Long-term incorporation of Selenium and Zinc in microalgae Isochrysis galbana and Nannochloropsis oculata and its effects on rotifer
(Wiley, 2022-03-16)
Rotifers are widely used in hatcheries to feed small-sized aquatic larvae although one of their disadvantages is the lack of zinc and selenium 5- and 30-fold lower than in copepods, respectively. To ...
Pinna nobilis in suboptimal environments are more tolerant to disease but more vulnerable to severe weather phenomena
(Elsevier, 2020-11-30)
We examined a disease outbreak of the fan mussel, Pinna nobilis (L.), in the Alfacs Bay (South Ebro Delta, Spain) during a period of two years in three zones exposed to a summer salinity gradient resulting ...
