the video would be quite useful for those who dun like to read.

Ahhh fish head curry. That would be the snapper.

But not only the origin of fish head curry (Malaysia/Singapore) are controversial, the name of different snapper in English, Malay, Hokkien (northern Hokkien e.g. Penang, southern Hokkien e.g. Johor, Singapore Hokkien, East Malaysia Hokkien) are a mess too. Based on my limited understanding, red snapper is referred by the Hokkien as Ang Hu ? or Ang Kueh/Kuay ? but in English speaking community, red snapper is from tropical water around central & south America (atlantic/pacific?) which is around the same area as where Goliath Grouper are from.

I read somewhere before that there are 1 types of snapper (Crimson Snapper) that Australian (consider close to us, Malaysia) ang moh would die die say it is red snapper when debate about red snapper with ang moh from other country especially USA (cause the other 2 major ang moh country is Canada & UK which have cold water while snapper are mainly tropical fish).

There is also another type of snapper that would be refers as red snapper occasionally by Australian. So, I will include informations about those 2 snapper and a few snapper that I know about.

As my personal conclusion, Red snapper / Ang Hu / Ang Kueh or Kuay / Ikan Merah is a common name or umbrella term (most probably true in Malaysia). It refers to all red coloured snapper, in a same way when we say dog while ang sai, ang goi, ang zhor & etc would be the same as when we say a husky, corgi and etc.

P.S. I do not own any of the photo as below.

And before that maybe I should includes an external anatomy of a fish as the descriptions of a fish would always talk about body part like dorsal fin, pectoral fin, pelvic fin, anal fin, lateral line & etc.



* Btw, all tropical snapper have canine teeth to grab hold of its prey.

Is this why the guy say it is a secret?

Maybe his project is in a new location after the one mention in the news failed or proven to be fake.

Not my project and that project is a joint between gov and private.

My baby is 2months old. My wife eat fish almost everyday when she is pregnant. She only eat threadfin fish 午鱼, sardines, promfret, cod and salmon only. Cod and salmon only consume every 10days to 14days once. And she drink avocado juice thrice a week and take neurogain pb 300 everyday.

Skip salmon and cod

Replace with Jade Perch local farm.

Which type of threadfin fish 午鱼?
After seeing what xxhenry89xx wrote, I better stick to Ikan Senangin / Fourfinger Threadfin / Peh Ngor .

sardines, promfret, cod and salmon, I agreed

cod? hmmm

I think i better add some seaweed too for my wife & kids. and use anchovies, grind it into powder to make soup or stock for cooking.

Nice info.

EDIT
Phew.. quite a good reading material.
TS, Leo.Lee and xxhenry89xx, I know that this thread have been a while but I would take my chance in asking how about other kind of seafood like lala, siham, hoi sam?
I mean at least their English name > Mandarin name > Malay name?

I am lazy to open a new thread with no reply or with nonsense reply. I might as well just post it here where it seem there is quite a few seafood experts here.

Table of common edible fish in Malaysia (Reddit)

Just sharing this journal for who like to read. i'm not browse all 10 pages so i apologize if already bening shared.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4334092/

Total mercury levels in marine fish sampled from the fish landing ports and the wholesale markets in Peninsular Malaysia are summarized in Table 3. Mercury levels of 46 marine fish species ranged from 0.055 to 2.537 mg/kg of dry weight. Significant variations of mercury levels exist in different species (χKW2 = 103.581; p < 0.001).

Among pelagic fish, the median for mercury levels was higher (>0.5 mg/kg) in scad (Selar boops) and bonito (Sarda orientalis). While for the demersal fish, the highest mercury levels were shown in John’s snapper (Lutjanus ruselli), mangrove red snapper (Lutjanus argentimaculatus), and doublewhip threadfin bream (Nemipterus nematophorus). Mercury levels were significantly higher in higher tropic level fish (χKW2 = 7.787; p < 0.02).
