In this study, the effect of Lemna minor on the lenght, weight and puberty of Pseudemys

scripta elegans was investigated. For this reason, the Lemna samples were collected from

three different parts of Kütahya Province and dried in the laboratuary. The turtles, in first

aquarium were fed with only L. minor (Group I). The second ones were intensively fed

with special feed (Group II) which brought from petshop. The third ones were restrictively

fed with the feed (Group III). The last group was fed with special feed and L. minor at

alternate days (Group IV). By this way, totally 80 turtles were used. As a result it was

determined that, the turtles, fed by L. minor + special feed were heavier that the others.

Pseudemys scripta elegans’IN AKVARYUM ORTAMINDA Lemna minor L. ile BESLEME İMKANLARI ÜZERİNE BİR ARAŞTIRMA

Öz

Bu çalışmada, Lemna minor bitkisinin Pseudemys scripta elegans’ın boy, ağırlık ve cinsi

olgunluğuna olan etkisi araştırılmıştır. Bu amaçla, Kütahya ilinin farklı üç bölgesinden

toplanan L. minor bitkileri kullanılmıştır. Toplam dört farklı akvaryumdan; birinci

akvaryumdaki kaplumbağalar sadece L. minor (Grup I) ile, ikinci akvaryumdaki

kaplumbağalar özel yem ile yoğun besleme (Grup II), üçüncü akvaryumdaki kaplumbağalar

az miktarda özel yem (Grup III) ve dördüncü akvaryumdaki kaplumbağalar ise özel yem +

L. minor (Grup IV) ile iki gün ara ile beslenmiştir. Bu şekilde dört farklı akvaryumda 20

şer kaplumbağadan toplam 80 kaplumbağa kullanılmıştır. Yapılan çalışma sonucunda, L.

minor + özel yem ile beslenen kaplumbağaların ağırlıklarının diğer gruplara göre daha fazla

arttığı tespit edilmiştir.
