That looks like a Barramundi (similar to our snook).
Are you going to HK for a visit and then returning to the US, or are you relocating for a job?
The reason I ask is because if you’re just visiting for a short time you may want to buy an outfit that you can use in HK, but is also primarily suited for the SW fishing you may do here in the US. If so, tell us where you live and what you’ll be fishing for, we can make some suggestions for gear you’ll get a lot of use out of.
Because of the limited FF opportunities over there it would be tough to put together an outfit, so I’d suggest buying something you’ll get the most use of in the future and making do with it in HK.
Not much fly fishing goes on in HK as you said, but there are a few guys that are into it. Your best bet for finding out more info on fishing HK would be to post on this sportfishing Asia forum, which has a big HK section. Here’s a link:
Sport Fishing Asia Forums
As far as books,
Fly Fishing in Saltwater by Lefty Kreh- probably the best all around book for SW FF
If you’re in the NE, these are very good:
Fly Rodding the Coast Ed Mitchell
Inshore Fly Fishing Lou Tabory
There are also great but more specialized books on fishing for different species like tarpon, bonefish, big game etc etc.
As far as tackle that will vary depending on the kind of fishing you’ll be doing, the most down the road but as says a good choice would be an 8 or 9 weight outfit for general inshore and a 9 or 10 for light tackle offshore. If I had to choose one rig for all around SW it would be a 9 weight, but a more versatile arsenal would be an 8 and a 10
Reel to match rod, with SW corrosion proof finish, smooth dual drag, backing capacity with fly line 200 yds of 20lb Dacron (for 8-9 weights) or 200 yds 30lb for 10 weight. Preferably CNC (machined rather than cast), with Type 3 Anodizing with cork drag IMHO but some may disagree.
Line: a weight forward floater will probably be the most useful from shore. If you wanted to add a sinking line on an extra spool, I’d probably add an Intermediate, if you will be doing most from shore. If you were doing your FF from a boat, I’d have either a floater or Intermediate and a full sink, fast sinking line. If you were planning to do both shore and boat, I’d go with a floater and a full sink.
Leader: These can be much simpler in SW. A good set up for a 8 or 9 weight inshore set up with floating line is a 7 foot leader 3 ‘ of 30lb to 2’ of 20lb to 2’ of 15lb. I just use Ande. Mono. You can tie larger flies (2, 1, 1/0, 2/0 and 3/0) directly to this, or if you’re going for smaller fish with smaller flies (6-2) add 3-5’ of 8-12lb mono or an overall length of 9-11’. A leader for a sinker or intermediate fly line can be even simpler- a straight shot of 20lb test mono 4-6’ long should be fine.
Shock tippet- you’ll need this if you run into for toothy fish. A short 6-12” length of 60lb test for use with larger flies for most fish (snook type stuff), and a pack of knot-able wire like Tyger Wire for sharks, barracuda etc.
Flies- just a general selection of basic stuff for inshore:
Deceivers 1/0 or 2/0,
Clousers 2 and 1/0,
Bendbacks size 1 for weedy shallow areas, and
Small bonefish type stuff for smaller fish you might run into- Gotcha’s 6, 4 and/or shrimpy crabby Borski patterns 4, 2,
Del Brown (merkin) Crab flies size 2
If you were to do some off shore stuff from a boat, add a few heavily weighted flies like :
Half and Halfs 3/0 for dredging deep channels oil rigs etc, and
Poppers or Crease Flies 2/0 in case you have stuff like Amberjacks or Mahi on top.
This is not a specific pattern list for HK, but just a selection of basic generic SW patterns that will cover a lot of different bases pretty much anywhere.
Hope this helps a bit. Tell us where you are and the types of fishing you plan to do beyond HK and a rough budget. Maybe we can suggest some specific stuff for you to consider that you'll get the most use out of after the trip too.
