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 ... -
EDITORIAL NOTE ON WEIGHT-LENGTH RELATIONS OF FISHES
(2011)Weight-length relations of fishes are useful for estimation of biomass from length observations, e. g., in fisheries or conservation research. Here we provide some guidance to authors of such papers, in order to facilitate ... -
Estimation and reconstruction of shore-based recreational angling fisheries catches in the Greek Seas (1950-2010)
(2013)The present work aims to estimate the shore-based recreational angling fisheries catches per species and Greek subarea that are not recorded by the official authorities in order to have a better picture of the total fish ... -
Fish market prices drive overfishing of the 'big ones'
(2014)The relationship between fish market price and body size has not been explored much in fisheries science. Here, the mean market prices and fish body size were collected in order to examine the hypothesis that large fish, ... -
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 ... -
Life-history characteristics of the endangered Aristotle's catfish (Silurus aristotelis Garman, 1890), Lake Pamvotis, north-western Greece
(2009)P>The life history characteristics of Aristotle's catfish, Silurus aristotelis (Agassiz 1856) were studied in Lake Pamvotis (northwestern Greece). Samples were collected on a monthly basis using gillnets, trammel-nets and ... -
Ranking and classification of fishing areas using fuzzy models and techniques
(2010)P>Fuzzy-logic-based methods and fuzzy logic formalism have been demonstrated as appropriate to address the uncertainty and subjectivity in complex environmental problems. This study investigates the use of three fuzzy logic ... -
Reproductive biology of the marbled goby, Pomatoschistus marmoratus (Pisces, Gobiidae), in a northern Aegean estuarine system (Greece)
(2009)The reproductive biology of the marbled goby, Pomatoschistus marmoratus (Risso, 1810), was studied in the Strymon River estuarine system (northern Greece) between September 1997 and August 1999. Samplings were conducted ... -
Shift in Trophic Level of Mediterranean Mariculture Species
(2014)The mean trophic level of the farmed fish species in the Mediterranean has been increasing. We examined the farming-up hypothesis (i.e., the increase in the production of high-trophic-level species) in the Mediterranean ... -
Spawning period of Mediterranean marine fishes
(2010)We collected all available information (i.e. international and local journals, conference proceedings, theses, technical reports) on the spawning season (n = 511 stocks, 168 species), gonadosomatic index (n = 237 stocks, ... -
Summer distribution of fish larvae in northern Aegean Sea
(2009)Larval fish and hydrographic data were collected in Kavala Gulf (northern Aegean Sea) across a fine scale grid of 17 stations in two surveys, carried out in the beginning of July 2002 and 2003. Despite the different taxonomic ... -
Summer fish larval assemblages and station groups in the northern Aegean Sea
(2011)Fish larvae were collected in two surveys, carried out at the beginning of July 2002 and 2003 in Kavala Gulf (northern Aegean Sea) aimed at studying ichthyoplankton species assemblages and station groupings. The similarity ... -
Validating annulus formation and examining the potential use of pectoral spines for age determination in Aristotle's catfish (Silurus aristotelis)
(2011)P>The potential use of pectoral fin spines for ageing purposes was examined in Aristotle's catfish (Silurus aristotelis) and validated for growth proportionality and growth mark periodicity. Monthly samples (n = 436, total ...
