Understanding of cetaceans’ trophic role and the quantification their impacts on food web is a critical task, especially when data prey are linked to deep-sea ecosystems, which often exposed excessive exploitation fishery resources due poor management. This aspect represents one major issues in marine resource management, trade-offs needed simultaneously support conservation cetaceans irreplaceable ecological role, together with sustainable fishing yield. In that regard, models can represent...
Abstract Macro-benthic communities on the shallowest soft bottoms are impacted by hydraulic dredgers used for harvesting of striped venus clam ( Chamelea gallina ). Changes in macro-benthic assemblages were analysed across four areas Southern Adriatic Sea (Central Mediterranean Sea) during winter and summer 2022 (low high fishing pressures, respectively). Two sampling surveys carried out collecting abundance data (N/100m 2 ) 69 species. Diversity indices (Shannon–Weiner Equitability)...
A modelling approach applied to the study of ecosystems from a management and conservation point view allows their complexity be investigated represents tool for meeting sustainability goals, part 2030 Agenda Sustainable Development. Tying into Development Goals (SDGs) 13 14, human activities fisheries climate change represent two pivotal drivers marine environment, acting on keystone predators, such as odontocetes. calibrated time-dynamic model (Ecopath with Ecosim) was developed...
Stranding data provide fundamental information on biometric traits of cetaceans useful to increase knowledge ecological and their consumption patterns. In this study, the length weight (L-W) relationships through power regression model (W=a×Lb) were calculated for three dolphin species (the striped dolphin, common bottlenose Risso's dolphin) in several Mediterranean subregions at scale entire basin. Length (L) (W) collected from stranding records during period 1983 2021 acquired databases...
The assessment of the spatial overlap between eligible cetacean conservation areas (CCAs) and fishing grounds could be a strategic element in implementation effective measures pelagic offshore areas. A multi-species bio-economic modelling approach has been applied to estimate traits CCAs Northern Ionian Sea (NIS, Central Mediterranean Sea) 10-800 m depth, adopting Spatial MAnagement demersal Resources for Trawl fisheries model (SMART). Four possible were defined according distribution...
Abstract Cetaceans are considered bioindicators of the health state marine ecosystems owing to their wide distribution across different aquatic in world and significant top‐down control role food chain, despite low biomass. At same time, effective management wild cetacean populations severely affected by human pressure requires extensive knowledge on species distribution, habitat use, associated threats. In this context, defining factors that directly influence local occurrence cetaceans is...
The structure of benthic assemblages impacted by hydraulic dredges in Margherita, Barletta, Lesina, and Varano areas (Southern Adriatic Sea) have been explored through a multivariate analysis conducted on abundance data (N/100 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) collected during two summer surveys, 2018 2019. Overall, 134 hauls were performed approximately equally split over the years. differences composition investigated...
This study is the first attempt at applying Ecosim modelling approach to explore temporal effects of fishing effort (FE) changes on odontocetes in food web Gulf Taranto.

Stranding records regarding the striped dolphin (Stenella coeruleoalba) were collected from Italian Network database (CIBRA), online open sources databases and scientific literature in a period ranging 1983 to 2021. Recordings classified into Mediterranean geographic areas according International Hydrographic Organization. A total of 1500 stranded individuals considered analysis. The showed highest median length 188 cm (IR=38.5, n=95) Adriatic Sea. value weight was recorded Western Sea, with...
The catch efficiency of LED lamps in the purse seine fishery as well their performances from environmental sustainability point view has been tested Adriatic Sea. In September and October 2020, a white light (LWH) configuration blue (LBLU) were alongside incandescent lamp (INC) by means 20 experimental trials characterized 44 comparisons among lighting systems. Catches composed for over 98% total biomass anchovies (Engraulis encrasicolus) compared through Catch Per Unit Effort (CPUE) terms...
The Mediterranean population of monk seal (Monachus monachus) is reported as "Critically endangered" by IUCN Red List and its spatial distribution seems to be fragmented in colonies, mainly found around the Ionian Aegean islands.Monk seals are proved highly affected human pressure such boat traffic fishery. Previous studies highlighted occurrence net depredation interactions with artisanal small-scale fisheries. Accordingly, a source concern little quantitative information on various aspects...
The striped venus clam (Chamelea gallina Linnaeus, 1758) is one of the most important commercially valuable bivalves distributed in Italian sandy soft bottoms Adriatic Sea (Central Mediterranean Sea). impacts hydraulic dredge used harvesting this bivalve have been widely investigated area, while poor data are available on relationships between juveniles' recruitment and water circulation. This preliminary study explores dynamics C. populations Northern Gargano Area during period 2018-2019,...
