Abstract
Description
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 (Ẋ=25.0±0.3 °C), oxygen level (Ẋ=7.0±1.3 mg/L) and pH (Ẋ=7.8±0.3).
El objetivo general fue evaluar los parámetros zootécnicos de alevinos de tilapia roja Oreochromis sp, en etapa de levante, suplementados con botón de oro Tithonia diversifolia. El ensayo se realizó en el laboratorio del Centro Experimental Piscícola en San Jerónimo, Antioquia (Colombia). Los 135 alevinos fueron colectados y ubicados en nueve acuarios de 63 L de agua. Se evaluaron T1 – suplementación 15%, T2 - suplementación 20% y un Control - sin suplementación, durante seis semanas. El número de alevinos, los pesos y tallas, inicial y final, y los parámetros fisicoquímicos del agua fueron registrados y evaluados estadísticamente. Los resultados mostraron una diferencia significativa (p<0.05) para T2 respecto a T1 y Control. Mayor Peso y Talla final (1.0±0.4g y 3.9±0.4cm), K>1, TEC=2.1 %/día y sobrevivencia (100%). Los parámetros fisicoquímicos del agua estuvieron dentro de los valores promedio óptimos de temperatura (Ẋ=25.0±0.3 °C), nivel de oxígeno (Ẋ=7.0±1.3 mg/L) y pH (Ẋ=7.8±0.3).

O objetivo geral foi avaliar os parâmetros zootécnicos de alevinos de tilápia vermelha Oreochromis sp, na fase de recria, suplementados com ranúnculo Tithonia diversifolia. O ensaio foi realizado no laboratório do Centro Experimental Piscícola em San Jerónimo, Antioquia (Colômbia). Os 135 alevinos foram coletados e colocados em nove aquários de 63 L de água. T1 - 15% de suplementação, T2 - 20% de suplementação e um Controle - sem suplementação, foram avaliados por seis semanas. O número de alevinos, os pesos e tamanhos iniciais e finais e os parâmetros físico-químicos da água foram registrados e avaliados estatisticamente. Os resultados mostraram diferença significativa (p<0,05) para T2 em relação a T1 e Controle. Maior peso e altura finais (1,0±0,4g e 3,9±0,4cm), K>1, TEC=2,1%/dia e sobrevida (100%). Os parâmetros físico-químicos da água estiveram dentro dos valores médios ótimos de temperatura (Ẋ=25,0±0,3 °C), nível de oxigênio (Ẋ=7,0±1,3 mg/L) e pH (Ẋ=7,8±0,3).
