Kelp has properties that may help roe crackers thrive, but this has not yet been well documented.
It has been shown in previous research that growth on nuts does not have a negative effect on lice eating. Also, pilot data indicates that cages with a lot of kelp growth on the net have healthier roe crackers than those with clean net. In addition, there are indications that kelp has a microbiological effect on the environment, which could possibly help roe biscuits to resist infections in the skin or on the fins. As roe crackers are very susceptible to infections, the soft kelp can make a big difference to the roe crackers' well-being. In addition to the possible positive effect of kelp on the well-being of the roe crackers, it stays clean and can be attractive to the salmon. This can lead to more interaction between salmon and roe biscuits. Thus, kelp hiding can potentially have two positive effects for roe crackers as cleaning fish: a) increases well-being so the roe crackers are better able to clean. Main objective: To investigate the effect of AkvaNest kelp shelter on welfare and lice eating in roe crackers.
Sub-goals:
1. To establish a reliable method for observing louse eating (work package 1 (AP 1)).
2. To determine the suitability of live kelp cover for the promotion of good roe cracker welfare (AP 2+4).
3. To determine whether the use of live kelp hides increases lice eating according to both activity and effect (AP 3+5).
