Evidence of sugar sensitive genes in the gut of a carnivorous fish species
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2013The ability of intestine to sense glucose in carnivorous animals (consuming minimal carbohydrate) has been partially evaluated to date only in cats. We have evaluated the expression of markers involved in the detection of simple sugars in the intestine of the strict carnivorous fish species rainbow trout (Oncorhynchus mykiss) in response to an oral ...

From Fishing to the Sustainable Farming of Carnivorous Marine Finfish
Reviews in Fisheries Science, 2010Carnivorous marine finfish aquaculture has been the subject of intense criticism. Because the process consumes more fish biomass in the form of fishmeal and fish oil than it produces, critics argue carnivorous marine finfish aquaculture causes a net loss of living marine resources and is unsustainable given the continued expansion of the industry ...

Microplastics in carnivorous fish species, water and sediments of a coastal urban lagoon in Nigeria
Environmental Science and Pollution Research, 2023Plastic marine debris is a common source of pollution. Recent research has shown that plastic debris has a negative impact on marine organisms and the environment. For the first time, we investigated the presence of microplastics (MPs) in the Nigerian Lagos Lagoon ecosystem water, sediment, and the most important fish species (Hepsetus odoe ...

Intestinal glucose transport in carnivorous and herbivorous marine fishes
Journal of Comparative Physiology ? B, 1983The influx and transepithelial movements of glucose and their effects on the electrophysiology and Na transport in upper and lower intestines of the herbivorous surgeonfish,Acanthurus mata, and carnivorous eel,Gymnothorax undulatus, were measured. TheK t G andJ max G of glucose influx into the tissues were higher in the surgeonfish upper intestine than

Increased timidity is a behavioral response to exploitation caused by a combination of learning and fisheries-induced selection favoring shy fish. In our study, the potential for angling-induced change in fish behavior was examined in two marine coastal fishes exploited by boat recreational fishing in the Mediterranean (Mallorca, Spain).

Environmental Pollution, 2016
Mercury contamination in the River Beni basin is an important health risk factor, primarily for indigenous communities that live along the river. Among them are the Tacana, living in their original territory with sustainable use of their natural resources, consuming fish, Caiman yacare, and other riverine resources as their main source of protein.

Trophic Traits and Phylogenetic Relatedness in Tropical Carnivorous Fish Assemblages
Marine Environmental ResearchEcological similarities among species often stem from their shared evolutionary history, as evidenced by the phylogenetic signal. This signal indicates that closely related species tend to exhibit greater similarity in ecological traits compared to unrelated species. From a trophic niche perspective, this relationship remains unclear.

The use of microalgae as dietary ingredients for marine carnivorous fish
2012Recent improvements in technological production systems allow massive microalgae biomass to be produced under controlled conditions. This makes such organisms a potential alternative to conventional sources of omega-3 polyunsaturated fatty acids also for feeding marine finfish species of interest for ...

How Tom Moon's research highlighted the question of glucose tolerance in carnivorous fish
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2016Fifteen years ago, Tom Moon wrote a review on this journal in order to propose some explanations to the exacerbated glycaemic response after a glucose load or a carbohydrate meal intake observed in fish, the so-called intolerance to glucose. Before, but in most of cases after this paper, several laboratories worldwide started to make important efforts ...

Physiological responses to short-term fasting among herbivorous, omnivorous, and carnivorous fishes
Journal of Comparative Physiology B, 2014We 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 refeeding. Fasted and fed herbivorous grass carp (Ctenopharyngodon idella), omnivorous channel catfish (Ictalurus punctatus), and carnivorous largemouth bass ...
