Estuarine Fishery Resources and Physical Estuarine Modifications: Some Suggestions for Impact Assessment

摘要

A review of economically important fishery resources which are estuarine dependent in some life history stage is given and the potential value of these resources is considered. Some physical changes and consequences of estuarine modifications are categorized. Major probable fisheries impacts are described with some indication of tolerance by various life history stages. Examples of analytical procedures designed to assess fisheries impacts of estuarine modification are presented and discussed. The advantages, disadvantages and limitations of certain procedures are pointed out. A field experiment to determine ecological effects of an estuarine modification is outlined.
