A study on shell size frequency in freshwater snail Bellamya dissimilis collected in monsoon season

Pallavi Jadhav and Meena Patil

The present study was aimed to see the shell size frequency distribution of freshwater snail B. dissimilis in monsoon season collected from Godavari River near Kaygaon, Pravara Sangam, Aurangabad, Maharashtra, India. The distributions frequency is calculated on the basis of shell length, shell width, aperture length, aperture width and total body weight and its relation with shell length as in total collection of 208 animals. The average length of snail shell was 2.65±0.42cm. The average shell width was 4.45±2.94cm. The aperture length was 1.05±0.11cm. The aperture width was 0.79±0.12cm and the average of total body weight was 1.60±0.16g. Frequency distribution showed maximum number of snails shell length ranges in the group of 2.7-3.1cm, shell width ranges in the group of 4.1-4.5cm showed maximum number of snails, and maximum number of snails in case of aperture length and aperture width ranges in the size groups of 1.0-1.2cm and 0.7-0.9cm respectively. The size group 1.55-2.13g of Total body weight showed maximum number of snails. Results showed positive correlation significance at 1% level (p<0.01). The shell length is highly positively correlated with all body parameters except with shell width it was lowest but positively significant (p<0.05) with R value of 0.150.
