Abstract: The morphology of fishes is the primary source of information for taxonomic and evolutionary studies. The present work aims to study the length-length relationship and meristic characteristics of two indigenous fresh water species, Dayella malabarica and Hyporhamphus limbatus. Both fishes are of great demand as food fish as well as in ornamental fish industry. Fish samples were collected by the fisherman from Kole wetlands of Thrissur district during the month of October 2013. 10 morphometric and 6 meristic counts were recorded from a total of 60 specimens. Dayella malabarica specimens ranging from 4.7 to 6.6 cm Total Length and Hyporhamphus limbatus specimens ranging from 7.4 cm to 12 cm Total Length were used for the morphometric and meristic studies. Fish length measurements form the important resource for stock assessment and management including evaluation of population age structure and biomass for harvest regulations and habitat protection. Hence forth the present study helped in revealing more about stock for conducting sustainable fisheries in ornamental fish industry.
