Extensive fishing off the Coromandel coast could be forcing the great seahorse to migrate laboriously toward Odisha.

There are 46 species of seahorses reported worldwide. The coastal ecosystems of India house nine out of 12 species found in the Indo-Pacific, one of the hotspots of seahorse populations that are distributed across diverse ecosystems such as seagrass, mangroves, macroalgal beds, and coral reefs. 

These nine species are distributed along the coasts of eight States and five Union Territories from Gujarat to Odisha, apart from Lakshadweep and the Andaman and Nicobar Islands.

The population of the great seahorse, which is among the eight species tagged ‘vulnerable’, is declining due to its overexploitation for traditional Chinese medicines and as ornamental fish, combined with general destructive fishing and fisheries bycatch, the study said.

Seahorses are poor swimmers but migrate by rafting — clinging to floating substrata such as macroalgae or plastic debris for dispersal by ocean currents – to new habitats for successful maintenance of their population. 

The species is abundant off the Coromandel coast (Andhra Pradesh and Tamil Nadu) but is under extensive fishing pressure, with 13 million individuals caught per year, the study said.

Radio-frequency identification (RFID) is a technology that uses radio waves to automatically identify various tagged objects. Radio Frequency Identification (RFID) is a wireless tracking method that uses tags and readers to track objects. Transponder, receiver, and transmitter are the three components of an RFID system.

The RFID reader continually sends radio waves of a specific frequency in RFID system. If the object to which the RFID tag is attached is within the range of the radio waves, it provides feedback to the RFID reader, which then identifies the object based on the feedback.

What are the different kinds of RFID?

• Passive tags, semi-passive tags, and active tags are the three types of RFID tags that are commercially available.
• There is no power supply for passive tags. They acquire their power from the readers’ incoming radio waves.
• Semi-passive tags comprise an internal circuit with a power source, but rely on the radio waves received from the reader to transmit the response.
• The internal circuit of active tags is powered by a power source.
• Passive RFID tags do not have a battery and are powered by the reader.
• Batteries are being used to power active RFID tags. It also utilises its own power supply to send the response to the reader.
• The Low Frequency, High Frequency, and Ultra-High Frequency bands are used by RFID systems.

RFID uses radio waves to communicate data from RFID chips to readers that do not require line of sight in order to obtain the data, whereas barcodes use light to read the black-and-white pattern printed on the sticky tag. An RFID tag can communicate with a powered reader even when the tag is not powered.

Importance of Fiscal Policy in India:

• In a country like India, fiscal policy plays a key role in elevating the rate of capital formation both in the public and private sectors.
• Through taxation, the fiscal policy helps mobilise considerable amount of resources for financing its numerous projects.
• Fiscal policy also helps in providing stimulus to elevate the savings rate.
• The fiscal policy gives adequate incentives to the private sector to expand its activities.
• Fiscal policy aims to minimise the imbalance in the dispersal of income and wealth.
