A century ago parts of the sea were teaming with whales. But human intervention changed this. The commercial whaling era killed millions of whales and made them into lamp oil, lubricants, cosmetics, and meal. Today, some whales are barely recovering from the whaling industry, while others have increasing numbers. But they face so many dangers other than whaling: pollution, loss of food sources, loss of habitat, climate change, toxic substances, being entangled in or ingesting plastic, sonar testing, net entanglement, trapped as incidental by-catch of the fishing industry, and ship strikes are some of the dangers killing whales.However all these reasons all come back to humans

1. Blue Whale - 9,000

Bowhead Whale - 8,200

Bryde's Whale - 66,000-86,000

Fin Whale - 123,000

Gray Whale (eastern Pacific stock) - 21,000

Gray Whale (western Pacific stock) - 100-200

Gray whale (Atlantic stock) - Extinct

Humpback whale - 25,000

Sei whale - 55,000
Minke whale -unknown- but tens of thousands were killed during whaling era 850,000

Northern right whale -unknown- but tens of thousands were killed during whaling era 870-1,700 in the western Atlantic; very few in the Pacific.

Southern right whale- no estimate- but 40,000 were killed .

2. North Pacific Right Whale, North Atlantic Right Whale, Blue Whale

What he/she means is that the whales in the North Pacific and North Atlantic and the blue whales are endangered because either they can't find enough food, or they are being illegally hunted

3. Three to fifteen whales are endangered.

As you can see the Gray Whale (western Pacific stock
Is extinct so that must mean the whale was hunted the most out of all of the whales on here.

By Mia

Anonymous said...

Between 10,000 and 25,000 blue whales.

Right whales are the rarest of all large whales.

Maya said...

the right whale was caught a lot
in the years when whaling was not banned.

Lyndon said...

1.Humpback whales currently number only 20,000.
A 2002 report estimated there were 5,000 to 12,000 Blue Whales worldwide.

2.Vaquita and Baiji are the most endangered species of whale.

5.Powerful underwater sonar creates tissue-destroying gas bubbles in the vital organs of whales and other marine mammals, causing a fatal sickness similar to the bends that deep-sea divers undergo when they surface too quickly.

The new annual quota for minke whales is lower than that count 120 kills per year.

Greta said...

Here are the answers to my questions:

.West pacific grey whales are near to extinction with only around 100 left in the worlds oceans.

.The main countries that hunt and kill whale are Japan,Iceland and Norway.

.The Northern Right whales population is unknown but thousands where killed in a whaling era.

.Whaling has been around since 3000 BC

.In the late 1930s more than 50,000 where killed annually.

.All the catches between 2003-2007 where Bowhead whales and altogether there were 216 bowhead whales killed.

-Japan has killed 8,201 minke whales in the Antarctic for “scientific purposes” since the moratorium in 1986. A total of 840 whales were killed by Japan under special permit during the 31 years before the moratorium1.

In 2006/07 Iceland took 60 minke whales under special permit for "scientific whaling", up from 39 in the last season1.

Here are some facts...........

Before whaling began it is believed there were 250,000 blue whales - the Earth's largest mammal. Today the estimate is between 500 and 1,000.

* How many species of whale are there?
81 species found worldwide
* What is the most endangered whale species?
West Pacific grey whale population is the most endangered in the world
* Where are whales mostly caught?

Maya said...

There are diffent levels of endangerment.-Extinct (EX) - No individuals remaining.

Extinct in the Wild (EW) - Known only to survive in captivity, or as a naturalized population outside its historic range.

Critically Endangered (CR) - Extremely high risk of extinction in the wild.

Endangered (EN) - High risk of extinction in the wild.

Vulnerable (VU) - High risk of endangerment in the wild.

Near Threatened (NT) - Likely to become endangered in the near future.

Least Concern (LC) - Lowest risk. Does not qualify for a more at risk category.Widespread and abundant taxa are included in this category.

Data Deficient (DD) - Not enough data to make an assessment of its risk of extinction.

Not Evaluated- (NE) - Has not yet been evaluated against the criteria.

The blue whale is endangered, that is the fourth level.

dorrie said...

Biggest blue whale ever recorded was ~110 feet (33m). You and 400 of your friends could fit in its mouth. Blowhole is large enough for a baby to crawl through.

It is estimated that there are about 8,000-14,000 blue whales worldwide, which makes them an endangered species. These whales (and many other large whales) were over-hunted for many years, since their meat, oil, and other body parts are very valuable. Since whale hunting has decreased in the last few decades, their populations are starting to recover.



o Before whaling: About 275,000 (Kemf & Phillips 1994)

o 1930's: 30,000 - 40,000 (IUCN 1966)

o 1962: 930 - 2790 (IUCN 1966)

o 1964: 650 - 2000 (Oryx 1964a)

o Late 1970's: 4000 - 4500 (Burton & Pearson 1987)

o 1980: About 6500 (Nowak & Paradiso 1983)

o 1990: 2500 - 3000 (Klinowska 1991)

o 1994: Probably under 5000 (Kemf & Phillips 1994)

1,170,100 whales are left in the world

The North Pacific Right Whale is currently known as the world's most endangered species of whale

For unknown reasons, killer whales have a high calf mortality rate in some areas of the world. In the Pacific Northwest, for example, 43% of all calves die in the first six months.
In the late 1930s more than 50,000 where killed annually
whales are mostly found in the the oceans and these animals aren't located
"mostly" in any one place

* Minke whales are probably the whales most targeted by the Japanese. Recent estimates show there could already be as few as 250,000 Minkes from 3 different sub-species in the Southern Ocean, despite Japanese claims of close to 1 million.
*A lot of the legitimate science is disputed by Japan which comes up with its own (dubious) figures to justify the supposed sustainability of a continued kill. They also argue it is a cherished cultural tradition for Japanese people to keep killing whales - However a recent Japanese Newspaper poll found only 4% of Japanese regularly eat whale meat. * Massive industrial-scale Antarctic whaling 10,000 km from Japan is definitely not a tradition and only began around World War II when whale stocks around Japan were already commercially extinct (unviable for continued hunting). Whales were initially targeted by the Japanese for oil as a source of foreign currency!
* A global anti-whaling movement began in the 1970’s, with the hope of saving some of the species of whales that had become in danger of extinction due to the increased whaling by many countries. In 1972, the United Nationals Conference on the Human Environment at Stockholm put forward a proposal that recommended a ten year moratorium on commercial whaling to allow the whale stocks to recover.But,even now,some countries like Japan,still hunt and kill hundreds per year.

Whaling began in prehistoric times and was initially confined to (near) coastal waters. Early whaling affected the development of widely disparate cultures—such as Norway and Japan.Although prehistoric hunting and gathering is generally considered to have had little ecological impact, early whaling in the Arctic may have altered freshwater ecology.The development of modern whaling techniques was spurred in the 19th century by the increase in demand for whale oil, sometimes known as "train oil" and in the 20th century by a demand for margarine and later meat.

Mr D said...

Wow! I'm really impressed with the research a lot of you have been doing over the past week. These whaling facts sure have been useful for our argument writing. These low whale numbers are seriously alarming!

Olivia L said...

Whaling is the hunting of whales mainly for meat and oil.

As technology increased and demand for the resources remained, catches far exceeded the sustainable limit for whale stocks. In the late 1930s more than 50,000 whales were killed annually, and by the middle of the century whale stocks were not being replenished. In 1986 the International Whaling Commission (IWC) banned commercial whaling so that stocks might recover.

Further research in 1995 and 1996 shows significant drop of non-minke baleen whales sample to 2.5%.[34] In a separate paper, Baker stated that "many of these animals certainly represent a bycatch (incidental entrapment in fishing gear)" and stated that DNA monitoring of whale meat is required to adequately track whale products.
