Topic: "Environmentally Responsible and Sustainable Seafood Production in the United States: Cost and Energy Analysis" 

Presenter: David E. Brune 
Professor of Bioprocess and Bioenergy Engineering 
University of Missouri 

Since 2010 the author has installed, operated, and demonstrated two 100 m2 marine shrimp production prototypes at the University of Missouris Bradford Research and Extension Center. Culture trials conducted during the summers of 2012 and 2013 demonstrated zero-discharge production of pacific white shrimp at carrying capacities exceeding 25,000 kg/ha, integrated with harvesting and processing of microbial biomass production yielding co-production of animal feeds and bioenergy. These systems have been designed and operated as 100% self-contained units, with no discharge of water or wastes to the environment. Energy balances and enterprise budgets were prepared comparing the energy and cost footprint of marine shrimp production under both plastic-covered high-tunnels, as well as, contained within insulated metal buildings. Furthermore, shrimp system productivity and costs were compared in systems using algal based water quality control, as opposed to bacterial culture for water quality control. 

An overview of systems design and operation, as well as, capital investment required, projected cash-flow and potential profit will be presented. Net production cost of shrimp is predicted to range from $4.10 - $6.65/lb, comparing favorably with imported shrimp production costs of $2.02- $4.83/lb grown using current unsustainable Asian pond culture technology. Net shrimp energy production requirement is predicted to range from 3.8-7.7 kw-hr/lb comparing favorably with Asian pond energy requirements of 4.8-5.9 kw-hr/lb and much lower than the 24 to 35 kw-hr/lb for pork and beef production. Total system capital investment ranges from $630K/acre to $1.600K/acre, potentially generating $250K-$1,000K/acre-yr in gross revenue. The bacterial water quality control option is projected to provide highest income at highest input level and with greatest risk. The 100% algal option would yield least risk at lowest level of input per unit of capital investment however, system performance is more dependent on facility location and climate, insuring maximum algal productivity. 

David Brune received his B.S. and M.S. in Agricultural Engineering and PhD in Sanitary Engineering from the University of Missouri-Columbia. He has served on the faculty at the University of California-Davis, Penn State University, Clemson University and most recently, at the University of Missouri. His R&D activities at Clemson University in South Carolina led to the patented, Partitioned Aquaculture System and Controlled Eutrophication Process. Versions of these fish production systems are being installed by farmers across the southern U.S. Currently, at the University of Missouri, he leads a research and extension effort targeting development and deployment of zero-discharge, integrated aquaculture systems supporting environmental friendly co-production of seafood and bioenergy 

Coffee and cookies will be served.
