"The stereological determination of reproductive indices in bivalve shellfish is accepted as standard and is a reflection of changes in gonadal development and thus can be predictive of spawning activity and industry meat yield. The measurement of gonadal characteristics associated with calculation of the above indices has been traditionally limited to small sample number due to the time and effort involved in making individual measurements. The evaluation of larger sample sizes would be beneficial as it is more representative of the population of interest. In the current paper we have applied tools from ArcGIS software (ArcGIS, 2016) designed for spatial analysis to measure histological features from photomicrographs of bivalve mantle and applied these to the calculation of reproductive indices like gonad volume fraction"--Abstract.
