25. — Thumpai valai (Tamil). 
Locality : Certain parts of Jaffna lagoon. 
Fish caught : Very small fish (Thumpai, Netthalai, &c.) 
and also immature fish. 
Description : A net similar to Paddu valai, but differs from 
it principally in the size of the mesh, which is very small. 
Dimensions: Length, 4 fathoms; height of mouth, 2^ 
feet ; depth of bag, 34 feet ; mesh, |- inch ; stakes, 
every 3 feet. 
Method of Use : This net is used for catching very small 
fish (Thumpai, Netthalai, &c.). In my notes I have suggested 
that this is a harmful type of net, as it undoubtedly catches 
immature fish.
