Abstract: Shrimp aquaculture especially Litopenaeus vannamei farming in India is reporting promising growth rate for the past decade and more than 14 million people were depending on this sector. The present study was conducted at L. vannamei cultured ponds, located at various coastal districts of Andhra Pradesh state, India, where vannamei farming was practicing at commercial level in semi intensive systems of aquaculture. The Andhra Pradesh state is the largest vannamei producer amongst the shrimp farming states of India contributing 2.31 lakh tonnes (70% of total Indian exports). The present study was conducted to evaluate constraints faced by the vannamei shrimp farmers in Andhra Pradesh. This study was conducted during the year 2014-15, in various districts of reorganized Andhra Pradesh state. A total of 3 districts were selected out of 13 districts of newly formed Andhra Pradesh state for the present study and a total of 180 vannamei farmers were selected both randomly and purposively and 60 vannamei farmers were selected from each district. The study was conducted based on personal interview schedule aided with well structured and pre-tested questionnaire consisting of 11 items of constraints such as seed, feed, diseases, management aspects, inputs, harvest, labour related, extension activities, infrastructure, marketing and miscellaneous constraints. Garrett’s ranking technique was employed for allotment of ranking to the various constraints. The data was analyzed using frequency and percentages. The results showed that out of the total farmer’s surveyed, seed constraint (rank-1) was opted as the major constraint, followed by other constraints such as labour constraint (rank-2), disease constraint (rank-3), feed constraint (rank-4), marketing constraint (rank-5), harvest constraint (rank-6), infrastructure constraint (rank-7), management constraint (rank-8), Miscellaneous constraints (ranking-9), extension constraint (rank-10) and input constraint (rank-11). The results were reflecting the existing scenario of L. vannamei culture in the study area. Irrespective of the ranking of the various constraints, majority of the constraints were the reasons behind the setback of vannamei crop failure. The study conclude that the regulating agencies such as MPEDA of GOI to take appropriate remedial measures to combat the identified constraints of the present study.
