Growth and extremely high production of the non-indigenous invasive species Corbicula fluminea (Muller, 1774): Possible implications for ecosystem functioning
Corbicula fluminea is a fundamental element in the River Minho estuary, possibly sequestering a large portion of the carbon available for benthic production and altering the ecosystem functioning and should be considered when modelling the nutrient cycles and energy flow in aquatic ecosystems.

Evidence of DUI is presented in the clam Donax trunculus making Donacidae the sixth bivalve family in which the phenomenon has been found and the taxonomic affiliation of all species in which DUI is currently known to occur is presented and a phylogeny of the maternal and paternal genomes of these species is constructed.
Shell morphometric relationships of the most common bivalve species (Mollusca: Bivalvia) of the Algarve coast (southern Portugal)
This study reports shell morphometric relationships (height/length and width/length) for the most common and abundant bivalve species of the Algarve coast (southern Portugal) and several ecological hypotheses or explanations were formulated for the distinct types of growth exhibited by different bivalves.
Age determination and growth rate of a Callista chione population from the southwestern coast of Portugal
The age and growth of the smooth clam Callista chione from the southwestern coast of Portugal were estimated during a 1 yr study period by using both the surface growth rings and internal shell…
Growth and reproductive cycle of Donax trunculus L., (Mollusca : Bivalvia) off Faro, southern Portugal
It is demonstrated that periodicity of the deposition of microgrowth bands was related to an innate rhythm and the age of clams can be determined more accurately from acetate peels than directly from surface rings.
Weight–length relationships for 50 selected fish species of the Algarve coast (southern Portugal)
The first references on weight–length relationships for six fish species worldwide are presented, for 15 species for the northeastern Atlantic, for 20 species for Portuguese waters and for 25species for the Algarve coast (southern Portugal).

Weight–length relationships of some of the most abundant bivalve species from the Algarve coast (southern Portugal) captured during several exploratory fishing surveys carried out during 2000 on a…
Abiotic impacts on spatial and temporal distribution of Corbicula fluminea (Müller, 1774) in the River Minho estuary, Portugal
Improved ecological knowledge is essential for future C. fluminea management, in order to protect local habitats and biodiversity, and to reduce the economic impact of this non-indigenous invasive species.
A comparison of direct macrofaunal mortality using three types of clam dredges
The white clam Spisula solida is harvested along the entire coast of Portugal using mechanical dredges. In this study, the total direct mortality of the macrobenthic community caused by three types…
Small scale fisheries in Europe: A comparative analysis based on a selection of case studies
Small-scale fisheries have traditionally received less research effort than large-scale fisheries and are generally under-studied in Europe. In spite of their comparatively low volume of catches and…
