There is absolutely nothing wrong with eating bluefin tuna

with one comment

A comment “for the ages” by reader David Schalit after a curious NYT environmentally ambiguous piece:

There is absolutely nothing wrong with eating bluefin tuna.

Bluefin is a delicacy, not usually eaten as steaks. It is usually three small slices, certainly no more than five or six, on a plate containing three or four species of fish.

In the controversies surrounding fishery management and questions of species abundance in the US and Europe, environmental organizations may tend to overstate the issues, and for very good reason: Environmental organizations are essentially lobbyists and mostly depend on public donations for their livelihood. Therefore, they tend to overstate in order to attract the attention of the public to a given issue. And that is precisely how public opinion has been shaped on the issue of bluefin.

Anyone who reads the news knows that these days NOAA is not considered a compliant partner of US fishermen. NOAA’s decision to not place Atlantic bluefin under protection of the Endangered Species Act at the end of May 2011, was not a capitulation to the bluefin fishermen, but an historic decision based upon exhaustive study undertaken over 12 months and involving US and European scientists and fishery management specialists both inside and outside of government. Some of the best minds in bluefin science had input into this exhaustive process. There is no doubt that if NOAA had any way of validating the probability of extinction or even the threat of extinction, they would have listed the bluefin under ESA. The simple fact is that there is no creditable pelagic scientist who will sign their name to a statement saying that Atlantic bluefin is, 1/ endangered with extinction, 2/ threatened with extinction or, 3/ near [or “on the edge of..”] extinction.

As to the issue of commerce driving the bluefin to extinction, we can thank the media for this misunderstanding. There are no US bluefin fishermen who have Mercedes parked in front of their homes. Practically every article written on bluefin never fails to mention that bluefin sells in Tokyo for upwards of $150,000 “for one fish”. It is amazing to me that journalists have never even bothered to check on this. Auction data from Tsukiji Market for bluefin is available every day online. US bluefin fishermen receive approximately $4-8/lb for their fish, less than they would get if they fished for scallops. The US bluefin fishery is a small, artisanal fishery in which the fish are caught sustainably using hand techniques. The Pew has recently validated this statement. No industrialized fishing methods are allowed. Each vessel is a sole proprietorship, owned by its captain. The US bluefin artisanal fishery is the most highly regulated bluefin fishery in the world. The limit per day in season is three fish and the minimum size must be 73”. A fisherman would be very lucky to catch three fish in one day. It is true, however, that once every year or so, usually in Dec or Jan, an Asian restauranteur dramatically bids up the price of one bluefin at Tsukiji Market as a publicity stunt and this is what finds its way into the media.

As microblogged live on my (other) Twitter account, @mmorabito67 on May 25, 2011:

  1. At the BIS British Interplanetary Society in London for Alan Lawrie’s SaturnV presentation. live microblogging 6pm GMT
  2. Title is “Saturn V Manufacturing and testing” – room packed
  3. Special anniversary of Kennedy’s announcement of the Moon attempt in 1961
  4. Lawrie has 30 years of space technology experience
  5. Kennedy spoke at around 1.09pm EDT – Also 45th of first full rocket
  6. Mastermind was Von Braun – developed in record time, new materials invented
  7. Huntsville Al. was a small city when Von Braun went there in the 1950s –
  8. Picture of Von Braun team member meeting Korolev’s daughter –
  9. Saturn was a military concept for testing rockets at the start –
  10. Pictures of Marshall Spaceflight Center test facilities –
  11. RL10 h2 / o2 rocket test facility. Neosho rocket production facility in Missouri near Joplin –
  12. Details of rocket. First stage S-1C by Boeing and MSF.
  13. Welded tanks but bolted intertanks. Manufacturing details. Fairings around external engines blown after separation
  14. Pictures of retrorockets firing – heroicrelics.org
  15. S-1C firing test at MSF. Walt Disney visiting Huntsville
  16. Picture of Saturn V in test stand
  17. People measuring rocket’s vibrational modes by pushing it – same happened for Ares –
  18. Stage built vertically but engines inserted horizontally –
  19. First stage of Apollo 16 caught fire during tests. Engineers forced to look at the failed parts.
  20. S-II second stage by NAA in California. Not kerosene but hydrogen. One tank with one bulkhead within
  21. Testing at same Mississippi facility still used
  22. Story of mistaken loading to explosion due to incorrect procedures
  23. First stage o2 not insulated but second h2 had to be. Several attempts up to Apollo 13.
  24. Third stage S-IV B similar to second stage but one engine.
  25. Tanks hemispherical in 3rd ellipsoidal in 1st and 2nd
  26. 2nd stage external insulation strong metal inside. 3rd stage insulation inside by tiles that didn’t fall off.
  27. Picture of Skylab being built out of 3rd stage
  28. Explosion in Jan 1967 of S-IVB-503 3rd stage one week before Apollo 1.- problem with Helium tanks
  29. Problem with welding of He tanks.
  30. Pictures comparing sites in 1967 and 2006 –
  31. F-1 rocket engines – tested at Edwards
  32. J-2 tested near Hollywood
  33. Overview of Saturn V flights. Second flight not so well (Apollo 6) with 2 lost engines then Apollo 8
  34. Apollo 8 – a major structural failuree in California a day earlier but launched anyway
  35. Pictures of test firings of Apollo 11. Lightning striking Apollo 12. Apollo 17 3rd stage never test fired.
  36. How did they make it so perfect? Leadership, mindset. Von Braun and other German managers
  37. Many things worked by dodging bullets
  38. Personally I would not be surprised the programme was stopped before a major accident would kill it and spaceflight

The lecture followed the publication of “Saturn” by Alan Lawrie with Robert Godwin.

Surefire way to avoid all risks

leave a comment »

According to the World Health Organization, mobile (cell) phones “may cause cancer”. However, there’s no established link. Still, it could be a possibility. It could also not be.

Therefore a bunch of experts have decided to warn the public with the non-news. Maybe that’s the “ethical” thing to do.

But if that’s true, then we should warn the public about a far more certain risk. You see, it can be easily established that the one thing in common among people that die, is that they were alive in the first place.

Armed with this incredible revelation, the WHO experts will soon recommend us all not to be born at all.

Palin For President

leave a comment »

There are two things going for Sarah Palin. Apart from a following among middle-aged men that is (doesn’t look like the typical grandma, does she).

One, “Sarah Palin” has been portrayed such a mindless idiot, she’ll earn points just by reading the time right, out of a talking clock. There is a great advantage in lowering expectations.

Two, she’ll have a very easy time convincing people that it’s the Press that paints her in a negative light. So during a campaign, if there’ll be a campaign, she will describe all of her faux-pas and gaffes as “don’t listen to that, it’s just the evil Press”. Even the real faux-pas and gaffes, that is.

IOW on all fronts she will be able to say or do anything without fear of losing score with anybody in the electorate (unless she’s photographed kicking a puppy or slapping her mom). Every additional day will be a day with more supporters.

It’s developing in the classical shoo-in…
