16 Effects of Dietary VITASIL on the Growth Performance of Carp (Cyprinus caprio) Cultivated in a Recirculation System Assist. Prof. Alexander ATANASOV 1 Assist. Prof. Zhivko ZHELEV 2 Assist. Prof. Veselin IVANOV 3 Galin NİKOLOV 4 Abstract Problem statement: The utilization of derived from the seeds of Carduus marianus L., Asteraceae was detected for growth performance and body composition of carp (Cyprinus caprio). Approach: Vitasil was selected for determination. The experiment compared a commercial extruded diet (Bonmix 50-2) with 2, 5 and 10 ppm (Vitasil ) supplementation. Each diet was assigned to 2 tanks in a completely randomized design for 120 days. Results: The results demonstrated that the final weight and other parameters were significantly lower in comparison with the reference group (p>0.05). Conclusion: Results of the present investigation demonstrate no significant improvement of growth performance of carp can be used Vitasil supplementation.

17 Uluslararası II. Trakya Bölgesi Kalkınma - Girişimcilik Sempozyumu Introduction As the largest aquaculture industry of finfish in Bulgaria, the improvement of growth performance for carp (Cyprinus caprio) is highly concerned by the feed companies and nutritional scientists (Staykov, 2006). The most essential and major operational input in successful aquaculture is the feed and nutritionally balanced effective artificial feeds need to be developed. Several studies have shown benefits of supplementary dietary additives in enhancing the health of fish (Sakai et al., 2001; Burrell et al., 2001; Bridle et al., 2005). Therefore, an attempt has been made in this study to incorporate supplement as one of the ingredients in pelleted feed and to evaluate the efficacy of the feeds on the growth of carp. Seeds of Carduus marianus L, Asteraceae (white thorn) are used more than 2000 years for treatment of diseases and protection. The active component of this plant is silymarin - standardized extract, obtained by the seeds, containing approximately 70% - 80% aromatic flavonoids and approximately 20% - 30% dry uncertain components, including the most already polymeric and oxyphenols compounds. The main component of silymarin the complex is silybin (CAS number ). In addition silybin, which is a mixture of two diastereoisomers A and B in approximately 1:1, there are significant quantities of other flavonoids: isosilybin, dehydrosilybin, silychristin, silydianin and taxifolin. The purpose of this investigation was to determine the effects of supplemental Vitasil on growth performance and body composition for carp (Cyprinus caprio) reared in a controlled environment. 1. Materials and Methods In the present study, small, healthy, disease-free fish of carp (Cyprinus carpio) were procured from the carp hatchery at Tundja73, (Bulgaria). Trakia University in polythene bags filled with oxygen. The fish were stocked at a density of 50 in each of the concrete tanks (100X100X100 cm.) containing 1000 L of dechlorinated bore water. Adequate level of oxygen in each tank was maintained through aeration. The artificial feeds incorporated with three different supplements, namely (Vitasil-A), (Vitasil-B) and (Vitasil-C). The average weight of fish (Ave. wt. 15,3±0.12 g) at the beginning of the experiment was recorded. The fish were weighed on every 30 th day and the amount of ration adjusted accordingly. Tank-1 was considered as a control tank where the artificial feed without supplement was used. In Tank-2, artificial feed with 2%, Tank-3 feed with 5% and Tank-4 feed with 10%. The feed was given five times every day from 08:00 hrs and 16:00 hrs. 2. Results and Discussion The growth performances gained by Vitasil with different percent are presented in Tab. 1. Table 1.

Statistical analysis showed that highest weight gain was Vitasil control (55,833±9,54g). The lowest weight gain was Vitasil 2% (51,023±8,01g). When comparing growth of fish with and without supplementary feed (Table 1), a significantly higher (P>0.05) final weight of 55,833±9,54g was achieved in experiments without supplementary feed versus Vitasil 2% (51,023±8,01g), Vitasil 5% (53,000±8,14g) Vitasil 10% (53,409±8,82g) in tanks without supplementary feeding. Total weight gain of carp fed with supplementary feeding was also significantly lower (P>0.05) than without supplementary feeding. Supplementary feeding is known to increase the carrying capacity of culture systems and can enhance fish production and parameters (Jhingran, 1995). But in the present study the linear measurements presented that a supplement in different experimental variants in carp extruder diets doesn`t influence of growth performance and special indexes. This is consistent with similar studies of other freshwater fish Nikolov et al. (2008a; 2008b; 2009) and Atanasov et al. (2009). They are reported for no significant improvements growth performance and reduce mortality of carp (Cyprinus carpio) and rainbow trout (Oncorhynchus mykiss). Reference 1. Atanasov, A., G. Nikolov, V.
