Se evaluó el desempeño productivo, calidad de agua, alimento natural y composición proximal del camarón gigante de Malasia (Macrobrachium rosenbergii) en dos tipos de sistemas: tradicional y con tecnología de bioflocs (BFT), con y sin substratos artificiales (mallas de polietileno) para el engorde de esta especie en altas densidades. De esta manera, el experimento consistió en 4 tratamientos en triplicado: sistema tradicional (ST), sistema tradicional con substrato (ST/S), sistema con bioflocs (BFT) y sistema con bioflocs y substrato (BFT/S). Se montaron 12 unidades experimentales (tanques de 800 L) en donde se cultivaron 41 camarones/m2 (4.13 g) durante 64 días. Todos los parámetros físicoquímicos se mantuvieron dentro del rango adecuado, la presencia de substratos en ambos sistemas mejoró la calidad de agua al disminuir significativamente la concentración de NAT, N-NO2 y N-...

The tidal channels in the department of Tumbes, Peru harbor various species of penaeids, such as Penaeus stylirostris and P. vannamei, the latter of great economic importance for the country. In 2017, 560 specimens of wild prawns were evaluated in two sampling periods (May-June and September-November), from seven tidal channels to determine the prevalence of notifiable diseases: White Spot Syndrome (WSSV), Infectious Hypodermal and Hematopoietic Infection (IHHNV), Hepatopancreatic Necrosis (NHP), Taura Syndrome (TSV), Infectious Myonecrosis (IMNV) and Yellow Head Syndrome (YHV) using the PCR technique. The presence of three of the seven pathogens was detected. The highest prevalence of the study was VNHHI (6.35%) distributed in the seven tidal channels, followed by HPN (2.65%) in five tidal channels and VSMB (0.55%) present in three channels, but only in the first sampling period.
