In order to meet increasing demand for seafood worldwide Recirculation Aquaculture Systems (RAS) are frequently used. These systems are susceptible to contamination by waste matter including faecal material in the water. It is imperative that this material is removed from the system. The maintenance of good water quality is a pre-requisite to the success of the operation. Negligence in this area will adversely affect animal growth rates and also the economic performance of the system.
Micro-screen drum filters are a popular solution for the removal of this material (Cripps, Simon J. and Bergheim, Asbjørn., 2000). These screens are nominally rated …

Effects Of Conditioner Steam, Extruder Water And Screw Speed On Physical Properties Of Ddgs-Based Extrudates In Twin-Screw Extrusion, Parisa Fallahi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Mehmet Tulbek
Effects Of Conditioner Steam, Extruder Water And Screw Speed On Physical Properties Of Ddgs-Based Extrudates In Twin-Screw Extrusion, Parisa Fallahi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Mehmet Tulbek
Kurt A. Rosentrater
A fractional factorial design with a replicated central composite point was used to investigate the effects of extrusion processing on physical properties of DDGS–based aquafeeds using a twin screw extruder. Extrusion cooking trials were performed using an ingredient blend for Nile tilapia, with 2 levels of screw speed (350 and 450 rpm), 2 levels of extruder water (0.236 and 0.302 kg/min) and 2 levels of conditioner steam (0.1 and 0.15 kg/min). The central point was 400 rpm screw speed, 0.271 kg/min extruder water, and 0.12 kg/min conditioner steam. Effects of these processing conditions on extrudate characteristics were extensively analyzed, and …

Kurt A. Rosentrater
A single-screw laboratory extruder was used to conduct an L 18 (2 2 X 3 6 ) Taguchi fractional factorial study of aquafeed processing. The ingredients were based on a formulation for nutritionally-balanced Nile tilapia diets containing distillers dried grains with solubles (DDGS) and soybean meal as the main protein sources, in addition to constant amounts of corn flour, whey, and fish meal. The effects of three levels of DDGS (20, 30 and 40%), soybean meal (30, 40 and 50%), ingredient moisture content (20, 30 and 40% db), screw speed (100, 150 and 200 rpm), barrel temperatures (80-100-100°C, 80-120-120°C and …

Natural Resource Management Faculty Publications
Increases in global aquaculture production, compounded with limited availabilities of fish meal for fish feed, has created the need for alternative protein sources. Twinscrew extrusion studies were performed to investigate the production of nutritionally balanced feeds for juvenile yellow perch (Perca flavescens). Five isocaloric (~3.06 kcal/g) ingredient blends, adjusted to a target protein content of 36.7% db, were formulated with 0%, 10%, 20%, 30%, and 40% distillers dried grains with solubles (DDGS) at an initial moisture content of 5–7%db, with appropriate amounts of fish meal, fish oil, whole wheat flour, corn gluten meal, and vitamin and mineral premixes. …

Effect Of Starch Sources And Protein Content On Extruded Aquaculture Feed Containing Ddgs, Sankaranandh Kannadhason, Kasiviswanathan Muthukumarappan, Kurt A. Rosentrater
Kurt A. Rosentrater
A 3 × 3 × 3 completely randomized design was used to investigate extrusion cooking behavior and product characteristics of distillers dried grains with solubles (DDGS), protein levels, and various starch sources in a laboratory scale single screw extruder. Cassava, corn, and potato starches with varying levels of DDGS (20%, 30%, and 40% wet basis (wb)) were extruded with three different proportions of protein levels (28%, 30%, and 32% wb). The extrusion cooking was performed at a constant feed moisture content of 20% wb, barrel temperature of 120 °C, and a preset screw speed of 130 rpm (13.6 rad/s). Extrudate …

Building Integrated Aquaculture, Erik A. Woodin
Building Integrated Aquaculture, Erik A. Woodin
Masters Theses 1911 - February 2014
Exploratory research into a fresh concept, building integrated aquaculture, has found new information on the topic. Motives indicating building integrated aquaculture is important for sustainable development were identified. A review of the literature found relatively little in the way of experiments, aquaculture operations, and case studies which documented or demonstrated a deep understanding of the interactions between building and aquaculture systems. A simple experiment was conducted observing thermal energy and moisture interactions in simulated aquaculture facilities, some with tank covers and insulation. Two different retrofit programs were developed in a case study of building integrated aquaculture for an existing structure …
Building A Sustainable Seafood System For Maine, Robin Alden
Building A Sustainable Seafood System For Maine, Robin Alden
Maine Policy Review
In this article, Robin Alden notes that Maine could have one of the premier marine food systems in the world. However, that means adequate stewardship of the Gulf of Maine ecosystem and diversifying the fishing industry beyond lobster by creating innovative public policy and a food system that supports community fishing.
