Historical information on cockle landings and studies local knowledge fishing, zoology, ecology in the Ria de Aveiro remain incomplete. Due to COVID-19 pandemic current conditions of artisanal fisheries Europe, understanding dynamics this activity has become even more necessary. Therefore, case study sought investigate changes that have taken place recent fishing decades verify degree contentme...

The present study was carried out for preliminary phytochemical screening for ten principle bioactive compounds in Petroleum ether, chloroform, ethyl acetate and ethanol extracts of roots of Memecylon edule collected from potheri forest, Kattankulathur in Tamilnadu. Chloroform and ethyl acetate extracts of seeds of Memecylon edule were also investigated against ten bacteria using disc diffusion...

Leaf samples of Solanum lycopersicum, Capsicum annuum, Cucurbita moschata, Cucurbita pepo, Sechium edule and Erythrina spp. were collected. All samples were positive for begomoviruses using polymerase chain reaction and degenerate primers. A sequence of ∼1,100 bp was obtained from the genomic component DNA-A of 14 samples. In addition, one sequence of ∼580 bp corresponding to the coat protein (...

Cockles Cerastoderma edule were fed two different concentrations ( approximately 0.8 and 2 mm(3) l(-1)) of two diets with different qualities ( approximately 10 and 60% of organic content) which were achieved by mixing different proportions of ashed silt particles with cells of the microalgae Tetraselmis suecica. Clearance, ingestion and absorption rates of organic matter and biochemical compon...

The impacts of climate change on the structure and functioning estuaries is a major focus concern, even more when affected species support important fisheries as bivalves Ruditapes decussatus , philippinarum Venerupis corrugata Cerastoderma edule in Europe. Their reproductive performance, context stressors, had not been investigated so far. Our objective was to experimentally evaluate acute str...
