Excalibur Tuna Fishing Boat Tour – Newport Oregon – YouTube Travel
Posted by admin on Jan 21, 2012
Beautiful Newport harbor and a tour of the fishing boat Excalibur, wow.
Imagine sailing on a 90 ft aluminum boat to Hawaii then Tahiti, Fiji, around Asia on the way to Japan and back to North America chasing fish.
25,000 gallon fuel capacity is not enough to make the round trip…a 1 dollar difference per gallon of fuel if refueling fully is $25,000 – the boats on this circuit do not refuel in Canada.

Long term radiation effects, in Tuna?
With many of the long term effects from the Japanese Fukushima Daiichi nuclear power plant disaster still ahead of us, a serious consideration should be made regarding the food chain and the possible radioactive contamination thereof. In this example, let’s look at Tuna fish. Is it safer to buy canned tuna now, before possible contamination into its food chain?
They spawn in the Western Pacific between Okinawa and the Philippines and the Sea of Japan and they migrate over 6,000 nautical miles to the Eastern Pacific, eventually returning back to their birth waters to spawn again.
What do Tuna eat?
Tuna mostly eat small fish ranging from 1.5 inches up to 6 inches. Tuna will also eat squid, and very occasionally will consume crustaceans.
The small fish that tuna will eat include skipjack herring, flying fish, lancetfish, puffer fish, triggerfish and rabbitfish.
60% fish
20% squid
15% crustaceans
If tuna eat smaller fish like Herring, then what do the Herring eat?
Herring (a.k.a. trash fish) eat mostly plankton, as well as algae and some kelp.
If tuna eat squid, then what do squid eat?
Squids are carnivorous. The smaller species of squid mostly eat shrimp, and other small fish.
How could radiation enter the fish food-chain?
So now that we have an idea of what type of tuna is caught off Japan, and what it is that the tuna eat, lets hypothesize how radioactive particles could be ingested into this food chain.
We know that they have been dumping tremendous amounts of radioactive water into the Pacific ocean. This is the water that they have been spraying onto the reactors, fuel rods, and fuel pools while trying to keep them from entirely melting down. The problem is, there has been partial meltdown and the radiation is traveling with the water runoff, which is currently being dumped into the ocean (some water is being diverted into storage tanks).
Of much higher concern is Cesium-137, which has a half-life of 30 years (considered gone after 300 years). Of even higher concern is Plutonium-239 which has an unimaginable half-life of 24,000 years (considered gone after 240,000 years).
The radiation in the seawater is surely getting diluted, however fish are swimming in the water, and the diluted particles of Cesium and Plutonium will remain somewhere in the oceans for 300 to 240,000 years. Do you know how fish stay alive? They constantly are passing water through their mouths into their gills — never ending.
Not only do little fish stay alive this way, but also big fish. So, not only will big fish get their own radiation through water injection through their gills, etc… but the big fish also eat the small fish. Effectively then, they are getting More radiation.
The big fish are then caught for processing, distribution and consumption by humans.
Where does the ‘canned’ tuna come from?
About 68 percent are caught from the Pacific Ocean, 22 percent from the Indian Ocean, and the remaining 10 percent from the Atlantic Ocean and the Mediterranean Sea
When you open a can of tuna, you don’t know where the actual tuna was caught.
Odds are of course, that the tuna in that particular can may not have been caught off the shore of Japan — it could have been caught in any other number of places in the Pacific. Lots of these tuna migrate their way to the west coast U.S., but it takes awhile — years in some cases.
No doubt the food supply chain will be examined further as time goes on, particularly if the situation continues to worsen at the Fukushima nuclear plant (It’s already a level-7, the highest on the nuke disaster scale). True results may not be measured for many years to come while looking back at cancer rates.
No amount of radiation ingestion is ‘OK’ though. A single Cesium-137 particle stuck in your body could start the chain reaction that leads to cancer.

Kiribati — We chased it for 5 days, but as dawn broke over the Pacific this morning we finally confronted the biggest tuna fishing vessel in the world. The Spanish-owned and flagged tuna purse seiner “Albatun Tres” is known as a ’super, super seiner’ and can net 3,000 tonnes of tuna in a single fishing trip. This is almost double the entire annual catch of some Pacific island countries.

HD: Tuna Fishing – South Pacific – BBC Two
Posted by admin on Apr 5, 2010
Episode 6 Fragile Paradise: The South Pacific is still relatively healthy and teeming with fish, but it is a fragile paradise. International fishing fleets are taking a serious toll on the sharks, albatross and tuna, and there are other insidious threats to these bountiful seas. This episode looks at what is being done to preserve the ocean and its wildlife.
