Special Issue Information

Dear Colleagues,

We hope this message finds you and your family well in these COVID times.

It is well known that aquaculture is one of the principal and very rapidly growing human activities carried out in the marine environment. Aquaculture can be seen from different points of view—as seafood production, as production of economic benefits, as employment opportunities, etc. However, in any case, successful aquaculture activities are highly dependent on the environment and the use of natural resources (i.e., capture-based aquaculture), having inevitable effects on different components of marine ecosystems. Some of these effects (i.e., local eutrophication, FAD effect, effects on the seabed, etc.) have been studied and described in a number of previously published papers, but many of them focused mainly on local effects in the vicinity of fish farms.

Therefore, the aim of this Special Issue is to gather and provide the most recent information about the very diverse effects of marine aquaculture activities on different components of marine ecosystems. These effects might be positive or negative, direct or indirect, evident on small (local) or wide spatial scales, and may have influences on nutrients, native populations of marine organisms (plankton, algae, invertebrates, fish, sea birds, marine mammals, etc.), and the trophic structure in the ecosystem. New knowledge on these relations between different marine aquaculture activities (shellfish aquaculture, finfish aquaculture, capture-based aquaculture, etc.) and marine ecosystems is likely to play an important role in proper planning in the context of ecosystem-based management (EBM) in the future.

Having in mind your expertise in this field, we would like to kindly invite you and your colleagues to contribute papers to this Special Issue.

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. Journal of Marine Science and Engineering 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.

Sediment oxygen demand (SOD) and benthic nutrient fluxes (BNFs) were measured using an in situ benthic chamber at a fish farm (FF), oyster farm (OF), and controls (FF-C and OF-C) to assess the impact of aquaculture activities on organic carbon (OC) and nutrients cycles in coastal waters of Korea. The SOD at FF and OF ranged from 60 ± 2 to 157 ± 3 mmol m−2 d−1 and from 77 ± 14 to 84 ± 16 mmol m−2 d−1, respectively, more than five times those of the control sites. The SOD at farm sites is highly correlated with fish stock and food input, suggesting that excess feed input is an important control factor for OC remineralization. The combined analysis of sediment trap and SOD indicates that most of the deposited OC oxidized in the sediment and/or was laterally transported by the current before being buried in the sediment. The benthic nutrient fluxes at farms ranged from 5.45 to 8.95 mmol N m−2 d−1 for nitrogen and from 0.51 to 1.67 mmol P m−2 d−1 for phosphate, respectively, accounting for 37–270% and 52–804% of the N and P required for primary production in the water column. These results indicate that aquaculture farming may profoundly impact biogeochemical cycles in coastal waters. Full article
