The FishBase 2000 release summarizes the accumulation and structuring of knowledge on fish biology and ecology over the more than 10 years since its inception. FishBase 2000 now covers over 25,000 species of fish known to science, has over 70,000 synonyms and 100,000 common names in over 200 languages. The names are the key to accessing knowledge accumulated over time and mobilizing scientific and non-scientific knowledge systems. Over 25,000 pictures illustrate these fish and information about them has been extracted from 20,000 references. The classification of higher taxa follows the version of EschmeyerâÂÂs Catalog of Fishes updated in November 2000.
