ANALYSIS - In this week's news, researchers at NIFES, Norway, are a step closer to finding the perfect feed for ballan wrasse, writes Lucy Towers, TheFishSite Editor.

The study describes what is believed to be the optimal nutritional composition of feed for wrasse as: 65 per cent protein, 12 per cent fat and 16 per cent carbohydrates.

The research team also found that the wrasse used in aquaculture to combat sea lice were not being fed sufficient amounts of certain micronutrients such as taurine, calcium, phosphorus and vitamins, A, D and K.

Leading global salmon feed supplier EWOS is now independent and set for growth after its sale to private equity companies Altor Fund III and Bain Capital was completed.

Commenting on the closing of the transaction, Cermaq CEO Jon Hindar stated: "I trust that this transaction will provide good development prospects for EWOS, its employees and the new owners, and Cermaq look forward to continue the strong and important collaboration with EWOS in the coming years."
