| Abstract | ||
| This survey was performed in order to investigation of parasites in different tissues of cultured shrimp and survey of intensity and incidence of these parasites in different tissues of shrimp. In this survey 145 shrimp belonged to Penaeus monodon and 97 shrimp belonged to P. indicus were reviewed. Epicommensal protozoa from gills and appendages by wet smear, stomach and hepatopancreas and intestine by stereomicroscope, crashed muscle and digested muscle and also, crashing of intestine for digestive protozoa were reviewed. The most intensity and incidence were belonged to Epistylis, Zoothamnium and Vorticella, respectively. In relation to metazoa parasites, there were no observation of worm parasites, such as trematodes, nematodes, cestodes and digestive protozoa such as gregarine among the cultured shrimp. All shrimp are susceptible to fouling by epicommensal protozoa. These organisms are naturally present on the bodies of cultured shrimp and their intensity and incidence can be related to the environmental condition. According to life cycle of metazoa and digestive protozoa (Johnson, 1989), absence of these parasites among cultured shrimp can be due to lack of intermediate hosts and consequently lack of completion of life cycle of these parasites in the cultured environments and consumption of prepared (inert) food. | ||
