1.4.1. Egg, Fry and fingerling collection
Unit 1 - Fish seed resources and natural breeding of finfishes
2.1. Egg collection
- Large scale egg collection is possible only where locations of the breeding grounds are known and are easily accessible.
- Eggs are collected from one or two feet deep water by disturbing the bottom and scooping them with a ‘gamcha’, a rectangular spawn collecting net.
- Generally, large scale egg collection is not practiced in rivers.
Fry and fingerling collection
