Book Description
Gray snappers were collected from four different habitats and examined for trematodes. The incidence of each trematode was calculated for each habitat during each season. Intermediate hosts of the trematodes were also collected. It was found that the habitat in which gray snappers reside is more important than their size, sex, or the season of the year in determining the nature of their trematode populations. This may be the result of the intermediate host distribution being regulated by the habitat. Seasonal changes in trematode populations result from fish movements, such as spawning migrations or movements in response to cold water. The differences between the trematode populations of large and small snappers probably are a function of their residing in different habitats and eating different organisms. The sex of gray snappers has no discernable [i.e. discernible] effect on their trematode populations. Metadena obscura sp. n. (Cryptogonimidae) was found in the pyloric caeca and intestine of Lutjanus griseus (Linnaeus). Nine species of trematodes were found in the intestine and pyloric caeca of Lutjanus griseus near Lower Matecumbe Key: Metadena globosa, M. adglobosa, M. obscura, Paracryptogonimus neoamericanus, Hamacreadium mutabile, H. gulella, Helicometrina nimia, Helicometra execta, and Stephanostomum casum.

Book Description
Chemistry, Biology, and the Estuarine System is the first volume of a series launched by Estuarine Research Foundation to present information and concepts regarding the estuaries in the world. The contents of this volume are papers presented in a conference held in South Carolina in October 1973. The book is divided into three major subject areas, namely, Chemistry, Biology, and Estuarine System. The first part focuses on the cycling of elements and estuaries. The second part deals with the dynamics of the food webs in various estuaries. The last section discusses the estuarine system, specifically estuarine modeling. In this part, several estuarine models in different locations are explored. Model analysis as well as utility of systems models is covered in this section. This volume serves as a valuable source of information to interested parties in the field of ecology, biology, chemistry, environmental science, etc.
