Fecundity, growth, and survival of the angelfish Pterophyllum scalare (Perciformes: Cichlidae) under laboratory conditions.
The freshwater angelfishes (Pterophyllum) are South American cichlids that have become very popular among aquarists, yet scarce information on their culture and aquarium husbandry exists. We studied Pterophyllum scalare to analyze dietary effects on fecundity, growth, and survival of eggs and larvae during 135 days. Three diets were used: A) decapsulated cysts of Artemia, B) commercial dry fish...
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...
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...
