Establishment of Osmundea pinnatifida mariculture
My project is multidisciplinary and focuses on the cultivation of Osmundea pinnatifida, a small red seaweed also called pepper dulse. This species is becoming to be particularly appreciate due to its unique taste, and is used as seasoning, charming chefs all over Europe.
Right now it is just collected from the wild and sold dry by different companies, even in Scotland. However, natural harvesting of seaweeds is not a sustainable practise and due to the increasing demand of seaweeds and seaweed products, aquaculture is becoming a must, and new species are starting to be investigated for biochemical/nutraceutical/pharmaceutical applications.
To date, no cultivation systems for O.pinnatifida have been established. However, establishing a successful cultivation of this species will guarantee a continued production of it, without seasonal limits and without affecting natural populations. It could also guarantee the tailoring of the product according to the market needs.
My project focuses on molecular analyses of the species investigated, using DNA barcode on rbcL gene and phylogenetic analyses of the samples investigated within them and with other red seaweeds.
The nutrient profile of wild and cultivated samples is being investigated in order to assess the protein, carbohydrates, lipids, pigments, phenolic compounds, antioxidant compounds, minerals and metals composition of the species. This is important to identify the best moment for harvesting wild samples to start a cultivation and also to tailor the product in order to meet the demands of the market in term of product quality.
Different cultivation systems (in tank and out in the sea) are tested in order to obtain an increase in yield and ensure a sustainable and efficient production of the species.
Cryopreservation methods will be investigated to try to store the most promising strains.
