This project has demonstrated that juvenile Greenshell mussels can uptake dissolved glucose and use this source carbohydrates to fuel growth and improve their nutritional composition when used as a supplementary feed with live microalgae.

• Probiotics applied at appropriate concentration on feed or in the water column strains can significantly increase survival rates in marine shrimp when exposed to EMS/AHPNS strain of Vibrio parahaemolyticus.
• Probiotic prophylaxis was reliant upon concentration, regardless of the route of application on the feed or in the water column.
• Methods presented in this study can serve as a model for other researchers and producers to evaluate probiotics, prebiotics, or other materials for EMS/AHPNS disease protection.

The aim of this study was to investigate the effects of TBT, TPT and SnCl2 on the embryonic development of zebrafish. In this study, zebrafish embryos were used to observe the acute toxicity of TBT, TPT and SnCl2. Fish embryo toxicity analysis was performed for different TBT, TPT and SnCl2 concentrations (20, 15, 10, 5, 1 ng/L).

The objective of this study was to develop a conceptual model that may identify stocking locations that can help improve survival of stocked Walleye and White Bass. Final stocking maps identified the best 12.8 and 13.9% of the predicted area of Lake McConaughy for stocking Walleye and White Bass, respectively. The maps for both species were interestingly similar. These results are likely due to the similarities in predators consuming the stocked products and the zooplankton consumed by fingerlings of both species.
