We encourage users to publish their primary research on growth, weight-length relationships, reproduction (maturity, fecundity, spawning), food and diet composition, introductions and range extensions for faster subsequent entry in SeaLifeBase. A few journal options are available, one of which is Frontiers in Marine Science, Marine Biology section (Impact factor 2021: 3.7) in which a few members of the FishBase Consortium are serving as associated and review editors.
