description Since many of the species used for aquaculture purposes are exotic and without considering the degree of alteration that they can cause in ecosystems and native species, this study was carried out with the aim of introducing a native species such as Dormitator latifrons to traditional pond aquaculture systems. Polyculture systems with species of higher commercial value have provided a useful strategy for the development of sustainable aquaculture of native fish.  For this reason, this study evaluated the yield of production and growth of D. latifrons in polyculture with red tilapia (Oreochromis spp.) and freshwater prawn (Macrobrachium rosenbergii) in Costa Rica. Juveniles with initial weights of 36.5 g ± 7.7 for D. latifrons, 14.2g ± 7.5 for tilapia and 13.1 g ± 8.4 for prawns were used during the experimental phase carried out in 2 ponds divided into 3 sections of 24 m2. The organisms were randomized using a treatment with 3 replicas in polyculture composed of 42 D. latifrons (1.75 Ind/m2), 34 tilapias (1.42 Ind/m2) and 27 prawns (1.12 Ind/m2), while the control was used, by triplicate, with 30 D. latifrons in monoculture at a stocking density of 1,25 Ind/m2. The polyculture of D. latifrons with tilapia and prawns had a detrimental effect on the growth of the fish which demonstrates a negative interaction between them, with competition for space and food.  Dormitator latifrons can adapt to artificial feeding and compete with other species such as tilapia in the juvenile stage, but does not show the same behavior as it grows which could explain the fall in growth in the last 9 weeks in polyculture with more individuals in the pond.  The productivity of polyculture, in terms of the final biomass achieved, was considerably higher than in monoculture as more organisms were stocked and harvested.

Los sistemas de policultivo con especies de mayor valor comercial han proporcionado una estrategia útil para el desarrollo de la acuicultura sostenible de peces nativos. Por esta razón, este estudio evaluó el rendimiento de producción y el crecimiento de D. latifrons en policultivo con tilapia roja (Oreochromis spp.) y langostino (Macrobrachium rosenbergii) en estanques de producción en Costa Rica. Juveniles con pesos iniciales de 36,5 g ± 7,7 para D. latifrons, 14,2 g ± 7,5 para tilapias y 13,1 g ± 8,4 para langostinos, fueron utilizados durante la fase experimental realizada en 2 estanques divididos en 3 secciones de 24 m2. Los organismos fueron aleatoriamente distribuidos mediante un tratamiento con 3 réplicas en policultivo compuesto por 42 D. latifrons (1,75 Ind./m2), 34 tilapias (1,42  Ind./m2) y 27 langostinos (1,12 Ind./m2), mientras que en el control se utilizó, por triplicado, 30 D. latifrons en monocultivo a una densidad de siembra de 1,25 Ind./m2. El policultivo de D. latifrons con tilapias y langostinos tuvo un efecto perjudicial en el crecimiento de los peces lo que demuestra una interacción negativa entre ellos, existiendo competencia por espacio y alimento. Dormitator latifrons puede adaptarse a la alimentación artificial y competir con otras especies como las tilapias en la etapa juvenil, pero no muestra el mismo comportamiento conforme crece, lo cual podría explicar la caída del crecimiento en las últimas 9 semanas en policultivo con mayor cantidad de individuos en el estanque. La productividad del policultivo, en términos de la biomasa final alcanzada, fue considerablemente más alta que en monocultivo al sembrarse y cosecharse mayor cantidad de organismos.Escuela de Acuicultura y Pesquería, Facultad de Ciencias Veterinarias, Universidad Técnica de Manabí2023-05-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.utm.edu.ec/index.php/aquatechnica/article/view/545010.33936/at.v5i2.5450AquaTecnica; Vol. 5 No. 2 (2023): AquaTechnica, May-August 2023; 66-79AquaTechnica, Revista Iberoamericana de Acuicultura; Vol. 5 Núm. 2 (2023): AquaTechnica, mayo-agosto 2023; 66-79AquaTecnica; v. 5 n. 2 (2023): AquaTechnica, janeiro - abril 2023; 66-792737-609510.33936/at.v5i2reponame:Revista Aquatechnicainstname:Universidad Técnica de Manabiinstacron:UTMspahttps://revistas.utm.edu.ec/index.php/aquatechnica/article/view/5450/6757https://revistas.utm.edu.ec/index.php/aquatechnica/article/view/5450/6787Derechos de autor 2023 Alexander Varela, Álvaro Monterohttp://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2024-07-29T13:43:16Zoai:ojs2.revistas.utm.edu.ec:article/5450Portal de revistashttps://revistas.utm.edu.ec/index.php/aquatechnica/Universidad públicahttps://www.utm.edu.ec/Ecuador2737-60952737-6095opendoar:2026-08-10T00:50:22.815617Revista Aquatechnica - Universidad Técnica de Manabitrue
