A Global Overview of Aquaculture Food Production with a Focus on the Activity’s...
Rocha, Carolina P.; Cabral, Henrique N.; Marques, João C.; Gonçalves, Ana M. M.World aquaculture food production rises every year, amounting, by 2018, to another all-time record of 82.1 million tonnes of farmed seafood, with Asia leading global production. In Europe, although coastal countries present historical fishing habits, aquaculture is in true expansion. Norway, the leading European producer, is the eighth main producer worldwide. Portugal is a traditional fishing country but has i...
Enzymes as useful biomarkers to assess the response of freshwater communities t...
Gonçalves, Ana M. M.; Rocha, Carolina P.; Marques, João C.; Gonçalves, Fernando J. M.The lack of specificity of pesticides used for control of various organisms, even if efforts have been made to design formulations more species-specific, produce harmful effects on non-target organisms. Oxidative stress and lipid peroxidation are amongst the main known effects induced by pesticide exposure, besides eventual lethal toxicity, endangering organisms’ biomembranes integrity or compromising their act...
Fatty acids as suitable biomarkers to assess pesticide impacts in freshwater bi...
Gonçalves, Ana M. M.; Rocha, Carolina P.; Marques, João C.; Gonçalves, Fernando J. M.The toxic effects associated to pesticides have been for long a concern in terms of environmental and human safety. The recognition of the limitations of numerous, if not all, pesticides in terms of species-specificity, toxicity level, persistency in the environment, influencing its runoff and transport ability, among other characteristics, have been the subject of numerous studies over the years. These have es...
Seaweeds’ carbohydrate polymers as plant growth promoters
Pacheco, Diana; Cotas, João; Rocha, Carolina P.; Araújo, Glacio S.; Figueirinha, Artur; Gonçalves, Ana M. M.; Bahcevandziev, Kiril; Pereira, LeonelCurrently, the high food demand led to a mass agriculture practices, whereas crop productivity is one of the major concerns for the producers. However, the intensification of the use of synthetic fertilizers has led to serious harmful impacts for human health and for the environment. The quest for novel and natural agricultural products is a current trend, hence seaweed polysaccharide bioactivity can contribute...
Portuguese Kelps: Feedstock Assessment for the Food Industry
Pacheco, Diana; Miranda, Giuseppe; Rocha, Carolina P.; Pato, Rosinda L.; Cotas, João; Gonçalves, Ana M. M.; Santos, Sandra M. Dias; Bahcevandziev, KirilSeaweeds have been incorporated in the daily diet of several human cultures since ancient times, due to their nutritional characteristics and healthy properties. The brown seaweeds Undaria pinnatifida, Saccharina latissima, Sacchoriza polyschides, and Laminaria ochroleuca were collected in the Viana do Castelo (Portugal) bay to assess their proximate composition analysis. As a result, the algal biomass was drie...
Biochemical Effects of Two Pesticides in Three Different Temperature Scenarios ...
Mesquita, Andreia F.; Gonçalves, Fernando J. M.; Rocha, Carolina P.; Marques, João C.; Gonçalves, Ana M. M.The exponential increase of the human population demands the overuse of fertilizers and pesticides in agriculture practices to suppress food production needs. The excessive use of these chemicals (fertilizers and pesticides) can comport deleterious effects to the ecosystems, including aquatic systems and communities. Oxyfluorfen is a fluorine-based herbicide, and its application has increased, since it is seen ...
