NON-STARCH POLYSACCHARIDE IN DIETS FOR HYBRID SURUBIM: EFFECTS ON METABOLISM PLASTICITY
Boletim do Instituto de Pesca, 2019 This study aimed to analyze the effect of mango meal, a non-starch polysaccharide, as a carbohydrate source on the metabolism plasticity and performance indicators for hybrid surubim (Pseudoplatystoma fasciatum x P. corruscans), a tropical carnivorous fish. Juveniles (±14.5g initial weight) were fed 3% of total biomass for 60 days in four experimental

Irrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin
Environmental DNA, Volume 7, Issue 4, July–August 2025.Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...

Journal of Applied Ichthyology, Volume 2024, Issue 1, 2024.Studies on the production of Pimelodidae catfish in the Amazon are generally carried out in large fishing centers. However, the data referring to small‐scale fisheries have gaps that can represent a risk to the activity. This study evaluated the volume produced and the revenue obtained from migratory catfish of the Pimelodidae family of commercial ...
