3. Bay of Bengal
It is located between latitudes 5°N and 22°N and longitudes 80°E
and 100°E.
It is approximately 1,000 miles (1,600 km) wide, with an
average depth near 8,500 feet (2,600 meters). The maximum depth
is recorded at 15,400 feet (4,694 meters).
Bangladesh is situated at the head of the Bay of Bengal.
Fisheries production in the Bay of Bengal is six million tonnes
per year, more than seven percent of the world’s catch.
The Bay of Bengal is an area of high biodiversity, with a large
number of endangered and vulnerable species.

6. What is Fishing Ground
 Fishing ground refers an area in a body of water
where fishes congregate and fishing is usually good.
 Generally a fishing ground is divided into two ways
permanent fishing ground and temporary fishing
ground.

7. Fishing Ground of Bay of Bengal
A part of a body of water where the fishing is usually good.
Fishing ground is those area of a water body where fish
concentration remains always significant. Generally fishing
ground is divided into two ways- permanent fishing ground
and temporary fishing ground. Bay of Bengal has four

15. Exclusive Economic Zone
 Generally, a state's exclusive economic zone is an area beyond and
adjacent to the territorial sea, extending seaward to a distance of not
more than 200 nmi (370 km) out from its coastal baseline.
 The exception to this rule occurs when exclusive economic zones
would overlap; that is, state coastal baselines are less than 400 nmi
(740 km) apart.
 EEZ of Bangladesh spans 164,000 km2 and the shelf area covers
roughly 66,440 km2
