Figure 1

Area maps of six main fatty acids and total fatty acid content. (A) All gonad samples are ordered by total fatty acid content. (B) All muscle samples are ordered by total fatty acid content

Figure 2

Redundancy analysis (RDA) graph of gonad and muscle samples. (A) Gonad samples from the Chinese mitten crab reared using two different types of feed are clustered in two different regions and showed significant separation (p < 0.05). (B) Muscle samples from the Chinese mitten crab reared using two different types of feed also are clustered in two different regions and showed significant separation (p < 0.05)

Figure 3

Comparison of average fatty acid content in samples from crabs receiving different types of feed. (A) Comparison of levels of different fatty acids in gonad samples from different feed groups. (B) Comparison of levels of various fatty acids from muscle samples from different feed groups

Figure 4

Fatty acid composition in formulated feed and frozen trash fish

Figure 5

Correlations between fatty acids in feed and fatty acids in samples. (A) Analysis of correlation between levels of fatty acids in samples and their levels in feed by using levels of fatty acids in feed (y-axis coordinates) and their corresponding levels in crab gonad samples (x-axis coordinates). (B) Analysis of correlation between levels of fatty acids in samples and their levels in feed by using levels of fatty acids in feed (y-axis coordinates) and their levels in crab muscle samples (x-axis coordinates)

Figure 6

Nutritional value of fatty acids. (A) Comparison of SFA, MUFA, PUFA, and trans-fatty acid levels between gonad and muscle samples from two different feed groups and common food products. (B) Comparison of total fatty acid content between gonad and muscle samples from crabs receiving two different types of feed and different fish products. (C) Comparison of total ω-3PUFA and ω-6PUFA content between gonad and muscle samples from crabs receiving two different types of feed and different fish products. (D) Comparison of DHA+EPA content between gonad and muscle samples from crabs receiving two different types of feed and different fish products. Data on other fish products come from Zhang et al. (2014).
