Historically, two angel shark species, common angel shark <italic>Squatina squatina</italic> and smoothback angel shark <italic>Squatina oculata</italic>, were common in the upper continental shelf of the eastern Adriatic Sea. Although both species are considered critically endangered in the Adriatic and the rest of the world, there are almost no data on the current status of populations, threat assessment and species-specific in-situ conservation. Common angel shark is still present in highly fragmented areas of the eastern Adriatic with extremely rare but consistent records, while smoothback angel shark is mostly considered regionally extinct in the Adriatic due to overfishing and overuse of non-selective fishing gear. There have been only 3 published records of common angel shark this century, the last two of which were reported by fishermen. This paper presents data on 34 new finds, including neonates, juveniles, subadults and adults recorded between January 2020 and August 2021 in the Zadar-Šibenik archipelago (central Adriatic) and one in Premantura (northern Adriatic). Two are original findings during the field expedition, 9 were reported directly by local fishermen, while 23 were reported through a detailed questionnaire. Additionally, plausible breeding and/or nursery grounds between Zadar and Šibenik are discussed with their importance for revitalization and long-term conservation in situ.

Along with growing consumer awareness about the impact of food on health, there is a trend towards increasing fresh fish consumption. At the same time, the demand for organic food is increasing in the modern market. Although fruits, vegetables and nuts have the biggest share in the organic food market in Europe, the aquaculture production of organic fish is also growing. Therefore, the main aim of this study is to explore the knowledge and perception of Croatian consumers about fresh fish from organic farming. An online and face-to-face survey was conducted on a sample of 303 respondents. Data analysis (univariate and bivariate) was performed using SPSS Statistics for Windows. Most consumers have medium and low subjective knowledge about fresh fish from organic farming, and objective knowledge about fresh fish from organic farming is low. Only half of the consumers are aware that they can buy fresh fish from organic farming in the domestic market. Half of the consumers have already consumed fresh organic fish, and half are willing to pay a higher price for fresh fish from organic farming. Compared to fresh fish from conventional farming, respondents consider fresh organic fish to be healthier, tastier and to have less fat, but also more expensive and less available.

Evidence from the last two centuries has identified changes in the biodiversity of the Mediterranean basin triggered by the arrival of new species. Compared to the central and northern areas, the southern part of the Adriatic Sea, specifically the Albanian coast, has been less studied. The aim of this study is to evaluate the prevalence of new/non-native fish species on the north Albanian coast in order to provide the first data on their presence. Data collection was carried out from March to August 2019 using LEK (Local Ecological Knowledge) protocol in five different locations along the northern part of the Albanian coast. The research followed a predefined methodology previously successfully applied in different countries of the Mediterranean basin by using a semi-structured questionnaire. During this study, 9 new and non-native species were recognized by the fishers, while only 5 of them have shown an evident abundance increase based on their respective catches in recent years. Results suggest that some of the analyzed species, such as blue crab <italic>Callinectes sapidus</italic> and bluefish <italic>Pomatomus saltatrix,</italic> represent important members of the fish fauna in north Albania coastal waters (including the lagoons). Future studies regarding the assessment of their impact and management strategies are highly recommended.

Tracking Changes in Fish Diversity in the South-Eastern Adriatic Sea (Albania) Based on Local Ecological Knowledge

The lack of reliable fisheries statistics hampers full assessment of the status of marine resources. Central to this problem are data-poor fisheries such as the Albanian seas and in particular the SSF sector. The present study aims to portray the small-scale fishery of south Albanian waters based on daily onboard monitoring of fisheries species catches during a two-year period (2016-2018). Results revealed a total of 6 and 11 fishing métiers for the nets and longlines, respectively. The most important target species for nets in terms of catches were <italic>Merluccius merluccius</italic>, <italic>Mullus surmuletus</italic>, <italic>Pagellus erythrinus</italic>, <italic>Sepia officinalis</italic> and <italic>Solea vulgaris</italic>. Longline fisheries were categorized into two distinct fishing métiers, one targeting the large pelagics <italic>Thunnus thynnus</italic> and <italic>Xiphias gladius,</italic> and the other targeting a wide range of Sparidae species and <italic>Epinephelus marginatus</italic>. The data and analysis presented here aim to reduce the current lack of quantitative data on a fisheries data-limited case such as the Albanian small-scale fishery and to provide information for developing monitoring for this fishery.

Underwater visual census (UVC) is a commonly used approach for assessing fish density and biomass. Iskenderun Bay, comprising the Samandağ coast in Turkey, is the most important introduction pathway of alien species in the northeastern Mediterranean. In this study, the density, abundance, distribution and interaction of invasive lionfish or devil firefish <italic>Pterois miles</italic> were assessed using the UVC method on the Samandağ coast. The total transect area monitored on the Samandağ coast was 4.500 m2. Species richness, Shannon’s diversity index and rate of biomass were 25, 1.81 and 73.5 m2, respectively. Reduced diversity was observed with increasing depths. The sandy seafloor was a limiting factor for lionfish distribution. There was a significant positive correlation between lionfish total density and both the Shannon diversity index (r = 0.99, P&lt;0.001) and Shannon evenness index (r = 0.99, P&lt;0.05). A high number of significant positive correlations (P&lt;0.05) were detected between the occurrence of lionfish and the occurrence of both the native species and other alien species. The first stock assessment study of lionfish by the UVC method in Turkish marine waters revealed that native species are under very high pressure from lionfish species, especially Chromis, Sparids and Wrasses, indicating negative effects of lionfish on regional native biodiversity.
