Sada (large) Fish
The degree of inequality in the value chain appears to be quite high in that the average annual
income earned by the collectors, for example, estimates as more than 10 times as less as earned
by an Aratdar. In terms of deciles distribution of income, top 10 percent of the actors earn as
high as 19 times as much income as the bottom 10 percent (i.e., 1:19) (See Figures 5.61 and 5.62.
Gini coefficient for Sada (large) fish estimates as 0.44, which is a bit lower compared to most
other SRF products.

Hilsha
The average annual income earned by the collectors, for example, estimates as nearly 8 times as
less as earned by a Boro Mahajan. Considering two deciles, the top 10 percent of the actors earn
as high as 42 times as much income as the bottom 10 percent (i.e.,1:43). Gini coefficient for
hilsha fish estimates as 0.48, which is a bit lower compared to gura and sada fish.
