ABSTRACT This present study investigates the length‐weight (LWRs) and length‐length (LLRs) relationships of three gobiid fish species, viz., Odontamblyopus rubicundus , Eleotris fusca, and Stigmatogobius sadanundio , from the mangrove reserve area of the Matla River in West Bengal, India. A total of 365 samples were collected monthly from July 2023 to March 2024 using various fishing gears with varying mesh sizes. Out of all the species evaluated, only O. rubicundus did not fall within the predicted range of 2.5–3.5. The 95% confidence interval (CI) and Pauly's t ‐test of b values were tested. Two species, E. fusca and S. sadanundio , showed positive allometric growth, whereas O. rubicundus exhibited a negative allometric growth pattern. The correlation between LWR and LLR was highly significant among all species ( p < 0.05). The study of Fulton's condition factor ( K c ) exhibited values below 1 in O. rubicundus , suggesting variation within the region. The values of the relative condition factor ( K n ) were within the range from 1.09 to 2.08, reflecting a favourable growth condition. These findings contribute to a deeper understanding of gobiid species, which is essential for their conservation and monitoring in the Indian Sundarbans.
