Resumen
En los últimos años se ha comprobado la existencia de un fenómeno interesante referido a las explotaciones agropecuarias en la diversificación y crianza de animales no tradicionales, y entre ellas se encuentra la acuicultura como una alternativa en el sector pecuario en la producción de carne blanca. El objetivo de esta investigación fue comparar dos tipos de dietas del camarón Litopenaeus vannamei desde la etapa juvenil a producción en cultivo de arroz con camarón.
En la investigación de tipo experimental se utilizó 760 camarones juveniles de la especie L. vannamei, las cuales se las dividió comparando 2 tipos de alimentación, una con balanceado + harina de soya hidropónica al 5% y la otra solo con balanceado comercial. A su vez se evaluó la calidad de agua de las piscinas de camarón en conjunto a las del cultivo de arroz.
Por medio del software INFOSTAT utilizando el test de Duncan se pudo corroborar que el diseño si presenta significancia estadística tanto en peso (P 0.0061) como en talla (P 0.0258), en la piscina tratamiento hubo un incremento en peso de 3,59 gr y en la piscina de testigo de 3,54 gr. En cuanto a la talla en la piscina de tratamiento hubo un incremento de 1,84 cm, mientras que, en la piscina de control hubo un aumento de 2,92 cm, además se puede aseverar lo indicado por la prueba de Duncan a través del coeficiente de variación (CV) cuyo resultado fue de 8,03% para el peso y 5,67% CV para la talla. Hubo una tasa de mortalidad del 10% en la piscina tratamiento, y 20% en la piscina de control.
Se puede concluir que la implementación de harina hidropónica de soya al 5% mejora el rendimiento productivo del camarón
In recent years, the existence of an interesting phenomenon has been verified in relation to agricultural farms in the diversification and breeding of nontraditional animals, and among them is aquaculture as an alternative in the livestock sector in the production of white meat in the population of Ecuador. The objective of this research was to compare two types of diets of the shrimp Litopenaeus vannamei from the post-juvenile stage to production in rice cultivation with shrimp. In the experimental research, 760 juvenile shrimp of the L. vannamei species were used, which were divided by comparing 2 types of feed, one with balanced + 5% hydroponic soybean meal and the other only with commercial balanced. In turn, the water quality of the shrimp pools was evaluated together with those of the rice culture. By means of the INFOSTAT software using the Duncan test, it was possible to corroborate that the design does show statistical significance both in weight (P 0.0061) and height (P 0.0258), in the treatment pool there was an increase in weight of 3.59 gr and in the control pool of 3.54 g. Regarding the size in the treatment pool there was an increase of 1.84 cm, while in the control pool there was an increase of 2.92 cm, in addition, what is indicated by the Duncan test can be asserted through the coefficient of variation (CV) whose result was 8.03% for weight and 5.67% cv for height. There was a mortality rate of 10% in the treatment pool, and 20% in the control pool. It can be concluded that the implementation of 5% hydroponic soybean meal improves the productive performance of shrimp
