Learn what scientists have discovered studying the endangered Southern Resident killer whales. See the science behind recovering this charismatic creature, from collecting their poop to tracking them using satellite tags.
3:21 so basically when they are in the presence of vessel noise, the whales are like “Any salmon?!” “WHAT?!”
I seen one for the first time this summer out by steamboat Island. It was pretty incredible. It's fin had to have been 6 feet tall.
Can you in the future also possibly focus on efforts to help remove these beautiful animals from aqua parks? They do not deserve to be stuck, deprived of food, and desensitized in tiny concrete pools away from their pods for all or most of their lives just to amuse humans
Reeve You do realize that marine parks cooperate with NOAA, right? Also, that would go completely against the rules that they've put. The captive killer whales are non-releasable, so NOAA can't release them.
Unfortunately the only whale from that population alive is Lolita at the Miami SeaAquarium.
Fuck seaworld
@@namelessanonymous2090 Captive born cetaceans may not be able to be fully released, but they can and should be retired to a sanctuary. The NOAA can and damn well should partner with organizations (like Dolphin Project and Whale Sanctuary Project) that actually want to help give these animals a better and more natural life. The NOAA has been sucking the dick of marine parks for too long. They have looked the other way too often as young whales were captured, killed and exploited. Making excuses doesnt help captive whales.
Is this just the cool thing to say on every orca video? We get it, we all want captive wales treated better. They cannot be released into the wild, can’t happen. It’s about money like most things. Unfortunately no KZhead comment is going to fix that. And if you’re so against something TAKE ACTION. Words mean nothing. Action creates change.
Save these orcas very important
If it was really important they would ban commercial fishing for a couple years to replenish the food supply.
The idea of using farmed salmon to remedy this issue is absurd. Restore the river systems and the wild, natural salmon runs will recover. This is where focus should be along with run-off pollutants and shipping traffic - NOT harvested salmon. 'Americans consume a lot of salmon. Unfortunately, the majority is the unhealthiest kind. If there was ever a fish you should never eat, this is it. And for a number of reasons. The dangers of farmed fish, particularly farmed salmon, are enough to make your stomach turn. Most salmon marketed as “Atlantic” salmon is farmed, meaning fish are raised in conditions that have been shown to be ridden with pesticides, feces, bacteria and parasites. (15) It’s illegal to fish wild Atlantic salmon because they’re listed as endangered under the Endangered Species Act. In fact, even with current protections and efforts to restore the species, there’s up to a 75 percent chance U.S. Atlantic salmon could be extinct by 2100. Farmed salmon aquaculture is a huge reason the species can’t rebound, along with other issues like climate change, water pollution and water extraction. (16) Here are a other reasons inflammation-boosting farmed salmon needs to be a fish you should never eat: An October 2016 study found omega-3 levels in farmed salmon are rapidly dropping and are half of what they were five years ago. Part of the reason for the nutrient loss is salmon farm feed contains less ground anchovy content. The high demand for farmed salmon feed is causing anchovy numbers to crash, so less is now being used in salmon feed patties. (17) (This is another argument for eating lower on the food chain.) University of New York at Albany researchers found dioxin levels in farm-raised salmon to be 11 times higher than those in wild salmon. Dioxins are classified as “dirty dozen” chemicals that are stored in fat cells. Their half life is 7 to 11 years. The environmental pollutants are linked to cancer, organ damage and immune system dysfunction (18, 19) A 2011 study published in PLoS One found mice-eating farmed salmon actually showed weight gain and an increased risk of metabolic syndrome and type 2 diabetes symptoms. (20) The risk comes from the persistent organic pollutants, or POPs, that tend to be high in farmed salmon. POPs looked at in this study include organochlorine pesticides, dioxins and PCBs. A 2011 Food and Water Watch aquaculture report highlighted some concerning statistics. Hundreds of thousands of farmed fish escape into the wild. These fish are often carrying “super lice” parasitic hitchhikers that even the harshest chemicals no longer kill. Some even carry other diseases that can debilitate nearby wild fish populations. Farmed salmon have also been treated with banned pesticides, another serious toxicity concern. (21) Fish farms threaten other sea life in other ways too. And remember: Fish farms don’t really combat overfishing: they contribute to it. Salmon, for instance, are carnivores. It takes about 2½ to 4 pounds of other fish to create the salmon chow needed to produce 1 pound of farm-raised salmon. The overfishing of wild sardines, anchovies, mackerel, herring and other fish upset natural ecosystems. “We are not taking strain off wild fisheries,” agricultural economist Rosamond L. Naylor told the Los Angeles Times back in 2002. “We are adding to it. This cannot be sustained forever.” (22) In November 2015, the Food and Drug Administration approved the sale of genetically engineered salmon and will not require any labeling, leaving consumers in the dark. It was approved despite findings the GMO salmon doesn’t actually grow as fast as its creator claims. (23, 24)' draxe.com/fish-you-should-never-eat/
yearoftherat I know this is an old comment but thank you so much for compiling all this research, it’ll be very useful in trying to educate some of my family and friends
yearoftherat THANK YOU!
@@bayholeman9952 You're welcome. Farmed fish is also severely damaging to the local ecosystems they operate in. There's a reason why northern and southern resident orcas are considered the most polluted beings on the planet (look this up). If I were you, and I'm not so I have no business saying this - but will anyways, I would stay far, far away from seafood - the higher up the food chain you go the more toxins are compounded (salmon, tuna, etc). It's also important to remember Fukushima didn't just stop polluting the Pacific because the (s)news doesn't cover it. NOAA, in the end, is yet another alphabet agency with its own masters (they are under the Department of Commerce), so their idea of a remedy to this situation being farmed salmon, that will create and exacerbate a myriad of problems, is hardly surprising. I'd argue if managing our oceans was any other job they would have been tossed onto the street long ago.
@@orcawithdrip827 You're welcome.
'You could argue that by eating farmed salmon, you're not eating wild fish and not hurting these already stressed populations. Unfortunately, this just isn't true. Salmon eat other fish, so the feed given to farmed salmon is largely composed of ground-up, wild fish. This depleted the availability of food for wild salmon. One study has shown that the world's fisheries as a whole have declined since the increase in farming. Additionally, the nets made to contain farmed salmon occasionally fail, and fish escape. Once in the wild, farmed salmon are less likely to survive early stages of life. However, they grow faster; if they survive youth, they outcompete native fish later in life. The farmed salmon can also spread disease to the wild. In the Atlantic, breeding between farmed and wild fish could lead to an overall decrease in the fitness of the fish. Farmed salmon also contain more toxins than their wild counterparts since their feed contains higher toxin levels. The uneaten food, antibiotics, pesticides and feces of the fish pollute the water with both nutrients and chemicals.' - stanfordmag.org/contents/wild-salmon-vs-farmed-essential-answer www.seafoodwatch.org/ocean-issues/aquaculture/pollution-and-disease Tons of other resources for people to read. People simply need to stop buying farmed fish and maybe, while they're at it, stop buying seafood altogether and allow the oceans time to recover before the damage done is too great. There is no way NOAA or any other organization can accurately account for population numbers. On top of this, even if they could, it would go against their (NOAA) own master - the US Department of Commerce. And if anyone out there wants to have something to direct family and friends to, that's easily digestible and accessible, tell them to watch End of the Line - kzhead.info/sun/lcmdmdavomtrgps/bejne.html or Troubled Waters - kzhead.info/sun/jKV8hLKurJughJE/bejne.html Aside from the WILD salmon runs being impacted by dammed up rivers, another massive issue the resident pods are dealing with is PCB's, of which, fire retardants are massively represented. Fire retardants came about from the tobacco lobbying government to counter pressure on them from fires (people falling asleep while smoking etc.) - this is something that's not necessary and should be reversed. And it's not just them that are exposed but us as well (beds, clothing, couches, carpet, et al). www.seattlepi.com/local/article/Toxic-fire-retardants-turn-up-in-orcas-1152667.php chemicalwatch.com/72654/washington-state-eyes-action-on-toxics-for-orca-recovery
bravo selim ! you are the best!!!
Beautiful
good job!
You are an agency that could help save them. Please advice the NMFS to have a seat available for the southern residents at the table the very next time the salmon are allocated. Thanks
Watch my super pod when there were 94 southern orcas i
I have several potential factors to this decline. 1. The southern resident killer whales are potentially competing with the northern resident killer whales for salmon. The northern residents are going to many places where salmon were abundant before the southern residents do. This is from an article I read earlier and I am not biased against the northern resident killer whales. 2. All southern resident killer whales alive today in all 3 pods fall under a single clan (J clan). This contrasts to the Northern resident killer whales which have 3 clans (A,G and R). Resident killer whales tend to breed with pods from other clans to increase the genetic fitness of their offspring and to avoid inbreeding. Because of this, the southern resident killer whales are more at risk of inbreeding than the northern residents. 2 thirds of pregnancies fail because the females face birth complications related to inbreeding. The southern residents have a low breeding output because many of the whales who are potentially inbred are less fertile as a result. Many calves die young because their potentially inbred nature means their genes are less resistant to disease and pollution.
godbless you
Fantastic
Yet no mention of PCB's
lets hope j35's calf doesnt die this time, still looking meager for the southern residents
At no point in recorded history has there been 200, actual an increase since 1960. Reduce the number of ever expanding seal and sea lion populations and restore our rivers and spawning habitat.
And put the transient orcas under stress...what a moronic thing to say! Killing one species to save another isnt the answer. Get rid of those dams that block spawning groundss and thats how you save the SRO!
I notice that nothing is said about the 40,000 seals in their area eating salmon as well competing directly with the killers. It would be interesting to see the graph showing the decline of killers overlaid with the boom of the population of seals maybe its nature herself killing them off.
while Salmon are their main source of food, the other portion includes seals...
@@richardvsassoon5144 OMG. The Southern Residents DO NOT EAT SEALS! They supplement a winter diet with other fish, but prefer salmon. They have never been documented eating marine mammals.
The southern resident orcas aren't the only population in the area. Transient orcas are also in the Pacific Northwest and those orca do feed on seals and sea lions. In fact the transients have been growing in size and are actually becoming more frequent and stay longer because of how much food is now available to them. It's annoying when people think there's too many of some kind of animal as if humans have nothing to do with the messed up food chain in this region..
In contrast to the ailing southern residents however, the transients (increasingly known as bigg’s killer whales) have been thriving in recent years. Scientist estimate over 350 bigg’s killer whales in the Salish sea alone.
They said so in the video that a large reason why the population plummeted, was a combination of the live captures, which took out healthy, young animals that otherwise would have contributed genetically to the pods, pollution and loss of Chinook salmon. Got nothing to do with the seals.
Ok I know they are members of the dolphin family since they have teeth, but are they related to whales also?
Hi James. You are correct. Dolphins and killer whales are in the same cetacean family (Delphinidae), and are technically considered “small whales.” The mammalian order Cetacea is divided into two main groups: 1. the Odontoceti (toothed whales) 2. the Mysticeti (baleen whales) All the various species of cetaceans (whales, dolphins and porpoises) - from the massive blue whale to the tiny harbor porpoise - are scientifically classified as “whales.” The term “whale” is used colloquially to describe species of cetaceans that are typically larger than 12 feet, such as pilot whales and killer whales (technically species of dolphins), sperm whales (the largest species of toothed whales), and all the baleen whales (e.g., right whales, humpbacks whales, blue whales, etc.).
Txtin 🥺🥺🥺🥺🥺🥺
First and foremost is get the Chinook runs on the Fraser back up. Canada needs to understand their role. B.C. needs to stop pumping raw sewage into Puget Sound.
VERY GOD
Orcas are mammals not fish 🐈🐈🐈🐈🐈🐈🐈
Do killer whales ever fight each other??
Don't look so to me
Serious fights are extremely rare for wild orcas. Little ones are sometimes disciplined but nothing serious.
i think both US & Canada gov should ban ships that using sonar from entering the area where southern resident orca live & travel. Apart from that, clean the river from any contaminants & try to breed chinook salmon in that area so southern resident orca will have enough food to eat, they're starving! help them before our future generation could only study southern resident orca from books
❤ :)
5:01 i'm not an expert but i could definitely tell that the calf is starving, the shape of its head is different from normal orcas
Thats a newborn calf. Her head shape is normal.
HD Audios Z
05:00 the calf appeared malnourished
Looked like Scarlet
WEARETHEORCAS petition bracelets etc etc ......
Did you notice he said "historical estimates." No one knows the "right size" of the Southern Resident Killer Whales.
Good luck preventing the US navy from doing them harm.
What does the Navy have to do with this
They’re not whales yet you keep calling them whales
thats cause they are called killer whales, and that what ppl know them as, and this vid is mad to the public, most ppl don't know that killer whales are named orcas, and are closer to the dolphin then the whale.
