aquaculture principles in the first session of the conference in addition to a technical discussion on thick-film biofiltration methods during a session focusing on technologies of intensive aquaculture operations. Raul Piedrahita, another CRSP researcher from the University of California, Davis, also participated in this session, delivering a presentation entitled “Solids removal in intensive aquaculture systems.”

There was also a session devoted entirely to pond dynamics, which included additional presentations

Several current and former PD/A CRSP researchers participated recently in the Western Regional Aquaculture Expo 2000, an event sponsored by the California Aquaculture Association. CRSP researcher Claude Boyd was the keynote speaker at the conference held in Desert Hot Springs, California, February 27–March 1.
by Boyd and a presentation by former CRSP researcher Chris Knud-Hansen. Boyd began the session with an overview of the PD/A CRSP, describing current research priorities and goals. He also gave an overview of his own pond soil research, describing the interaction of sediments and water in pond aquaculture systems. Chris Knud-Hansen delivered a talk entitled “An ecological approach to optimize pond fertilization,” in which
Boyd’s keynote address focused on the environmental effects of aquaculture and the need for aquaculture producers in the United States to adapt to increasing government scrutiny and changing public perceptions of the aquaculture industry. Additional conference topics ranged from aquaculture basics such as site selection and disease prevention to the marketing and transportation of aquaculture products.
