Abstract
ObjectiveAs a type of automatic feeder, demand feeders reduce labor costs and can improve fish‐rearing efficiencies. However, mounting demand feeders can be problematic because of the variety of nonstandardized fish‐rearing units. This article describes an innovative, simple, sturdy, and durable demand feeder mount for rectangular, concrete raceways.MethodsThe feeder mount was made from aluminum and sits flat on a raceway wall or walkway. A horizontal base plate, secured to the wall by vertical plates, holds a vertical riser of aluminum tubing. Attached to this tubing is a rod that secures the demand feeder.ResultThis feeder mount design has proven durable over several years of actual use. Over this time, it has needed no maintenance other than occasional cleaning with water to remove spilled fish food. The feeder can be easily and quickly removed from the mount by simply pulling a pin and sliding the feeder off of the tubing. The mount is constructed to dramatically reduce tripping hazards and occupational safety and health risks.ConclusionThis simple, inexpensive (~US$50 to construct), and no‐maintenance mount is a viable solution to the typically difficult problem of mounting demand feeders to concrete raceways used for trout production.
期刊介绍:
The North American Journal of Aquaculture publishes papers on new research and practical experience in all areas of intensive and extensive fish culture. Topics include broodstock selection and spawning, nutrition and feeding, health and water quality, facilities and production technology, and the management of ponds, pens, and raceways.
The journal will consider papers dealing with ways to improve the husbandry of any aquatic species—marine or freshwater, vertebrate or invertebrate—raised for commercial, scientific, recreational, enhancement, or restoration purposes that may be of interest to practitioners in North America. Its scope includes both basic and applied science, but applied scientific endeavors—including practical experiences, descriptive studies, and other nontraditional, but pertinent works—are emphasized.
