Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Crustaceans as Key Prey: Insights Into the Dietary Partitioning of Four Carnivorous Fishes in the Nansha Islands, South China Sea

Ecology and Evolution
Small carnivorous fishes serve as important mesopredators in coral reef ecosystems. However, the habitat and prey availability degradation within these ecosystems has intensified the trend of body size miniaturization and interspecific competition among ...

Ecological adaptation of an F1 hybrid cross of carnivorous and herbivorous Cyprinidae fishes [PDF]

, 2020
Abstract Background Whether hybridization plays a positive or negative role in speciation remains a controversial issue to date. Genetic factors have been widely studied, but ecological factors also play an important role. Although studies on the ecological adaptation of hybrids between different niche parents have been widely reported, cases ...

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Oral administration of wild plant‐derived minerals and red ginseng ameliorates insulin resistance in fish through different pathways

Physiological Reports, 2023
Many kinds of fish are characterized by a limited efficiency to use carbohydrates. For this reason, raw fish and mixed feed containing a lot of fish meal have been used as feed for fish farming.

Utilization of Glycerol for Endogenous Glucose and Glycogen Synthesis in Seabass (Dicentrarchus labrax): a Potential Mechanism for Sparing Amino Acid Catabolism in Carnivorous Fish

, 2020
Glycerol is a well-tolerated additive in aquafeeds. We hypothesized that in seabass, a carnivorous fish whose endogenous carbohydrate demands are mostly met by hepatic amino acid gluconeogenesis, glycerol effectively competes with these substrates for ...

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

CONSERVATION OF AN ENDANGERED CARNIVOROUS FISH RITA RITA THROUGH INDUCED BREEDING

Biological and Clinical Sciences Research Journal, 2020
In present study the Effects of different doses of ovaprim on induced spawning activities of Rita rita were observed with an aim to standardize the dose of ovaprim for successful breeding. In the trial experiment, the females of Rita rita were treated with ovaprim at the rate of 0.5, 0.8 and 1.0ml/kg body weight and males of Rita rita in all the cases ...

Animal v. plant-based bait: Does the bait type affect census of fish assemblages and trophic groups by baited remote underwater video (BRUV) systems? [PDF]

, 2016
© 2016 The Fisheries Society of the British Isles. Coral reef fish communities were sampled at the Nayband Marine Park, Iran, using baited remote underwater video stations (BRUVSs) which incorporated animal (i.e. frigate tuna Auxis thazard and beef liver)

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome
