Este estudio proporciona información sobre reproducción artificial y crecimiento de Orestias luteus en condiciones de laboratorio. La reproducción artificial se realizó en las orillas del Lago Titicaca zona Muelle Barco y las ovas fecundadas se incubaron en el Laboratorio Continental de Puno – IMARPE, en incubadoras tipo Chasse con flujo continuo de agua de 0,5 L/seg a 15 °C de temperatura promedio. Al cabo de 20 días se inició el proceso de eclosión, tuvo duración de tres días, las larvas obtenidas fueron confinadas en acuarios de vidrio de 0,115 m3 . El periodo experimental de crecimiento comprendió 240 días, para ello se utilizó 600 alevinos de carachi amarillo confinados en un acuario de vidrio de 50 x 40 x 40 cm implementado con aireación permanente. Para el mantenimiento del cultivo se proporcionó ad libitum alimento vivo (Chlorella vulgaris, Artemia salina y Daphnia pulex). La mayor talla de peces obtenida a los 240 días fue de 32 mm ±0,16 con peso de 0,3678 g ±0,167. El índice de condición biológica se encontró entre 1,0 y 1,4 y la tasa de crecimiento específico (TCE) entre 1,0 y 1,4%; asimismo, la temperatura promedio del agua de cultivo fue de 12,3 a 15,3 °C.
ABSTRACT: In Muelle Barco, on the shores of Lake Titicaca, we artificially fertilized the Orestias luteus eggs. Later, these eggs were incubated in the IMARPE’s Continental Laboratory of Puno, in Chasse-type incubators with a continuous water flow of 0.5 L/sec. at a mean temperature of 15 °C. Hatching started after 20 days and lasted three days. The larvae were confined in 0.115 m3 glass aquariums. A total of 600 fry were placed on a glass aquarium measuring 50 x 40 x 40 cm, with permanent aeration. They underwent experimental growth for 240 days. Live food (Chlorella vulgaris, Artemia salina, and Daphnia pulex) was provided ad libitum for culture maintenance. The largest fish size obtained was 32 mm ± 0.16 with a weight of 0.3678 g ± 0.167. The biological condition index was found between 1.0 and 1.4 and the specific growth rate (SGR) between 1.0 and 1.4%. The mean temperature of the culture water ranged between 12.3 and 15.3 ° C.
