The treatments consisted of four experimental diets and one control diet 1) fish meal, 2) a combination of pork and poultry meals, 3) <em>Nannochloropsis gaditana</em> meal, 4) enzyme preparation and the control treatment 5) <em>Artemia nauplii</em>. The evaluation indicated that the larvae fed the <em>Artemia nauplii</em> obtained the greatest growth and survival (3.93 cm, 0.19 g y 82 % respectively), which justifies a correct culture system operation. While larvae fed microencapsulated diets best values in survival were observed with diets <em>Nannochloropsis gaditana</em> and enzyme preparation (20.0 and 19.2 %). Our results showed that microencapsulated could be used to feed <em>A. tropicus</em> in feasibly form. However, more information concerning to optimize the design and manufacturing are required to improve the growth and survival of organisms.}, number={3}, journal={Revista de Biología Tropical}, author={Saenz de Rodrigáñez, Miguel and Aguilar-Tellez, Federico Vladymir and Alarcón-López, Francisco Javier and Pedrosa-Islas, Ruth and Peña-Marín, Emyr Saul and Martínez-García, Rafael and Guerrero-Zárate, Rocío and Matamoros, Wilfredo A. and Álvarez-González, Carlos Alfonso}, year={2018}, month={Sep.}, pages={1298–1313} }
