Mortality
due to human activities
The
North Atlantic right whale, Eubalaena
glacialis
had been hunted intensively by human for commercial purposes.
The
North
Atlantic right whales
have been hunted down for long time period, around 40 years or from
1890 to 1930. Hunting for their:
-
meat
-
oil
-
baleen
Whaling
license is terminated since 1930, and even USA government prohibits
individuals or institution or human vessels to approach North
Atlantic right whale within 457 m or 1500 ft distance.
However,
whale population is not recovered as normal as before 1890. Eubalaena
glacialis is about 411
only in current estimation.
Surprisingly,
mature female is predicted 90 to 100 only. No breeding was detected
for last year, 2018.

Low
breeding rate combined with mortality due to human activities such as
ship strikes and entanglement, lead whales to nearly in extinction
phase.
The
North Atlantic right whale is considered as most endangered species
compared to other whales.
Luckily,
scientists have been detected totally 7 whale’s babies this year
(2019), included 3 in recent weeks.
The
mature whales come to breeding ground in coast off Georgia and
Florida during winter season. Temperature is quite higher in southern
part compared to northern part of America.
In
spring and summer, whales and their calves goes back to their feeding
ground in New England, Northern America, includes Canada.
Unfortunately,
it is predicted that the
North Atlantic right whales would extinct by next 20 years if these
things continue to
happen:
-
High
mortality
of whales due to human activities.
-
Lower
breeding rate
Human
activities included, but not limited to:
-
entanglement
of fishing gear
-
ship strikes
-
vessel noises
Have
You an idea to
prevent the
North Atlantic Right Whale from extinction?
