Abstract Leitão, F., Santos, M. N., and Monteiro, C. 2007. Contribution of artificial reefs to the diet white sea bream (Diplodus sargus). – ICES Journal Marine Science, 64: 473–478. An evaluation trophic relationship between Diplodus sargus (ARs) in Algarve (southern Portugal) is based on a comparison stomach contents macrobenthic communities present at AR surrounding sandy bottom areas. Only adult were observed vicinity ARs. The percentage items found that characteristic hard substratum...
Plastics is all the rage, and mitigating marine litter topping agenda for nations pushing issues such as ocean acidification, or even climate change, away from public consciousness. We are personally directly affected by plastics charismatic megafauna dying it, it something that appears to be doable. So, who cares about issue of acidification anymore? should. The challenge dual in fact both invisible naked eye therefore not felt like a pressing public, thereby reaching top policy makers; but...
This is the first attempt to apply an expert-based ecological vulnerability assessment of effects climate change on main marine resources Portugal. The vulnerability, exposure, sensitivity, adaptive capacity, and expected directional 74 species fish invertebrates commercial interest estimated based criteria related their life-history level conservation or exploitation. analysis performed separately for three regions Portugal two scenarios (RCP 4.5 RCP 8.5). To do that, fourth report IPCC...
Boating tourism in coastal-maritime areas often overlaps spatially and temporally with other economic activities, such as fishing, leading to complex interactions. These interactions can create opportunities for positive cooperation or generate conflicts that pressure natural resources stakeholders. This study focuses on the interplay between maritime-tourism activities fishing south of Portugal, using a social network analysis (SNA) approach based automatic identification system (AIS) data...
Abstract Artificial reefs (ARs) have been deployed in Algarve (Southern Portugal) coastal waters to contribute the sustainability of local nearshore fisheries. Herein, we describe colonization process recently Faro/Ancão AR, and assess time until fish assemblage reaches stability their seasonal patterns. In addition, compare results from present study with those previously reported for an older AR. The assemblages were monitored monthly over a 2‐year period by means visual census. A rapid...
Abstract Artificial reefs have been deployed along the southern coast of Portugal (Algarve) since 1990 to enhance artisanal fisheries. The objectives this study were to: (1) describe colonisation process; (2) assess role artificial in terms juvenile recruitment and growth as mating/spawning areas (3) evaluate potential near shore fishing grounds for three economically important fish species, Diplodus bellottii (Steindachner), sargus (L.) vulgaris (Geoffroy Saint‐Hilaire). assemblages...
Polovina published the article “ Artificial reefs: nothing more than benthic fish attractors” in 1990 and it debated potential for artificial reefs to substantially increase standing stock of marine resources. Reef (AR) technology was strictly oriented towards improving commercial fishing (STONE et al., 1991) from 1930s, when Japanese government invested large scale reefs, until 1990´s. The first three International Conferences on Reefs Related Aquatic Habitats (CARAH) focused improvement...
In southern Portugal, artisanal octopus fisheries play an important socioeconomic role. Live crab bait in traps was used up to 2010 and banned 2012. Such regulation, based on co-management advice, not established under a scientific fundament. As result, long-standing controversy ensued with some fishing associations claiming that live increased effort exploitation rates therefore risked the stock status, while other fishers denied all these alleged impacts. The issue has been resolved so far...
Abstract The white clam Spisula solida is harvested along the entire coast of Portugal using mechanical dredges. In this study, total direct mortality macrobenthic community caused by three types dredges (north dredge—ND, traditional dredge—TD, and metallic grid dredge—GD) used in S. fishery was determined compared. relationship between catching efficiency for each type dredge also assessed. Our results showed significant differences ND both GD TD This difference largely attributed to...
Despite the importance of dredge fishery in Portugal, few studies have focused on bycatch and discard mortality. Catches from three types dredge: north (ND); grid (GD); traditional (TD), currently used Spisula solida (Bivalvia: Mactridae) fishery, were compared order to characterize estimate In TD ND, catch was retained a net bag, whereas GD metallic cage used. Tows carried out sandy bottoms at depths ranging 5 10 m. Bycatch differed significantly between dredges. The ratio abundance S....
ABSTRACT Overall an increase in sea surface temperature ( SST ) has been recorded over the last century. However, changes are not homogeneous across ocean. Most studies focus on processes and mechanisms setting variability broad scales neglect occurring at a regional scale. So, this study aims to describe annual, seasonal monthly time‐series trends along Portuguese coast, compare among areas (Northwest, Southwest South), quantify rates discontinuities. Time‐series analyses showed that same...
Abstract The environmental effects of climate change are expected to impact fisheries, and related economies, represent a significant challenge for the development government policy. ocean warming on fisheries yields is particular concern. effect sea surface temperature (SST) in three distinct biogeographic areas (north‐western, NW; south‐western, SW; south, S) different fleet sectors (trawl, seine, multi‐gear) Portuguese coast was examined. mean catch (MTC) applied official landings...
Coastal upwelling has a significant local impact on marine coastal environment and biology, namely fisheries. This study aims to evaluate climate environmental changes in trends between 1950 2010. Annual, seasonal monthly were studied three different oceanographic areas of the Portuguese coast (northwestern—NW, southwestern—SW, south—S). Two sea surface temperature datasets, remote sensing (RS: 1985–2009) International Comprehensive Ocean—Atmosphere Data Set (ICOADS: 1950–2010), used...
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities sensorial acuity of temperate fish larvae allows them to find swim towards coastal nursery areas, which are crucial for their recruitment. To gather further evidence support this theory, it is necessary understand how horizontal capability varies along ontogeny. Therefore, we studied white seabream Diplodus sargus (Linnaeus, 1758) ontogeny, relationship with physiological condition. Thus, critical speed...
