New PhD thesis: Exploring potential causes of gaping in salmon

Research: Ása Jacobsen, researcher at Fiskaaling, will defend her PhD on Friday at 1.00 pm in Kongshøll at the University of the Faroe Islands. 

The title of the new PhD project is "Exploring potential causes of gaping in salmon (Salmo salar L.) fillets."

As the world’s population continues to grow the demand for animal proteins for food follows suit. Farmed salmon, then, attracts due attention as an important food resource.

Aquaculture requires less resources than traditional production of land-based farm animals. However, the increased production of salmon calls for measures to meet sustainability requirements.

Gapes are slits between muscle blocs, resulting in loss of fillet firmness. This is a quality issue, which the industry hopes to see resolved, and, also, it is a sustainability issue.

The project explored gaping as a result of insufficient cleaning of the salmon’s abdominal cavity. The project also looked for a connection between the quantity and structure of certain molecules in the connective tissue and gaping.

Ása Jacobsen’s PhD was supervised by professor Svein-Ole Mikalsen at the University of the Faroe Islands and Jonhard Eysturskarð, researcher at Fiskaaling/Bakkafrost.

The PhD committee consists of Dr. Sissel Beate Rønning (Chairperson), researcher at NOFIMA (Norwegian Institute for Food Research), Dr. Phillip Pope, senior lecturer at Norwegian University of Life Sciences, and Dr. Samuel Martin, professor at the University of Aberdeen.

The co-authors are: Svein-Ole Mikalsen, Hóraldur Joensen and Jonhard Eysturskarð.

The PhD project has been produced in collaboration with P/F Fiskaaling and the University of the Faroe Islands.

Fiskaaling congratulates Ása on her significant achievement.
