Scholarcy highlights

  • India is the second largest fish producing country in the world with production of 12.6 million tonnes in 2017–18, and Indian major carps contribute bulk of this fish production
  • The survival rate of catla during larval rearing is normally lower than the other IMCs i.e rohu Labeo rohita, and mrigal Cirrhinus mrigala
  • The results revealed that immune genes IL-1β, C3, IgM and IgZ were detected in the unfertilized eggs indicating their maternal inheritance
  • Study of tissue distribution pattern of the genes indicated that innate immune genes were ubiquitously expressed in different tissues with varying degree of expression, whereas adaptive immune genes were predominantly expressed in lymphoid organs of catla
  • The information generated will improve knowledge on the maturation of the immune system in catla and will aid in deciding the appropriate age for vaccination in this teleost species
