Although infections caused by megalocytiviruses have been reported from a wide range of finfish species for several decades, molecular characterisation of the viruses involved has been undertaken only on more recent cases. Sequence analysis of the major capsid protein and adenosine triphosphatase genes is reported here from formalin-fixed, paraffin-embedded material from 2 archival ornamental f...
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...
HighlightThe growth of angelfish which supplemented D. magna enriched ascorbic acid was identified and analyzedThe survival rate after challenge test using A. hydrophylla composition in analysed iodometry titration that has been added analyzedAbstractAngelfish (Pterophyllum scalare) is a tropical ornamental fish freshwater with considerable potential the global market promising cultivation. How...
عوامل مختلفی بر رشد ، درصد بقاء و کیفیت نوزادان فرشته ماهی (pterophyllum scalare)تاثیر دارد. در این تحقیق، تأثیر دماهای مختلف ،بر میانگین وزن ، طول و بقاء نوزادان فرشته ماهی مورد مطالعه قرار گرفت . نمونه ها در سه تیمار دمایی شامل 27 ، 29 و 31 درجه سانتی گراد و هر تیمار با سه تکرار قرار داده شدند . بدین ترتیب 9 دستگاه آکوآریوم به ابعاد 30 ×40× 60 سانتی متر به این مطالعه ، اختصاص داده ...
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 ...
We analysed the 16S rRNA gene diversity within the bacterioplankton community in the water column of the ornamental fish Pterophyllum scalare and Archocentrus nigrofasciatus aquaria during a 60-day growth experiment in order to detect any dominant bacterial species and their possible association with the rearing organisms. The basic physical and chemical parameters remained stable but the bacte...
در این تحقیق عملکرد شارهای نوری مدل های مختلف لامپ های فلوئورسنت خطی بر افزایش بایومس گیاه آبزی ceratophyllum demersum و رشد فرشته ماهی (pterophyllum scalare) بررسی شد. بدین منظور از لامپ های فلوئورسنت مدل 8t5، t4 ،t و یک گروه شاهد (بدون استفاده از لامپ)، در سه تکرار و به مدت 8 هفته استفاده گردید. با به کارگیری لامپ فلوئورسنت مدل 5t علاوه بر افزایش بایومس گیاه c.demersum، پارامترهای رشد مانند...
