What are the major breeding grounds for many fishes?
Plants and rocks. Fishes usually give birth in the shallow waters.
Swamps are a major buffer between the saltwater oceans and the freshwaters of the inland areas; they help to keep the inland areas from flooding by absorbing rainwater and storm surge waters (such as those generated by hurricanes). Swamps are also the breeding grounds for many animals such as alligators, mosquitoes, many birds and small mammals. There are undiscovered species deep in some swamps that may have medicinal properties as well.
