Abstract:

Pacific white shrimp, Penaeus vannamei is the most extensively farmed crustacean species in the world as well India.In India, Andhra Pradesh state is occupying first place in culture production of vannamei shrimp. In recent years, P. vannamei faming in Andhra Pradesh is being encountered with multiple diseases such as running mortality syndrome (RMS), white spot syndrome virus (WSSV), white faeces/ white gut syndrome and severe retarded growth due a microsporedian, Enterocytozoon hepatopenaei (EHP) infection causing catastrophic influence on economy. Besides these diseases, cultured P. vannamei in Andhra Pradesh is being affected with soldier cap disorder with a clinical symptom of carapace folding out from the gill region at both sides, leading to moulting problem and poor growth rate in shrimp. In this connection, a study was conducted for a period of eight months from March 2017 to October 2017 in vannamei culture ponds of Nellore, Prakasam, Krishna and West Godavari districts of Andhra Pradesh state to analyze the possible causes of soldier cap in vannamei with respect to various pond management practices. The prevalence of soldier cap in P. vannamei noticed was 20%, 40%, 30% and 30% in Nellore, Prakasam, Krishna and West Godavari districts respectively. A co-relation was observed between stocking density, pond water quality parameters and soldier cap disorder. This study represents the first record on the emergence of soldier cap disorder in P. vannamei.
