Analogue gravity succeeded to simulate Hawking radiation and test it in laboratories. In this setting, the black hole is simulated by an area in a fluid, say water, where no sound wave can escape the event horizon and phonon oscillations are detected as Hawking radiation. This means that the analogue simulations can provide an alternative description, and consequently, a new insight to the high energy physics problems. Now it would be interesting to see what information loss means and how island prescription is interpreted in water experiment. In this paper we show that the analogue of information loss is the loss of momentum per unit mass of the fluid over the horizon and maintaining the momentum loss leads to the island prescription.
