Inclusión del quitosano en la alimentaciòn de alevienes de tilaìa roja ( Oreochromis sp.).

The objective of this study was to evaluate the effects of chitosan as a biostimulant in the diet on the productive, nutritional zootechnical and hematological parameters of the cultivation of red tilapia (Oreochromis sp.) In its fry phase in a controlled system. The chitosan was integrated into a diet formulated in four different levels that was supplied to the fry over a period of 55 days, after this for the respective statistical analysis a completely randomized design (ANOVA) was applied and the Tukey multiple range test. The results obtained varied according to the percentage of chitosan (0, 1, 3 and 5%) giving the best response in most zootechnical parameters to 5% of chitosan with a 1.98% increase in size at the end of the experiment, growth rate specific (TCE%) 15.03 ± 6.48 and absolute growth rate (TCA) weight gain (GP) of 8.27 g. In survival, chitosan inclusion in 3% showed no significant difference with respect to the control, but with respect to the other treatments; In the nutritional parameters, food conversion values (CA) were more favorable for 1% (T2: 0.33) and 3% (T3: 0.44). In the metabolic results of blood chemistry, no significant differences (p≥0.05) were found in glucose and cholesterol, but (p <0.05) in the triglyceride levels of the T4 treatment with respect to the other treatments. The results shown finally indicated that diets with the highest level of inclusion of chitosan as a biostimulant in the diet could improve the zootechnical and hematological parameters of young red tilapia (Oreochromis sp.) Fry for better production. Keywords: Fry, feeding, hematological, parameters, chitosan, tilapia.
