Abstract
Fluctuating asymmetry (FA) quantitatively determines the response of Glossogobius giuris to disturbed waters of Laguna de Bay. the morphometric, meristic, and plastic character measurements of gobies and effects of sites (Pila; Bay; Calamaba) and collection periods (Dry season-may and June; Wet season-august and September) were statistically analyzed. High percentage of correlated, direct relationships of characters was present in males, with plastic characters as major determinants of well-proportioned bodies. Females exhibit fluctuating asymmetry with low percentages of correlated, linear meristic and plastic characters. Regardless of sex, water condition in Calamba favored the growth of symmetrical meristic and plastic characters while in Pila, symmetrical morphometric growths of females were favored. Dry season promoted the maintenance of symmetical morphometric characters. Negative allometrism was found for the control and experimental gobies as evidenced by regression lines of length-weight of each group with a slope of b<3 (i.e., experimental : Male-2.57 and female-2.66; control: male-2.19 and female-2.34). Overall results indicate higher symmetry of characters for males than females which signify that lake waters of South bay of Laguna de Bay is not extremely limiting for the aquatic life in it such as G. giuris.
