Re: Right Whales

I have only watched the trailer to this video. The trailer only contains comments from US fishermen & activists.
I hope the full film contains the same from the Cdn side.


I post Right Whale info to inform boaters of non-boater/general public's reaction to the plight of Right Whale & other marine creatures.

The general public are a much larger voting block than waterfolk.


Jus sayin. / Len

Re: Right Whales

The first North Atlantic right whale of the season, has been sighted northeast of the Magdalen Islands, in the Cabot Strait, triggering an early, and localized, snow crab fishery closure, in the Gulf of St. Lawrence.
This sighting has triggered a 15-day fishing closure, three days ahead of the April 28 start date for scheduled measures [automatic fishery closures, & shipping-lane restrictions] to protect them, in crab fishing area 12F, east of the Magdalen Islands.

Right whales migrate each spring, from the waters off the southeastern U.S. to Canadian waters, including the Bay of Fundy and Gulf of St. Lawrence.
The lucrative snow crab fishery is fully underway, in the Gulf of St Lawrence. In recent years the season has opened early, in an effort to catch more of the quota, before the whales arrive.

Ship strikes, and entanglements in fishing gear, are the two leading causes of death in right whales. Since 2017, 20 of the whales have died in the Gulf of St. Lawrence.
No right whales died in Canadian waters in 2018 and 2020.

In recent years, Ottawa has closed fisheries when right whales are spotted in an area and imposed ship speed limits in the gulf during the months when they are present.
This year, when a right whale is sighted, an area around it is closed to fishing for 15 days. If a second sighting occurs during days nine to 15, that area will be closed until November.

Researchers estimate fewer than 400 right whales survive, with fewer than 100 breeding females left.
Currently, dozens of North Atlantic right whales are congregating near Cape Cod, Mass.

Re: Right Whales

This is about Calif. coast Humpbacks,turtles,etc.
Big move for Calif. to close crab fishery as Atl. Canada does.
Note "inside 30 ftm-no whales"-which is what Atl. coast observes.
Note "ropeless gear-not workable yet"

The gear's origin is unknown, said the release.
Surely it must be evident what type of gear it was.

I know journalists aren't going to ask detailed questions like this, but you'd think the researchers issuing the statement would know it's important.

How are we going to avoid these entanglements if we don't even know which fishery is responsible? Oh, that's right. Close all fisheries. Simple.

Re: Right Whales

North Atlantic right whales are smaller now than they were 40 years ago

Decades of data [1] shows today's average whale is a metre shorter than it was in the 1980s.
The big thing that the researchers found, were that whales that have these extended entanglements, that last for months or years, are stunted, compared to whales that aren't entangled.
Most North Atlantic right whales become trapped in fishing nets and traps, at some point in their lives.
Over 85 per cent of the population has entanglement injuries, either scars or attached gear, so it's a pretty chronic problem for this population.
There's a good chance other whale species, that are often ensnared, are experiencing a similar decrease in size. But as North Atlantic right whales have been on the brink of extinction for so long, they're one of the few species with such a detailed data set, dating back decades, that researchers can use to prove it.
Using weaker ropes for fishing would give whales a better chance at freeing themselves. Better yet, getting rid of ropes altogether, using ropeless traps, would prevent whales from getting caught in the first place.
If the whales were given the chance to recover, the species would eventually return to its normal size.

Re: Right Whales

And every one of those ships have an AIS displaying their current speed on Marine Traffic.com. Where is the CG??
https://www.nationalfisherman.com/na...pZrz2Kmp_5H06k


The 10kt speed limit is voluntary! in USA.

According to deblen's linked article:
Since 2017, 33 right whales have been killed, according to NOAA. Of those, 21 were in Canada and 12 were in the United States. Ten of the 12 domestic incidents — 83 percent — were attributed to ship strikes. None can be linked to the Maine lobster industry.
https://www.nationalfisherman.com/no...-gets-it-wrong

That may depend upon who, and/or when you ask the question.

According to the US Marine Mamal Commission:

Since 1970, nearly half of all documented North Atlantic right whale deaths have been due to two human-related causes—ship strikes and entanglements in fishing gear. Ship strikes were the major known cause of death before the mid-2000s. After management measures were implemented between 2006 and 2008 to reduce ship strikes, deaths due to this cause have decreased significantly. However, at the same time, deaths due to entanglement have increased significantly despite management actions that began in the late 1990s. Entanglement is now the most significant known cause of right whale mortality.

More ➥ https://www.mmc.gov/priority-topics/...c-right-whale/


According to the Clear Seas Centre for Responsible Marine Shipping:

Two per cent of the North Atlantic right whale population lost in two months

In 2017, twelve North Atlantic right whales washed up along the shores of the Gulf of St. Lawrence and Newfoundland; an unusually high number of deaths for such a small population. Only six necropsies could be conducted as six of the carcasses could not be examined and their cause of death remains undetermined.
Two of the whales had acute entanglement with fishing gear; reports for four of the whales indicated that blunt force trauma contributed to their deaths, which likely came from collisions with ships.
In 2003, shipping lanes were rerouted in the Bay of Fundy to reduce the potential for ship collisions. It is estimated that the rerouting measures reduced the potential for ship collisions with right whales by 90%. However, as the whales have been appearing over the past years in the Gulf of St. Lawrence, scientists speculate that the whales may be shifting away from their traditional habitat to follow their food source.
Every year, since 2017, seasonal protective measures have been implemented in the Gulf of St. Lawrence to help prevent ship strikes, entanglements, and to reduce the effects of underwater noise from ships.

More ➥ https://clearseas.org/en/blog/endang...SAAEgLayfD_BwE

BUT
According to Oceana Canada:

Unfortunately, entanglements are becoming all too frequent for North Atlantic right whales. It is estimated that 100 right whales are entangled each year. An astounding 85 per cent have been entangled at least once, and more than half have scars from multiple interactions with gear. In addition to the known entanglements, it is likely that some whales die during or shortly after becoming trapped and are never seen again.
Entanglement in fishing gear, ropes and other marine debris is not an exclusive problem to North Atlantic right whales. The International Whaling Commission estimates that 300,000 whales, dolphins and porpoises worldwide die from entanglements every year. This is the main human-induced threat to large whales.
