Many animals face periods of feeding restrictions implying fasting and refeeding. The
determination of digestive/metabolic and body condition parameters at different times of food …

The family Mugilidae consists mainly of diadromous species, whose reproduction occurs in
offshore waters. Pre‐juveniles shift their diet in the surf zone (zooplanktophagous to …

After a meal, a sequence of physiological changes occurs in animals in response to
digestion, absorption and assimilation of the ingested nutrients. These processes are very …

Fish that are active foragers usually perform routine activities while digesting their food; thus,
their postprandial swimming capacity and related behavior adjustments might be …

We explored the integrated role of dietary specialization and feeding periodicity on the
response of the gastrointestinal tract of teleosts fishes to short-term (7–10 days) fasting and …

Digestive flexibility is considered an adaptive response that allows individuals to minimise
maintenance costs during periods of food scarcity. Here, we evaluated changes in body …

The size and functional capacity of the gastrointestinal (GI) tract and associated organs vary
in response to environmental cues. The GI tract and associated organs are also very …

Annual killifishes have active and voracious rates in acquisition of food resources with
display of behaviors that allow them to maintain high metabolic rates to deal with the harsh …

This study explores the interplay between digestive tract traits, food intake, and assimilation
in omnivorous tetra fishes (Psalidodon bifasciatus, P. aff. gymnodontus, and Bryconamericus …

Abstract Heteropneustes fossilis (115–144 mm and 11.38–15.30 g) need 44.44±5.56 min for
satiation. The voluntary intake (appetite) shows a sigmoid relationship with time and it …
