  • I never knew fish could be tattooed so a little online research came up with the following http://www.dgukenvis.nic.in/news03-47.htm

    TUTICORIN Sept. 17. For the first time, the Fisheries College and Research Institute (FCRI) here has come across a ray fish with peculiar markings, probably by acquired by tattooing done by researchers or scientists. The tattooed fish was caught in the trawl net of a fisherman 30 km south of the Tuticorin coast at a depth of 160 metres recently...


    ...The left side of the dorsal region of the fish is marked with number `3', while the right side is marked with a letter `S'. The fish measures 47.7 cm in length and weighs 500 gms. Experts at the FCRI say that the marking by tattooing is usually done by scientists in fisheries research institutes to study the growth, food habits, reproduction, migration pattern and racial studies of the species. Since tattooing technique is widely done by research institutes abroad, the FCRI has written to South African, Sri Lankan, Australian, Singapore and Malaysian High Commissions in New Delhi to find out whether any leading fisheries research institutes in those countries had tattooed the fish for biological or migratory investigations...


    ...According to V. K. Venkatramani, Professor, Department of Fisheries Biology and Capture Fisheries, FCRI, tattooing is usually done on juvenile fishes and left in big tanks till the tattooed part is healed. After healing, the fish would be left in open seas to study its migration or biological features. Experts say tattooing is done on a large number of specimen of a particular species. Once the tattooing is done, information is passed on to other fisheries research institutes. Tattooing is considered to be the best technique since it is harmless and the dye mark would be retained permanently on the external body of the fish.
