Length-weight Relationship of the Marine Gastropod Chicoreus brunneus (Link, 1807) from Thoothukudi Coast

Aims: This study aims to study the length weight relationship of the marine gastropod Chicoreus brunneus (Link, 1807) from Thoothukudi coast. Place and Duration of Study: A total of forty five (45) individuals of Chicoreus brunneus were collected from the Thoothukudi coast in the month of June 2024. Methodology: Length-weight measurements were done after all the collected samples were cleaned. Vernier calipers with an accuracy of 0.05 mm were used to measure the length and a digital weighing scale (Mettler Toledo balance) with a sensitivity of 0.01 g was utilized to weigh the specimens. Parameters of the length (L) and weight (W) relationship were estimated by using the formula W = aLb, where W represents the total weight; a is the intercept indicating the initial growth; L refers to length and b represents the relative growth rates of the variables and provides information on growth. Results: The total length of Chicoreus brunneus ranged from 4.8 cm to 8.5 cm while the weight ranged from 9.2 g to 32.38 g. Total mean length was calculated as 6.35±0.78 cm and total mean weight was calculated as 18 ±6.35 g. A linear regression study found a substantial positive association between length and weight (b=2.567, P
