One of the critical challenges that the global salmon farming industry will confront when upscaling production is accurate biomass control. Commercial salmon farming requires a significant level of certainty regarding fish count, average weight measurement, live weight distribution, and other production indicators. A reliable control system for assessing the biomass of farmed Atlantic salmon is essential for sustainable and cost-effective precision aquaculture. A study was done in four production sea-cages in a Chilean Atlantic salmon marine grow-out farm to estimate the average weight and frequency distribution utilizing the Vaki Biomassdaily® diode frames as an alternate technology to manual weight measurement. From post-smolt reception to fish harvest, diode frames were put in each sea-cage in a secure position for 15 months. There were no significant changes in length or average weight between manual sampling and frame estimate. The mean degree of accuracy for the average weight estimation was 98.83 % for the frames utilized in the four sea cages. The diode frames also achieved a high degree of precision in predicting the frequency distribution of fish. There were no statistically significant variations between the distribution variances of the diode frame measurements and the distribution variances of the fish received at the fish processing facility (FPF). The maximum difference between the average weight calculated by the frames and the average weight of the fish received in the processing facility was 2.4 %, with 99.66 % being the highest accuracy with only 19 g of difference. We determined that diode frames might replace manual weight assessments with greater reliability for growth monitoring and production management. To assure the optimal performance of the diode frames in terms of accuracy and precision for future commercial-scale validations in the salmon farming business, the development of a standard best practice manual is necessary.

在扩大生产规模时，全球鲑鱼养殖业将面临的关键挑战之一是准确的生物量控制。商业鲑鱼养殖需要在鱼类数量、平均重量测量、活体重量分布和其他生产指标方面具有高度的确定性。用于评估养殖大西洋鲑鱼生物量的可靠控制系统对于可持续且具有成本效益的精准水产养殖至关重要。在智利大西洋鲑鱼海水养殖场的四个生产海笼中进行了一项研究，以利用 Vaki Biomassdaily® 二极管框架作为手动重量测量的替代技术来估计平均重量和频率分布。从幼鱼后接收到鱼类收获，二极管框架被放置在每个海笼中的安全位置 15 个月。人工抽样和框架估计之间的长度或平均重量没有显着变化。对于四个海网箱中使用的框架，平均重量估计的平均准确度为 98.83%。二极管框架在预测鱼的频率分布方面也达到了高精度。二极管框架测量的分布方差与鱼类加工设施 (FPF) 接收的鱼的分布方差之间没有统计学上的显着差异。由框架计算出的平均重量与加工设施中收到的鱼的平均重量之间的最大差异为 2.4%，其中 99.66% 是最高的准确度，只有 19 克的差异。我们确定二极管框架可能会以更高的可靠性取代手动重量评估，以进行生长监测和生产管理。为了确保二极管框架在未来鲑鱼养殖业务的商业规模验证的准确性和精度方面的最佳性能，有必要制定标准的最佳实践手册。
