Fish Ageing by Otolith Shape Analysis ICESGrinding POLISHER FISH OTOLITH,Otoliths grow continuously throughout the life span of the fish and their speciesspecific shape develop from a simple, often eel otoliths are aged by counting annuli after grinding and polishing in a sagittal or transverse plane otolithscentre of the
The study of otolith microstructure has become increasingly more important in recent years to help determine fish age, growth rates, environmental factors, and other important aspects to fish microstructure Campana, 1985. Related to this increase in study is the sample preparation techniques implemented for the study of otolith microstructure.
6. Trim excess mounting media around the otolith using an IsoMet Precision Saw with a 15LC blade. This will save preparation time by reducing the surface area of epoxy that needs to be removed in the grinding process. A parallel cut will also insure that the correct polishing plane is established.
On thin, polished otolith layers the annual growth rings, as well as supernumerary zones formed in fresh water, could be easily distinguished. The described equipment and grinding procedure gave good results on permanent preparations, allowing repeated agereadings. The procedure appears to be applicable to other fish species as well.
After polishing with waterproof silicon carbide grinding paper grain size of 5m, otoliths in immersion oil were examined with a digital microscope Keyence VHX5000 using transmitted light at
orientation during the polishing process. Specimens were mounted onto a pyrex stub using Quickstick135 thermal wax. The preparation and observation of fish otolith bones are used to reveal micro structural details which helps researches determine fish age, growth rates, environmental factors, and other important aspects to fish microstructure.
The time required to completely polish an otolith from one side varies with the size of the otolith and the skill of the polisher. Typically though, an experienced polisher can polish a 100m otolith in 15 minutes. The following image pairs show a trout sagitta glued to a slide as it moves through the polishing process.

The correlations between the height of the otolith and the height of the fish, and length of otolith and length of the fish, indicate that otolith and fish grow in parallel. While both otolith and fish growth might pause in unison, it cannot be argued that the otolith continues to grow after the fish has stopped growing. Fig. 8A Fig. 8B
