Questions 1. Is there a correlation between juvenile fish community structure and
intertidal habitats? |
Background • The intertidal zone, the area of shore between high and low tides, is used as a temporary habitat for many species of juvenile fish. • Growth rates vary as a function of habitat; therefore, selection of habitats that maximize growth is a crucial factor in survival for fishes. • Determining which intertidal habitats are most important to local species will aid in conservation. |
