#5713 Irrigation fields supplied by Sungai Wirolegi

Sponsored by

Indonesia, East Java, Jember

Biotope of rice field irrigation, precisely in the rice field irrigation of Ajung Village, Jember Regency, East Java.

I started this research with my friends on December 2, 2021. First we checked the plants around and underwater, then we explored rice fields irrigation channels with clear water in the dry season.

I was inspired to create an underwater ecosystem that is similar to the habitat, where I found such fishes as Rasbora argyrotaenia and Gambusia affinis.
