Article
The recruitment of primary growth (PG) oocytes to the secondary growth (SG) phase within the ovulatory cycle, i.e. time interval between two sequential ovulation/spawning events, has rarely been examined in detail in a quantitative manner for batch spawning fishes with indeterminate fecundity. In the present study we analyzed the ovarian dynamics o...

The Macedonian shad, Alosa macedonica, is an endemic species of lake Volvi and is one of the few holobiotic alosine populations. Parameters of its reproductive biology, such as the spawning strategy and the fecundity type, remain unknown, and thus were defined in this study through its ovarian dynamics. A combination of histological and whole mount...

Lack of morphological features due to food processing is common in elasmobranchs. Such methods increase the chances of species substitution with cheaper alternatives or endangered species, leaving consumers unprotected from unfair or deceptive practices. DNA barcoding has become the most commonly applied approach for species identification, as it i...

The present paper reports the first well-documented record of a juvenile of the blackfish, Centrolophus niger (Gmelin, 1789) in Thermaikos Gulf and generally in Greek coastal waters. A single specimen of C. niger measuring 297 mm total length (226 mm SL) and weighing 280 g. was collected on June 4th 2018 using trammel nets at a depth of 35 m in The...
Article
Food authenticity has received an increasing focus due to high profile cases of substitution/mislabeling, with many investigations identifying sales of endangered or prohibited species. At the same time, the European Union (EU) has introduced one of the most progressive sets of legislation in order to promote traceability and protect consumers. Thi...
Conference Paper
Full-text available
Detection of fraudulent commercialisation of seafood products has been extensively reported. Although traditional methods of morphological identification offer a straightforward solution for recognizing fish species, it is not possible to use them on certain fish products such as fish fillets. Fortunately, DNA-based methods offer an alternative sol...
Conference Paper

In this collective article we discuss the relationships between the otolith measurements (weight, radius) and total length of Mullus surmuletus in the Aegean and Ionian Seas and of Pagellus erythrinus samples caught in the Southern Aegean Sea. In addition to the above mentioned studies, the abundance of the rare fish Echiodon dentatus in the Kyklad...
Conference Paper
According to the Greek Food & Safety legislation requirements, only the Mustelus spp. products should be sold as “galeos”. A DNA methodology based on the PCR amplification and sequencing analysis of two mitochondrial genes (16S rRNA and COI) was developed, for detection of mislabelled seafood products commercialized with the term “galeos”. A total...

The agujon needlefish Tylosurus acus imperialis appears in the Mediterranean Sea and for the last seven years large quantities have been caught in Thermaikos gulf (N. Aegean Sea) from mid-May to early September. This species is much larger than the garfish Belone belone, with an average length of 74.9 cm (±1.15) and average weight of 563.5 g (±33.7...
Conference Paper
Several studies have detected fraud in fish markets, mainly by substituting species with others of a different price or identity. Species identification cannot be properly controlled unless genetic markers are employed, especially when the commercial product is not the whole specimen. A simple PCR amplification of the nuclear 5S rDNA gene and/or th...

Mullets (grey mullets) are a family (Mugilidae) and order of ray-finned fish found in temperate and tropical waters worldwide. There are approximately 80 species of mullet; these fish have been considered an important food source in Mediterranean Europe since Roman times. This book provides a long overdue update on the biology and ecology of mullet...

Genetic and phenotypic characters were used to identify large-sized needlefish harvested during summer at a fishing ground in Thermaikos Gulf, North Aegean Sea. A single haplotype was found among five individuals, using a 558 bp nucleotide sequence of the 16S rDNA gene of mtDNA. Results of a BLAST engine showed a 99% percentage of maximum identity...

Increasing numbers of Tylosurus needlefishes together with common Belone needlefishes appeared in Thermaikos Gulf (North Aegean Sea, Greece) from 2012 to 2014, especially from May to August. The Tylosurus individuals were identified because of the absence of gill rakers and the presence of black thin lateral keel on caudal peduncle. From June 2013...

The thick lipped grey mullet (Chelon labrosus) is a widely distributed, euryhaline marine teleost species. Due to its benthic feeding behaviour on the lowest trophic level, it’s an important component in the flow of energy through ecosystem. The species considered as having an interesting aquaculture potential among others for its tasty flesh, its...
