Chech out these links that refer to how safe it is to eat Dorado or Marlin. Very interesting for sure. Due to high levels of Mercury in Marlin it is a very bad idea indeed to be eating them. First link talks about mercury next one is about dorado and the last one is on mercury levels in Marlin.

I hope These Folks Know more about Mercury than they do about fish...The all tackle world Record Stripe Marlin is 494 pounds and was 11 feet Long. Here is what they say about Stripe Marlin !

More About Striped marlin

Like all the marlins, the striped marlin is distinguished by its characteristic spiked horn and pointed fins. This solitary predator is found in the subtropical waters of the world's oceans. It can grow to over 13 feet (4.2 meters) in length and weigh 900 pounds

Also They Indicate Dorado Grow to over 6 feet long,,Again the Pending world record is Much shorter than that...I wonder if they exaggerate all there Facts ????????

I say Release for the Future, not Mercury Levels

I guess this means I need to stop ordering the Fillet-O-Fish and step up to the Big Mac :D.

If you look at the main studies that these warning are based off of the Methyl mercury levels vary greatly and they have even found high concentrations in fresh water fish such as trout and bass. The FDA warns pregnant and breast feeding women as well as young children to limit two portions of fish a week. If my diet was only fish, 3 meals a day then I might be worried. The benefits of eating alot of fish far outweigh the risks when it comes to eating fish.

I'm curious as to why the studies don't reflect the statistics of indigineous people who eat nothing but fish every day. You would think these people would be very unhealthy but that isn't the case.

 

I release fish so that they get bigger or can feed a much larger fish for me to catch :)

Well I can tell you Steve that I was told the same thing about Mercury by the Bill fish fund when I was in Cabo a few months ago interviewing Ellen Peel, the current president and Russ Nelson thier resident scientist. Google mecury and marlin if you doubt the web site link I posted and you will find plenty more sites with virtually the same info.

Did you know that America is actually the number one importer of Marlin world wide and I bet if you thought about it for a while you might be able to figure out which country is supplying a fair amount of that Marlin to the gringos.

does it really matter what your motivation is for releasing fish?  the marlin appreciates it either way.  seems to me just one more good reason to encourage people to do the right thing anyway....

Marlin? Yes. So are swordfish, sharks, and large grouper. Virtually ALL top of the food chain predators are. Mercury is cumulative in most fish -- the older and larger the fish, the higher level of mercury it will have.

Dorado, however, are fairly short-lived fish, especially when compared to marlin. The amount of mercury accumulation is nowhere near what a big marlin or shark accumulates in its life. Dorado are considered very low in mercury overall and are on most "safe" lists. 

I wrote a complete training program on this subject for these folks, Sustainable Fisheries.org. They have lots of info on mercury levels (click the link for a downloadable card), as well as a tagging system used in markets to label not only mercury hazard, but sustainability of the fishery itself. Very good folks and very good information! They work from grants and are trying to make a difference by educating the public on what's "good" seafood vs. what's "bad" seafood.
