Abstract
In the present research work, 127 Labeo bata having diverse body size ranging from 8.20 to 16.00 cm total length collected from Head Panjnad, Pakistan were used for the analysis of some morphometrics, that is, length-weight and length-length relationships. Condition factor and their relationships to investigate growth external morphometric characters, that is, total length (TL), standard length (SL), fork length (FL), head length (HL), head width (HW), body girth (BG), dorsal fin length (DFL), dorsal fin base (DFB), pectoral fin length (PtFL), pectoral fin base (PtFB), pelvic fin length (PvFL), anal fin length (AFL), caudal fin length (CFL) and caudal fin width (CFW) showed highly significant correlation with both cases, that is, increasing total length and body weight. A significant positive relationship was found between condition factor (K) and body weight, while no significant correlation was found in condition factor and total length. Key words: Morphometry, length-weight, length-length relationship, condition factor, Labeo bata
Highlights
The use of morphometric measurements and meristics to identify and classify fish is common
In the present research work, 127 Labeo bata having diverse body size ranging from 8.20 to 16.00 cm total length collected from Head Panjnad, Pakistan were used for the analysis of some morphometrics, that is, length-weight and length-length relationships
Fin length and fin base values were measured as dorsal (DFL), pectoral (PtFL), pelvic (PvFL), anal (AFL) and caudal fin length (CFL) and these were measured as distance from anterior point of junction with body to the most anterior tip of the fin
