“…This sector of the Mediterranean Sea supports one of the highest productive areas within the region [19,20], which, together with the complex seafloor heterogeneity and the geographical location of the Alboran basin, promotes a high diversity of habitats and species [21,22], including ones of commercial importance. The latter has allowed the development of an intensive fishing activity targeting demersal, small pelagic and benthic species [23][24][25][26], with potentially adverse effects on vegetated benthic assemblages [27,28].…”

Meadows of the seagrass Posidonia oceanica inhabit most infralittoral bottoms of the Mediterranean Sea and are considered one of the main climax stages of the infralittoral environment. This seagrass has its western distributional limit along the coast of the Alboran Sea. Taking into account the decline of P. oceanica meadows and the global scenario of ocean warming, it becomes essential to know the structure, temporal dynamics, sexual reproduction and conservation status of this seagrass, across its geographical distribution, including the distribution boundaries where the meadows withstand limiting environmental conditions. In the present work, we studied the structure, phenology and flowering events of four P. oceanica meadows located in the northwestern Alboran Sea (close to the Strait of Gibraltar). Results indicate a decreasing trend of patch size, bathymetric range and number of leaves per shoot towards the Strait (and the Atlantic Ocean), as well as an increasing trend of shoot density and leaf height. Phenological parameters of the northwestern Alboran Sea P. oceanica meadows presented temporal dynamics similar to meadows from other locations within the biogeographical distribution of this seagrass, with similar or even less annual variability in the former. Although most of the studied P. oceanica meadows seem to present a good health status (BiPo index ~0.6) with high shoot densities and some flowering events, some of them showed evidence of regression.

“…In the Mediterranean Sea, the Bay of Málaga (located in the central part of the north Alboran Sea), is the most important nursery site for the European sardine (Sardina pilchardus) and anchovy (Engraulis encrasicolus) (García et al 1988, García 2010, Giannoulaki et al 2013. The bay is an essential habitat for these SPF species as it fulfills the Bakun triad, a set of conditions needed for larvae survival (Agostini & Bakun 2002), including high abundances of phytoplankton and zooplankton (Mercado et al 2007, Yebra et al 2017.…”

Molecular techniques are offering new insights on the feeding strategy and diets of planktonic organisms such as the larvae of marine fish. We applied multiplex PCR to provide the first estimates of the diets of the larvae of European sardine (Sardina pichardus) in the Alboran Sea (SW Mediterranean), where this species represents an important fishery resource. The feasibility of this technique was tested in a 26-hour continuous survey of a shoal of larvae (mean±SD, 10.80±0.73 mm in standard length). Multiplex PCR was designed to detect the presence of five copepod species, a microplanktonic dinoflagellate (Gymnodinium) and the picoeukaryote algae family Prasinophyceae in larval guts. We simultaneously sampled sardine larvae and their potential prey (pico-to mesoplankton) and compared diel variability of the prey field and ingested items.Microplankton was dominated by flagellates and copepods represented the most abundant mesozooplankton, reaching peak abundance at night. Prey DNA was detected throughout the entire diel cycle, despite no visible prey in the guts of larvae collected at night. Sardine larvae preyed on early life stages of the most abundant copepod species (Oncaea waldemari, Paracalanus indicus and Temora stylifera), suggesting an opportunistic foraging behavior. The use of multiplex PCR allowed species-level identification of ingested nauplii and protists, which otherwise would remain unidentified.

The oceanography of the Alboran Sea (AS) has been the subject of intensive research for decades. Chief among the reasons for this interest is the variety of physical processes taking place in the basin, spanning from coastal upwelling, dynamic of density fronts, internal waves, and strong meso- and submesoscale turbulence. Historical fieldwork and an increasing number of numerical studies in recent years have led to a more complete—although more dispersed—description and knowledge of process dynamics in the AS and their role in shaping primary productivity and regional fisheries resources. In this review, we summarize and put together old and new research to get an updated picture of the AS circulation and its variability at different time scales, with an emphasis on physical–biological interactions. As part of the review, we identify gaps in our understanding regarding the physical drivers for seasonal and for rapid transitions between the most recurrent one-gyre and two-gyre modes of circulation of the AS. We also point at possible research strategies based on end-to-end regional biophysical modeling to gain new insights into past and present physical control on fisheries resources and for assessing plausible climate change impacts on the AS ecosystem.
