WebJan 1, 2024 · Studies on the anatomy of sulcus and outline morphometrics of the three population groups of Trichogaster lalia were carried out to examine the effects of anthropogenic stressors (dams and barrages) on the function-related morphological variability of the fish. Altogether 150 samples of the fish were procured from three … WebSep 3, 2024 · Fish morphometrics and condition. The 49 specimens varied from 19.3 to 33.0 cm TL (mean ± SD, 24.3 ± 2.2 cm) and from 39.9 to 203.8 g TW (83.3 ± 27.5 g). The potential models of length-weight relationships explained the size variability better for males (R 2 = 0.824) than for females (R 2 = 0.579) . These differences were caused by the …
