Abstract

Size measurements of fish and crustacean species play a critical role in fishery stock assessments, fishing gear size selectivity studies, and monitoring compliance with fisheries management regulations. One such example is from shrimp fisheries where samples of trawl-caught shrimps are frequently collected and size measured. However, the manual measurement of hundreds of small shrimps per sample is time-consuming and exhausting. Therefore, this study evaluates whether an automatic measuring procedure using off-the-shelf camera technology and a general-purpose artificial intelligence algorithm can replace manual measurements of deep-water shrimp (Pandalus borealis). Despite some deviations between manual and automatic measurements for individual shrimps, the automatic method proved sufficiently accurate for stock, gear selectivity and compliance assessment. Furthermore, this study demonstrated how a use-case driven approach can be applied when evaluating whether a new measuring technology can replace an existing.

在评估捕虾渔业时，自动测量能否取代人工？

鱼类和甲壳类物种的尺寸测量在渔业资源评估、渔具尺寸选择性研究和监测渔业管理法规遵守情况方面发挥着至关重要的作用。其中一个例子是捕虾业，经常收集拖网捕获的小虾样本并进行尺寸测量。然而，人工测量每个样本中的数百只小虾既费时又费力。因此，本研究评估了使用现成相机技术和通用人工智能算法的自动测量程序能否取代人工测量深水对虾（Pandalus borealis）。尽管人工测量和自动测量对虾个体存在一些偏差，但自动测量方法被证明对种群、渔具选择性和合规性评估足够准确。此外，这项研究还展示了在评估一项新的测量技术是否能取代现有技术时，如何采用用例驱动法。
