ABSTRACT In southern Iberia (NE Atlantic), cetacean bycatch is reported in several fisheries, whereas depredation by bottlenose dolphin ( Tursiops truncatus ) commonly observed bottom set‐net fisheries. This study tested the effectiveness of acoustic deterrent devices discouraging small cetaceans from approaching set‐nets and purse seine to reduce interactions. The used were interactive for fishery common Delphinus delphis bycatch. Data collection was carried out at‐sea observers trained...
This article shares the experiences, observations, and discussions that occurred during completing of an ecosystem services (ES) indicator framework to be used at European Union (EU) Member States' level. The experience base was drawn from 3 research projects 14 associated case study sites include 13 transitional-water bodies (specifically 8 coastal lagoons, 4 riverine estuaries, 1 fjord) coastal-water ecosystem. ES pertinent each site were identified along with indicators these data sources...
Marine Protected Areas (MPAs) are a tool to safeguard marine natural systems, yet their effectiveness depends on how well they integrated into the existing socioeconomic context. Stakeholder engagement in MPA design can contribute increasing integration. This study focuses co-design of an between researchers, public administration, private sector, and non-governmental organizations. The proposed is Portugal includes area that hotspot for biodiversity economic activities. first proposal...
A longline 'metier' using small hooks for 'red' sea breams (Pagellus acarne and Pagellus erythrinus) in the Algarve (south of Portugal) was studied. Experimental longlining carried out with three sizes "Mustad" round bend, flatted, spade end Quality 2316 DT (numbers 11, 13 15) two types bait: razor shell (Ensis siliqua) mud shrimp (Upogebia pusilla). total 3 328 fish at least 36 species were caught 33 600 fished 28 sets. Five (Sparidae) accounted 79% catch: acarne, erythrinus, Diplodus...
Weight–length relationships (WLRs) are presented for 54 species sampled by several types of fishing gear between February 2004 and May 2007, in the Arade estuary (southern Portugal). WLRs six first time.
Fishing trials with monofilament gill nets and longlines using small hooks were carried out in Algarve waters (southern Portugal) over a one-year period.Four hook sizes of "Mustad" brand, round bent, flatted sea (Quality 2316 DT, numbers 15, 13, 12 11) four mesh 25, 30, 35 40 mm (bar length) used.Commercially valuable breams dominated the longline catches while pelagics relatively more important nets.Significant differences catch size frequency distributions two gears found for all most...
The relationship between fish total length (TL) and mouth size in six species was investigated light of the implications for modelling selectivity hooks. Significant non-linear relationships were found three species, suggesting that optimal at capture is not a linear function hook size. These results strongly support choices made skew-normal with as
Discards from five of the most important fisheries (crustacean trawling, fish demersal purse seining, pelagic seining and trammel netting) in southern Portugal were studied compared. A total 236 species all taxa discarded, with cephalopods accounting for more than 90% discarded biomass, except nets (81%). Although there was some overlapping species, multivariate analysis using cluster classification multidimensional scaling (MDS) ordination, showed that significant differences between gears...
In Portugal, elasmobranch landings have decreased substantially in recent years.In this work, catches semi-pelagic longlines (1997 and 1998) were compared with those trammel nets (2000) the Algarve, southern Portugal areas.In longline fishery, 7 species represented 33.4% (2 185 specimens) of total fish catches.Among species, most abundant Galeus melastomus (63.3%),Etmopterus pusillus (21.7%) Scyliorhinus canicula (14.2%).Most these elasmobranchs discarded (68.3% total).In net 16 different...
Samples of Boops boops ranging from 7.4 to 30.5 cm were obtained mainly by longline, supplemented beach seining in the Ria Formosa lagoon, and market sampling Algarve (southern Portugal).
