Life‐History and Landscape Context Shaping the Spatial Genetic Structure of the Migratory Amazonian Fish Prochilodus nigricans

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The Neotropical migratory fish Prochilodus nigricans plays a critical ecological and socioeconomic role in the Amazon basin. Nevertheless, little is known about its populations and the genetic diversity pattern of the species. In light of this, the current study investigates the spatial genetic structure and diversity of P.

Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

Journal of Fish Biology, Volume 108, Issue 6, Page 2125-2136, June 2026.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Hidden Waters, Unique Communities: Subterranean Zooplankton Beta Diversity in the Caatinga Drylands

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Subterranean waters are important but understudied biodiversity reservoirs, particularly in the semi‐arid Caatinga biome. We quantified the biological uniqueness of zooplankton communities in these groundwater‐dependent systems and investigated how environmental conditions shape beta diversity.

Intestinal responses in pacu (Piaractus mesopotamicus) exposed to fasting and refeeding nutritional management

The Anatomical Record, Volume 309, Issue 3, Page 663-673, March 2026.
Abstract Fasting is a practice in the aquaculture industry that aims to reduce feed costs. This practice can affect the gastrointestinal system of fish. The intestine plays a pivotal role in the nutrition and overall health of fishes. The present study sought to evaluate the effects of fasting and refeeding on body weight, intestine somatic index (ISI),

Substituição da farinha de peixe pelo farelo de soja em dietas para juvenis de curimba

Boletim do Instituto de Pesca, 2018
Foi avaliada a substituição da farinha de peixe pelo farelo de soja em dietas para juvenis curimba (Prochilodus lineatus). Foram utilizadas cinco dietas isoproteicas (26% de proteí­­na bruta) e isocalóricas (4.000 kcal de energia bruta kg-1) com 0, 25 ...

Disentangling the Components Shaping Aquatic Richness Over Spatial Scales in Extreme Climatic Events

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Species richness in a region can be partitioned into three components: (1) spatial aggregation of individuals, (2) variation in total individual density and (3) species abundance distribution (SAD). However, it remains unclear how the influence of these components on richness changes under extreme climatic events.
