Determination of optimum feeding rate for growth of Caspian carp, Cyprinus carpio (Linnaeus, 1758) fingerlings
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2012, Vol 5, Issue 3
Abstract
One of the important issues in aquaculture, need to achieve a balance between growth rate and optimal use of fish meal is provided. This study was conducted for 6 weeks in the Sijual Bony Fishes Reproduce and Cultivate Center (Gorgan, Golestan, Iran). Experiments were done 4 treatments and 3 replicates as follows: treatment A = 2.5 % body weight per day, treatment B = 5 % body weight per day, treatment C = 7.5 % body weight per day and treatment D = 10 % body weight per day. Aim to this purpose Caspian carp fingerlings with an average weight of 1.5 ± 0.145 g and average length of 2.97 ± 0.154 cm were distributed in 12 fiberglass tanks (30 number fish per tank) and were cultured for 6 weeks in the same conditions and fed with SFC diet (content: 8.7 % moisture, 11.2 % ash, 32 % protein and 10.5 % fat) four times a day. Results showed that hadn't significant effects in Specific Growth Rate (SGR), Body Weight Index (BWI %), Growth Rate (GR) and Condition Factor (CF)(P<0.05) but hadn't significant effects in Feed Conversion Ratio (FCR) and survival (P>0.05). The results show that there are significant differences with regard to the amount of body weight and body length of fingerlings in different treatments (P<0.05), so that the maximum body weight and body length of carp fingerlings is 7.5 % body weight per day
