“…Red mullet largely preyed on copepods, amphipods, decapods and polychaete larvae. This result is in accordance with data previously reported from the Adriatic (Vrgoč et al, 2004) and Mediterranean populations of this species (Vassilopoulou and Papaconstantinou, 1993;Bautista-Vega et al, 2008;Chérif et al, 2011;Esposito et al, 2014;Boudraa et al, 2018;Onay and Dalgic, 2019). Our data on the diet of European hake were qualitatively similar to that reported in previous studies from both the Adriatic (Vrgoč et al, 2004;Riccioni et al, 2018) and Mediterranean seas (Bozzano et al, 2005;Carpentieri et al, 2005;Philips, 2012;Modica et al, 2015;Carrozzi et al, 2019).…”

We examined how the trophic ecology of nine economically important marine taxa varied across three distinct areas of the Adriatic Sea. These taxa included three species of demersal fishes (European hake Merluccius merluccius, red mullet Mullus barbatus, black-bellied angler Lophius budegassa) and two species of decapod crustaceans (Norway lobster Nephrops norvegicus, deep-water rose shrimp Parapenaeus longirostris) and four species of pelagic fishes (sardine Sardina pilchardus, anchovy Engraulis encrasicolus, Mediterranean horse mackerel Trachurus mediterraneus, Atlantic horse mackerel Trachurus trachurus). We used two complementary methods that differed in their temporal context to examine and compare diet. Stomach contents analysis was used to describe the short term diet while stable isotope analysis was used compare long-term assimilated diet. Results showed that although there were spatial differences in what each species consumed, and in their trophic and isotopic niches, each species fed at similar trophic position across locations, indicating similar ecological function. Comparisons of biomass-weighted trophic position (δ15N) and consumer body size (log2 mass) showed evidence for a common isotopic size spectrum across areas, indicating the existence of a size-structured food web. In turn this allowed us to provide a first estimate of the predator–prey body mass ratio (PPMR) for this area (655:1). Results obtained within this study, in future, could be used for ecological modeling and improved long-term management of the Adriatic Sea’s marine resources.

“…Although obtained from values integrated within the upper water column (0-30 meters depth), our simulations show that the inclusion of a proxy for food concentration is important to assess the distributional range of SHEVs. While the eight SHEVs we modelled are carnivores with trophic levels ranging from 3.2 (surmullet 33 ) to 4.4 (European hake 34 ), the indirect relationship between primary production and sh stocks has already been thoroughly documented 35 . The relationship between primary production and upper trophic levels is also strongly in uenced by factors related to the trophic processes that de ne the movement of endosomatic energy along the food chain, but also other physical factors such as chlorophyll a 36 .…”

Fisheries and aquaculture are facing many challenges worldwide, especially adaptation to climate change. Investigating future distributional changes of largely harvested species has become an extensive research topic, aiming at providing realistic ecological scenarios on which to build management measures, to help fisheries and aquaculture adapt to future climate-driven changes. Here, we use an ensemble modelling approach to estimate the contemporary and future distributional range of eight fish Species of High Economic Value (SHEV) in the Mediterranean Sea. We identify a cardinal influence of (i) temperature on SHEVs distributions, all being shaped by yearly mean and seasonality in sea bottom temperature, and (ii) the primary production. By assessing the effects of changes in future climate conditions under three Representative Concentration Pathway (RCP2.6, RCP4.5 and RCP8.5) scenarios over three periods of the 21st century, we project a contraction of the distributional range of the eight SHEVs in the Mediterranean Sea, with a general biogeographical displacement towards the North European coasts. This will help anticipating changes in future catch potential in a warmer world, which is expected to have substantial economic consequences for Mediterranean fisheries.

“…The host species T. draco, P. acarne, and M. barbatus were most infected with parasitic nematode larvae. Arthropoda, Mollusca, Nemathelminth, Teleostei species are potential prey of these fish species (Morte et al 1999, Fehri-Bedoui et al 2009, Chérif et al 2011.…”

Numerous marine fishes from the Algerian coast were examined for nematode parasites. Our study revealed five species of nematodes that were identified according to morphological characteristics: Anisakis simplex, Hysterothylacium aduncum, Hysterothylacium reliquens, Hysterothylacium fabri, Dichelyne pleuronectidis. D. pleuronectidis was newly collected from the study region. Four new host species were recorded for A. simplex, six for H. aduncum, and three for H. fabri. The infection rates observed were higher for Hysterothylacium and Dichelyne than Anisakis. The highest infection rate by Nematoda parasites were recorded for Trachinus draco L., Pagellus acarne (Risso) and Mullus barbatus L. (P = 100%, P = 53.33%, P = 42.5%), respectively. Nematoda larvae were found in body cavity and musculature. Histological changes associated with nematode musculature infestation revealed myodegeneration of fibers with a loss of striated texture and skin damage.
