Özet
In this study, it was aimed to determine the larval ontogeny of Paraphanius mento, (Heckel, 1843), which is
distributed in Nemrut Crater Lake (Bitlis-Turkey). However, embryonic and
larval development stages were evaluated microscopically and histologically. In
the samplings carried out monthly between September 2018 and October 2019, brood
sized fishes were caught using an electroshock device and their production was
carried out after appropriate adaptations. Filamentous and sticky fertilized eggs has a diameter of 1.251±0.316 mm
with the inclusion of 8-12 oil droplets have started to hatch approximately 11
days after spawning at 23.5 °C. It was determined that newly hatched larvae
have a total length of around 3.695±0.225 mm (n:20), have started exogenous
feeding at 3 day after hatching and started to take particulate baits at the end
of 10 day after hatching. Digestive tract differentiation, hepatopancreas,
digestive tubes and gill arches formations were examined by taking histological
sections in early life stages.
