The Ballan wrasse is placed in the net pen together with the farmed salmon, where it provide its cleaning service to the salmon. To assure good access of ballan wrasse for the salmon the wrasse itself is now being farmed for the purpose. Although important steps towards production of efficient and healthy B. wrasse have been taken, there are still many questions in need of answerers. A main challenge in B. wrasse production is to formulate diets that give good feed intake, growth and fish health in the ongrowing and broodstock stages, challenges related to the unique digestive system of the species. Wrasses have a short intestine (2/3 of body length) with no stomach or pyloric caeca. A better understanding of the basic biology of digestive functions is therefore vital to facilitate diet formulation and feeding regime to improve the overall production.
This project will lead to understanding of mechanisms underlying effects of dietary composition on passage rate and nutrient digestibility, and establish how the intestine regulates the passage of feed, and how appetite-signaling (hormones) may be involved. Further, the basic characteristics of the gut's immune responses, the volumetric development of organs from larvae to mature stages, and effects of dietary immune challengers and stimulators, and how intestinal inflammation affects digestion will be investigated.
