Tuna and Parasites
Got an SBT today, filleted it and was disappointed to find its flesh riddled with parasites. No sashimi for me.
After doing a search on here I emailed fisheries for a bit more information. See below the article they directed me to.
Parasites.
Myxozoans are commonly found parasites that infect both marine and freshwater fishes. They are found principally in the muscle, the brain and the gall bladder of their host fishes.
Fish filet with obvious white cysts, in this case a sign of infection with the parasite Kudoa.
Some species of myxozoans can cause death in fish. Non-lethal effects can include the production of small but obvious white cysts in the muscle that make fillets unsightly, unappetising and therefore unmarketable. Some species in the genus Kudoa produce enzymes after their host dies that cause muscle breakdown, making fillets soft and watery. This is known as post mortem muscle liquefaction. Stained histological section of fish muscle showing numerous Kudoa parasites.
These types of myxozoan infections pose significant challenges in commercial fisheries and are also of concern for aquaculture and Australia's biosecurity.

Cray bait
Sadly it looks like the fish is only good for cray bait.
Still at least it can be used for something and it is not going to be just dumped in a bin.

Bummer about the meat...
...but little bait caster plus pink skirt plus SBT equals tremendous fun! Is that a 400b Calcutta? My personal go-to tuna troller!

If cooked do they pose a risk to people? Coral trout and rankin cod etc almost always have some worms in the flesh but apparently are OK to eat when cooked

had a bad run in Exmouth
had a bad run in Exmouth (august) with myoxzoans. Out of 5 YFT, 3 had parasites, these fish were caught on different days too. Out of all the YFT ive got up in Exxy never had an issue with any of them with parasites until this year.

Cooked I believe it is
Cooked I believe it is absolutely fine, I usually feed it to friends cooked and just dont tell them. Raw could be different depending on the parasite...
Interesting article (short read) here. Given the amount of raw mackeral I have eaten I would say the mackeral parasite does not affect us. Especially if like the article says they all have the parasite. Love sashimi mackeral, certainly will not stop eating them either!
