Quantitative genetics of chum salmon, Oncorhynchus keta (Walbaum)

Creator:: Smoker, William Williams
Abstract:: Chum salmon from different stocks were bred together in two experiments. Three stocks contributed gametes to one experiment, two stocks to another. Sibling groups of eggs, alevins, and fry were maintained in a common environment. Variability of development rates, rearing performance, susceptibility to disease, and behavioral traits was partitioned into...

Evaluation of combining ability in mosquitofish

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...

Nile tilapia (Oreochromis niloticus) production in tropical microcosms fertilized with rabbit excreta

Creator:: Franco, Luis
Abstract:: This investigation explored the use of microcosms as a tool for studying the dynamics of tropical aquaculture ponds. The potential use of rabbit excreta as a pond fertilizer in integrated farming systems was also investigated. Twelve insulated fiber glass tanks were utilized as microcosms to simulate earthen ponds. Seven hand-sexed...

A mendelian study of Crassostrea gigas

Creator:: Smoker, Janet Van Dusen
Abstract:: The genotype frequencies of one-year-old oyster spat (Crassostrea gigas) from parents of known genotype, are compared to the frequencies expected with Mendelian inheritance. The genotypes are characterized at three enzyme loci, Aspartate amino-transferase (AAT), Phosphohexose isomerase (PHI) and Leucine aminopeptidase (LAP), and a general protein locus. In this study expression...

Classification and management of earthen aquaculture ponds, with emphasis on the role of the soil

Creator:: Bowman, James R.
Abstract:: Soil, water, and climatic classification systems are reviewed as background for the construction of a classification system for earthen aquaculture ponds. The physical and chemical properties of important soil types are also reviewed because of the critical role that the soil plays in earthen pond systems. A pond classification system...

Total and available nutrients in manures for pond aquaculture

Creator:: Nath, Shree S.
Abstract:: The total amount of nitrogen and phosphorus in animal manures, and the proportion of this amount that becomes available as dissolved inorganic nitrogen and phosphorus within a month after manures are added to water were examined in the context of fertilization guidelines for pond aquaculture. A literature study was conducted...

Development of a decision support system for pond aquaculture

Creator:: Nath, Shree S.
Abstract:: Decision support systems (DSS) have been used to a very limited extent in pond aquaculture. This study documents the development of a DSS (POND) which allows representation of an entire pond aquaculture facility, and provides analysis capabilities in the form of simulation models and an economics package. Simulation tools in...
