ARMOURED SAILFIN CATFISH

ARMOURED SAILFIN CATFISH

NEWS – CSIR-Centre for Cellular and Molecular Biology (CCMB) scientists have found out that the armoured sailfin catfish has spread to 60% in the water bodies of Eastern Ghats, damaging the fishing nets and the eco-system

ARMOURED SAILFIN CATFISH

  • Commonly known as Rakashior devil fish
  • Scientific name: Pterygoplichthys
  • Classified as an invasive species
  • Unique Characteristics – Diverse diet and ability to endure low oxygen levels + Capable of moving on land with powerful fins
  • Initially introduced for unique appearance and algae-cleaning ability + One of six invasive species introduced for ornamental fish trade
  • Notable Features – Lack of commercial value and sharp spines + Poses threats to fishing nets and fishermen’s safety
  • Impact on Biodiversity – Voracious consumption of native fish species + Endangers delicate aquatic ecosystem
  • Environmental DNA (eDNA) – Environmental DNA (eDNA) is DNA shed by all organisms into their surroundings through natural processes during their lifetime or after death. It originates from cellular material shed by organisms (via the skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods.
