The utility of Visible Implant (VI) tags for marking tropical river fish.
An experiment to assess the utility of VI tags for marking five species of tropical river fish was conducted in culture ponds at the Bangladesh Agricultural University, Mymensingh between March and July, 1995. The sub-project confirmed that VI tags could be used to measure the growth rates of certain species of fish, having no significant effects on tagged specimens. Tag loss rates, however, were extremely high for the most important and smallest key species Puntius sophore and Glossogobius giurus. Following this result, an alternative methodology was developed to determine the growth component of the Bangladesh floodplain production model.
