摘要

體色是水生動物品質及價格的重要評比項目。依使用者特定的需求，像是實用性、應用性、準確度、資源可用度等，數種方法被用來評估這些動物的皮膚與肉的呈色。衡量水生動物呈色的方法依樣本被量取的化學成分或物理顏色而分為化學及物理方法。這些方法以下面評比項目：方法的描述、樣本狀況、儀器、耗時與成本、以及表現而進行描述與比較。化學方法是目前普遍使用來分析水生動物的呈色效應，然而若能與物理方法結合，則能獲得色素濃度與顏色間的相關性。數位影像攫取及處理方法的新的應用可以分析水生動物在不同發展期其色素細胞的形態及色素特性，使得這領域將來的研究打開了新的機會。

Body color is an important criterion of quality and price of aquatic animals. Several methods have been used to assess the pigmentation in the skin and flesh of these animals, depending on users' specific requirements such as practicality, applicability, accuracy, resource availability, etc. The methods for measuring pigmentation in aquatic animals can be grouped into chemical and physical ones, based on whether the chemical components or the physical color of the sample is measured. The methods were described and compared by the following criteria: method description, sample condition, instrumentation, time and costs and performance. The chemical methods are common methods used nowadays to analyze the pigmentation effect in aquatic animals, nevertheless, by combining the use of chemical and physical methods, correlation of pigment concentration and color can be achieved. A new application of digital image acquisition and processing allows the analysis of morphological and chromatic characteristics in chromatophores in aquatic animals at different developmental stages, opening new opportunities for further research in this field.
