There's a good chance that her misery is a direct result of hunger that is caused by heartless human behaviors. Why not feed the whales heartless humans and get rid of the source of the problem?
In addition, the loss of quality rearing and spawning habitat continues to take a toll on salmon populations throughout the region, where some stocks are listed for protection under the federal Endangered Species Act, he said.
Low returns of some salmon stocks prompted state and tribal fishery managers to limit opportunities in many areas to protect those fish. For example, recreational anglers will have less opportunity to fish for chinook salmon in both the Columbia River and Washington's ocean waters compared to recent years. Tribal fisheries also will be restricted in certain areas to protect weak stocks.
In meeting conservation objectives for wild salmon, the co-managers are limiting fisheries in areas where southern resident killer whales are known to feed. The adjustments will aid in minimizing boat presence and noise, and decrease competition for chinook and other salmon in areas critical to the declining whales.
The Columbia–Snake River Basin was once the most prolific salmon habitat in the world, but today its salmon and steelhead numbers have plummeted. In the 1950s, almost 130,000 adult salmon and steelhead returned to the Snake River in the spring and summer to spawn, but by 2017 that number had dropped below 10,000. Today 13 populations are listed under the Endangered Species Act, and all four salmon and steelhead populations in the Snake River Basin are at risk of extinction, according to the nonprofit Save Our Wild Salmon.
Matthews and other members of the Nez Perce tribe point to four dams on the Lower Snake River—Lower Granite, Little Goose, Lower Monumental, and Ice Harbor—as part of the reason for the decline. They worry that the fish could disappear altogether if the dams are not breached or removed.
Tahlequah the mother orca is no longer carrying her dead calf. “J35 frolicked past my window today with other J pod whales, and she looks vigorous and healthy,” Ken Balcomb, founding director of the Center for Whale Research, wrote in an email to The Seattle Times. “The ordeal of her carrying a dead calf for at least seventeen days and 1,000 miles is now over, thank goodness.”
so its not bad for them as a whole but these pods in the seattle area primarily feed on salmon where other groups have gone on to diversify their food sources and thus adapt to a wider diet
Although Orcas are not an endangered species, some local populations are considered threatened or endangered due to pollution, depletion of prey species, conflicts with fishing activities and vessels, habitat loss, and whaling.
The image tells the story of the Tlingit legend of the creation of the killer whale, which goes as follows: Natsilane was a charismatic and skilled wood carver who married the Chief’s daughter. Jealous of Natsilane’s popularity and talent, his brothers-in-law devised a plan to abandon Natsilane at sea during a traditional sea lion hunt. Left to die on a small rock in the middle of nowhere, Natsilane was summoned under the waves by a sea lion. The sea lion asked him to heal his son who was injured by a spear during the hunt. After pulling the spear point out, the Sea Lion Chief granted Natsilane great powers and helped him back to shore. Still angry about being abandoned, he began carving a great whale out of different types of wood. The first two carvings, when set in the water, simply floated away. But the third, made of yellow cedar, came to life. Natsilane sent it to exact revenge on his brothers-in-law. When the killer whale found them, he smashed their canoe and killed the brothers. But Natsilane felt badly about what he had done, and when the whale returned to him, he instructed it to never harm humans again.
so orcas mom helped her offspring kill another orcas baby so he could try to mate with her
It wasn't until the male swam past their research boat that they realized what was happening. The male had grabbed the newborn infant by its fluke and was dragging it away from its mother. Meanwhile, the male's own mother was blocking the calf's mother, preventing it from rescuing the newborn. When the newborn eventually failed to surface, the researchers knew it had been held under until it drowned. Realizing they were seeing something rare, the researchers went into autopilot, gathering as much data and recordings as possible. They say the fight ceased after the infant was drowned. No signs of feeding were observed, leading them to believe the calf was not killed as prey. Because they lost sunlight, they were unable to return for the calf's body to examine it further. The Motive Infanticide, or killing infants, has been observed in terrestrial species likes primates and rodents, but the only marine mammal species known to show the behavior are other dolphins. Towers suspects the male attacked the calf so that it could mate with the 28-year-old female. When female orcas give birth, they are unable to breed again during the period in which they nurse their offspring. What really surprised scientists was the help the male orca received from its mother.
