Twenty-five species of fish, shrimp and prawn from local markets in Bangladesh were analysed for concentrations of total Fe, haem Fe and non-haem Fe by ICP-MS. Total Fe and non-haem Fe concentrations were measured in nitric acid-digested samples and haem Fe was extracted using acidified 80% acetone for 60 min. Total Fe concentrations ranged from 0.55 to 14.43 mg/100 g FW, and haem Fe% ranged from 18 to 93% of total Fe.
There is growing appreciation of the role of aquaculture in diversifying livelihoods of the poor. However, prevailing cultural norms and values, and social relations often influence its development outcomes, which we explore in this study. Socio-cultural dynamics affect the capacity of resource-poor and marginalized groups for the adoption and retention of aquaculture technologies.
It is widely recognized that women are significant actors in crop-livestock, pastoralist and fish systems. However, too little is known about agricultural development projects which deliberately work towards gender equity in livestock and fish value chains.
