Este trabajo se realizó con el objetivo de lograr alimentos nutricionalmente más eficientes y económicos en el cultivo del camarón blanco Litopenaeus schmitti. Se desarrolló durante 63 días en estanques de tierra fertilizados de 250 m2 . Se emplearon juveniles de 0.4 ± 0.01 g de peso promedio procedentes del área de precriaderos. Los camarones fueron sembrados a igual densidad que en la escala productiva con sistema semiintensivo (10 camarones/m2). La preparación y manejo de los estanques se efectuó de igual forma que en la producción. Se emplearon tres formulaciones, utilizando como control la del alimento comercial y otras dos donde se reduce parcialmente la harina de pescado y se sustituye por harina de soya. Cada tratamiento contó con tres repeticiones. Se observó que el crecimiento se favoreció significativamente al aumentar la inclusión de harina de soya. Los valores del Factor de Conversión del Alimento, mejoran con la sustitución. La supervivencia presentó un comportamiento muy similar en todos los casos con valores entre 83 y 84%. Se concluye que elevar la inclusión de harina de soya en la dieta comercial de engorde del camarón L. schmitti en sustitución parcial de la harina de pescado, mejora los índices productivos y eleva la rentabilidad en el cultivo.Assessment of different artificial foods in the growth of juveniles of white shrimp Litopenaeus schmitti This work was carried out with the objective to obtain foods more nutritionally efficient and economic in the culture of the white shrimp Litopenaeus schmitti. It was developed during 63 days in fertilized earthen ponds of 250 m2. Juveniles of 0.4 ± 0.01 g of initial average weight were used coming from nursery ponds area. The shrimps were sowed to same density that in the productive scale with semiintensive system (10 shrimps/m2). The preparation and handling of the ponds was carried out of equal form that in the production. Three formulations were evaluated, using the commercial diet like control and another two where decreases partially the fishmeal and it’s substituted for soybean meal. Each treatment had three repetitions. It was observed that the growth was favoured significantly with increase in the inclusion of soybean meal. The values of Feed Conversion Ratio improve with the substitution. The survival presented a similar behaviour in all the cases with values between 83 and 84%. Its concluded that to elevate the inclusion of soybean meal in the growth commercial diet of shrimp Litopenaeus schmitti in partial substitution of the fishmeal improvement the productive indexes and elevate the profitability in the culture.
