Can anyone ID this giant grouper ?

Guys,

I am just learning how to use my capture card with quite advance software....and I can't use it....ha ha ha. So I ended up using Windows Movie Maker and pause the DV Camcorder button and record this fish. I don't know how to capture in higher resolution, sorry. The loss of colour at depth maybe misleading.

Anyone knows what kind of grouper this is ? Taken at 100 feet, low light. Defintely not a Jew fish, it is almost all black. Indian Ocean location.

Our first sighting of such a big grouper. I wish I can see Jew fish like you guys are seeing in the US now.


Thanks
IYA

Could it be a potato cod? The Indo-Pacific version of our jewfish.

Surface ID ? How ? We did not shoot the fish. It was our first sighting of a grouper this big and in this tuna alley. It is kind of slow and can be approached within 6 feet of us. I don't have the heart to shoot it and most importantly I don't know if is delicous or not. I know one local brown grouper that can grow big ( 50# ) and taste like rubber.... and smell bad too. I am afraid if I shoot it and it taste worse than rubber...what a waste. I seen only one so far, if I seen a few more same size, maybe I will land one someday. I kind of feel bad if their population is low and I whack them, even though no law protects them.

I tried looking at all website with grouper ID and the closest one I think is the US black grouper but I am unable to locate any decent U/W looking photo.

The only BIG grouper I know being delicous is Potato Cod ( Aussie name ). It is protected in Australia but not in my place. They are not common here, though.

I seen and shot a Potato Cod, no, this is not a potato cod. Potato Cod is white with black stripe and dots, very obvious.

Thanks boys but I am still confused. It is the color of the fish that I can't tell at that depth. I am poor with big grouper, small one I can tell by the sillhoutte. This is the best shot I have of it.

That long low front dorsal and the other rounded fins almost certainly puts it in the Jewfish category. Maybe it just had rare color or markings but the sillouette surley screams POTATO COD!

Giant grouper (Epinephelus lanceolatus), a close relative to the Atlantic jewfish.

http://www.fishbase.org/Summary/Spec...me=lanceolatus

Here are some pics:

http://www.fishbase.org/Photos/Thumb...ry.cfm?ID=6468

At that depth and distance from the fish, the spots along the fin tips will be hard to see unless you hit it with a dive light.

Here is a neat feature, though it does not really work accurately:

scroll down the depth range on the right side of the screen to see a dramatization of coloration at depth.

NOTE: large individuals may be ciguatoxic.

Cool

Gotta love de' fishbase website .Esp.the google pics linx.We used it to settle the Big Mangrove/Small Cubera arguement a few times.Iya,try soaking fillets in milk and cutting them as thin as possible when cooking to help cook evenly.This helps keep big fish tender.That is ,if you get tired of Tuna

Thanks Mike, Wet and 100,

That link is cool, I did not know the grouper can look like tiger stripes.

I just called one of the local captain of that area and told him about the grouper. He said there was once a 600# taken by a traditional fisherman, it was half stoned from being cynide.
Some SOB traditional fisherman likes to use cynide. They will fll the stomach cavity of a small bait fishes with cynide and throw those fishes into the water. Eventually a few big fishes will surface gasping for air ( that's the effect of cynide fishing ).

Possibly there are two species which can go this big. I think the easiest will be to go to the fish market, they have one big one there.

Soaked in milk, that is new...thanks.

WET, Potato Cod definitely not. I just remembered that my friend of that trip saw two giant groupers on the last dive. The one I video and a Potato Cod. That means the Potato Cod still shows its pattern even at that depth. Does this mean the groupe I video is almost all black or at least very dark brown ??

Here is a typical Potato Cod :

100, I think me will not get tired of tuna for a very long time...he he he. Here is how they look like from the top. They are about at 150 feet. About 30-40# or so.

Nice tuna pic. I just don't know of any other fish than a jewfish with a dorsal like that.
