What will happen to the fish if its excretory system is disrupted?

Fish are characterized by the presence of certain structural features of the body, which allow them to live and reproduce under the water column. The excretory system plays an important role in the above process. Thanks to the excretory system, the fish is able to get rid of the accumulation of fluid in the body (release of its excess). As a result of this fact, it can be stated with full confidence that if the functioning of the excretory system is disrupted, the fish will die due to the rupture of the body.
