NEPTUNE SEMINAR SERIES | AIRES DUARTE | 8 MAR | 11:30

 

Title: Screening of seaweed species for cultivation associated with land-based aquaculture

 

Fish-farms produce as by-products nutrients that can be used by seaweeds to grow and, consequently, produce biomass that can be valorised in different applications. We aim to find specific seaweeds to grow in a fish farm effluent that has specific traits such as low salinity (~23%), moderate temperature (~19ᵒC), high and low levels of nitrates and ammonium, respectively. Six seaweed species were selected for this experiment. Seaweeds from North Coast of Portugal were collected, acclimated for seven days and exposed to this effluent for three weeks under the following conditions: 5gL-1, 19 ᵒC, 23 of salinity, ~150µmolphotons∙m-2∙s-1 and 12h:12h (L:D). Part of the effluent was adjusted to 33 of salinity to determine whether salinity was a limiting factor.

 

Name: Aires Duarte

 

Aires Duarte holds a degree in Biotechnology from University of Évora (2013) and a master’s degree in Functional Biology and Biotechnology of Plants from University of Porto (2017). After experiencing image and data analysis, he decided to come back and work once again with seaweeds. Aires is currently a PhD student at Coastal Biodiversity Team in CIIMAR working on seaweed cultivation. His research focuses on finding suitable seaweeds to reduce the excess of nutrients coming from a fish-farm.

 

The seminar will take place at CIIMAR headquarters (Boca da Baleia Auditorium).
