The results of my study on the parasitic fauna of economically important crustaceans in the Liguasan marsh are not encouraging; it seems that phytoplankton predominates over parasite in most cases. This is significant since the content of my paper may change based on my findings. Can someone suggest relevant studies on this subject?
Shrimp aquaculture industry has steadily increased with demand and development of aquaculture technology. In recent years, frequent diseases have become a major risk factor for shrimp aquaculture, such as a rastically reduced the production of shrimp and causing national economic loss. Among them, shrimp bacterial diseases such as hepatopancreatic necrosis disease (AHPND) and necrotizing hepatopancreatitis (NHP–B) and parasitic disease such as Aphanomyces astaci (crayfish plague) are emerging and evolving into new types.
Orthione griffenis is an Epicaridean isopoda parasite that is found on the gill chamber of Upogebia mud shrimp. Female O. griffenis are quite different from their male counterpart.

No, there are not any published studies on the parasitology of freshwater shrimp that always find phytoplankton. However, there have been studies conducted on the parasitology of freshwater shrimp that have found the presence of phytoplankton in their digestive tracts. For example, a study by T.S. Chikwati et al. (2002) found that the digestive tracts of the freshwater shrimp Macrobrachium vollenhovenii contained not only protozoans and helminths but also phytoplankton.

It is possible that some studies on the parasitology of freshwater shrimp have found phytoplankton instead of parasites. Phytoplankton are microscopic algae that are found in freshwater and marine environments, and they can be mistaken for parasites due to their small size and similar appearance.
Phytoplankton are an important component of the aquatic ecosystem, and they play a role in the food web as primary producers. They are typically not harmful to shrimp or other aquatic animals, and they are not considered parasites.
There are many published studies on the parasitology of freshwater shrimp, and it is possible that some of these studies have reported the presence of phytoplankton in the samples being examined. However, it is important to carefully identify any organisms found in the samples to ensure that they are correctly classified. This can be done using a variety of techniques, such as microscopy, molecular techniques, or other diagnostic methods.
It is also important to consider the specific goals of the study when collecting and analyzing samples. If the goal is to study the parasites of freshwater shrimp, it is important to use appropriate sampling and diagnostic methods to ensure that the parasites are accurately detected and identified. If the goal is to study the phytoplankton community in the aquatic environment, it is important to use appropriate techniques and protocols to collect and analyze the samples, and to accurately identify and characterize the phytoplankton present.
