“…The present study confirmed the results of ERZINI et al (1996b). In addition, the same is also generally true for fish caught in the Cyclades with hooks having similar hook sizes as in the present study (STERGIOU et al, 2002). The different ecological indices gave conflicting results, with the mean number Medit.…”

“…All the above-mentioned analyses, which have been successfully applied to similar experimental fisheries data from the Cyclades and the Algarve (e.g. STERGIOU et al, 2002;, were carried out using the PRIMER algorithms (CARR, 1997).…”

“…Several comparative fishing studies have been carried out in a number of fisheries, but in most cases the studies have focused on one or two species (ENGAS et al, 1993;ELLIOTT & BEAMESDERFER, 1990;NEDREAAS et al, 1993;ROLLEFSEN, 1953;RUSSELL et al, 1988;YANG & GONG, 1988) with a few examples of a multi-species assemblage (STERGIOU et al, 1996;2002;ERZINI et al 1996b). ERZINI et al (1996b) compared small hook Medit.…”

Parallel fishing trials with 0.30 mm diameter monofilament gill nets and longlines using small hooks were carried out in the Algarve (southern Portugal) over a one-year period, 1997-1998, with the objective of comparing species composition, catch rates, discards and size ranges. Four hook sizes of 'Mustad' brand, round bent, flatted sea hooks (numbers 15, 13, 12 and 11) and four mesh sizes of 25, 30, 35 and 40 mm (nominal bar length) of gill nets were used in the trials. Overall, 84 species were caught, with gill nets taking 71 species and longlines 54 species and with 41 species caught by both gears. The amount of discarding was higher for gill nets than for longlines. The catch species composition differed between the two gears, with the commercially valuable sea breams dominating the longline catches whereas small pelagics were relatively more important in the gill nets. Multivariate analysis showed a clear separation between the different sizes of the two gears both in terms of numbers and weights per species. Algarve gill netters and longliners fish the same species assemblage on the same fishing grounds, but have clearly different impacts in terms of catch species composition, catch rates and sizes. This information will be useful for the improved management of these small-scale, multi-species, multi-gear fisheries, where different gears compete for scarce resources. In particular this study provides a basis for a more rational allocation of licenses and control of fishing effort.

“…The Mediterranean parrotfish (Sparisoma cretense L. 1758) is more common in the south and eastern parts of the Mediterranean Sea and its typical distribution range has been historically dictated by the February 15°C surface isotherm barrier. In Greece, it is incidentally caught in rocky shores up to 50 m depth mainly in the Dodecanese (Petrakis & Papaconstantinou, 1990;Kalogirou et al, 2010;Kalogirou et al, 2012), in the Kyklades islands (Stergiou et al, 2002) and in Kriti (Katsanevakis & Thessalou-Legaki, 2009). Up to now there has been no record of it from the Ionian Sea.…”

“…Univariate and multivariate analyses of the catch composition were made following the approaches of Stergiou and Pollard (1994), Stergiou et al (2002), Labropoulou and Papaconstantinou (2004), and Stergiou et al (2006). Clustering (average groups) was based on the Bray-Curtis similarity index (Field et al, 1982) applied to overall abundance and biomass data taking into account the 15 combinations of target species, year and area.…”
