Solution
You are connecting two different concepts.
1. Both fishes and ship have the same shape : This means that both of them have a streamlined shape so that they move in water with minimum resistance. This has nothing to do with float or sink, this relates to the viscous drag force
(in simple words-liquid friction)
2. Ship floats in water : Archemedes' principle. The weight of the water displaced by the ship is equal to the weight of the ship, which causes the ship to float in water.
