Abstract
Food and feeding habits, reproduction and size at
first maturity of Photopectoralis bindus from Ratnagiri
coast are described, based on commercial catches
landed by trawls during 2013-2014. Copepods,
diatoms and cladocera form important food of the
species. The estimated length at first maturity is 93.5
mm. P. bindus is a fractional spawner and appears
to release the ova in at least two spawning acts
during the peak spawning season extending from
October to December. High gonado-somatic indices
correspond well with the peak spawning seasons
and females always have higher values. The
estimated fecundity ranged from 4377 to 10 449
