Image Analysis

The Laboratory of Image Analysis (Image Analysis) uses modern techniques of optical imaging and advanced technology equipment (tablets, video, frame grabber and digital still cameras). It includes an analysis and processing system for digital microscopic images, consisting of analog and digital cameras adapted to microscopes and stereoscopes, which are connected to respective workstations. The system is supported by detection applications, counting and morphology objects.

For further editing of photos and video, digital image analysis software is used (Adobe Photoshop, Correl Draw, GraphicConverter and NIH Image). Image Analysis is mostly used for age studies (otoliths , statoliths) and for fish and cephalopods reproduction analyses. Apart from the two -system software (Image Analysis Pro Plus and TNCP), macros have been constructed and used for age and reproduction studies.


The Ichthyoplanktonic Laboratory used for processing, analysis and storage of samples of ichthyoplankton that is collected during research cruises. Facilities include a wet lab separation and sorting for ichthyoplankton, sample splitters, stereoscopes and microscopes.


The Histology lab has complete and modern equipment for obtaining histological samples through dehydration process, dwell, production and corresponding staining sections. The above process is carried out to analyze species and populations mainly in studies of fish reproduction (defining developmental stages of germ cells, classification stages of maturity , daily and seasonal spawning pattern, fertility, reproductive condition assessment , etc. )


Ichthyology laboratories are equipped to meet the needs of the research carried out by the Institute on demersal and pelagic species caught by experimental fishing or procured directly from the fishermen. In the laboratory, morphometric studies are conducted, biological parameters are recorded and appropriate organs are removed for further analysis and study (e.g. studies on age, histological studies such as gonadal lipid analyses, etc).

The laboratory includes washing facilities, instruments for measurements, such as  ichthyometers, digital calipers and analytical scales, instruments for cutting and polishing (for otoliths)  and lipid analyzers. The lab equipment also includes microscopes and stereoscopes -enabled camera and with Image Analysis System.
