Trace Elements, Drugs, Small Compounds and Antioxidants in Fish

Dear Colleagues,

Some trace elements are toxic regardless of the amount ingested and may accumulate and biomagnify in aquatic organisms, while others are essential in small quantities. Interactions between different trace elements (e.g., Se-Hg) may reduce or increase the total toxicity exerted on an organism according to the mixture, and both their toxicity and beneficial effects often depend on the molecular species (e.g., inorganic Se compounds vs. selenoneine). Small molecules and antioxidants are essential components in fish tissues that may contribute to the health and wellbeing of the animal, its organoleptic properties and their value as a source of beneficial nutrients for consumers. In addition, some toxic (MeHg) and emergent contaminants present in aquatic environments, including human drugs (caffeine, antidepressants), have been shown to exert a measurable effect on the animal’s behaviour, which can then serve as an indication of the presence of contaminants in the environment that pose a risk to health and welfare. This Special Issue will present works screening for relevant elements and compounds in the tissues of fish, shellfish, crustaceans and gastropods, as well as experimental works on the effects of the compounds on their behaviour, health and welfare, particularly those using non-invasive methods. Submissions may consider wild and farmed organisms as well as model fish systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
