Abstract
En la producción de alimento vivo, representado principalmente por microalgas, se buscan nuevas técnicas de medios de cultivo sustituyendo las fórmulas tradicionales en aras de reducir costos. Teniendo en cuenta esto, se usó un medio no convencional (fertilizantes industriales) para producir las microalgas Isochrysis galbana y Nannochloropsis sp. en cultivos estáticos, y se alcanzaron densidades de 7,5 × 106 cel mL–1 de Nannochloropsis sp. en 1000 L y 0,265 × 106 cel mL–1 de I. galbana en 250 L. Hubo un crecimiento exponencial, que se alcanzó entre los tres y los ocho días, en que se duplicaron las densidades iniciales. Se sugiere cosechar en lapsos cortos (hasta cuatro días), debido a la proliferación de contaminantes y la disminución de la calidad de las células con el tiempo. Se concluye que el medio diseñado para el enriquecimiento del cultivo es una alternativa viable para la producción de las microalgas que permite satisfacer la demanda alimenticia en el levante de larvas de peces marinos.

In the production of live food, represented mainly by microalgae, this seeks new techniques of culture media, with the substitution of traditional formulas, in favor of a reduce costs. Unconventional medium (industrial fertilizers) was used to produce the microalgae Isochrysis galbana and Nannochloropsis sp. from static cultures, reaching densities of 7,5 × 106 cells mL–1 of Nannochloropsis sp. in 1000 L and 0,265 × 106 cells mL–1 of I. galbana in 250 L. Exponential growth was achieved between 3 and 8 days, doubling the initial densities. It is suggested to harvest in short periods (up to 4 days), due to the proliferation of contaminants such as protozoa and bacteria, and decrease the quality of the cells over time. It is concluded that the medium designed for the enrichment of the crop, is a viable alternative for the production of microalgae, allowing to satisfy the food demand in the raising of marine fish larvae.
