Allozymic variation in Northeast Atlantic and Mediterranean populations of Norway lobster, Nephrops norvegicus
(2006)Allozyme starch gel electrophoresis was used to investigate the genetic structure of Nephrops norvegicus populations in an extended sampling scheme. Nine Populations from the North Sea and Aegean Sea were sampled and ... -
Antibacterial drugs in products originating from aquaculture: assessing the risks to public welfare
(2010)As aquaculture expands to meet human demand and compensate for pessimistic forecasts of fisheries catches, use of antibacterial agents to combat or forestall bacterial diseases is still a necessity, although effective ... -
Biodiversity of Cold Seep Ecosystems Along the European Margins
(2009)During the European Commission's Framework Six Programme, HERMES, we investigated three main areas along the European margin, each characterized by the presence of seep-related structures exhibiting different intensity of ... -
Census of biodiversity in marine caves of the eastern Mediterranean Sea
(2015)Scientific information on the biodiversity of marine caves in the eastern Mediterranean is limited, especially when considering the extensively studied caves of the north-western and central Mediterranean. Aiming to enhance ... -
Circulation in the Cretan Sea and adjacent regions in late winter 1994
(1997)This paper presents the qualitative circulation patterns of the ''upper'' and ''deeper'' layers in the Cretan Sea and its environs in late winter 1994. The qualitative aspects of the flow field were determined primarily ... -
Conservation aspects of natural populations and captive-bred stocks of turbot (Scophthalmus maximus) and Dover sole (Solea solea) using estimates of genetic diversity
(2007)Population genetic analyses have been highly successful in predicting inter- and intraspecific evolutionary relationships, levels of gene flow, genetic divergence, and effective population sizes. Parameters estimated are ... -
Cotton yield estimation based on NOAA/AVHRR produced NDVI
(2001)The high temporal resolution of the NOAA/AVHRR satellite data can provide an efficient and consistent way for biomass and yield monitoring and assessment. The reflected radiation provides an indication of the type and ... -
Ecosystem modeling: Towards the development of a management tool for a marine coastal system Part I: General circulation, hydrological and dynamical structure
(2012)The semi-enclosed environment of Pagasitikos Gulf was the object of a holistic study during 1998-1999 following the appearance of mucilaginous events during summer. A major part of the INSEA project was the development and ... -
Ecosystem modelling: Towards the development of a management tool for a marine coastal system part-II, ecosystem processes and biogeochemical fluxes
(2012)Pagasitikos gulf is a semi-enclosed basin highly influenced both by anthropogenic activities (inflow of nutrients at the north and west parts) as well as by water exchange between the gulf and the Aegean Sea at its south ... -
Fishing down, fishing through and fishing up: fundamental process versus technical details
(2011)Fishing through, fishing up (i.e. the observation that mean trophic levels [MTLs] of catches are increasing with time) and the question of agreement between MTL from catches and surveys have been used to question fishing ... -
Hydrography and circulation south of Cyprus in late summer 1995 and in spring 1996
(1998)The hydrodynamical characteristics of the area south of Cyprus in the Levantine Sea were examined in late summer 1995 and in spring 1996. Analysis of the CTD data collected, provided a new dynamic picture of the Cyprus ... -
IMAS-Fish: Integrated Management System to support the sustainability of Greek Fishery resources. A multidisciplinary web-based database management system: implementation, capabilities, utilization and future prospects for fisheries stakeholders
(2013)This article describes in detail the "IMAS-Fish" web-based tool implementation technicalities and provides examples on how it can be used for scientific and management purposes, setting new standards in fishery science. ... -
Loss of genetic variation in Greek hatchery populations of the European sea bass (Dicentrarchus labrax L.) as revealed by microsatellite DNA analysis
(2015)Genetic variation in four reared stocks of European sea bass Dicentrarchus labrax L., originating from Greek commercial farms, was assessed using five polymorphic microsatellite markers and was compared with that of three ... -
Ornamental fish in pet stores in Greece: a threat to biodiversity?
(2014)The aquarium trade has been recognized as an important pathway for the introduction of invasive species around the world. This study investigates the availability of ornamental fish species in ten large-size, centrally ... -
Polyphasic evaluation of Aphanizomenon issatschenkoi and Raphidiopsis mediterranea in a Mediterranean lake
(2010)Aphanizomenon issatschenkoi and Raphidiopsis mediterranea were studied in the Mediterranean Lake Doirani during a cyanobacterial bloom (August-October 2004). Aphanizomenon issatschenkoi was clearly morphologically distinct ... -
Population structure of Dover sole Solea solea: RAPD and allozyme data indicate divergence in European stocks
(2003)Randomly amplified polymorphic DNA (PCR-RAPD) analysis was used to estimate genetic variation within and between 6 Northeast Atlantic populations of Dover sole Solea solea (L.). A total of 16 fish were randomly selected ... -
Predicting demersal fish species distributions in the Mediterranean Sea using artificial neural networks
(2003)Predicting the occurrence of economically important demersal fish in a multispecies marine environment can be of considerable value to fisheries management and protection of biodiversity. Here, 2 predictive modelling ... -
Rainfall-frequency mapping for Greece
(2001)For the design of hydrotechnical projects in ungauged watersheds, the flood flow is estimated by various methods, which demand the estimation of rainfall of particular critical duration and return period. For medium-sized ... -
