Speaker: Dr N. P. Sahu
During the last two decades aquaculture sector has witnessed a consistent growth rate of 6% with a significant increase in foreign exchange earnings of more than Rs 47,000 crore in 2018-19 and occupied the largest component among the agricultural export of the country. Besides, this sector contributes 5.23% of the agricultural GDP of the country and provides livelihood to around 14.5 million people. About 12.8% of the total animal protein consumed in India comes from freshwater fish only. With the exclusion of milk, fish is the largest contributor to non-vegetarian protein among Indians. When agriculture production has almost been static, the fisheries and aquaculture sector appears to be the sunrise sector to support the economy of the country. Total fish production has reached 13.7 million tons (MT) in 2018-19, where about 50% of total production is contributed by aquaculture only. It is estimated that we have to produce two-third of total fish production from aquaculture by 2030. Our fish production has increased from a mere 0.70 MT in 1950 to 13.7 MT in 2019 i.e. 20 fold increase during the last 70 years, only due to technological development and support. From this production level further increase is only possible through innovative technological intervention, which should be easily accessible by the farmers. As a major chunk of production comes from the marginal farmers for which they need to be technologically supported at affordable prices.
From traditional to high-tech aquaculture, we have to make a balance by supporting the farmers with low-cost gadgets for accelerating the farming operation. Usage of technology in operation management will ensure cost reduction, improve the delivery process & product quality, thereby creating value for customers. Aquaculture operation involves a series of activities including pond preparation, seed production & hatchery management, culture practices, feeding management, health management, post-harvest processing, which are mostly manually operated. Though biologists have some limitations for the engineering intervention for some routine aquaculture activities, but bio-engineering approach may change the total landscape of aquaculture. There is a lot of scope for technological intervention in the area of seed production, hatchery management, water quality monitoring, feeding management, and value-added fish products, where small devices can be developed, which will help the farmer in a big way. Some thought-provoking ideas will be discussed during the seminar. The young engineer’s mind may bubble up with some creative thought, paving the way for the development of some new prototypes or devices for improving the aquaculture practices in the country.
