Conservation centers often release juveniles once they reach sizes less likely to be eaten by predators.
Gharial hatchlings emerge at roughly 30 to 40 centimeters in length. In favorable conditions with adequate fish supply, juveniles can exceed one meter within a few years. Rapid early growth reduces vulnerability to predators such as birds and larger reptiles. However, growth rates are highly sensitive to food availability and water quality. Polluted or overfished rivers slow development dramatically. Head-start programs capitalize on this rapid growth phase by rearing juveniles in protected environments. Size becomes a shield against early mortality.

Accelerated growth is an evolutionary response to high juvenile mortality. The faster a hatchling reaches substantial size, the lower its predation risk. Yet this strategy depends entirely on abundant prey. When fish stocks decline, growth slows and vulnerability persists longer. The survival clock stretches dangerously.
This growth dynamic transforms food web stability into a life-or-death equation. Conservationists must ensure fish populations remain sufficient not only for adults but for rapidly developing juveniles. The difference between a one-meter juvenile and a half-meter one can determine survival. In a shrinking habitat, growth speed becomes a critical metric of ecosystem health.
