The Sunshine Coast Daily reported Strong northerlies blowing through the summer have contributed to the problem with a Surf Lifesaving Queensland spokeswoman advising Noosa and Mooloolaba recording the most stings with approximately 3000 each.

– NOAA: Young herring “suddenly disappear” from Pacific, no one can find them; “This is an enigma, something’s happened” — Millions of missing salmon raising alarms; “Very odd… Very strange… Most different year ever… It looks really bad” — Fishermen catching only huge numbers of jellyfish (VIDEO) (ENENews, July 6, 2015):

Bristol Bay Times, Jul 3 2014 (emphasis added): [T]he sluggish start to a large forecast run was making many people in the industry restless… Naknek-Kvichack district’s run total was about 434,000 sockeye – less than 2 percent of this summer’s expected run of 28.8 million… on the same date in 2014 [it] was already nearly 5 million… Elford saw just one fish hit a net all morning. They were, however, catching jellyfish by the hundreds. Elford says this is strange timing, as jellyfish… signal the end of salmon season.

Alaska Dispatch News, Jul 2, 2015: [Kuskokwim River salmon] returning to spawn is still alarmingly low… [Kings are] dramatically below last year’s count… “Mounting evidence suggests that the 2015 chinook salmon run was early and weak,” Fish and Game managers said… chum salmon also is very low, the Bethel test fishery shows… “The chum salmon run is showing so poorly” [a state biologist] said…”comparable to 1997, which was one of our crash years… It looks really bad.”

Maybe The World’s Only Immortal Animal

by

The turritopsis nutricula species of jellyfish may be the only animal in the world to have truly discovered the fountain of youth.

Since it is capable of cycling from a mature adult stage to an immature polyp stage and back again, there may be no natural limit to its life span. Scientists say the hydrozoan jellyfish is the only known animal that can repeatedly turn back the hands of time and revert to its polyp state (its first stage of life).

The key lies in a process called transdifferentiation, where one type of cell is transformed into another type of cell. Some animals can undergo limited transdifferentiation and regenerate organs, such as salamanders, which can regrow limbs. Turritopsi nutricula, on the other hand, can regenerate its entire body over and over again. Researchers are studying the jellyfish to discover how it is able to reverse its aging process.
