A Study Of Nutritional Requirements Of The Larvae Of The American Oyster (Crassostrea Virginica), Fu-Lin E. Chu Jan 1982

A Study Of Nutritional Requirements Of The Larvae Of The American Oyster (Crassostrea Virginica), Fu-Lin E. Chu

Dissertations, Theses, and Masters Projects

The purpose of this study is to obtain information for the formulation of artificial diets for larvae of the American oyster (Crassostrea virginica) and to test procedures related to presenting these diets to the oyster larvae. In order to determine the nutrient components usually provided in larval diets, biochemical analyses of lipids and fatty acids, proteins and amino acids and polysaccharide carbohydrates were performed on five algae species used as a food source for oyster larvae. These algae are Chlorella sp., Pyramimonas virginica, Pseudoisochrysis paradoxa, Pavlova (Monochrysis) lutheri and Isochrysis galbana. The biochemical analyses indicate that the nutritional value of …

Influence Of Temperature On The Immune Response Of Juvenile Summer Flounder, Paralichthys Dentatus, And Its Role In The Elimination Of Trypanoplasma Bullocki Infections, Joseph P. Sypek Jan 1982

Influence Of Temperature On The Immune Response Of Juvenile Summer Flounder, Paralichthys Dentatus, And Its Role In The Elimination Of Trypanoplasma Bullocki Infections, Joseph P. Sypek

Dissertations, Theses, and Masters Projects

Two groups of juvenile summer flounder maintained at 5�C were experimentally infected with the hemoflagellate Trypanoplasma bullocki. Another group maintained at 5�C was not infected. The water temperature of one infected group was raised stepwise to 12�C, 18�C, and 24�C for 2 to 3 weeks at each level. The other infected group was maintained at 5�C for 12 weeks, the duration of the experiment. In addition, juvenile flounder were collected over a temperature range of 6�C to 22�C from February to June, 1982 to monitor natural infections. Live T. bullocki were incubated in plasma from fish at each temperature to …
