Total Mercury in Carnivorous Fish from Brazilian Southeast
Bulletin of Environmental Contamination and Toxicology, 2015Total mercury concentrations were determined by atomic absorption spectrometry in muscle tissue of two commercially important species of carnivorous fishes croaker (Micropogonias furnieri) and cutlassfish (Trichiurus lepturus) caught in Itaipu estuary, Rio de Janeiro.

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

Environmental Science and Pollution Research, 2023
Some studies have shown that freshwater ecosystems are polluted in a similar proportion to marine ecosystems; however, there are many gaps to be filled in this topic. Here, we investigated whether plastics were consumed by carnivore fishes in a Neotropical floodplain and whether it was connected to seasonality (dry and wet seasons).

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 ...

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 ...

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.

Amino acid 15N trophic enrichment factors of four large carnivorous fishes
Journal of Experimental Marine Biology and Ecology, 2014Abstract Ecosystem-based fisheries management strategies require knowledge of trophic relationships. Trophic position (TP) estimates from compound specific nitrogen isotopic analysis of amino acids (AA-CSIA) show promise as the method can disentangle confounding factors associated with changing δ 15 N values at the base of the food web, but it has ...

Chemical Control of Feeding in Herbivorous and Carnivorous Fish
1986It is now generally recognized that chemical control of feeding is an important modulator of physiological well-being in most animal species (Lindstedt, 1971; Harborne, 1977; Kare and Maller, 1977; Croll, 1983; Simpson and Bernays, 1983). Feeding is an elective process with the animal selecting specific food items from a variety of nutrient sources ...

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 ...

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).
