Biometric characters of freshwater fish Securicula gora (Hamilton, 1822) From Meghadrigedda Reservoir, Visakhapatnam, Andhra Pradesh, India

Abstract

Securicula gora is a commercially important SIS (small indigenous species) fish of India. Biometric characters include both morphometric and meristic characters. Morphometric characters have been commonly used in fisheries biology as powerful tools for measuring discreteness and relationships among various taxonomic categories (Quilang et al., 2007) [13] . In the present study 25 fish samples of Securicula gora of variable sizes ranging from 13.4-16.8 mm in total length (TL) were sampled from Meghadrigedda Reservoir, Visakhapatnam. These specimens were allowed to measure various morphometric and meristic characters. The minimum and maximum range, mean, standard deviation, percentage of various parameters in total length were estimated.
