- Reproductive performance of the guppy fish Poecilia reticulata [Peters, 1859] fed with live Artemia franciscana [Kellog, 1906] cultured with inert and live diets C. J. García-Olea M. García-Ulloa Agrociencias live diets inert diets Reproduction Poecilia reticulata Artemia franciscana The reproductive performance as fry number, standard length, wet and dry weight and fry sex ratio, was studied in the guppy fish, Poecilia reticulata, under the influence of different broodstock diets. Dietary treatments consisted in live Artemia franciscana biomass fed with live microalgae (Tetraselmis suecica and Chaetoceros calcitrans), Spirulina dry powder, soy meal, wheat meal, a mixture 50%/50% of each meal and a commecial diet as the control group. After 45 days at laboratory conditions, there were no significant differences (P > 0.05) in the number of offspring born/female and individual standard length of fry among the treatments. Newborn fish from the control group were heavier than the rest of the treatments (4.14 and 1.06 mg wet and dry weight, respectively). In average, broodstock fed with brine shrimp cultured with Spirulina produced more male brood. The results point out towards the use of the commercial diet to fulfill the reproductive needs of P. reticulata. 2004 artículo científico 0188-7890 https://www.redalyc.org/articulo.oa?id=83708302 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.8
