Latest / How To Protect The Ocean / Are These Whales Doing Better?
Transcript
- 0:00For the first time in years, the North Atlantic right whale
- 0:02population has stopped shrinking.
- 0:04Scientists have estimated about 372 individuals that remain up
- 0:08slightly from previous years.
- 0:10It's this fragile sign of hope for one of the ocean's, most endangered giants.
- 0:15But before we celebrate too quickly.
- 0:18We need to ask ourselves, what does this mean?
- 0:21The small increase mean for this population?
- 0:24Are right whales finally rebounding, or are we just
- 0:27buying them a little more time?
- 0:29We're gonna talk about that on today's episode of the How
- 0:31to Protect the Ocean Podcast.
- 0:33Let's start the show.
- 0:36Hey everybody.
- 0:36Welcome back to another exciting episode of the How to Protect the Ocean Podcast.
- 0:39I'm your host, Andrew Lewin, and this is the podcast where you find
- 0:42out what's happening with the ocean, how you could speak up for the
- 0:44ocean, and what you can do to live for a better ocean by taking action.
- 0:49And on today's episode, we're gonna be talking about the endangered population
- 0:52of the North Atlantic white whale, which sits in the North Atlantic.
- 0:55in the winter, it goes down to Florida in the summer, it goes all the way
- 0:57up to the northeast coast of the US and now into the southern part
- 1:02of the Gulf of the St. Lawrence.
- 1:03We're gonna talk a little bit about that and why that is partly contributed to
- 1:07their decline in the 2010s, but we're gonna talk about a population, think about
- 1:11whale populations before whale hunting existed, like real whale hunting existed.
- 1:17'cause you gotta remember, whales were hunted for oil.
- 1:19They were hunted for energy.
- 1:20That's how we got oil and that's how we were able to light candles and have
- 1:24basically light at night, essentially.
- 1:26So whales were a big part of that energy.
- 1:28That's how we kept warm, all that kind of stuff.
- 1:29And so before that, the populations of the North Atlantic right whale was between
- 1:339,000 individuals and 21,000 individuals.
- 1:36Imagine that.
- 1:379,000 and 21,000.
- 1:38Here we are celebrating 372 individuals.
- 1:42So think about that when you look at the entire context.
- 1:45Now as whale hunting happened, a lot of whales decreased.
- 1:50Like to the point, some went extinct, some near extinction, and some almost right.
- 1:55And then we have a rebound.
- 1:56We have the moratorium on whale hunting.
- 1:59And then in the 1980s there was like low hundreds and
- 2:02recovering from the whale era.
- 2:04So like, you know, you're looking at a couple hundred, which we
- 2:06don't know the exact number 'cause they're really hard to find.
- 2:09They're really hard to monitor.
- 2:10They like to stay just below the surface.
- 2:12And so it makes it really difficult to see if there's an animal there or not,
- 2:16especially when you're doing in the 1980s, you're not using radar, you're
- 2:19not looking at heat signals and so forth.
- 2:20Or we're not doing aerial surveys as much.
- 2:22And so in the 1990s we saw growth.
- 2:24We saw 200 to 400 somewhere in that region.
- 2:27So growing slowly, the population increasing a little bit more
- 2:30similar to what it is today.
- 2:32You know, growth rate about two to 3% from 1990 to 2007.
- 2:36Then around the 2010s, we were looking at 480 to 500 individuals.
- 2:41The peak estimate before the decline that we have been seeing over
- 2:44the last, you know, 10, 15 years.
- 2:47Then in the 2010s, we had another decline period, so about 25 to
- 2:5030% decline from 2010 to 2020.
- 2:53Essentially going down to below, you know, the three fifties.
- 2:58And that's obviously not good.
- 2:59And the reason that happened is we started to see a shift in the population.
- 3:03Now, before we go that, let's talk about why these animals are declining.
- 3:07When decline happened, or pre 1980s during the whale hunting, it was whale hunting.
- 3:11That's what was killing these animals.
- 3:13Now between 2010 and 2020, it was a decline due to two things.
- 3:16It was ship strikes, or it was traps, like got caught in lines
- 3:21because of lobster traps, crab pot traps, whatever it might be.
- 3:25These are fishing devices that were getting bottom dwellers,
- 3:29you know, bottom invertebrates, like crabs and lobsters and such.
- 3:32And so what happens is they take these pots, right, these traps, they stick
- 3:36lines to them, and then they put 'em in the water and they sink 'em.
- 3:40And then the lines will be attached to buoys.
- 3:42And the buoys will kind of give away the position for the fishermen to come
- 3:45back and grab the buoy and then be able to bring up the pot or the trap when
- 3:50it's time to get 'em and you get all the animals that are in it and you can
- 3:53take 'em back and you can sell them.
- 3:54Especially on the northeast coast of the US that's a huge thing.
- 3:57Even in Canada, lobsters, crab, that's a big part of the fisheries.
- 4:01There's big unions for it.
- 4:02There's a big fishery for it, and you know, it's a lobby for
- 4:05it as well because they wanna protect their interest in fishing.
- 4:08And especially after the cod dropped and the moratorium on cod
- 4:11happened, and we saw haddock fall.
- 4:13We saw a lot of other fish fall.
- 4:15It was very difficult to find something that was good.
- 4:17So having these invertebrates, these lobsters were just boom because
- 4:19less fish that would eat them.
- 4:21You're starting to see a boom in population, especially
- 4:23lobsters, crabs and so forth.
- 4:24So they were fishing for them.
- 4:26Now with that said.
- 4:27You have two destructive things that are happening to these animals.
- 4:30You get ship strikes, which it basically means these animals are coming in.
- 4:33And remember when I said the whales stay right below the surface for
- 4:36the North Atlantic right whale.
- 4:37The boats can't see them.
- 4:38They come in, they hit them, either they have a big cut on them or they're
- 4:42bruised really badly or hit really badly.
- 4:44Think about getting hit by a boat.
- 4:45You know, just imagine that.
- 4:46And some of these are major, major ships, like these are transport vessels.
- 4:50So they're like, four or 500 feet.
- 4:51They're moving quite fast and they're not gonna be able to move last minute
- 4:55to be able to avoid a ship strike.
- 4:57And so these animals either end up dying of their injuries or they die right away.
- 5:01You've seen some images of ships coming in and the whales still being
- 5:04on the ship which is devastating.
- 5:06Nobody wants to see a whale pass away that way.
- 5:08Nobody wants to see anything pass away that way, let alone a whale.
- 5:11So, there's that problem, Then you have the crab pots, they're swimming
- 5:14through the lines and they get the lines.
- 5:18Caught on their fins, and that line digs in.
- 5:20They can't take 'em off.
- 5:21They don't have the appendages to take them off.
- 5:23And they can't get their mouth over there to take 'em They have these
- 5:26cuts along the lines where their fins attached to their body, and they start
- 5:29to get cuts and infections and they eventually die from their wounds, or
- 5:33they just get entangled where they can't move and they end up drowning.
- 5:36It's, again, not a good way to go.
- 5:38And so there have been mitigation measures for both of these things.
- 5:41Now in the summer of 2017, we really saw a decline.
- 5:44We saw about 17 individuals die up in the Gulf of St. Lawrence,
- 5:49not all 17, but most of them were, those are the only 17 that we found.
- 5:52We found over the summer that 17 animals died, there's a huge monitoring
- 5:55program that's been out since the 1980s and maybe even before to monitor
- 5:59this populations, 'cause it's been on the endangered species list.
- 6:02And so when they saw the decline again, they were worried.
- 6:04They remapped the shipping tracks so that ships wouldn't get into them.
- 6:08And this is in the northeast.
- 6:09And then we saw, you know, changes in where you can fish
- 6:13based on where the whales are.
- 6:14As I said, monitoring programs know where these whales go.
- 6:17They know their migration patterns.
- 6:18If you stay away from that and the shipping lanes stay away from those areas,
- 6:22then we should be okay, for the most part, should decrease the amount of strikes.
- 6:26In 2017, though, we saw a shift in the migration and the distribution
- 6:30of these whales into the Gulf of St.
- 6:33Lawrence where these animals started to pop up.
- 6:36Now, with that said, is.
- 6:37These ships were not ready for these animals to pop up.
- 6:40They're moving at 20 knots.
- 6:42And when you're in these shipping lanes or you're in these areas where
- 6:45these animals are supposed to be the North Atlantic right whales, you
- 6:47should go down to about 10 knots.
- 6:49And so before we even discovered that there were a good number of these
- 6:52animals, a few got tangled in crab pots or lobster lines unfortunately.
- 6:57And so they weren't ready for that from a management perspective.
- 7:00So mitigations went in temporarily and we saw a decrease of these
- 7:04strikes and these entanglements that we saw, that we discovered.
- 7:07You have to remember that a lot of these North Atlantic white whales.
- 7:09We don't see what they could be.
- 7:11So like, just as much as the estimates could be low or the fact that
- 7:15there could be a higher death rate.
- 7:16Also back before 2010 when we saw the 400 8500 numbers, there could have been more.
- 7:21We just didn't see them.
- 7:22They're a little bit elusive when it comes to a massive animal, believe it or not.
- 7:26And so it's difficult to find out how much there actually are, but
- 7:29we kind of know the overall trend.
- 7:31And we've hit the low point in the early 2020s, around 356 to 358.
- 7:36With new studies, we're starting to see that this population is
- 7:38up a little bit slightly to 372.
- 7:41We've seen a slight increase doesn't mean that the population is rebounding.
- 7:45It just means what we're doing in terms of mitigation works right now, for now.
- 7:50This is what we've discovered.
- 7:51It could just be a summer.
- 7:52We haven't really found them.
- 7:53If animals have died or they've sunk down to the bottom of the ocean,
- 7:56so we may not have found them.
- 7:57The fact is we just found more of them.
- 7:59There's more effort to find them.
- 8:01Who knows?
- 8:01Right?
- 8:02So now we have slight increase, which is a good news.
- 8:05This is positive news.
- 8:06It should be celebrated, but also we shouldn't rest here.
- 8:09This is just the beginning.
- 8:10Just like I talked about the green sea turtle last week a couple of episodes ago.
- 8:14You know, this is great.
- 8:15It was great news to see that they're not endangered, They're just vulnerable.
- 8:19At least vulnerable, I think is what their level is.
- 8:22And that's great to see.
- 8:23But, we still have a lot of work to do because they could just go back down to
- 8:27endanger just as easily if we slightly lift some of the mitigation factors or
- 8:32mitigation measures, like things that we do to protect them up a little bit, or
- 8:36we don't go full throttle on protection.
- 8:38We need to continue the protection so that we see that trend
- 8:41get more and more positive.
- 8:42That's what we're looking for here.
- 8:44So we'd like to see even higher numbers next year in the estimate.
- 8:47Luckily, there are great research programs that are going on.
- 8:50There's a lot of nonprofit organizations, the government's involved in the US
- 8:53and Canada to monitor these animals.
- 8:55There's a lot of private consulting that are monitoring these animals
- 8:58because we wanna make sure that we are protecting them.
- 9:00That is an important aspect to what we are doing here for these animals.
- 9:04And so the monitoring programs are in, hopefully the money remains in.
- 9:07For monitoring these animals.
- 9:09We're gonna see what happens in the states.
- 9:10We know there's a lot of cutbacks.
- 9:12Hopefully Canada can make up for it on the north side of the border.
- 9:15But this is what we're looking at.
- 9:16This is a celebration that there has been a first year in a while where there's been
- 9:20an increase and not a decline, and that maybe these things are starting to rebound
- 9:25into something a little bit better.
- 9:27Monitoring needs to stay.
- 9:28We need to continue to make sure that we are doing all the
- 9:31mitigation measures that we have to.
- 9:33We are looking at lobster pots and crab pots, traps, whatever you want to call
- 9:37them to be mindless, meaning that they go down in the water without any lines.
- 9:42They catch their lobster or crabs, and then the fisher just kind of
- 9:45presses a button and it blows up these balloons and they float to the top.
- 9:49Is it perfect?
- 9:50No.
- 9:51But is it starting to get better and better?
- 9:52The technology's starting to get better and better.
- 9:54Yes.
- 9:54And we're starting to see more experiments and, more fishers are
- 9:58getting involved and trying these things.
- 10:00Now.
- 10:00I know the initial experiments didn't go the way the fishers want.
- 10:03It's very difficult.
- 10:04Sometimes they didn't work and all that kinda stuff.
- 10:05But as we continue to improve the technology, we'll get better and
- 10:09better and hopefully we'll never lead lines again and we don't have
- 10:12to worry about entanglement for a lot of these whales and other animals
- 10:15like sea turtles and so forth.
- 10:16And we'll see better protections with those and increase phishing yields if
- 10:19that's needed, hopefully managed well.
- 10:22but provide the fishers with the income that they need to survive.
- 10:25That's essentially what we're looking here for the better compromise.
- 10:27So, we can mitigate shipping lanes, we can change those up as we need, but
- 10:31we also need the monitoring because climate change is one of the factors in
- 10:36changing the distribution of these whales.
- 10:37We're gonna see that in fish.
- 10:39We're gonna see that in plankton, which is why probably these animals, these
- 10:42North Atlantic white whales have probably shifted north ' cause the plankton have
- 10:45shifted north and what they like to eat.
- 10:47And so we're gonna see animals shift and we need to continue monitoring
- 10:50that so that we can mitigate
- 10:51any kind of disasters, like a disastrous summer from 2017.
- 10:55We don't want a repeat of that.
- 10:56So we have to act fast.
- 10:58We have to adapt to the distribution.
- 11:00We have to monitor, monitor and adapt.
- 11:02That's the big thing.
- 11:03And continue to manage these animals and hopefully we'll see a bigger
- 11:06increase next year and then the year after that, and the year after that.
- 11:09And we just continue, even if it's slight every time I'll be happy with
- 11:12that as long as it goes in the positive.
- 11:14These animals are slow growing.
- 11:16They don't reproduce very much over the summer.
- 11:18It's one calf per female every summer.
- 11:21If we can get that, if that, probably not, it's probably a lot
- 11:24lower than that at this point.
- 11:25But if we can get to very close to that, that would be great.
- 11:28We're not gonna get close to that anytime soon, but as the animals
- 11:31get healthier and as there's less indirect or direct effects on them.
- 11:34Then maybe we can see that growth even better.
- 11:37There's a probably, I think it's under 90, maybe even 80 reproductive females,
- 11:41so that needs to increase as well.
- 11:43So I think there were 12 calves this year, which is great.
- 11:46Which is great to see.
- 11:47I feel like they're still alive so far, so that's great.
- 11:50That's great news.
- 11:51Great news all around.
