We study the entanglement entropy of a subsystem in contact with symmetricalbath where the complete system lives on the boundary of AdS3 spacetime. Thesystem-A is taken to be in the middle of the bath system-B and the full systemis taken to be some fixed localized region of the boundary 2-dimensional CFT.We generally assume that the d.o.f.s in the total system remain fixed when wevary the size of the bath which is to be guided by the conservation laws. It isfound that the island and the subleading (icebergs) contributions areinseparable, and in totality they contribute nothing to the Page-curve of theradiation. As such they contribute only to the unphysical branch of theentropy. The entropy formula of the radiation may simply be written as minimumof {S[A],S[B]} including for the black holes.

Islands and Icebergs contribute nothing to the Page curve (System with a symmetrical bath)
