Commercial aggregations of alfonsino (Beryx splendens) on the Corner Rising and in the area of North Azores were discovered for the first time on board the USSR exploratory vessels the mid-70s of last century. The NAFO SC recommended that precautionary regulations of the mid-water trawl fishery on splendid alfonsino be put in place. In 2014 NAFO Fisheries Commission request for scientific advice on provide a stock assessment for alfonsino. Taking in account the alfonsino spatial distribution associated with seamounts, their life history and their aggregation behavior and due to the limited availability of data it could be advised a scalar approaches to advice the future catch levels by using simple scalar multipliers applied to current or historical catch patterns. Based on this approach a maximum catch limit of 200 tonnes (the mean of the last 6 years) on 16-18 days or around 120 fishing hours could be advised by year in Kükenthal seamount and recommend that the exploitation of new seamounts should not be allowed to prevent the exploitation of populations that have not yet been fished.
