xxhenry89xx, did you do some update? I remember there is no mackerel in your list when i read it.
Btw, I heard that there are people (especially Chinese) that call Narrow-barred Spanish Mackerel as Batang Yu/Batang fish.

Don't tell me that this is the Goliath Grouper that you mention in previous few post?

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

Saltwater fish

Dragon Tiger Grouper
Also known as  : Hybrid Grouper / Sabah Grouper
Scientific name  : Epinephelus Fuscoguttatus x Epinephelus Lanceolatus
Mandarin name  : 石斑魚 (Shí bān yú), 龙虎班 (Lóng hǔ bān)
Cantonese name : Long Fu Paan
Malay name  : Kerapu Hibrid, Kerapu Kacukan
Details:
• A new type of grouper results from cross-breeding.
• There are a lot of hybrid grouper in the current market but the first hybrid grouper is cross-bred via researches from Universiti Malaysia Sabah (UMS), Malaysia, in collaboration among researchers of the Borneo Marine Research Institute of UMS, the Fisheries Development Authority of Malaysia (LKIM) and Kinki University of Japan, represented by Prof. Dr Shigeharu Senoo of UMS.
• This grouper was produced by fertilising the eggs of the tiger grouper (Brown Marbled Grouper or Lao Hu Ban in Mandarin) with the sperm of the giant grouper (Long Dan in Mandarin – literally mean Dragon Grouper) through the in-vitro fertilisation (IVF) technique; hence earning its name of Dragon Tiger Grouper derives from its Chinese name.

Most Marine fish are farmed as well.
Hybrid grouper is a cross between tiger and Goliath and hence is what you are eating in most of the restaurants. But they still coin it as sek pan, even though it's already crossed hybrid between 2 species.
Ok?

Fren, you really think we have goliath grouper in the menu ? It is a 400kg fish.

This is a Goliath Grouper.Look at the size of this monster. It is even harder to pull up than a shark, just less stamina but massive resistance. It is a critically endangered species.

I think the fish that most chinese call "Loong Dan" is Giant Grouper. Goliath grouper and giant grouper is not the same.

Yes we do. Our Goliath grouper, Taiwan Goliath, Indonesia Goliath and Thailand Goliath is diff species but all under this category.

Don't tell me that this is the Goliath Grouper that you mention in previous few post?

Because the guy mati-mati say Dragon Tiger Grouper is mixed between Tiger Grouper & Goliath Grouper (actually with Giant Grouper or Loong Dan). So, I was wondering...

No. I already said b4 that Goliath and beluga are confidential information which i am not allowed to reveal.

Not to worry. In about 2 years you will get to taste the new long fu pan commercially.. Which is hybrid #3. Goliath cross breed with tiger . In Taiwan, this is available. In Msia..... Need some time more. Taiwan is the only country to successfully mass breed Goliath for now. We are close by together with Indonesia.

Goliath growth speedy, but the sperm is not so easy to obtain. So for now, if u want to eat the latest hybrid long fu pan, it's Taiwan. Msia got but is import. Not locally produced commercially yet.

Ahhh.. I think i know what you mean now.

1. You most probably not referring to the original Long Fu Pan when you said it is a hybrid from Tiger + Goliath.

2. Since goliath are not from Asia, Chinese (normal people) especially might not have name for Goliath Grouper but it is close enough to Giant Grouper. So, you call the Goliath as Long Dan as well.

3. I see. There is some kind of new breeding program / research using goliath grouper to make use of its fast growth gene.

4. I see. I do heard that Taiwan are leading ahead in farming grouper.
An article from WWF (World Wildlife Fund/World Wide Fund for Nature) state:
"Responsible grouper farming
While giant grouper in Taiwan is now based almost entirely on full-cycle culture, the farming of this species in other countries (i.e., Indonesia and Malaysia) still relies mostly on wild-caught seed for grow-out. With its technological superiority and proximity to markets in Hong Kong and China, Taiwan has dominated the supply of this species for many years with little scrutiny over sustainability and quality issues."

The rest in:
WWF's article about Taiwan's grouper farming

Not really about goliath grouper but about grouper farming in Taiwan.


Extra:

The original is correct. Is giant grouper male with tiger female. That is original long Fu pan. But that was years ago. Now is Goliath male with tiger female. I know a few famous Chinese restaurant chain which started importing their own from Taiwan. Kajang fei chui is one where u can find the newest hybrid grouper. Goliath with tiger cross breed.

U won't see size diff cause table size is still within 1kg-3kg. But the growth rate and immune system improvements.....fuhhh best wei.

We do have Goliath in our Waters Just that it is very rare and we just follow since there is already a scientific name given. No point to call your same species another name when a name has already been present. The only issue with this entire procedure lies in the Goliath sperm.

I have to admit, Taiwan had great tech and techniques, Thailand and Indonesia is actually not that far off. We.....Abit slacking la usual la.

Is now 2018. Even proton saga has new design. Nobody calls them proton saga 2. It's still proton saga. Same as long Fu pan.

I see. I think i understand what you are trying to say now, more or less.

"U won't see size diff cause table size", yup I understand. cause it is farmed. Most farmed fish would be considered as marketable / can eat liao / big enough around 1 - 2 kg.
The reason for using a speedy growth gene is to cut cost. Example (the duration is fake, as example only): Something like normal grouper maybe take 1 year to reach 1-2kg size, then long fu pan take 6 months because of Giant grouper growth gene, then the one with Goliath gene only take 3 months = cut cost like feeding lesser, production higher.

kajang one? you mean this one?

no choice, in this industry what they say we have to follow. if they say dont have, then dont have. we aren't gonna be the ones arguing with the board, otherwise we jeopardize our business.

your zoo plankton only applicable to very few types of marine species. siakap , jenahak and those ikan merah tahan lasak types. kerapu, tongkol and others cannot. only use pure cultivated rotifer and artemia. even copipot also we leave out. i know someone who owns a mahi-mahi farm here in malaysia. doing pretty well, and he is only purely on 0.03 micron artemia.

you are partially right but still uninformed. the trend is already moving away from conventional farming of grow-out in sangkar. those are the ones baru nak masuk join in the crowd or yang takde modal. every medium sized player has already moved to partial RAS. low discharge, sludge kek, low maintanence, high efficiency. works well especially for those located at perairan selat melaka. those who export gotta comply with LKIM and their respective jabatan perikanan (moa). since i'm qualified, i was put to certify a few plants and premises and all i see are RAS and CRAS systems. no foreign objects, no foreign modules, no foreign particles, no foreign matter.

the only reason why there was a discussion between us and MPOB is the worries of the discharge flow, industrial waste and the pesticide/ferti that seeps into the soil and slushed away by rainfall into the sea. palm oil plantation and aquafarming dont really work hand in hand. we're more like i hate u, u hate me kind of thing.

but do rest assure, majority are moving or have moved to RAS. its the only way to obtain a higher yield and control diseases and water quality. the protein skimmer, degasser, inducer, ozone and biomedia + UV is enough. conductivity is monitored constantly so i can assure u, there are little or next to no elements of metal. its pretty much a stripped up clean water pretty close to De-ionised water system (cept we retain salinity)

xxhenry89xx, did you do some update? I remember there is no mackerel in your list when i read it.
Btw, I heard that there are people (especially Chinese) that call Narrow-barred Spanish Mackerel as Batang Yu/Batang fish.

Yes      I did update it for TS.
Yes about Batang Fish. I did noticed that but i think it is mostly use by Singaporean (if I am not mistaken.)
I didn't write it down cause for a banana like me it sound really wrong.
Imagine a conversation between 2 banana as below:
A: Hey, do you wan to eat my Batang fish. I just baked/cooked it.
B: 

P.S it sound like asking ppl to do BJ (if you know what i meant.  ) for you.

Pretty much that. U cut the time it takes to grow, u cut the expenses of farming to obtain a quicker yield. Feed is a diff story so I won't touch on that portion. U won't be feeding any lesser. In fact u actually feed more.

I have 2 young kids and my wife are pregnant with another one. My wife have been frequently advise to eat more fish especially those with high Omega 3 content as Omega 3 are good for brain development. It also have the same benefits for young child and also benefit adult in one way or another.

However, I realize that there is also the concern of mercury content in fish especially popular high Omega 3 fish such as Tuna, Salmon and etc. To deal with that, I am thinking of eating plant based Omega 3 & local freshwater fish with lower Omega 3 content (not sure how low) but recently I heard that freshwater fish actually have higher mercury content that can affect brain development. I am confuse  . Do you guys have any info about this?

Other than that, I also wanted to show my kids the photo of those fish before it is cooked & served on a plate as I noticed many youngster today don't even know what kind of fish that they're eating. (Including myself, I only know few but not really sure how to differentiate it). I don't want my kids to be like those kids in developed country like USA & etc that don't even realize the foods that they eat especially meat are living being that have head, feet, name and etc before being served as food.

And being a Chinese and living in Malaysia, I also want to know and tell my kids the name of those fish in Chinese, Malay and etc. Hope you guys have some info about this.

Mahi farm in Msia for >6 years jor. The one even I also impressed is the beluga farm.....in Msia. This when I first visit also I shit brix. No trout or spot farm yet in Msia though.
