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.

A note on the development of the embryos of anglerfish

Anglerfish Lophius piscatorius L. release their eggs embedded in a large buoyant gelatinous matrix commonly known as an ‘eggmass’, ’ribbon’, ‘raft’ or ‘veil’. The ribbon floats in surface waters as the embryos develop (Bowman, 1920) but ribbons are reported infrequently and they are rarely obtained for study. Descriptions of developing L. piscatorius embryos in the ribbon are limited to those given by Prince (1891), Fulton (1903) and Bowman (1920).
