Recognising the importance of fish in the Bangladeshi diet, the objective of the present study was to screen commonly consumed fish species for vitamin A content to evaluate the potential of fish as a vitamin A source in food-based strategies to combat vitamin A deficiency. Samples of 26 commonly consumed fish species and one crustacean were collected in Kishoreganj and Mymensingh, Bangladesh. To obtain edible parts, the fish were cleaned by Bangladeshi women according to traditional practices. Distribution of vitamin A in parts of the fish and the effect of the cleaning practices on the vitamin A content in edible parts were assessed. The content of vitamin A compounds was analysed by high-performance liquid chromatography. The vitamin A content in small fish ranged from 2680 retinol equivalents (RE) /100 g raw edible parts in mola (Amblypharyngodon mola) to 20 RE/100 g raw edible parts in chata (Colisa lalia; an alternative scientific name is Colisa lalius). The vitamin A content in cultured species, silver carp (Hypophthalmichthys molitrix), rui (Labeo rohita), mrigal (Cirrhinus mrigala) and tilapia (Oreochromis niloticus) was low, <30 RE/100 g raw edible parts. In mola, 90% of the vitamin A was found in the eyes and viscera. The vitamin A content in the screened fish species was highly variable, by more than a factor of 100. The existence of commonly consumed fish in Bangladesh belonging to the categories of very high and high vitamin A content offers a great unexploited potential for foodbased strategies to improve the vitamin A intake by promoting the production and consumption of these species.
