When
can we reach 18?
India is a major maritime state
and an important aquaculture country in the world. India stands fourth in the
world fish production and producing 11.6 mt where 7.49 mt comes from the inland
sectors and marine sector contributing 4.11 mt. The annual export is around
1.14 mt from fish and shellfish with estimated earnings more than Rs.38,500
crores (MPEDA, 2017), accounting for 18% of the agricultural exports and over
3% of the total exports. Producing about 6.42% of the world's fish, India
trades to the extent of 3.5% in the global fish market.
Aquaculture is increasingly
becoming important, with an annual growth rate of over 6%. The country is the
second largest producer of fish through aquaculture in the world, next to
China. The annual per capita availability of fish (PAF) in the country is as
follows:
The total population of the
country as on 11 February 2018 it is 1.34 billion (Exactly it is 1349 860 549).
India is exporting 1.14 mt to other countries. So the total available fish in
India is 10.26 mt (10260, 000,000 kg) which includes non edible part and the
quantity of fish that goes for industrial purpose also.
PAF =
10260,000,000/1349 860 549 = 7.6 kg
Till date, many scientists have
taken only 50% of the population as fish eating numbers. In no statistics and mathematics,
these conveniences are not allowed. While calculating per capita income,
unemployed people and all kids are also taken into consideration. Similarly, if
we go by established and accepted norms, we need to consider entire population
for per capita calculation and it is 7.6 kg/person/anum
This is lower than the WHO
recommendation of 18-20 kg/person/annum. By considering 6% growth in fisheries
sector, it might take 20-22 years to reach the 18 kg/person/anum provided the
population remains constant. But the population is growing at the rate of 1.2%
per year. So, it might reach 1.5 billion by 2030. The finite resources remain
constant. Due to siltation, drought, encroachment, weed infestation, the water
spread area is not as the area mentioned in the records. On the other hand, new
areas are converted into fish ponds. These complex issues call for serious
intervention of the data management and scientific strategies to enhance fish
production in the existing resources.
In this context, the total
aquatic resources and the fish seed requirement of the country is calculated by
taking moderate stocking density. If the vast aquatic resources of the country
are put into use effectively for fish production using quality seed with right
size and right species composition, this 18 can be achieved much earlier. India
is already producing sufficient quantity of fish seeds. But due to unscientific
rearing management and transportation, significant quantity of fish seed is
lost every year.
To utilize all the aquatic resources
as suggested in the above table, the total seed requirement would be 6.67
billion (66,777,000,00) fish seeds. To
produce this quality fish seed by taking 25% survival from spawn to fingerling,
we need 26.68 billion spawn. The average production of all these waterbodies is
about 800-900 kg/ha. Through our right intervention, if the average production
is increased by 100 kg/ha, the per capita consumption is increases by 1.07
kg.
Aquaculture Version 8.0?
Indian aquaculture started with stocking wild seeds (version 1.0), later moved to stocking hatchery bred seed (Version 2.0) along with a manuring schedule (Version 3.0) which was natural food based. Slowly, farmers started feeding rice bran and ground nut cake (Version 4.0). With continued advancement in aquaculture technology growers began using aerators (Version 5.0) and use of sinking feed pellets (version 6.0). Extruded feeds are now added to Indian aquaculture (version 7.0) and now IPAT as Version 8.0.
Since scope for horizontal expansion of aquaculture is limited, farmers need to shift from 6.0 to 7.0 or 8.0 soon. The present rate of rice bran is Rs. 25-30/kg and Rs. 40-50 for groundnut cake. When their mixture (1:1) is given the cost of production of carps in semi intensive aquaculture will be Rs. 108/kg when Food Conversion Ratio (FCR) is taken at it best i.e. 3.0. Looking at the economics of the conventional feed, it is cheaper to go for commercial diets. Because of the scale of economy, feed companies are able to produce the feeds at reasonably cheaper than the conventional feeds.
Blue Revolution II:
Carp’s average production
in India is about 3.5 t/ha as against 10-20 t/ha in china, while Vannamei’s
production is about 8-12 t/ha against 40-60 t/ha in Vietnam. In India, the
average production of any fish/shrimp species is less than those in many countries;
these production levels are attainable even in India. Fragmentation of land,
low working capital, no diversification, lack of infrastructure and skilled man power, technological gaps, weak
extension, gaps in policies, poor support services from banks, developmental
agencies, non availability of inputs in farmer’s vicinity, high cost of inputs,
smartness of middleman, weak cold chain, disease problems, unorganized system among
others appear to have limited the higher production potential.
However, production
technology alone will offer the solutions for the above said problems. There
are many non technical issues which are playing a significant role in the
performance of the fisheries sector. The parameters which play a significant
role in enhancing fish production are as follows:
- Breed selection
- Feeds and feeding management
- Water quality
- Improved larval rearing facilities and Larval feeds
- Grading
- Seed transportation
- Stocking right size seeds in right quantity
- Stocking based on production potential of given waterbody
- Data management
