Evaluation of spray-dried microalgae in diets for juvenile Manila clam Tapes philippinarum

Creator:: Önal, Ebru
Abstract:: Effects of spray-dried algae, Schizochytrium sp. and Haematococcus pluvialis, on growth and survival of Manila clam, Tapes philippinarum, spat were determined. Results of the present study showed that these two different spray-dried diets supported clam growth when added as supplements to rations of a mixed diet of the live algae...

Enhanced production of Pacific dulse (Palmaria mollis) for co-culture with abalone in a land-based system

Creator:: Demetropoulos, Carl Lee
Abstract:: Palmaria mollis (Pacific dulse) is increasingly being used in land-based marine aquaculture. This work elucidates nutrient, inorganic carbon, light, salinity, and temperature requirements of P. mollis as food for abalone species. Nutrient additions every 5 to 7 days resulted in no significant difference in P. mollis growth compared with daily...

Development of artificial diets for delivery of water-soluble nutrients to altricial fish larvae

Creator:: Onal, Umur
Abstract:: In the present study, the potential of low-melting point lipids, namely methyl palmitate (MP) and menhaden stearine (MS), were studied for delivery of water-soluble materials to fish larvae. Addition of the solid emulsifier, sorbitan monopalmitate (SMP) resulted in higher RE compared to the liquid emulsifier sorbitan sesquioleate (SSO). Additions of...

Improving Pacific oyster (Crassostrea gigas) production through selective breeding

Creator:: Evans, Sanford, 1968-
Abstract:: Shellfish growers have expressed interest in developing high-yielding oyster strains through selective breeding. This dissertation has three objectives to help determine the effects of genetic and environmental variation on production traits (body weight, survival, and yield) of Pacific oysters grown in the Pacific Northwest. Objective 1: Determine if relative family...

Integrating fleets, markets and ocean dynamics : a bioeconomic analysis of the Oregon ocean shrimp fishery

Creator:: Gallagher, Charmaine Marie
Abstract:: Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...

Is the laboratory growth of Pacific oyster spat, Crassostrea gigas, exposed to varying salinities, predictive of their growth in the estuary?

Creator:: Brooks, Christopher
Abstract:: Results of this study suggest that laboratory growth of full-sib families of five month old Pacific oyster spat can be predictive of growth to market size at different grow-out sites. Seven to ten millimeter spat were selected from each of fifteen full-sib families and commercially available polyploids. Each family was...

Microencapsulation of water-soluble substances for delivery to marine bivalves

Creator:: Buchal, Michael A.
Abstract:: A new method for encapsulating low-molecular weight, water-soluble substances in lipid-walled microcapsules (LWMs) for delivery to marine bivalves was developed, characterized, and tested. LWMs produced by a spray technique (spray microcapsules, SMs) were demonstrated to encapsulate both aqueous (polymeric dye or oxytetracycline hydrochloride) and particulate (riboflavin) core materials within a...

Growth and survival of zebrafish, Brachydanio rerio, larvae fed on two types of microparticulate diets

Creator:: Onal, Umur
Abstract:: Effects of diet and container type on growth and survival of altricial zebrafish, Brachydanio rerio, larvae were determined. Microfeast® L- 10 (MF) supported growth and survival of zebrafish larvae during the first 10-12 days. Best results were obtained with larvae fed on a combination of MF and Artemia nauplii in...

The use of wax spray beads (WSB) for iodine enrichment of Artemia sp. for use as a live food for zebrafish (Danio rerio) larvae

Creator:: Hawkyard, Donald Matthew
Abstract:: Dietary iodine may play an important role in the nutritional health of freshwater fish larvae. Artemia, commonly used for the culture of larval zebrafish (Danio rerio), contain low concentrations of iodine when compared with wild zooplankton. Water-soluble micronutrients, such as iodine, are difficult to deliver to Artemia due to rapid...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...
