Abstract
El objetivo general de la investigación fue determinar de manera experimental la densidad de siembre de Mugil cephalus “lisa”, alimentados con microalgas a dos densidades de siembra, donde se evaluó el comportamiento de adaptabilidad en ambiente controlado, crecimiento y sobrevivencia, con una dieta alimenticia de microalgas como: Chlorella sp. y Scenedesmus sp.; determinándose paralelo a ello, los parámetros como temperatura y pH, con proyecciones al cultivo tecnificado de “lisa”. La investigación fue desarrollada en el Departamento de Pesquería de la Universidad Nacional de Trujillo, en el laboratorio de acuicultura SL04LA04, se utilizó dos tanques de IBC de 1m3 de capacidad con un volumen útil de 750 L. En el primer tiramiento se utilizó 40 lisas/m3, y en el segundo tratamiento 60 lisas/ m3, se realizó muestreos biométricos cada 15 días, donde se alimentó dos veces al día. El análisis estadístico se trabajó a través de un análisis de varianza - ANOVA. El crecimiento promedio en peso de Mugil cephalus para el T1 fue 5.6 y 6.2 g y en T2 fue de 3.4 y 4.4 g. La longitud promedio para el T1 entre 2.0 y 11.0 cm y en el T2 fue de 1.5 y 5.6 cm. Se determinó que para el cultivo de Mugil cephalus “lisa” alimentados con microalgas en condiciones de laboratorio, a dos densidades, presentaron diferencias significativas
The general objective of the research was to experimentally determine the sowing density of Mugil cephalus “lisa”, fed with microalgae at two sowing densities, where the behavior of adaptability in a controlled environment, growth and survival, with a nutritional diet was evaluated. of microalgae such as: Chlorella sp. and Scenedesmus sp.; parallel to this, parameters such as temperature and pH are determined, with projections to the technical cultivation of “lisa”. The research was developed in the Department of Fisheries of the National University of Trujillo, in the aquaculture laboratory SL04LA04, two IBC tanks of 1m3 capacity were used with a useful volume of 750 L. In the first pull, 40 mullet were used. m3, and in the second treatment 60 mullet/m3, biometric sampling was carried out every 15 days, where it was fed twice a day. The statistical analysis was carried out through an analysis of variance - ANOVA. The average growth in weight of Mugil cephalus for T1 was 5.6 and 6.2 g and in T2 it was 3.4 and 4.4 g. The average length for T1 was between 2.0 and 11.0 cm and for T2 it was 1.5 and 5.6 cm. It was determined that for the cultivation of Mugil cephalus “lisa” fed with microalgae under laboratory conditions, at two densities, they presented significant differences.
