Stress level of vaname shrimp (Litopenaeus Vannamei) with infested ciliata pathogens after open wet transportation

Abstract

Vaname shrimp (Litopenaeus vannamei) is one of the leading fishery commodities in Indonesia. The unbalanced interaction between the environment, host, and pathogen causes the shrimp’s body defense to decrease and it is easy for parasites to infest and cause disease. This study aimed to determine the correlation between stress levels and the degree of ectoparasite infestation in vaname shrimp which was infested with pathogenic ciliates prior to open wet system transportation. This research uses survey method. Sampling of vaname shrimp at IBAP Lamongan. The parameters observed were blood glucose levels and the degree of infestation. The results of the ectoparasite examination showed that the ectoparasites that infested vaname shrimp had the degree of infestation in the category of very mild to moderate infestation. The number of vaname shrimp with a very light category is 4, the category of light infestation degree is 22, the number of vaname shrimp with a moderate level of infestation category is 24. There is a correlation between blood glucose levels and the level of infestation of ectoparasites which have a very high power. Thus, an increase in blood glucose levels will be followed by an increase in the rate of ectoparasite infestation.
