[04/11/2018] 6th Internationational Otolith Symposium in Taiwan. :
Next week (15-21/04/20018) start the 6th Internationational Otolith Symposiumin in the National Museum of Marine Science & Technology (NMMST), Taiwan. Quarter century has passed since the 1st International Symposium on Fish Otolith Research and Application held at Hilton Head, USA in 1993. The symposium started to bring up a platform for people who work on fish otolith at varied objective to discuss and share experiences, and the series of international otolith symposium (IOS) was followed by 2nd IOS1998 in Bergen (Norway), 3rd IOS2004 in Townsville (Australia), 4th IOS2009 in Monterey (USA) and 5th IOS2014 in Mallorca (Spain). For the first time ever, the 6th IOS2018 will be held in Asia, a rather different atmosphere and culture for experiencing and a nice chance to review the advances of otolith research in the past 1/4 century. Also, the aim of the symposium is not only focus on fish otolith, but for the exploration of the information encoded in all types of calcified tissues (otoliths, scales, bones, shells, corals, etc.) as tools to support sustainable management and use.

[11/02/2017] Taxonomic changes in AFORO based in Nelson et al. 2016:
AFORO follows the recent taxonomic order used by Nelson et al. 2016. If well at family level the change are not dramatic, some families are split in three as Macrouridae, (now Macrouridae, Trachyrincidae and Bathygadidae) and other families are merged into other as is the case of Phycidae included into Gadidae.

[10/05/2017] A mapa mundi with otolith locations was included:
This map is interactive and permit to acces to otolith information in each location.

[05/03/2017] otoliths of Lessepsian invader species:

[10/10/2016] relationship otolith length vs fish length (OL-FL):
Based in the paper of J. Gimenez et al 2016 "Relationships between otolith and fish size from Mediterranean and northeastern Atlantic species to be used in predator-prey studies" in Journal Fish Biology, AFORO team provides potential equations between fish length and otolith size for fishes of different areas Since most of the regressions (ca. 84%) presented a high percentage of explained deviance (>75%), our data will be useful for dietary studies on piscivorous predators. You can access to the dinamic table clicking in the OF-FL function in home page.

[03/15/2016] AFORO reaches to 5000 images:
Thanks the recent uploads from specimens and pictures given by Szymon Smolinski from Poland, Andy Padilla from Alaska, E. Vasilyeva from Russia and C.H. Lin and C.W. Chang from Taiwan, AFORO reaches up to 5000 images of otolith sagittae, bellowing to 1519 species.

[02/19/2015] 300 Mediterranean species:
Despite the low diversity of the Mediterranean Sea fishes, AFORO reach to represent 300 species.

[12/12/2014] wavelets are here:
Now, you can calculate wavelets from otolith outline in polar coordinates. You can upload images in the AFORO system and download numerical results. Wavelet transform representation allows quantifying the irregularities of the contour and determining its precise position. These properties make these techniques suitable for pattern recognition purposes as stocks or species recognition (Parisi-Baradad et al 2010). These routines were developed in MATLAB® language.

[07/07/2014] All otolith morphometries restarted and uploaded:
The otolith sagitta morfometries of the all specimens were included now in AFORO. More of 4,500 images were represented by five morphological parameters: fish length (TL, SL, FL, etc.); area (Oa); perimeter (Op); length (Ol); width or heigth (Ow)of the otoliths and 3 indices; aspect ratio (OW/Ol); otolith relative length(100X(Ol/TL)); Otolith relative size(1000X(Oa/TL2))

[10/17/2013] 5th International Otolith Symposium 2014 (IOS2014):
Symposum will be in 20-24 Mallorca, Balearic Islands in October 2014. Strategic objective: The aim of the symposium is the exploration of the use of calcified tissues as tools to support management and the formulation of a definition of indicators at environmental, community, population, and individual levels. Scope: Implementation of ecosystem-based approaches to marine management points to several shared objectives between conservation and fishery management that require better knowledge of the life history of the exploited resources, elucidation of the information encoded in the calcified tissues (otoliths, scales, bones, shells, and corals) of marine and freshwater organisms, and support for knowledge-based, sustainable ocean management and use.

[09/26/2013] Download morphometry software:
This software calculates morphometry of an otolith given an image of this one. The output it is a file that contains the area, perimeter, length, width and aspect ratio of the otolith.

This software is currently only available for Windows operating systems.

[01/15/2013] Now, AFORO shows 3D images:
Since 2002, AFORO has been developed image analysis systems and database framework to give solutions in automatic identification of fish species and populations in base to otolith contours. The main objective of the project AFORO3D (CSIC, UPC, UVic and UB) is to create three dimensional (3D) morphological descriptors targeted to whole otolith and analisys tools in order to classify. The 3D objects are acquired at the Institut de Ciències del Mar (CSIC) using a single-camera 3D Scanner system based in projected LED light and developed by the Universitat de Girona (VICOROB) and AQSENSE company. The AFORO site and database are modified to support 3D information.

AGE&SHAPE is a comercial software developed by INFAIMON SL and based in the otolith research of UPC, IMEDEA and CMIMA teams and cofinanced by Spamish Goverment (PTR1995-0810-OP). AGE&SHAPE is composed, as suggested by its name, by two separated parts: age and shape. “Age” is devoted to determining the animal growth/time relation, with the aim of identifying, counting and measuring the growth rings, and “Shape” is in charge of determining the otoliths’ shape (or any other object) based on the relation between the external contour and its nucleus. SHAPE subprogram computes Cartesian and a polar outline representation. Contour analysis is done by computing its Fourier (FFT) or wavelet transform (DWT).

Also we keep implemented a public web site and a database of otoliths with its corresponding shape analysis and classification system . You may access to it at the following address: or We have developed several techniques based on Fast Fourier Transform, Wavelets and CSS (curvature space scale) specifically focused on providing mathematical descriptors of the otolith shape, through its contours, and extracted from high resolution images of otoliths. The database at present contains more of 1200 high resolution otolith images corresponding to more than 320 species from 97 families, mainly from Western mediterranean, Weddel Sea. You may find the shape analysis of each sample and compare among related samples. We have been aware of your guide of otholith through the internet and it should be very interesting for us trying to make some kind of cooperation. In particular we are obviously very interested on including more and more species from everywhere and your collection and the images seems to us very suitable. We invite you to visit our web pages and see the kind of information we offer through the database. If you find that this should be of interest to you we can keep in contact and try to find a way for mutual cooperation.
