Abstract
The study was conducted for 134 days. Common carp fry (60g ± 0.3g) were fed using two different diets containing only plant protein sources, without any animal protein inclusions. Diets were administered by two different methods: an automatic band feeder (diet 28/7 F and 28/15 F) for 12 hours a day (9.00 a.m. – 9.00 p.m.) and by hand (diet 28/7 H and 28/15 H) once a day (at 9 am). Weight, Specific Growth Rate (SGR), Protein Efficiency Ratio (PER), Fat Retention Index (FR) and Protein Retention Index (PR) were statistically higher in fish fed with the automatic feeder. On the contrary, the value of FCR was statistically higher in fish fed by hand. Diet composition did not have significant influence on growth performance. Survival rate was not statistically different among groups (85-96%). There was no significant effect of feeding method or diet on meat quality, such as color and fat content.
