Start year 2010 End year 2013 Funding (€) € 1,500,000 Website https://www.fhf.no/prosjekter/prosjektbasen/900482/ Summary Salmon lice infections pose a serious threat to the sustainability of the salmon industry in terms of fish welfare, environmental impacts and economic profitability. The situation has recently become more serious due to appearance of lice populations with reduced sensitivity to medical treatment. The use of cleanerfish has shown an effective, non-medical alternative to drug use.
The industry partners involved Marine Harvest Labrus (MHL) and Villa Organic (VO), see this environmentally-friendly method as the primary solution to combat sea lice. However, the sustainable supply of wild caught wrasse will most probably not meet local demands in the future. It is therefore of great importance that a commercial, large scale production of cleanerfish is built up.
Institute of Marine Research (IMR) has, in co-operation with VO, developed a basic protocol for production of the Ballan wrasse (Labrus bergylta), a large and efficient cleanerfish, also during winter time. MHL started commercial production of this species in spring 2009. An optimal broodstock diet is necessary for production of viable eggs and larvae, but no nutritional studies of broodfish have yet been conducted. Also, knowledge on nutrient requirement for offspring is lacking, and little is known about optima temperature for the different stages.
• To further improve current production protocol for Ballan wrasse (Labrus Bergylta) with focus on nutrition and rearing conditions.
Objectives:
• To optimize the use of farmed Ballan wrasse in commercial scale salmon production.
Specific objectives
1. To develop a broodfish diet that ensures good egg quality and healthy broodstock, by optimizing both macro- and micronutrient composition
2. To optimize technical and nutritional quality of weaning diets.
3. To reduce the need for live feed and identify the best weaning point
4. To ensure optimization of rearing temperature and evaluation of the effect of different protein quality in feed for juvenile fish.
5. To compare different light sources, under large scale conditions, with respect to growth and survival through larvae and early juvenile stages
6. To optimize the use of ballan wrasse as cleaner fish under commercial productions, covering the periods:
a) post smolt and early ongrowing phase (0.1 to 2.0 kg)
