Anglerfish (Lophius spp) in Nordic waters

image of Anglerfish (Lophius spp) in Nordic waters

The demand for anglerfish for human consumption has increased in the last couple of decades because of the delicate consistency of its meat. Accordingly, the fishing pressure has increased considerably in all Nordic fishing regions. Relatively little has, however, hitherto been known about anglerfish biology and ecology. Assessment and management of Nordic anglerfish stocks is difficult to conduct due to the paucity of fisheries and biological data. Answers to questions regarding the spawning behaviour, migratory behaviour and juvenile drift, as well as more knowledge about growth, sexual maturation, diet and natural mortality, would thus form crucial contributions to present and future management of Nordic anglerfish stocks. This report presents a review of the status of current knowledge and research on the biology, ecology, fisheries and stock management of anglerfish in Nordic and European countries, including results and publications from a three-year Nordic cooperative anglerfish research project (2002-2004). Preliminary attempts were made at estimating current levels of fishing mortality in the Nordic regions, and the yield and spawning stock per anglerfish recruit. Recommendations on future research are also given.

Investigation into the Suitability of Internal Data Storage Tags (DST) for Studies Involving Monkfish Lophius piscatorius

The use of tagging studies has become standard practice in the field of fisheries science. Studies using conventional tags (e.g. dart, T-bar, disc, Carlin) allow the collection of data on, for example, movement, verification of growth parameters and estimation of exploitation levels. The recent development of Data Storage Tags (DSTs), where data on external parameters can be logged (depth, temperature and now also light intensity) has resulted in the value of tagging studies becoming more pronounced.
