Killer Whales Endangered
Killer Whale Conservation
The Killer Whale has declined in overall
numbers due to the environment and human actions. Right now
they aren’t considered to be an endangered species, but that
doesn’t mean effective conservation efforts aren’t necessary.
This is especially true in certain habitat locations where the
numbers are decreasing very rapidly. Research has shown some
Killer Whales are threatened by the loss of their natural
habitat as well as a reduction in food supply in some
areas.
These animals consume tons of food daily, and that is a
concern. In many areas they are consuming the same fish that
fishermen want to make a living from. As the amount of food is
reduced they may have to move further to find more of it. This
is where they end up injured or killed due to fishing nets or
boats in those areas. Some people hunt Killer Whales for sport
too or to consume the meat from them. While not very many are
killed anymore for such reasons, it is still an aspect that
takes away from the number of them remaining.
It is believed that salmon is one of their main food
sources. However, the amount of it has continued to drop over
the past decade. Some Killer Whales have been able to adapt to
other food sources in a given region. However, others haven’t
been able to do so and the result is that they aren’t
reproducing. Many of the younger members of the pods are also
dying due to starvation.
Conservation efforts can be difficult when it comes to
protecting the Killer Whales too. This is because we still
don’t know where they spend a significant period of their time
each year. Without that information we have no way of knowing
what areas need to be protected and how to do so. Additional
research is underway that will hopefully track the destinations
and so those habitats can further be looked into.
It is known that some types of traumatic events can greatly
alter the behaviors and reproduction of Killer Whales. In the
1990’s there was a huge oil spill from Exxon in areas of
Alaska. A group of transient whales from that region was almost
400 at the time and now there are only 7 remaining. There has
been no evidence to indicate this group has reproduced at all
since the incident occurred.
Whaling in the 1980’s is believed to be partially to blame
for the decline in the number of Killer Whales in the world.
The majority of these events took place in Norway and the
Soviet Union. Japan also played a huge role in this as
well.
The fact that Killer Whales don’t live very long in
captivity makes it difficult to use that a as a means of
increasing their numbers. On average, they can live up to 50
years in the wild for males and 60 years for females. However,
in captivity the average age is about 25 years. Since they
don’t mate until they are 15 to 20 years of age and the fact
that about ½ of the offspring die in the first year, there are
conservation efforts in place to at least protect these whales
in their natural environments so that they can hopefully slowly
increase their numbers.
As a result they try not to put Killer Whales into captivity
unless they would definitely otherwise die in their natural
environment. This is common when they have been injured so
captivity can at least give them a few more years and perhaps
the chance to produce offspring. More is being done though to
help extend the life of those Killer Whales that are in
captivity.
