Im currently working on gut content analysis of some juveniles from seagrass bed in Seribu Archipelago, Indonesia. I found some difficulties as most diets were found in not complete part and perhaps broken. Thank you
First of all in your in your question you failed to specify whose juveniles you are working with. Still,based on the five photos, without considering the others attached -
The calanoid copepods are partially digested and the cyclopoid (may be Eucyclops)copepod is in its copepodite stage and also there exists a nematode worm.

I’m sorry to forget attaching the detailed description. Actually i’m identifying many juveniles. I’ll reupload the file with photos and fish which i analyzed.
Thank you for your respond.
So far the photographs that are attached confirmed the presence of copepoda, cladocera, and nematodes.
photo 1, 2 can be copepodite stage of copepoda but photo 6 can be a
rotifer
Photo 3 is a nematode (agree with Leonardo Cruz da Rosa) not polychaete (disagree with Abdul Ghaffar Siyal)
I agree that 7 is a chironomid and 9 a mite. Keep in mind that the nematode in #3 is more likely a parasite than a diet item.
Gregory Jensen Javed Mustaquim Leonardo Cruz da Rosa Jean François Cart thank you for your kind respond.
Firstly, i also agree the photo no. 7 may be Chironomid but i doubt it since it was found in the gut content of coastal fish species ? while chironomid mostly found in freswater species ?
for your information, i'm using 10x magnifier microscope so i think it's too big for chironomid.
