Brown spot disease in Penaeus kerathurus eggs and larvae: a case report

Melicerthus kerathurus (Caramote prawn) is a very appreciated crustacean species, recently proposed as a species for restocking the natural population. The hatching and the early stages of larval development are the most delicate and generally more sensitive to the microbial attack. In this paper the authors reported an outbreak of brown spot disease among a wild broodstock of caramote prawn. Results showed that the etiological agent of disease was Vibrio alginolyticus that caused the disease in broodstock and in larvae and nauplii also, with 80 % of mortality rate. Accurate management protocols have been improved to achieve a good production results
