Abstract
Length-weight relationship (LWRs) of two goat fish species of family Mullidae (Teleostei: Perciformes), namely Cinnabar goatfish, Parupeneus heptacanthus (Lacepède, 1802) and Yellowstripe goatfish, Upeneus moluccensis (Bleeker, 1855) was studied from major fishing harbor along the Tuticorin (Lat. 8°47? 26? N, Long. 78°10? 07? E) coast of Gulf of Mannar were described in this paper. A fortnightly mode of collection was done at monthly from June 2016 to November 2017 from trawl landings operated along the Tuticorin waters. The present study estimated b value ranges from 2.923 to 3.223 for the two species. The results pointed out that P.heptacanthus and U.moluccensis species has shown negative allometric growth pattern and positive allometric growth pattern respectively. Lengthweight relationship showed good fit with r 2 values varying from 0.955 to 0.985. In addition to information on LWR, new maximum length range of U.moluccensis species was reported.
