5.3.8 Crab
Crab extraction is a relatively more prospective from economic point of view. It is almost an
annual activity. An average crab collector earns annual income in the range of Tk 86,334 (much
higher compared to products such as golpata or fish), almost progressively followed by
Majhis/Farias (Tk 158,582), Choto Mahajans (Tk 231,264), Boro Mahajans (Tk 487,307),
Aratdars (813,512) and wholesalers (Tk 632,490) (Table 5.28). Like in most other products,
Aratdars in this value chain earn the highest amount of income. The degree of inequality appears
to be high in that the average annual income earned by the collectors, for example, estimates as
more than 9 times as less as earned by an Aratdar.
In terms of total income aggregated for all actors, only 3.6 percent is due to collectors, followed
by Majhis/Farias (6.6%), Choto Mahajans (9.6%), Boro Mahajans (20.2%), Aratdars (33.8%),
and wholesaler (26.3%).
In terms of distribution by deciles, the income distribution appears to be much skewed (Table
5.29). Considering two deciles, Decile 1 for the bottom-ranking actors and Decile 10 for the top-
