Special Issue Information

Dear Colleagues,

I warmly invite you to submit your work to this Special Issue on the movement ecology of large pelagics. The focus of this collection is to highlight the emerging science and unconventional findings on movement ecology that you might have found difficult to publishing elsewhere.

Movement ecology should not merely describe where an animal has gone or what it is inferred to have done in a particular place and time. It is important to go beyond individual movement histories and probe the underlying mechanisms and motivations underpinning why animals might move as a group of individuals or a cohort. We, therefore, encourage research that employs novel experiment designs, analytical techniques, and theoretical investigations to provide our community with new ideas to test in the lab and in the field.

Equally important is the need for movement science to inform management practices and conservation. The synthesis of multi-disciplinary data from genomics, biochemistry, and fishery statistics with individual tracking is the most productive approach to deliver the required holistic information for managers and decision makers. One often-overlooked aspect is the abundance of historic data sets, logbook records, and ever-growing remote sensing data. As scientists, we can be the master tapestry makers of this vast array of scientific data. If artificial intelligence can aid us in achieving this type of synthesis, templates and approaches should be shared to seed further applications.

This Special Issue is about the bigger picture and future possibilities, so we encourage you to let your imagination fly and ground it with scientific discoveries.

Dr. Chi-Hin Lam

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.

The reef fish communities of the Guanahacabibes National Park have been studied for 20 years using various methodologies that have allowed us to understand aspects of their diversity and structure. However, due to gaps in information about the abundance and distribution of mesopredators (big fish and sharks), a new study was conducted in 2017 to determine their structure, explore the influence of different factors on their spatial variability, and evaluate their behavior. To achieve this, the Baited Remote Underwater Video Surveys (BRUVs) methodology was successfully applied, locating a single set of BRUVs at 90 sites distributed across 9 sectors of the park’s functional zoning. Variability in mesopredator metrics and their potential prey was assessed through a PERMANOVA analysis; a distance-based linear model (DISTLM) was used to explore the relationship between mesopredator abundance and biological, abiotic, and condition variables; and animal behavior was classified as incidental, cautious, or aggressive. A total of 64 fish species were identified, 7 of which were mesopredators, and 3 were sharks. An uneven distribution and abundance were observed among sectors, with the most abundant mesopredators being Carcharhinus perezi, Sphyraena barracuda, and Mycteroperca bonaci. Mesopredator abundance was more closely related to the condition of zone use and its regulations than to biological and abiotic variables. Sharks were more abundant in strictly protected areas, which coincided with relatively murky waters and stronger currents. More than 50% of the observed sharks displayed exploratory and aggressive behavior towards the bait basket. The analyzed metrics validate the effectiveness of the management of the protected area and suggest the presence of healthy and resilient mesopredator fish communities. Full article
