An ex vivo Loom to Evaluate the Brewer's Yeast Saccharomyces cerevisiae in Clownfish Aquaculture with Special Reference to Amphiprion percula (Lacepede, 1802)

Abstract

This study was conducted to assess the role of dietary commercial brewer's yeast, Saccharomyces cerevisiae on the growth factors (final weight, specific growth rate (SGR) and feed conversion ratio (FCR)), survival rate, haematological parameters and serum metabolic products (glucose and total protein) of the clown fish, Amphiprion percula. Feeding trial was carried out for 90 days to study the effect of brewer s yeast on the young ones of clown fish, A. percula. Fifty young ones (avg. wt 1.345±0.03 g) were randomly distributed in each treatment and fed with different diets, prepared with six incremental levels (0%, 0.5%, 1%, 2%, 3%, and 5% of the feed) of brewer s yeast except the control. Haematology and serum parameters were studied before pathogen challenge and they were significantly higher (P
