Six products make up the initial offering with typical recipes including tuna with a lime and black pepper dressing and tuna in a tikka dressing.
Princes plans to celebrate their arrival on UK shelves later this month with a £1m push which will include instore promotions.
The range will be available in a range of pack formats, including 160g cans, twin packs of 80g cans and 85g pouches with rsp's ranging from 69p for the pouches to £1.19 for the twin packs. Natalie Johnson, fish marketing manager for Princes, said: "Consumers are looking for rapid, fuss-free meal options but there is also a growing awareness of the importance of a healthy, balanced diet.
"Our aim is to provide consumers with a wide range of ready-to-use products that are low in fat but don't compromise on taste."
She said the range was designed to appeal predominantly to women consumers, hence the tie-up with Weight Watchers' rival Slimming World.
Allison Brentnall, marketing manager for the slimming organisation, said: "Princes is a tried and trusted brand in the canned fish sector and this new range will tap into this existing strength, as well as building on consumers' trust in our brand."
