The need to obtain massive cultures of microlgas on a cheaper way,leads to search for new culture media that should reduce their cost of production. In this way, the goal of this research was to evaluate an organic fertilizer made from the silage of by products of trout Oncorhynchus mykiss (FBRT) as a culture medium for growing the microalga Tetraselmis suecica. The present research was carried out in the area of Live Food in the Aquaculture laboratory, of the School of Fisheries of the National Agrarian University la Molina. All tests were performed at a salinity of 30UPS, temperature 21±2ºC and 3Klux of luminity. Initially, from several media concentration (0.5, 1, 2, 3, 4, 5 y 10 ml of fertilizer/L sea water ) it was determined that 3ml FBRT / L sea water (3: 1000) was the optimum concentration of FBRT for microalgae growth and higher concentrations than 5ml caused microalgae mortality. Concentration of 3ml was compared with a commercial fertilizer (BAYFOLAN®FORTE) and an inorganic fertilizer (Yashima medium), each made in triplicate in 300ml vessels. Cell density (cel ml-1) and protozoa contamination were evaluated. At the end of the experiment, the highest growth was obtained with FBRT fertilizer reaching 142,816 x 104cel ml-1, followed by the Yashima medium with 65.95 x 104cel ml-1; and the less growth obtained with the BAYFOLAN®FORTE fertilizer (35.63 x x104cel ml-1. Regarding protozoa contamination, the culture FBRT medium obtained the highest concentrations of protozoa without affecting the growth of the microalgae. it was concluded that the FBRT fertilizer can be used as a culture medium for growth the microalga Tetraselmis suecica. It is recommended to evaluate its use for massive crops.
