Biologi Reproduksi Ikan Guppy (Poecilia Reticulata) Di Waduk Fakultas Perikanan Dan Kelautan Universitas Riau Pekanbaru

Abstract
Poecilia reticulata is a type of small ornamental fish that lives in the dam located in the Riau
University campus. This study aims to understand the reproductive biology aspects of that fish,
especially sex ratio, gonadal developmental, fecundity, and egg diameter. The fish was sampled
2 times/week from March to May 2019. Total fish captured was 71 (44 males and 27 females).
The ratio between male and female was 1,23 : 1 Males was bigger than Females. In males, the
anal fin area modified into gonopodium, and there is a prominent genital papilla. The males
captured were in the 2st to 4th gonad maturity levels, while the female ovaries filled with eggs
that have developed embryos in several stages of development (superfetation). The fecundity of
the fish ranged from 10-60 eggs/fish. The eggs were divided into five groups based on embryo
development. The egg diameter in the 2nd stage was cream colored, no embryo inside, egg
diameter was 1.03-1.78 mm. The eggs in the 3nd stage were cream colored, 1.53-2.01 mm
diameter, embryo unclear. In the 4nd stage, the egg diameter was 2.01-2.25 mm, a small embryo
present in each egg. In the 5nd stage, the egg diameter was 2.29-2.48 mm, embryo well
developed, eyes and backbone are prominent and the eggs might be delivered soon.
Keywords: Ovoviviparous fish, gonopodium, Superfetation, egg development
