth and reproductive performance by different feed types in fresh water angelfish (Pterophyllum scalare Schultze, 1823)
It is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. In this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. Twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth...
