contents	Growth of angel fish Pterophyllum scalare [Gunther, 1862] juveniles fed inert diets H. J. Gómez-Romero M. García-Ulloa Agrociencias nutrition Ornamental fish Pterophyllum scalare The growth, feed conversion ratio (FCR), survival and stress resistance of angel fish Pterophyllum scalare juveniles fed different diets (decapsulated Artemia cysts DAC, commercial flakes CF, commercial pellets CP, and a commercial starter diet for tilapia CSDT), were investigated. Diets were studied with three replicates and adjusted at 8% of daily feeding ratio. Fish had an average initial wet weight of 0.44 g. Diets showed a significant effect on fish growth performance from the first sampling day onwards. After 45 culture days, fish fed with the DAC diet showed the highest mean standard length, wet weight and specific growth rate (3.64 ± 0.07 cm, 3.19 ± 0.24 g and 4.36 % body weight/day, respectively), compared with the rest of the treatments. The FCR fluctuated from 1.26 ± 0.01 for the DAC group to 2.01 ± 0.17 for the CP diet, showing significant differences (P < 0.05) among treatments. Survival was similar for all diets. Fish fed with the DAC diet displayed higher stress resistance compared with the rest of the treatments. Although DAC seem to improve growth performance of angel fish juveniles, further trials are required to identify other factors (nutritional biology, feeding techniques and strategies) associated with its most economic use 2005 artículo científico 0188-7890 https://www.redalyc.org/articulo.oa?id=83790306 en http://www.redalyc.org/revista.oa?id=837 Avances en Investigación Agropecuaria application/pdf Universidad de Colima Avances en Investigación Agropecuaria (México) Num.3 Vol.9
