Length–weight relationship of seven finfish species from Mandovi‐Zuari estuarine system, Goa, India

The length–weight relationships for seven finfish species belonging to 7 different families were estimated from Mandovi–Zuari estuarine system, Goa, India. Fish samples were collected from commercial boats operating surface and bottom set gillnets (length: 100–400 m, mesh size: 30–86 mm) from January 2017 to February 2018. The values of exponent b, in the length‐weight relationship, varied between 2.08 (Secutor insidiator) and 3.16 (Nuchequula blochii), with a mean value of 2.74 for all the species. Similarly, a value varied from 0.008 (Opisthopterus tardoore and Nuchequula blochii) to 0.05 (Caranx heberi) and significant r2 values ranging from 0.94 to 0.99 were obtained. The study has also established LWR of Chelon planiceps and Opisthopterus tardoore for which the previous records are not available.
