Ecophysiology of Marine Bivalves : Physiological Rate Processes in Dynamic Environments

Creator:: Gray, Matthew W.
Abstract:: Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally,...

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...

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...

Utilization of dietary protein by the mussel, Mytilus edulis trossulus (Linnaeus 1758)

Creator:: Kreeger, Daniel A.
Abstract:: Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...

Enrichment of Live Prey with Microparticles for the Enhanced Delivery of Water-soluble Nutrients to Marine Fish Larvae

Creator:: Hawkyard, Donald Matthew
Abstract:: In the wild, marine fish larvae feed on copepods and other planktonic organisms. Copepods are often considered the "gold standard" for meeting the nutritional needs of cultured marine fish larvae; however, in captivity, marine fish larvae are generally fed cultured live prey, i.e. rotifers (Brachionus plicatilis) and/or Artemia sp., until...

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...

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...

Development of microparticulate feeds and methods to improve acceptability of artificial diets by blue spotted goby larvae (Asterropteryx semipunctata)

Creator:: Clack, Brendan W.
Abstract:: An acceptable microparticulate diet for marine fish larvae may be defined as an artificial diet that contains, retains, and delivers the required nutrients to support survival and growth. Factors affecting ingestion rate of prey items by fish larvae include environmental factors such as light intensity, prey/background contrast, possible chemical cues,...
