SALIENT ACHIEVEMENTS

Aquaculture Economics
  • Impact assessment of three major technology / policy interventions of ICAR-CIBA in the last two decades was conducted. The total economic impacts were assessed quantifying direct and indirect benefits using input output method. The estimated values were cumulated for the years of technology operation. The estimates were for WSSV kit 3340 crores (2002-2007), CIBASTIM 1290 crores (2014- 2017) and P. vannamei introduction 281752 crores (2009-2017).
  • Shrimp exporters of the world during 2016



  • Secondary data analysis indicated that In India, vannamei production has shown steady increase and reached 4.06 lakh tonnes (81 %) in 59116 ha of total area with CGR of 130.9% from 2009-10, 2015 -16, increasing the overall shrimp production to about 5 lakh MT. Whereas monodon area and production was 68846 ha and 81452 tonnes in 2015-16 with negative CGR of -2.48%.
  • Brackishwater Aquaculture sector need to be given more emphasis under the Government of India’s policy on “Doubling of Farmers Income”. Scientific production and management of shrimp and finfishes yields high income to the farmers within a short span of time, which are four-fold increase than the traditional practices. Production of shrimp species like white shrimp (Penaeus Vannamei; net return of Rs.7 lak/ha), milk fish (Chanos chanos; 2.40 lakh/ha), Asian Sea Bass (Lates calcarife; 4.00 lakh/ha), and Pearl Spot (Etroplus suratensis; 2 lakh/ha) would fetch higher income within short to medium time span. In addition prepared a document to Division of Fisheries on Doubling of Farmers Income through Brackishwater Aquaculture.
  • The compendium Braquastat 2017 has been brought out with information in brief about the various technical aspects of the brackishwater aquaculture sector. This publication consists of information about various aspects of aquaculture, viz., global scenario of brackishwater aquaculture, production and trade statistics, per capita availability of fish, utilization pattern of fish and so on. It also includes various boxes viz., CIBA milestones, CIBA technologies & their benefits, success stories of CIBA technologies, impact analysis for major CIBA technologies, economic loss due to major diseases and doubling of farmers income.
  • Secondary data on export rejection of aquaculture products indicated that

  • Aquaculture Extension
  • The technology package of three tier model of cage farming comprises of nursery rearing, pre-grow out and grow out phases in the open brackishwater was validated in partnership with fisher youth group and the NIOT at Vennangupattu village cluster, Kancheepuram district, Tamil Nadu. The technology is economically viable even in each phase. Stocking density adopted was 12 kg per/m3. CIBA’s Asian seabass seed and seebassplus feeds were used. A productivity of 460 kg was realised in one cycle. Two cycles of production can be taken in a year. The production cost was worked out to be Rs.190 per kg of fish and sale price was Rs.380 per kg with a B: C ratio of 2.0. A person spending 2 hrs per day in the nursery rearing, pre-grow out and grow out phases get a monthly income respectively Rs.6000, Rs.5000 and Rs.8500.
  • Vanami Shrimpapp is the first mobile app on shrimp farming and has been regularly followed by more than 7500 stakeholders (farmers and extension workers) across the globe (India, Indonesia, Vietnam, Brazil, Peru, Mexico, Ecuador, and USA). Recently the app has been updated with additional modules:

  • The content is applicable to vannamei farming in entire Southeast Asian countries and elsewhere in the tropical belts of the globe. The app has been appraised with a Google performance rating of 4.6 out of 5.0.





  • The need assessment for mobile connectivity regarding the day to day queries showed that the fish farmers approached CIBA regarding MGMG demonstration (39.08%), seabass fingerlings availability(6.03%),cage culture activities (2.01%),nursery rearing of seabass in hapas(2.87%),training details (9.48%),seabass seed rate (11.2%), milkfish seed availability(4.88%),seabass fry availability(16.37%) and Pearl spot larval rearing (8.04%). It is also noted that localization and native language of farmers are the concerns to be incorporated into the systems.
  • Frontline Extension Programme on seabass fingerlings 5000 numbers of < 2 cm size was provided to 5 Adidravida families in Keelar Kollai village of Kuvathur Panchayat, Tamil Nadu, for the rearing of the nursery in hapa as an alternative livelihood opportunity. The total duration of growth was 57 days and the fingerlings have grown up to 9.5 cm. The survival rate was 35.80%. The realized net income was Rs.27400. The results indicated that the technology is technically feasible and economically viable .


  • Frontline demonstration on Polyculture of milk fish, shrimp P.indicus and pearlspot farming and Orange chromide ornamental fish farming was conducted by CIBA during 2016-17. The beneficiaries were also trained to collect milk fish and other fishes from the wild and to stock them in this community pond with the water spread area of size of 1000 mt. sq. located in the backyard of 10 Irular community colony in Thiruvallur district in Tamil Nadu. was selected. On 4th July 2016, CIBA hatchery produced pearlspot fry (200 nos.), E. maculates fry (250 nos.), P.indicus seed (PL18) (2000 nos.) and milkfish collected from wild (2000 nos.) were stocked. Milkfish production was 92.5 kg and it was sold at Rs.120/kg in local market. From the total harvest an amount of Rs. 20,000/-was realized.
