Abstract:- The purpose of this study was to determine
the study of aspects of reproductive biology of
manggabai fish (Glossogobius giuris). The method used
is the observation method, where all fish are observed
directly in the field for some characteristics of gonad
maturity, while other observations are carried out in the
laboratory. The parameters measured and observed are
gonadal maturity level, gonadal maturity index, egg
diameter, and fecundity of manggabai fish. Manggabai
fish used during the study amounted to 50 heads
consisting of 25 males and 25 females with a body length
range 16.3 - 25.1 cm and body weight 26.66 - 48.24
grams. The results showed that the largest manggabai
fish TKG was obtained at TKG I which was 32% (male)
and females at TKG III were 36%. TKG greatly affects
the IKG value, both in male and female fish. The highest
IKG value of manggabai fish for female fish is in TKG
IV with IKG values of 6.272% and for male fish 0.574%.
Manggabai fish egg diameter reaches a length of 0.30 -
0.68 mm, width 0.07 - 0.10 mm with a weight of 0.08 mm.
the fecundity of manggabai fish with gonad 4.09gr
weight reached 3,172 eggs while gonad weight was 0.35gr
with a range of 1,196 eggs.
