The Smithsonian Tropical Research Institute has released a free iPhone app, for the identification of Pacific fish species. The species covered spans from Baja California to Ecuador, including the Galapagos.
The app evolved from the book, “Fishes of the Tropical Eastern Pacific” published in 1994. However, the app covers over 1,300 species allowing the identification of 10% of the world’s tropical fish species whereas the book only has 700. The app is free on iTunes: here and is potentially one of three apps according to iTunes descriptions.
Having downloaded and played around with this app it is very easy to use. It has a clear lay out containing a notebook section where you can compile your own lists and each page comes with a glossary section for any words used that aren’t understood. When you click on one fish you will also see other members of the family before it goes directly to the profile page, allowing for a perfect match. I like the feature of being able to find out the IUCN red list status which is available on each profile page. A useful little app that I would recommend to anyone needing to identify any pacific fish species!
