During the examination of gills, I've been seeing the presence of eggs however it is not yet identified since I can't find any studies that have the same result. The situation of my sampling site is that their comfort room is not properly built the feces will directly go down into the water. Is it possible to detect an egg in the parasitological examination of freshwater shrimp? Can you recommend me any studies?
Wherever plants or animals are domesticated and farmed, diseases and parasites are sure to be found. A number of parasites on freshwater aquarium shrimps are becoming more prevalent, apparently through the commercial aquaculture of several species—most notably those of the genus Neocaridina. The most common external parasites are found on the animals’ surfaces and appendages. These infestations probably rarely cause mortality in the wild, but under the stressful conditions often found in densely stocked aquaculture ponds and tanks they can get out of hand and negatively affect mobility, molting, growth, and function. Breeding and feeding may stop, and mortality may result. High infestation of the gills, as found with peritrich ciliates, can affect respiration and may be fatal. Parasites are easily transmitted between species, so it is important to promptly treat any affected specimens, quarantine new shrimps, and perhaps give all new animals a welcoming dip.

It is possible for eggs of certain parasites to be found when examining freshwater shrimp for parasites. Fasciola, a type of flatworm that can infect the liver of freshwater and marine fish and invertebrates, is one example of a parasite that can produce eggs that can be found when examining shrimp.
Fasciola eggs are small (about 50-60 micrometers in diameter) and oval-shaped, with a thick, smooth outer shell. They can be found in the liver or other internal organs of infected shrimp, as well as in the feces of infected animals.
Other parasites that can infect freshwater shrimp and produce eggs that may be found during an examination include nematodes (roundworms) and trematodes (flukes). These parasites can infect the digestive system, gills, or other organs of shrimp, and their eggs may be found in the feces or other body fluids of infected animals.
It is important to note that the presence of eggs does not necessarily mean that the shrimp is actively infected with the parasite. Some parasites have complex life cycles that involve intermediate hosts, and the eggs may be present in the shrimp as a result of its exposure to the parasite in the environment, rather than as a result of active infection.
