“…Meanwhile the distribution of fishes in the estuarine area during the closed period was more evenly distributed than during the open period because the estuarine/marine species dispersed over the whole estuarine sampling area and there were less freshwater immigrants. Duldic et al (1997) reported that estuarine areas usually support low trophic level species with high ecological efficiency and productivity, and this was true in the present study as small-sized phytoplankton feeders, such as E. devisi, Leiognathus spp. and A. gymnocephalus, were major contributors to the %IRI in the estuary.…”

Following the construction of an anti-salt intrusion dam in Pak Panang River, Thailand, changes in the environmental conditions and fish assemblages were monitored both in the estuary and in the river. The present study was conducted during two different phases: when the sluices were open; and when they were closed. Salinity in the estuary declined (P < 0.001), but increased in the river during the open phase (P = 0.002). In the river, the pH increased (P < 0.001) during the closed phase, but was relatively constant in the estuary. No differences were found for water temperatures, chlorophyll a and abundance of phytoplankton. During the closed phase, the abundance of zooplankton was higher in the estuary, but the abundance of benthos in the river declined. Ninety-four fish species were collected. Species richness and the diversity index did not differ in the estuary, but were significantly different in the river; abundance was higher during the open phase. Fish moved between the two systems during the open phase and changes in fish assemblages correlated with salinity gradients and food sources. Sluice regulation to allow fish to move between the river and the estuary is recommended.

“…Several studies in the Mediterranean and European Atlantic archipelagos analysed relationships between both settlers and recruits and their habitat (e.g. Biagi et al, 1998;Bodilis et al, 2003;Dulčić et al, 1997;Francour & Le Diréach, 1994;García-Rubies & Macpherson, 1995;Harmelin-Vivien et al, 1995;La Mesa et al, 2002;Le Diréach & Francour, 1998;Macpherson, 1998;Macpherson et al, 1997;Morato et al, 2003;Planes et al, 1998;Raventós & Macpherson, 2005;Vigliola et al, 1998). These studies indicate that coastal fish species require shallow areas (o5 m) with rocky-boulder zones, sandy beaches, or seagrass meadows to settle and/ or recruit on.…”

SummaryThe success of MPAs in conserving fishing resources and protecting marine biodiversity relies strongly on how well they meet their planned (or implicit) management goals. From a review of empirical studies aiming at assessing the ecological effects of Mediterranean and Macaronesian MPAs, we conclude that establishing an MPA is successful for (i) increasing the abundance/biomass, (ii) increasing the proportion of larger/older individuals, and (iii) enhancing the fecundity of commercially harvested populations; also, MPAs demonstrated to be Meta-analysis; Mediterranean; Macaronesia effective for (iv) augmenting local fishery yields through biomass exportation from the protected area, and (v) inducing shifts in fish assemblage structure by increasing the dominance of large predator species. However, the attraction for tourism and diving due to ecological benefits of protection can cause damages likely to reverse some of the MPA effects. Other expected effects are more subject to uncertainty, and hence need more research, such as (vi) causing density-dependent changes in life history traits and (vii) protecting the recruitment of commercially important species, (viii) protecting marine biodiversity (including genetic diversity), (ix) causing ecosystem-wide effects such as trophic cascades, and (x) increasing community and ecosystem stability, thus promoting resilience and faster recovery from disturbance. Meta-analysis of data arising from these case studies are used to establish the overall effect of MPAs, and its relationship to MPA features, such as size of no-take area or time since protection. Based on the review and the metaanalyses, specific recommendations are provided for MPA management, regarding the establishment of goals and objectives, site selection, MPA design and zoning, planning, and monitoring. Finally, a series of recommendations for MPA research are offered to drive future research in MPA issues in the Mediterranean and Macaronesia.

Age, growth and mortality were analysed for the common twobanded seabream, Diplodus vulgaris, collected in the eastern Adriatic (Croatian coast) from commercial fishery catches by ÔtramataÕ fishing (2005)(2006) to obtain growth estimation. The oldest female was estimated to be age 11, the oldest male age 10 years. The von Bertalanffy growth parameters estimated by reading scales were: L ¥ = 48.60 cm (SE = 1.101), K = 0.112 (SE = 0.005) and t 0 = )2.366 (SE = 0.060) for all specimens; L ¥ = 51.96 cm (SE = 2.153), K = 0.095 (SE = 0.007) and t 0 = )2.837 (SE = 0.120) for females and L ¥ = 56.25 cm (SE = 2.662), K = 0.084 (SE = 0.067) and t 0 = )2.920 (SE = 0.117) for males. The overall sex ratio was 1.22 : 1 in favour of males. Total mortality, corresponding to the slope of the descending limb of the catch curve, was Z = 0.81 per year for females and Z = 0.85 per year for males. Exploitation ratios were E = 0.68 for females and E = 0.73 for males.
