Much shrimp

I went to the field and did a survey on the canal. I was able to catch so much shrimp. They were very very crowded in one place. This density is more than 100 individual par 1 swept.

I found interest things when I was separating the sample. Shrimps were gathering around the mud snail and Kawanina.

It may be Snails has or wearing a feed for shrimps. According to our lab study, Mud snail can produce feed ownself by microbes such as algae inside the body. Further in our canal survey in winter, we knew snails and shrimp s were living together with the same environment. So they could be an interesting relationship.
