Article
Full-text available
The green crab (Carcinus maenas) population was investigated in a coastal lagoon (Santo André) located on the southwest coast of Portugal. This study assessed the spatial-temporal variability of green crab abundance in the lagoon and its relationship with environmental variables. Experimental fishing was used to collect data on abundance, size stru...

Full-text available
In the framework of stock enhancement, field experiments were conducted between March and July 2021 in rocky shores of Central Portugal to test the usefulness of refuges and calcein marking for juvenile sea urchins releases. Individuals with 10–20 mm in test diameter were captured in nature and tagged through immersion in a calcein bath with a conc...

The sea urchin Paracentrotus lividus (Lamarck, 1816) (Echinodermata: Echinoidea) is an important economic resource in Europe, but intense harvesting has led to the collapse of several natural populations. Echinoculture, associated with restocking and stock enhancement practices, is an alternative to this problem. In these procedures, reliable indiv...

Age and growth of European eel (Anguilla anguilla) from a coastal lagoon in southwestern Europe were investigated using a sample of 871 eels. Fish were caught with fyke nets in two fishing seasons, 2011/12 and 2015/16. Age was determined by reading sagittal otoliths and age estimates were validated through semi-direct methods. The yellow and silver...
Article
The adoption of the EC Regulation 1100/2007 for the recovery of the European eel required EU member states to implement and periodically report on their Eel Management Plans (EMPs) with the goal of achieving at least 40% of the silver eel escapement relative to the best estimate of escapement that would have existed if no anthropogenic influences h...
Article
To provide new information on the ingress dynamics of glass eels at the Portuguese coast, the study analyzes catch per unit effort (CPUE) data from river Lis, biometric data from recruits in basins of western Portugal and meteo-oceanographic data from the Iberian margin and shelf. Biometric data of glass eels in western Portugal are congruent with...
Article
In the past three decades the European eel Anguilla anguilla experienced up to 99% decline in recruitment in some parts of its distribution range. In addition to this long-term trend, glass eel recruitment exhibits significant inter-annual variability partially explained by large-scale oceanographic processes as well as local-scale meteorological a...
Article
Full-text available
Landlocked lagoons are naturally stressed environments. They are strongly influenced by freshwater input which not only varies naturally, but which is also impacted by anthropogenic activities. This study investigated the direct influence of freshwater discharges on the distribution patterns and abundance of benthic communities in two neighbouring...

Full-text available
The European Waterframework Directive requires the assessment of ecological status of all water bodies, including rivers, estuaries, coastal areas, emphasizing that the status of surface aquatic ecosystems might depend on groundwater status. The assessment of the ecological status of coastal lagoons dependent on groundwater is particularly complex...
Conference Paper
Full-text available
The study of groundwater dependent ecosystems opened the opportunity to involve specialists of different areas of knowledge in order to obtain answers for complex interrelations between groundwater and the associated ecosystems. The actual study, carried out in two coastal lagoons of the Portuguese SW coast, showed the high dependency of the marine...
Article
Full-text available
This study aims to ascertain the structure of benthic macroinvertebrate communities of Santo André and Melides River Basins and understand how these communities are affected by different environmental variables. These are small river basins with a Mediterranean climate. The majority of the watercourses of these basins is temporary and dependent on...
Conference Paper
Full-text available
O principal instrumento da política da União Europeia relativa à água, a Directiva Quadro da Água tem como principal objectivo atingir o “bom” estado ecológico das massas de água, dando grande importância aos componentes biológicos dos ecossistemas. No âmbito desta directiva, o Índice Português de Invertebrados do Sul, que avalia a qualidade ecológ...

With the publication of the Water Framework Directive in 2000, Portugal and all other Member States of the European Community, assumed the commitment to achieve a good ecological status of all water bodies by the year of 2015. The accomplishment of this major objective requires the assessment of the current status of all water bodies. Benthic macro...
Article
Full-text available
The characteristic high variability and low predictability of coastal lagoons, due to strong changes in marine and freshwater inputs, make these ecosystems an interesting case study. The small Melides landlocked coastal lagoon in SW Portugal is a paradigmatic example, with a biological community highly stressed by these phenomena. Benthic macroinve...
Article
Full-text available
Land-locked coastal lagoons are naturally stressed environments that consequently constrain biological communities that colonize these systems, through direct or indirect influence. This study investigated the influence of groundwater outflows and catchment runoff on the fish community of Melides and Santo André, two land-locked coastal lagoons in...

Full-text available
The aim of the present work was to investigate variations in the structure of fish communities of Melides and Santo André lagoons related with the presence of groundwater-dependent permanent streams and runoff-dependent intermittent streams.
Article
Full-text available
La grande alose (Alosa alosa) et l’alose feinte (Alosa fallax) sont des poissons migrateurs anadromes menacés non seulement au Portugal mais dans toute leur aire de distribution géographique. La surexploitation et la pêche illégale, la pollution, les obstacles physiques et les modifications du lit des rivières semblent être les principales raisons...
Article
Full-text available
Only three cases of landlocked populations of allis shad (Alosa alosa L.) were reported until the present, being two of them in Portugal. In this paper, data on the feeding habits and condition of these two populations sampled between 1998 and 1999 are presented. Both populations are zooplanktivorous, with cladocerans (Family Daphniidae) and cyclo...

Full-text available
The present paper reports data from the first integrated study on resource partitioning among the most abundant fish species in the Obidos lagoon (Portugal). From July to December 1994, samples of fish were taken monthly, leading to a total of 414 individuals from 12 different species: Sardina pilchardus (Walbaum, 1792); Engraulis encrasicholus (Li...
