Fish in urban environments

In the urban environment the impact of human activity often results in the construction of tidal barriers to estuarine fish passage and/or highly modified fish habitats. The modified, shallow estuarine habitat of the urban Rockdale wetland corridor, Botany Bay, is used by estuarine fish and its functional equivalency compared with similar non urban habitats is demonstrated. The argument is presented that estuarine fish are part of the urban wildlife fauna and they should be included in education and advisory programs developed and coordinated by various groups to protect, enhance and maintain wildlife populations in the urban environment.
