Compare Growth Rates: Of the four species, rank them by how quickly each reaches market size.
Pangasius hypophthalmus (striped catfish) grows fastest, reaching marketable size in just 6–8 months, which is why it's so popular in intensive aquaculture.
Catla and Rohu (Indian major carps) grow at a moderate pace, and Clarias batrachus, while hardy, is farmed less now and doesn't match Pangasius's growth speed.
