Not AvailableGodavari hilsa shad is a premium priced and highly sought after anadromous fish that annually migrates from Bay of Bengal to the River Godavari, Andhra Pradesh, India during post-monsoon for spawning. The protein content was slightly higher in marine hilsa (22.69 % ). Wide variation in fat content of hilsa was observed during its anadromous migration. The fat content in the marine hilsa was 12.4% which increased in brackishwater habitat to 17.3% and progressively decreased in river habitat (14.51 to 8.78 % ). Polyunsaturated fatty acid (PUFA) content showed an increasing trend with lowest in marine hilsa (11.41 % ) and highest in Godavari hilsa (26.87 % ). Tetradecanoic acid (myristic acid) (325.3 mg % ) was the most prominent SFA and octadec-9-enoicacid (oleic acid) (816.8 mg % ) was the dominant MUFA in Godavari hilsa. Docosa-4,7,10,13,16,19-hexaenoic acid (DHA)(245.8 mg % ) was the most significant PUFA followed by eicosa - 5,8,11,14,17 - pentaenoic acid (EPA) (45.4 mg % ) and octadeca - 9,12,15 - trienoic acid (alpha-linolenic Acid) (42.1 mg % ). The results of the study show that nutritional composition of Godavari hilsa changes during its migration and the hilsa from River Godavari appears to be better than the marine hilsa from Bay of Bengal.Not Availabl
