Sea Ranching and Artificial Reef Project

Sea Ranching and Artificial Reef Project

In a recent effort to bolster marine resources and foster sustainable fishing practices, twenty-thousand pompano (Trachinotus blochii) fingerlings were released off the coast of Vizhinjam, Kerala as part of an artificial reef and sea ranching project.

Sea Ranching and Artificial Reef Project

  • Objective: The primary goal is to restore fishery resources and support sustainable fishing through fingerling release. 
    • The project involves releasing one million pompano and cobia fingerlings at ten designated locations along the Thiruvananthapuram coastline as a follow up to the Artificial Reef Project.
  • Implementation: The initial batch of 20,000 pompano fingerlings was released approximately 1.5 nautical miles off Vizhinjam. 
  • Additionally, artificial reef modules funded under the Pradhan Mantri Matsya Sampada Yojana (PMMSY) have been deployed across 42 sites in 33 fishing villages within the district.
  • Funding and  Support: Supported by the National Fisheries Development Board (NFDB), the ₹3-crore project received approval in March and is managed by the State Fisheries Department with fingerlings cultivated at the Ayiramthengu Fish Farm.

About Sea Ranching

  • Sea Ranching/ Ocean Ranching is releasing fingerlings raised in controlled environments to replenish oceanic and lacustrine ecosystems, supporting long-term resource availability for fishing communities.
  • Purpose: Sea ranching is a government-led approach, focused on restoring fish populations and promoting marine sustainability. 
  • Species Cultivated: Varied species, including oysters, mussels, carp, trout, and tilapia, are grown in hatcheries and released into natural waters, allowing them to mature in their native habitats.
  • Technology Used: Modern ocean ranching relies on sophisticated breeding, rearing, and release technologies developed since the 1970s. These innovations help optimize species survival and integration into the wild.
  • Benefits:
    • Economic: Replenishes fish stocks, aiding the fishing industry and local economies.
    • Social: Provides sustainable income sources for fishing communities.
    • Ecological: Supports environmental protection and ecosystem regeneration.

About Artificial Reefs

  • Definition: Artificial reefs are human-made structures placed in aquatic environments to improve ecological conditions, providing habitats for marine species and enhancing fishery productivity.
  • Uses:
    • Restoration: Helps restore ecosystems, including coral reefs.
    • Fish Production: Increases fish stocks for small-scale fishers.
    • Wave Protection: Helps mitigate coastal erosion by absorbing wave energy.
    • Habitat Creation: Provides food, shelter, and breeding grounds for marine species.
    • Recreational Benefits: Supports eco-tourism, snorkeling, and recreational fisheries.
    • Bottom Trawling Restriction: Deters harmful bottom trawling near shorelines.
  • Materials: Reefs are constructed using durable materials like concrete, steel, and purpose-built modules in diverse shapes, such as triangular or floral designs.
  • Examples:
    • CMFRI Project (India): Aids fish availability while reducing costs for small-scale fishers.
    • Dubai Reefs: Utilizes 3D printing to build an extensive artificial reef network.
    • Pearl of Dubai: Features an artistic, city-themed reef near Dubai’s coast.

Significance of the Initiative

  • This combined sea ranching and artificial reef initiative not only supports marine biodiversity but also enhances local fisheries by increasing fish stocks and establishing stable marine habitats.
  • The project aligns with the government’s sustainable development goals, safeguarding marine life and empowering coastal communities through sustainable fishing practices.
