What is Aquaculture? Blog Image

Overview:

The Food and Agriculture Organization (FAO) of the United Nations has offered its technical expertise and knowledge to deal with the impact of climate change on the country’s aquaculture and the fishing community engaged with it.

About Aquaculture:

  • It is the propagation and husbandry of aquatic plants, animals, and other organisms for commercial, recreational, and scientific purposes.
  • Aquaculture is an approximate aquatic equivalent to agriculture—that is, the rearing of certain marine and freshwater organisms to supplement the natural supply.
  • This includes production for supplying other aquaculture operations, for providing food and industrial products, for stocking sport fisheries, for supplying aquatic bait animals, for stocking fee-fishing operations, for providing aquatic organisms for ornamental purposes, and for supplying feedstocks to the pharmaceutical and chemical industries.
  • Aquaculture has been in existence since at least 500 BC. However, only since the mid-20th century has it assumed commercial importance.
  • There are two main types of aquacultures—marine and freshwater. 
  • Aquaculture can happen all over the world: in coastal ocean waters, fresh water ponds and rivers, and even on land in tanks.
  • It is one of the fastest-growing forms of food production in the world. 
    • Globally, aquaculture already supplies more than half of all seafood consumed by humans.
  • More than 550 aquatic species are farmed via aquaculture.
    • The top fish species include carp, catfish, salmon, and tilapia; commonly farmed shellfish include shrimp, oysters, clams, mussels, and scallops.
    • Newer to marine farming are various species of seaweed, which total 27% of annual global aquaculture tonnage. 
  • Major Producers:
    • China is firmly at the top of the global aquaculture production, producing nearly 60% of farmed seafood.
    • Other leaders include Indonesia, India, and Vietnam.

Q1: What is the Food and Agriculture Organization (FAO)?

It is a specialized agency of the United Nations (UN) that leads international efforts to defeat hunger. It is the oldest permanent specialized agency of the UN, established in October 1945. Its mandate is to improve nutrition, increase agricultural productivity, raise the standard of living in rural populations, and contribute to global economic growth. The FAO coordinates the efforts of governments and technical agencies in programs for developing agriculture, forestry, fisheries, and land and water resources.

State of the World’s Children 2024 (SOWC-2024) Report Blog Image

Overview:

The world is facing an unprecedented crisis with nearly half of all children – about 1 billion – living in countries that face a high risk of climate and environmental hazards, the UNICEF’s State of the World’s Children 2024 (SOWC-2024) report, said recently.

About State of the World’s Children (SOWC) Report:

  • It is the annual flagship publication of the United Nations Children's Fund's (UNICEF’s).
  • Each SOWC report closely examines a key issue affecting children.
  • These have ranged from children with disabilities, conflict and war, child labour, urbanization, early childhood development, and much more, making it the most comprehensive analysis of global trends that impact children. 
  • The report includes supporting data and statistics.
  • Highlights of SOWC-2024:
    • This year, The State of the World’s Children report was launched on 20 November, celebrated globally as World Children’s Day–UNICEF’s annual day of action for and by children, with focus on ‘Listen to the Future,’ voices of children and young people on the world they want.
    • The report explores three megatrends that will profoundly impact children’s lives between now and 2050: demographics shifts, the climate and environmental crises, and frontier technologies.
    • The report projects that by 2050, the global child population will stabilize around 2.3 billion, with a significant shift in regional distributions. 
    • India, China, Nigeria, and Pakistan are expected to account for more than a third of the world’s child population by 2050.
    • India is estimated to have the largest share at 350 million, despite a decline of 106 million compared to today. 
    • Nearly one billion children worldwide face extreme vulnerability to climate and environmental hazards, with Indian children disproportionately affected.
    • According to the Children’s Climate Risk Index (CCRI), in 2021, India ranked 26th out of 163 ranked countries globally, with children particularly exposed to risks such as extreme heat, floods, droughts, and air pollution.
    • By 2050, as the report has cautioned, children, not only in India, but also worldwide, will face dramatically increased exposure to extreme climate and environmental hazards.
    • It predicts that nearly eight times more children will be exposed to extreme heat waves compared to the 2000s.
    • The digital divide remains stark. In 2024, over 95 percent of people in high-income countries are connected to the internet, compared to nearly 26 percent in low-income countries.

Q1: What is the United Nations Children's Fund's (UNICEF’s)?

The United Nations International Children’s Emergency Fund (UNICEF) was established in 1946, in the aftermath of World War II. Its mandate is to help children and young people whose lives and futures were at risk – no matter what role their country had played in the war. It works in over 190 countries and territories to protect the rights of every child. UNICEF's work is funded entirely through the voluntary support of millions of people around the world and our partners in government, civil society and the private sector.

What is Central Value Added Tax (CENVAT) Credit? Blog Image

Overview:

The Supreme Court recently gave a major fillip to telecom companies by allowing them to claim Central Value Added Tax (CENVAT) credit for the installation of mobile towers and peripherals like prefabricated buildings (PFBs), for which they pay excise duties.

About Central Value Added Tax (CENVAT) Credit:

  • CENVAT allows a manufacturer to utilise the credit of excise duty or additional duty paid for the procurement of input services to pay off the excise duty on his/her final productor output services
  • Under CENVAT, manufacturers get credit for the tax paid on raw materials, which they can later use to offset the excise duty they owe the tax department.
  • It was introduced as a modification to the previously functioning Modified Value Added Tax, or MODVAT.
  • During the course of the manufacture of final products, the raw materials travel through various stages of production, wherein a duty is levied on every value-added at each stage.
  • CENVAT, therefore, eliminates this double taxation, thereby simplifying taxation for manufacturers and consumers at large.
  • In 2004, the government established ‘The CENVAT Credit Rules’ in order to implement CENVAT across the country and offer Indian manufacturers of final products certain tax credits on the excise duty payable by them.
  • CENVAT credit refers to the set-off available to manufacturers if they utilise some specific inputs for manufacturing their products.
  • A manufacturer can claim CENVAT credit on the following cases:
    • Excise duty on a final product: For manufacturers and producers of final products.
    • Service tax on output services: For providers of taxable and exempted services.
    • Inputs and capital goods: If these goods are being partially processed.
  • Impact on Businesses:
    • It reduces the overall tax liability by allowing the offsetting of taxes paid on inputs against the final tax liability.
    • It promotes compliance as businesses can claim credit only if the input supplier has paid the tax to the government.
    • The availability of Cenvat Credit encourages businesses to invest in capital goods, as the tax paid on such goods can be claimed as credit. This incentivizes modernization and technological upgradation, leading to improved productivity and quality.

Q1: What is Excise Duty?

An excise or excise tax (sometimes called an excise duty) is a type of tax charged on goods produced within the country (as opposed to customs duties, charged on goods from outside the country). It is a tax on the production or sale of a good. This tax is now known as the Central Value Added Tax (CENVAT). It is mandatory to pay duty on all goods manufactured, unless exempted.

Candidatus Phytoplasma Blog Image

About Candidatus Phytoplasma:

  • It is a microbe with a cell wall lacking Mollicutes bacteria.
  • These bacteria thrive in the nutrient-rich phloem and sieve cells of plants.
  • Transmission: The transmission of these pathogens takes place primarily through phloem feeder insects (leafhoppers, plant-hoppers, psyllids, and dodders), which are known to infect many commercially valuable crops like Catharanthus, tobacco, maize, and grapevine.
  • The manifestations of the disease are disfigurement and virescence of the floral parts, giving a leafy appearance.

Key facts about Sesame

  • Sesame (Sesamum indicum L.) is the oldest indigenous oilseed crop, with the longest history of cultivation in India.
  • Sesame or gingelli is commonly known as til (Hindi, Punjabi, Assamese, Bengali, Marathi), tal (Gujarati), nuvvulu, manchi nuvvulu (Telugu), ellu (Tamil, Malayalam, Kannada).
  • It is a primordial oilseed crop since the remnants of sesame seeds were discovered at Harappa and Mohenjodaro.
  • Climate Requirement:
    • Sesame is grown in almost all the states in large or small areas. It can be cultivated up to the latitude of 1600m (India 1200 m).
    • Temperature: Normally the optimum temperature required during its life cycle is between 25-35 0C.
    • If the temperature is more than 40 0C with hot winds the oil content reduces.
    • Soil: Sesame can be grown on a wide range of soils, however well drained light to medium textured soils are preferred. It does best on sandy loams with adequate moisture.
    • Climate: Semi arid climate of Western India, Central, Eastern and Southern part of India including lower Himalayas.
    • Season : It is cultivated during Kharif in arid and semi-arid tropics and rabi/summer in cooler areas.
  • The crop is grown in almost all parts of the country. More than 85% production of sesame comes from West Bengal, Madhya Pradesh, Rajasthan, Uttar Pradesh, Gujarat, Andhra Pradesh and Telangana.
  • Uses: Sesame oil is excellent from a medicinal point of view. It contains antioxidants, and it is perfect for heart patients.

Q1: What is Bacteria?

These are microscopic single-celled prokaryotic organisms that play a crucial role in the ecosystem and have a significant impact on human health. Bacteria can be found all over the world, including the top of the mountains or the deeper trenches in the oceans.

Biofloc Technology and Recirculating Aquaculture Systems  Blog Image

Overview:

India's aquaculture sector has increasingly adopted Biofloc Technology (BFT) and Recirculating Aquaculture Systems (RAS).

About Biofloc Technology and Recirculating Aquaculture Systems:

  • Biofloc Technology is a closed tank-based fish farming approach which cleans the water in fish tanks by using beneficial bacteria.
  • Heterotrophic bacteria (commonly Bacillus, Pseudomonas, Nitrosomonas, Nitrobacter, Acinetobacter, and Alcaligenes) are used to convert organic waste (such as uneaten feed and fish waste) into microbial biomass, which can then be consumed by the fish or shrimp.
  • Advantages
    • This process keeps the water clean without needing to change it often and at the same time reduces the risk of disease as well in the fish. Water stays cleaner, hence farmers do not need to depend on external use of chemicals or antibiotics.
    • BFT also saves money on feed, as fish can get extra nutrients from the recycled waste, making it sustainable, cost-effective and environmentally friendly for fish farming.
    • The inbuilt aeration system to maintain adequate dissolved oxygen levels to promote microbial activity, along with mechanical filtration reduces chances of infection.
    • It is more suitable for small farmers with limited land as it can be established in a small area and even set up for backyard farming. However, it is associated with challenges, including high costs. 

What is Recirculating Aquaculture Systems?

  • It is also a closed-loop tank-based farming that recycles water after filtration.
  • RAS filters and cleans the water in the tank, removing waste and keeping it safe for the fish to live in.
  • It has automated set up of culture tanks with both mechanical and biological filtration units, and effectively prevents the entry of pathogens from external sources.
  • It requires the minimal interventions to assess the culture, water and disease monitoring, which allows for improved biosecurity. So, fish are less likely to get sick and need for disinfectants or antibiotics is thereby reduced.
  • The RAS approach also offers a controlled environment for factors like temperature, oxygen levels and cleanliness, ensuring optimal conditions for healthy fish growth.
  • It can be set up indoors or in areas without natural water sources, allowing fish to be raised closer to cities and where demand is high.

AroTrack Blog Image

Overview:

Recently, scientists at the Indian Institute of Technology Bombay (IIT Bombay) have developed a water-pollutant detecting device called ‘AroTrack’.

About AroTrack:

  • It accurately detects harmful aromatic xenobiotic pollutants such as phenol or benzene, xylenols.
  • It uses proteins typically found in bacteria living in heavily polluted environments to effectively identify multiple aromatic pollutants in water.
  • This protein undergoes a highly selective ATP hydrolysis chemical reaction if an aromatic compound is present in the sample.
  • This reaction is expressed with a change in the colour of the protein solution, which AroTrack can then detect.
  • AroTrack contains a light emitting diode [LED]-phototransistor assembly that shines a light of appropriate wavelength through the sample and detects how much is absorbed.
  • The key component of the device is a biosensing module called MopR - a sensitive sensor for detecting phenol.
  • The device also reliably worked in water temperatures up to 50 degrees Celsius and completed the tests in less than 30 minutes.
  • Significance: It's low cost, battery-operated nature, and portability can be ideal for rural and low-income settings that often lack resources and have difficulty accessing expensive laboratory tests.

Q1: What are Xenobiotics?

These are substances foreign to living systems and include drugs, pesticides, pollutants, carcinogens, volatile petrochemicals, food additives, and polluted working environments.
