Evaluation Of Growth, Production And Cold Tolerance Of Four Varieties Of Tilapia, Patricio Enrique Paz Jan 2004

Evaluation Of Growth, Production And Cold Tolerance Of Four Varieties Of Tilapia, Patricio Enrique Paz

LSU Master's Theses

As global tilapia production grows, it is important to characterize varieties available for production and generate data on environmental tolerances. This study generated data on tolerances, adaptabilities and production characteristics of four tilapia varieties. Goals of this study were to: (1) compare growth of four tilapia varieties in two types of recirculating systems, (2) evaluate juvenile growth of seven tilapia varieties in fresh and brackishwater mesocosms, and (3) estimate cold tolerance of juveniles of four tilapia varieties in fresh and brackishwater. Nile tilapia (Oreochromis niloticus), blue tilapia (Oreochromis aureus), Mississippi commercial strain tilapia (MCS), and Florida red tilapia (FRT) were …


Dry Matter Accumulation By The Start Of Seed Filling As A Criterion For Yield Optimization In Soybean, Harikrishna Modali Jan 2004

Dry Matter Accumulation By The Start Of Seed Filling As A Criterion For Yield Optimization In Soybean, Harikrishna Modali

LSU Doctoral Dissertations

Identification of criteria for predicting soybean [Glycine max (L.) Merril] yield would provide farmers with useful management tools. Such criteria not only help in predicting the yield potential but also aid the farmer in determination of environmental factors limiting crop yield. Since a certain total dry matter (TDM) level is expected to optimize yield and R5 marks the end of the period for vegetative TDM accumulation, TDM(R5) is a good putative criterion for optimal yield. Determination of yield components important in yield formation helps to substantiate TDM(R5) as a criterion for optimum yield, since they are formed during discrete periods …


Growth, Lori Penn Jan 2004

Growth, Lori Penn

LSU Master's Theses

Every living being encounters growth. As humans, our experiences help to shape our mental and emotional development. Each of these experiences provides an opportunity for growth. In my work, apes, monkeys, and lemurs serve as visual metaphors for human growth. The body of work that I created for my thesis project reflects different emotions and experiences that facilitate growth and maturity.
