INTEGRATED PROTECTED AREA CO-MANAGEMENT (IPAC) - BIDS

Shrimp Large (galda and bagda)
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 5 to 7 times as less as
earned by an Aratdar.
Shrimp Small (galda and bagda)
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 7 to 8 times as less as
earned by a Boro Mahajan for galda and bagda shrimp respectively.
Shrimp Fry (galda and bagda)
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 9 times and 2.5 times as
less as earned by an Aratdar for galda and bagda respectively. Gini coefficient for shrimp fry
estimates as 0.44, which is a bit lower compared to those of most other SRF products.

Crab
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 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 topranking
actors, it can be seen that the top 10 percent of the actors earn as high as 35 times as
much income as the bottom Decile 1 (i.e., 1 : 35). Gini coefficient for crab estimates as high as
0.52.
