In this region, the Ivorian continental shelf is under pressure from various anthropogenic sources, which have put the regional fish stocks, especially Sardinella aurita, the dominant pelagic species in Ivorian industrial fishery landings, under threat from overfishing. Here, we combine in situ observations of Sardinella aurita catch, temperature, and nutrient profiles, with remote-sensing ocean-color observations, and reanalysis data of wind and sea surface temperature, to investigate relationships between Sardinella aurita catch and oceanic primary producers (including biomass and phenology of phytoplankton), and between Sardinella aurita catch and environmental conditions (including upwelling index, and turbulent mixing). We show that variations in Sardinella aurita catch in the following year may be predicted, with a confidence of 78%, based on a bilinear model using only physical variables, and with a confidence of 40% when using only biological variables. However, the physics-based model alone is not sufficient to explain the mechanism driving the year-to-year variations in Sardinella aurita catch. Based on the analysis of the relationships between biological variables, we demonstrate that in the Ivorian continental shelf, during the study period 1998\u20132014, population dynamics of Sardinella aurita, and oceanic primary producers, may be controlled, mainly by top-down trophic interactions. Finally, based on the predictive models constructed here, we discuss how they can provide powerful tools to support evaluation and monitoring of fishing activity, which may help towards the development of a Fisheries Information and Management System.<\/jats:p>","DOI":"10.3390\/rs10050785","type":"journal-article","created":{"date-parts":[[2018,5,21]],"date-time":"2018-05-21T04:07:30Z","timestamp":1526875650000},"page":"785","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Remotely Sensing the Biophysical Drivers of Sardinella aurita Variability in Ivorian Waters"],"prefix":"10.3390","volume":"10","author":[{"given":"Jean-Baptiste","family":"Kassi","sequence":"first","affiliation":[{"name":"Cursus Environnement Marin et Cotier, Centre Universitaire de Recherche et d\u2019Application en T\u00e9l\u00e9d\u00e9tection (CURAT), UFR STRM, BP 801 Abidjan 22, Cote d\u2019Ivoire"},{"name":"D\u00e9partement des G\u00e9osciences Marines, Universit\u00e9 F\u00e9lix Houphou\u00ebt-Boigny, UFR STRM, BP V34 Abidjan, Cote d\u2019Ivoire"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7584-2515","authenticated-orcid":false,"given":"Marie-Fanny","family":"Racault","sequence":"additional","affiliation":[{"name":"Plymouth Marine Laboratory (PML), Prospect Place, The Hoe, Plymouth PL1 3DH, UK"},{"name":"National Centre for Earth Observation (NCEO), PML, Plymouth PL1 3DH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brice A.","family":"Mobio","sequence":"additional","affiliation":[{"name":"Cursus Environnement Marin et Cotier, Centre Universitaire de Recherche et d\u2019Application en T\u00e9l\u00e9d\u00e9tection (CURAT), UFR STRM, BP 801 Abidjan 22, Cote d\u2019Ivoire"},{"name":"D\u00e9partement des G\u00e9osciences Marines, Universit\u00e9 F\u00e9lix Houphou\u00ebt-Boigny, UFR STRM, BP V34 Abidjan, Cote d\u2019Ivoire"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Trevor","family":"Platt","sequence":"additional","affiliation":[{"name":"Plymouth Marine Laboratory (PML), Prospect Place, The Hoe, Plymouth PL1 3DH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shubha","family":"Sathyendranath","sequence":"additional","affiliation":[{"name":"Plymouth Marine Laboratory (PML), Prospect Place, The Hoe, Plymouth PL1 3DH, UK"},{"name":"National Centre for Earth Observation (NCEO), PML, Plymouth PL1 3DH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6714-2180","authenticated-orcid":false,"given":"Dionysios E.","family":"Raitsos","sequence":"additional","affiliation":[{"name":"Plymouth Marine Laboratory (PML), Prospect Place, The Hoe, Plymouth PL1 3DH, UK"},{"name":"National Centre for Earth Observation (NCEO), PML, Plymouth PL1 3DH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kouadio","family":"Affian","sequence":"additional","affiliation":[{"name":"Cursus Environnement Marin et Cotier, Centre Universitaire de Recherche et d\u2019Application en T\u00e9l\u00e9d\u00e9tection (CURAT), UFR STRM, BP 801 Abidjan 22, Cote d\u2019Ivoire"},{"name":"D\u00e9partement des G\u00e9osciences Marines, Universit\u00e9 F\u00e9lix Houphou\u00ebt-Boigny, UFR STRM, BP V34 Abidjan, Cote d\u2019Ivoire"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,18]]},"reference":[{"key":"ref_1","unstructured":"Fr\u00e9on, P.
