Aquaculture Production

1.0 Export production through aquaculture:

Export oriented aquaculture production continues to increase year over the year and the increased production contributed significantly for the sea food exports from the country.

Year 2017-18 proved to be another year of scaling new peak for Export oriented Aquaculture Production, continuing the growth trend set in from 2009-10(Fig. 1). The export oriented aquaculture production, including about 13,838 MT of fish and shellfish other than shrimp, reached about 7,05,600 MT, registering a 20% increase over the previous year production. In this, contribution of shrimp was 6,91,748 MT amounting to about 98% of the export oriented production. The changes in production trends have also reflected in the exports also.

Fig. 1. Trends in progress of aquaculture production of export oriented species

The spurt in shrimp production propelled by the exponential increase in vanamei production has resulted in steep rise in shrimp exports from India, both in terms of quantity and value (Fig. 2), during the last few years. Export earnings during the year 2013-14 and 2014-15 had shown more prominent increase compared to the increase in terms of quantity. This was due to a general increase in unit value realization during the years in comparison to the previous years.

1.1. Shrimp aquaculture production:

Increased production of the Pacific White shrimp (Litopenaeus vannamei) continued to propel India’s cultured shrimp. The production compiled based on the reports received from the field added up to 6, 91,748 MT during 2017-18, registering an increase of 20% over the production of 5, 70,637 MT recorded during the year 2016-17. The L vannamei production during the year was 6, 22,327 MT, which was 1, 21,030 MT more than the previous year production of 5, 01,297 MT, thus registering an increase of about 24%. Figure 1 also shows that the share of L. vannamei in total shrimp production has been on the increase and, during 2017-18 it reached 89.96 % of the total shrimp aquaculture production in the country. The composition of cultured shrimp production during the year is depicted in Fig 3 below.

The increase in L.vannamei production has helped to increase the overall productivity of shrimp farming. The trends in area under culture, production and productivity over the last 10 years are given in Fig. 4.

Among the other shrimps which contributed to aquaculture production during the year, the production of the native Tiger shrimp (Penaeus monodon) showed a marginal decline of 0.81 %, scampi and other shrimps (Penaeus indicus and other penaeid shrimps) registered marginal increases of 5.1 % and 4.11 % respectively from the previous years’ production

The growth trend in area under culture and production of L vannamei in various maritime states indicated that there was continuous expansion taking place in all the states, excepting the States of Karnataka and Maharashtra. The trend in the area utilization and production of L. vannamei shrimp in various maritime states of the country is given in Table 3. During the year 2017-18 the area under culture has increased to an extent of 6,244 ha (7.2 %) from that of the previous year. Average productivity showed an increase to 6.66 MT/Ha/Yr. from the previous year’s productivity of 4.5 MT/Ha/Yr. This increase in productivity can be attributed to increase in productivity in the state of Andhra Pradesh. Farms stocking at higher rates and harvesting smaller size shrimp has resulted in higher yield per ha per annum in the state.

1.3. Production of Other exportable varieties of fish and shellfish.

The field offices reported production of 13,615 MT of other diversified species, such as Crab, Sea bass, and Tilapia (GIFT) besides Pangassius production of about 26,300 MT of during the year under report. The production of diversified species of fish and shellfish for export is still in the early stages. Large scale development can be possible with the involvement of corporate bodies who can invest in setting up integrated units of exportable varieties of fish and shellfish including hatcheries, farms and processing plants. Details of production of diversified export oriented species are given in the table below:
