Abstract
- The general objective was to evaluate the zootechnical parameters of red tilapia fingerlings Oreochromis sp, in the rearing stage, supplemented with buttercup Tithonia diversifolia. The trial was carried out in the laboratory of the Centro Experimental Piscícola in San Jerónimo, Antioquia (Colombia). The 135 fingerlings were collected and placed in nine aquariums of 63 L of water. T1 - 15% supplementation, T2 - 20% supplementation and a Control - without supplementation, were evaluated for six weeks. The number of fingerlings, the initial and final weights and sizes and the physicochemical parameters of the water were recorded and statistically evaluated. The results showed a significant difference (p<0.05) for T2 compared to T1 and Control. Greater final weight and height (1.0±0.4g and 3.9±0.4cm), K>1, TEC=2.1%/day and survival (100%). The physicochemical parameters of the water maintained the optimal average values of temperature (1=25.0±0.3 °C), oxygen level (1=7.0±1.3 mg/L) and pH (1=7.8±0.3). [ABSTRACT FROM AUTHOR]
