Population genetic analysis of variation at five neutral microsatellite loci for Mediterranean mussels (Mytilus galloprovincialis) from 18 sites along the eastern Adriatic Sea revealed little or no spatial variation. In contrast, seascape genetics analysis revealed a pronounced locus-specific gradient in allelic and genotypic frequencies across the...

In Albania, the most produced species by the aquaculture sectors are represented (at a decreasing order) by gilthead seabream, European seabass, rainbow trout, carp species and Mediterranean mussels. The production of gilthead seabream and European seabass is realized by using the marine cage production systems along the south Adriatic and Ionian c...

Biodiversity is the measure of the variation of lifeforms in a given ecological system. Biodiversity provides ecosystems with the robustness, stability, and resilience that sustains them. This is ultimately essential for our survival because we depend on the services that natural ecosystems provide (food, fresh water, air, climate, and medicine). D...

Fresh water ecosystems in the Balkan region are well recognized by high level of endemism and therefore could be very sensitive to the negative impact of invasive fish species. These impacts are due to interaction among native and non-native fauna. Generally, the most obvious and common ones are competition for food and space resources as well as t...

Pumpkinseed fish is considered to be highly invasive; it has demonstrated great variability in its environmental biology in response to environmental conditions, since its first appearance in the European waters this species has established populations in at least 28 European countries. In Albania, pumpkinseed, was introduced in 1994, even though t...

Climate change has triggered heterogenous pattern of changes in abundance, survival, growth, reproduction phelogeny and distribution of different aquatic communities. The Mediterranean Sea has been identified as one of the most vulnerable regions, and it is expected to become warmer and drier with an increase in inter-annual variability due to extr...

One shark was landed at the Naval Base Pasha Liman, Bay of Vlore, Albania, the Adriatic Sea. Photographic records only enabled the specimen to be placed in family Odontaspididae or Carchariidae. Later examination of the preserved head, dry jaw and dentition identified the specimen as Odontaspis ferox . This is a rare record and the northernmost Med...

Metallothioneins (MTs) are low-molecular weight sulfur-rich proteins, widely distributed in nature. They play a homeostatic role in the control and detoxification of metal ions. Previous studies indicated that MTs also have the capacity to scavenge reactive oxygen species. This study aimed to investigate the evolution of the protein in the notothen...

The present study uses fisher knowledge to outline the basic socioeconomic framework of Albanian lagoon fisheries based on on-the-spot interviews conducted with fishers operating in the most important Albanian lagoons. The results indicated that Albanian lagoon fisheries were family-based, with spatial differences observed in vessels from the north...
Conference Paper
Mediterranean mussel (M. galloprovincialis) is the most common bivalve species in the Mediterranean sea, able to survive across broad ranges of temperature and salinity. Albania is the 4th largest European producer of M. galloprovincialis, after Italy, Greece and France and there is an increasing trend. However, Mediterranean mussels is vehicles in...

Fisheries constitute a major threat to marine mammals globally. To evaluate the impact of small-scale fisheries (SSF) on regional under-studied marine mammal populations, we tested a novel and cost-effective approach at three data-limited locations of the central and eastern Mediterranean Sea. Using off-the-shelf GPS loggers to track SSF activities...

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 cat...

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-...

Elasmobranchs, mainly represented by sharks and rays, account for 0.8% of bottom trawl total landings in the South Adriatic Sea. The thornback ray (Raja clavata, Linnaeus, 1758) represents one of the most important species in terms of landing in the Mediterranean basin. Several studies have shown that k-selected species, like elasmobranchs, with lo...

Introduction The delineation of critical habitats forms an important step in the implementation of marine protected areas (MPAs). Whilst MPAs have been shown to be an effective conservation strategy, they cover just 5% of the Adriatic, with no MPAs in Montenegro and a single MPA, Karaburun Sazani, in Albania. The Adriatic Sea has been identified a...

Peroxiredoxins are antioxidant enzymes that use redox active Cys residues to reduce H2O2 and various organic hydroperoxides to less reactive products, and thereby protect cells against oxidative stress. In yeasts and mammals, the Prx1 proteins are sensitive to hyperoxidation and consequent loss of their peroxidase activity whereas in most bacteria...
