Acute stress response of European sea bass Dicentrarchus labrax under blue and white light
(2012)Recent data suggest that specific light wavelength can alleviate fish acute stress response by counteracting or reducing the stress-induced cortisol increase. The European sea bass Dicentrarchus labrax, widely reared in ... -
Aegean Bath Sponges: Historical Data and Current Status
(2011)This study attempts to evaluate the status of the populations of bath sponges (species of the genera Spongia and Hippospongia) in the Aegean, combining historical sources dated before a series of disease outbreaks that ... -
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 ... -
Analysing consumers' perceived differences in wild and farmed fish
(2015)Purpose - The purpose of this paper is to investigate consumers' attitudes and behaviours towards wild and farmed fish, in order to identify possible distinct consumer groups, and to examine potential linkages between ... -
Analysing managerial perceptions towards performance determinants in the fishery sector
(2011)This paper attempts to empirically investigate potentially significant differences in perceptions regarding firm performance in the fishery sector. The primary data were gathered from several fisheries through a survey. A ... -
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 ... -
Assessing the state of Greek marine fisheries resources
(2013)Annual fish landings for the Greek seas were analysed for the period 19822007 and classified into exploitation categories based on a catch-based stock classification method. In 2007, about 65% of the Greek stock were ... -
Assessment of dietary supplementation with carvacrol or thymol containing feed additives on performance, intestinal microbiota and antioxidant status of rainbow trout (Oncorhynchus mykiss)
(2012)The manipulation and control of fish health and production by natural substances has been identified as an important area for future developments in aquaculture. A study was conducted to investigate the effect of two ... -
A brief exposure to low pH prior to refrigerated storage reduces the motility and viability of goldfish sperm (Carassius auratus, Linnaeus, 1758)
(2015)Optimal conditions of short-term storage of fish sperm are important for successful artificial reproduction protocols or incubation of sperm in a cryoprotecting medium for successful sperm cryopreservation. The influence ... -
A case of high mortality due to heavy infestation of Ceratomyxa diplodae in sharpsnout sea bream (Diplodus puntazzo) treated with reproductive steroids
(2007)A case of 100% mortality in cultured sharpsnout sea bream (Diplodus puntazzo) caused by Ceratomyxa diplodae after sustained steroid treatment for induction of sex inversion is described. The pathology caused by the parasite ... -
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 ... -
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 ... -
Cryptosporidium in fish: Implications for aquaculture and beyond
(2021)Aquaculture industries are expanding worldwide and control of Cryptosporidium is of great importance. Cryptosporidiosis is a serious waterborne/foodborne disease, responsible for infectious outbreaks globally. Current ... -
The culture potential of Paracentrotus lividus (Lamarck 1816) in Greece: a preliminary report
(2009)Two hundred and forty adult and sub-adult Paracentrotus lividus were divided into two major groups (adults, sub-adults) based on their diameter differences (above or below 40 mm) and allocated to baskets suspended from the ... -
THE DETERMINANTS OF CONSUMPTION FOR ORGANIC AQUACULTURE PRODUCTS-EVIDENCE FROM GREECE
(2014)This study investigates Greek consumers' behavior towards organic aquaculture products, identifying possible distinct consumer groups and examining possible linkages between consumer characteristics and marketing aspects ... -
The development of size variation in Dover sole, Solea solea and turbot, Scophthalmus maximus: genetic variability between different geographical and among year class farmed strains
(2013)Growth and variation in size of turbot and sole larvae originating from different genetic sources were compared at different stocking densities, including genetically based information that might lead to a better knowledge ... -
Digestibility of nutrients and energy in diets for the African catfish Clarias gariepinus (Burchell 1822)
(2004)A purified diet, the raw material zein, and two diets composed of complex foodstuffs (fishmeal, soy, wheat) were tested for eight months in the African catfish Clarias gariepinus (Burchell 1822) to determine the in vivo ... -
Early diagnosis of enteromyxosis in intensively reared sharpsnout seabream, Diplodus puntazzo
(2014)Myxozoans are metazoan parasites which are highly pathogenic in commercially important fish, particularly in aquaculture. Enteromyxosis is an economically significant disease caused by the myxosporean parasite Enteromyxum ...
