Article
Full-text available
Due to the fast growth rate, the short life cycle, the high market price and the high food conversion efficiency, O. vulgaris is considered as a good candidate for aquaculture. One of the prerequisites for the successful integration of new species, such as octopi, into industrial-scale production, is the knowledge of the pathological conditions tha...

Viral nervous necrosis (VNN) is an infectious disease caused by the red-spotted grouper nervous necrosis virus (RGNNV) in European sea bass and is considered a serious concern for the aquaculture industry with fry and juveniles being highly susceptible. To understand the genetic basis for resistance against VNN, a survival phenotype through the cha...

Biogenic films are very thin surface oils, frequently observed near aquaculture farms, that affect the roughness and the optical properties of the sea surface, making them visible in SAR and multispectral images. The purpose of this study is to investigate the potential of satellite SAR and multispectral sensors in the detection of biogenic oil fil...

A case of epithelial tissue tumors on the body of two adult Brown meagres (Sciaena umbra Linnaeus, 1758) is reported. Brown Meagre population of 20.000 was imported to sea cages on September of 2003 at 3g, to check the potential use of this species as a new candidate in Mediterranean aquaculture. The population had been kept for 8 years to serve as...

This study presents the length-weight relationships (LWR) for 12 commercial fish species from coastal waters off South Corfu Island (N. Ionian Sea, Greece). All fish originated from the catches made by a single artisanal fisherman during April – September 2009. Multiple types of predominantly static fishing gear were used, mainly gillnets (mesh siz...
Article

The cryptogenic parasite Haplosporidium pinnae has caused mass mortality of the protected endemic Mediterranean bivalve Pinna nobilis in the western Mediterranean, since the autumn of 2016. Herein, we confirm the spread of the parasite in the eastern Mediterranean, and report a mass mortality event, with > 93% average mortalities, in the coastal wa...
Conference Paper
Full-text available
The present study presents a transdisciplinary effort in searching, selecting, developing and implementing indicators for the assessment of ecosystem services (ESs) in the coastal zone. Despite the various classifications developed in recent years, the majority of the relevant studies result in qualitative evaluations of the main ESs of the coastal...
Article
Full-text available
Parasites and associated pathology of wild caught Serranidae in the Aegean Sea were investigated in order to contribute to the scientific information regarding pathological findings of these fish. Various lesions and parasitic organisms, such as Digenean parasites, cysts and metacercaria, Cestode cysts and a nematode, were observed in the gills / p...
Article
Full-text available
The specific humoral immune response of sea bream, Sparus aurata (L.), against Vibrio anguillarum O1 and Photobacterium damselae subsp. piscicida (Phdp) after immunization with commercial and experimental bacterins was analysed quantitatively and qualitatively. Specific anti- V. anguillarum O1 and anti-Phdp levels provoked by the adjuvanted commerc...
Article
The parasitic fauna of the small-spotted catshark, Scyliorhinus canicula in the north-eastern Aegean Sea was investigated. Twenty-one out of the 52 (prevalence 40.4%) specimens collected were found infected with parasites; an arthropod and two nematode genera. Seven specimens (prevalence 13.5%) were infected by a Neoalbionella sp. copepod. Ten and...
Article
Lagocephalus sceleratus, is a Lessepsian invasive fish species introduced into the Mediterranean Sea through the Suez Canal. This study investigated it as host of parasites. Out of 41 individuals caught from northern and southern locations of the eastern Aegean Sea, nine were found to host parasites. Gnathia sp. praniza larva, an ectoparasite, was...
Article
The long term efficacy of different bivalent commercial vaccine formulations against Vibriosis and Photobacteriosis in sea bass (Dicentrarchus labrax, L. 1758) was investigated. Duplicate whole cages in the field were intraperitoneally vaccinated with either an adjuvanted (AJ) or an aqueous (AV) commercial vaccine or with sterile 2% NaCl. All group...
Presentation
Full-text available
Groups of sea bass were immunized with adjuvanted and aqueous commercial vaccines (Vibrio spp. & Photobacterium damselae subsp. piscicida) and experimental formulations (only Ph. damselae subsp. piscicida) in order to measure specific IgM levels against either of the bacterial pathogens. The commercial adjuvanted vaccine caused the production of th...
Technical Report
Full-text available
This study contributes to a better understanding of the effects of small scale artisanal fisheries on fish stock status and overall marine biodiversity, both within the limits of the MPA of NMPZ, as well as in the North and Eastern coasts of Zakynthos Island. It also provides insights regarding the effectiveness of management measures, fishermen at...
