摘要: Go lden shiners Notemigonus crysoleucas are typically graded in concrete vats having a rectangular cross section. Aluminum frames fitted with panels of uniformly spaced, vertical rods (bar graders) used to separate golden similar weight and length fro m mixed -size aggregation. Investigation revealed that no quantitative method for estimat ing bar grader effectiveness existed, so Microsoft © Exce l application was developed. The shiner assessment model presents product quality information g raded crysoleucas. Quality assurance data includes an estimate the number fish per kilogram (kg), kg 1,000 fish, grading effectiveness. Standard calculations give benchmark criteria shiners, whereas relative provides general indicator health, means feed regimen. This serves as tool researchers, management producers, source important informat ion purchasers.
