This study aimed to identify the cause of sustained mortality in freshwater angelfish (Pterophyllum scalare Schultze, 1823) kept at an ornamental fish production facility Türkiye. Parasitological, bacteriological and histopathological examination were performed on moribund hybrid individuals. The had haemorrhaged eyes, darkened skin, scale loss, ascites false faeces. A pale liver, splenomegaly ...

The present study aimed to evaluate the growth performance, batch uniformity, and survival rate of Amazonian ornamental fish Heros severus Pterophyllum scalare during post-larvae growing stage, fed with diets containing levels Euterpe oleraceae essential oil (EOO) 30 days. In first experiment, 160 H. were distributed in 16 aquariums (1 L), second, 200 P. randomly 20 L). experiments carried out ...

parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. in this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: goldfish (carassius auratus), guppy (poecilia reticulate), angelfish (pterophyllum scalare), discus (symphsodon discus) and sailfin mollies (poecilia latipinna) was obtained from a l...

Melanophores of the angelfish, Pterophyllum scalare, were studied in an attempt to demonstrate the existence of actin in these cells although microfilaments had previously not been found. By use of a variety of procedures, including immunofluorescence microscopy of intact and detergent-extracted cells, transmission electron microscopy, high voltage electron microscopy of whole-mount preparation...
