Length–weight relationships and condition factors of five fish species from the coastal region of West Bengal, India

Abstract

AbstractThe present study presents the length–weight relationships of five brackish water fish species from the coastal region of West Bengal for which this relationship not known to the present time, including Stigmatogobius sadanundio, Brachygobius nunus, Microphis cuncalus, Butis melanostigma and Puntius vittatus. The slope (b) value of the regression ranges between 2.551 and 3.319, with high correlation values (r2 ≥ .943). The relative condition factor (Kn) was also calculated, being >1.0 for all species examined in the present study, indicating of the overall condition of the fish species.
