Final Assignment: Puntius binotatus (Common Barb)
Spesies: Puntius binotatus (Valenciennes, 1842)
So here it is another story from my final assignment. My other specimen from the field is Puntius binotatus. This small fish is a freshwater fish, benthopelagic, and usually live in tropical area with warm temperature about 24ºC to 26ºC. Based on the fact before, it's exactly like the place where I caught it.
The area was in Citarum river, I tried to find them in under the small cave which had slower stream speed. I also found them in the river arm, small stream that heading to the main river, under the bushes and roots that located in the verge of the stream.
This fish born in small size, with maximum size about 20 centimeters and their common length is about 10 centimeters. As I said before this fish occupied freshwater area in tropical zone, so they can be fin in Myanmar, Thailand, and Indonesia. They're able to live in 0 to 200 meters above sea level. To find them we must search into several spots, such as below waterfalls, isolated mountain streams, small pond in the middle of the field, or any other freshwater spot with relatively slow stream.
Their color may varies, they can be silvery gray to greenish, or even just gray.
They feed on zooplankton, insect larvae and some vascular plants. They usually stay where they born, they don't migrate except they're being moved by a large volume of water that come from heavy rain or any other possibilites such as human involvement such as changing the ground structure near their habitat.
This fish used as a feed in aquarium for larger fish, or even, in Indonesia, consumed by human as a side dishes. This fish also able to control the numbers or mosquito larvae to help human prevent the spreading of disease that vectored by mosquitos.
This are some of the specimens that I got in my first sampling attempt.
