4.5. Galvanized iron jar hatchery
Unit 4 - Different types of fish hatcheries
4.5. Galvanized iron jar hatchery
-
This hatchery resembles Bhowmick’s glass jar hatchery except that the hatchery glass jars are replaced by galvanized iron jars.
-
Each jar has a cylindrical portion (48.5 cm long and 23.0 cm diameter ) and a top conical portion (19 cm long).
-
The jars are filled on an angle iron framework which also accommodates a galvanized iron conduct (10 cm wide and 10 cm high) to carry the hatchlings from the jars to the spawnery.
- The water flow rate is 1 L/min.
- The galvanized iron jar hatchery is cheaper than glass jar or polythene jar hatchery.
