    Impact of Pacific White Shrimp (Litopenaeus vannamei) on Shrimp Production and Seafood Processing in Andhra Pradesh
    (Society of Fisheries Technologists (India), Cochin, India, 2015) Ashok, A.; Murthy, L.N.; Rao, B.M.; Debbarma, J.; Prasad, M.M.; Geethalakshmi, V.; Gopal, N.
    Introduction of new shrimp species Litopenaeus vannamei has brought a sea change in Indian shrimp production and processing industry. Andhra Pradesh is a leading state in cultured shrimp production and the present study investigates the changing trends in cultured shrimp production and its impact on seafood processing of the State. Results of the study showed that 83.6% of the cultured shrimp production in Andhra Pradesh was attributed to L. vannamei. With the increase in production, structural changes became pre-requisite for seafood processing firms and they have incorporated changes such as establishment of additional plants, increasing the capacity utilization of existing plants and installation of more efficient equipments. There was an increase of 37.12% in installed capacity and 53.1% increase in capacity utilization of shrimp processing plants due to increased shrimp production. Spillover effects were visible; employment opportunities and income of the employees increased. Strict implementation of scientific farming techniques and quality management are vital to sustain growth of the industry.

    Institutional development and efficiency of fishermen cooperatives in marine fisheries: a case study from Kerala
    (Society of Fishery Technologists (India), 2018) Jeyanthi, P.; Chandrasekar, V.; Ashok, A.; Nair, V.R.; Thomas, J.; Jos, K.D.; Gopal, N.
    Fishermen co-operatives have played a significant role in improving the livelihood of millions of fishermen. The extended co-operative services and efficiency of co-operatives over the years make the co-operatives effective. This paper presents the institutional development and efficiency of two fishermen co-operative societies viz., Njarakkal (Society I) and Manassery (Society II) in Ernakulam district, Kerala. It was revealed that there were spatial and temporal differences in institutional development between two societies while delivering co-operative services. From the results of Data Envelopment Analysis (DEA), it was found that the mean technical efficiencies estimated using Variable Returns to Scale (VRS) were 96 and 87% in Society I in and Society II respectively. The scale efficiency revealed that the Society II is operating at sub-optimal scale size than Society I. The amount of loan disbursed and repayment, income from fish marketing services were the factors responsible for the efficiency of co-operatives.
