This study aims to present comprehensive notes for the use of probiotics in aquaculture. Probiotics have been proven to be positive promoters of aquatic animal growth, survival and health. In aquaculture, intestines, gills, the skin mucus of aquatic animals, and habitats or even culture collections and commercial products, can be sources for acquiring appropriate probiotics, which have been ide...
Introduction: Iron metabolism was found to be implicated in several cancers. Few epidemiologic studies; focusing on iron intake and lung cancer (LC), reported positive associations between heme iron and red meat. Based on estimates of iron contents in representative foods, we conducted the present study with the aim of analyzing dietary iron and its role on the incidence of LC in Uruguayan men,...
Aquatic animal diseases are the most significant constraint to the development and management of aquaculture worldwide. As aquaculture is growing rapidly and poised to help in bridging the gap in the global supply and demand of aquatic animal food products, management of health and reducing losses due to disease in aquaculture is gaining high priority. One of the key areas of success in managin...
A large variety of aquatic animals was found to emit the potent greenhouse gas nitrous oxide when nitrate was present in the environment. The emission was ascribed to denitrification by ingested bacteria in the anoxic animal gut, and the exceptionally high N(2)O-to-N(2) production ratio suggested delayed induction of the last step of denitrification. Filter- and deposit-feeding animal species s...

In October 2006 the World Organisation for Animal Health (OIE) held the first Global Conference on Aquatic Animal Health. The conference was arranged as a result of growing awareness of the constraints on managing aquatic animal diseases, due to both knowledge gaps and fragmented governmental responsibilities in many countries. This paper summarises and expands on some of the issues raised at t...
The 12 June Reviews by R. Kays et al. (“Terrestrial animal tracking as an eye on life and planet,” p. 1222) and N. E. Hussey et al. (“Aquatic animal telemetry: A panoramic window into the underwater world,” p. 1221) highlight some challenges to the future of terrestrial and aquatic telemetry studies, respectively, focusing on issues related to global collaboration and data sharing. Kays et al. ...
Animals can be important in modulating ecosystem-level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing the predictions of important frameworks such as the Metabolic Theory of Ecology (MTE) and ecological stoichiometry (ES). They also represent an important set of functional ...
background: aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. these insects have been, in some cases, well studied because they are vectors of several diseases. this is the first comprehensive faunistic study of aquatic insects from babol county. the results may provide basic data fo...
