Tips for Fish Farming in India
Indian
fisheries and aquaculture is a crucial sector of food production,
providing nutritional security to the food basket, contributing to the agricultural
exports and engaging around 14 million people in different activities. With distinct
resources ranging from deep seas to lakes in the mountains and more than 10% of
global biodiversity in terms of fish and shellfish species since
independence, the country has shown consistency and sustained increments
in fish production. Constituting about 6.3% of the global fish production, the
sector contributes around 1.1% of the Gross Domestic Product
(GDP) and 5.15% of the agricultural GDP. The total number of fish
production of 10.1 million metric tonnes presently has nearby
65% contribution from the inland sector and nearly the same from culture
fisheries. The yearly carp seed production is to the tune of 25
billion and that of shrimp about 12 billion, with increasing diversification in
the recent past. Alongside food fish culture, ornamental fish culture and high-value fish farming are gaining importance in the recent past.
To design the best hydroponics system,
one must look at the host of factors contributing to plant growth, roughly
these are the environment, temperature, nutrient delivery and protection from
harmful agents.
Hydroponics farming in India looks to
the use of Greenhouses as an answer to manage these factors. Greenhouses are
huge structures built over tracts of flat land to accommodate the protected
farming techniques, that use climate control methods and such to grow seasonal
crops in unseasonal weather. In hydroponics, additional technology is used
known as water chillers as a cool root zone promotes aeration and root health.
Polycarbonate is also more durable but
it can be tough to work with due to its rigidity. The ultimate in greenhouse
material technology is the Glass greenhouses, both the most expensive and the
best to control temperature and climate. A Glass greenhouse would ultimately
require less frequent maintenance than any other type of greenhouse material.
A glass greenhouse would be ideal for doing hydroponics in Gurgaon or Delhi which
have very varying climates.
When looking at doing large scale hydroponics in India it is very important
to remember that we undergo usually intense summers followed by pleasant
winters. Heating is not a necessary concern except in extremely cold climates,
but these climate zones are restricted to a few pockets and usually, the market
for hydroponics is not present in these areas. However, it should not discourage
potential hydroponic farmers as the colder climates help them with growing
high-value exotics. These have high export and commercial value in urban areas.
Vertical Farming
Vertical farming is a technique of producing food and medicines on vertically
stacked layers, vertically inclined surfaces and/or integrated into other
structures (such as in a skyscraper, used warehouse, or shipping container)...
These facilities utilize the artificial control of light, environmental control
(humidity, temperature, gases...) and fertigation. Some
vertical farms use techniques that are similar to greenhouses, where natural sunlight can
be augmented with artificial lighting and metal reflectors.
Hydroponic systems can also be
lit by LEDs that mimic sunlight. The software can assure that all the plants get
the same amount of light, water, and nutrients. Proper management means that no
herbicides, pesticides are required
