Beast tribes and general advice for "ft" gatherer? :o

A Few Tips to Get You Started

I see you have Fisher and WVR at level 50 so I know you aren't exactly starting from scratch but I hope this is useful to you.

Crafting
First, I'd suggest thinking about your long-term goals: Do you want to be an omni-crafter/gatherer or are you just interested in levelling a couple of classes so you can repair your own gear and make a few things?
If you're not sure, the best advice I can give you is to level all the crafting classes to 15. This will give you cross-class abilities that will be a great help even if you decide only to level a single class from then on.
The vendor in each Crafting Guild sells most of the materials you'll need for those early crafts. Complete the log for a nice chunk of XP and if you have a Friendship Circlet you can wear it to further boost XP (works for gatherers, too).

If you decide to go the omni-craft route, level all your crafters together. You will get very useful cross-class skills by levelling all to 50.

Gathering
It pays to level your gatherers slightly ahead of your crafters, especially if you omni-craft (that's why I suggested thinking about your crafting goals first). I had no problem levelling my gatherers just by getting materials to craft. I didn't need leves at all.
If you are only levelling a few crafting classes you may find you need leves to level.

Advantages of omni-crafting
You will be able to make all your own Gathering and Crafting gear in HQ (you won't get HQ quest rewards for gathering or crafting class-quests). You will also be able to make your own food, potions etc.
This is the cheapest way of doing things. It certainly involves a lot of effort but if you enjoy it, it's well worth it.


Odd Classes
If you are only going to level single classes here's 2 to avoid: Culinarian and Fisher

Culinarian is fairly easy to level but it is excluded from some very useful abilities. eg. You cannot learn how to affix materia as a Culinarian.
You will also get less scrips for your crafts when you make Collectables for Rowena (needed to buy master crafting books at higher level, materials and gear).
However, if all you want to do is craft food for your battle class it's obviously the one to go for (Botanist is a good complimentary gatherer).

Fishing is basically Gathering Savage. It is easy enough to level but it is peculiar and has it's own set of rules. You can very easily end up with your bag full of different baits and only a very small proportion of fish you catch are actually useful. So it's of little use for making gil, although some end-game fish can be profitable. Going after specific fish can be very frustrating (you'll catch everything else).
However, it's fun to do as a relaxing side-activity and there is a certain satisfaction in filling up the fishing log if you are the collector/completionist type. There is also a very challenging series of quests at level 50.
Spearfishing which was introduced in Stormblood is a lot of fun (easier to catch what you want too, in my opinion).
Level it if you enjoy it, but don't expect to make a lot of gil.


Retainers
I would get one battle (your main class) and one gathering retainer. The battle retainer will be able to bring back animal products like skins, fleece, horn. For gathering, I'd choose Botanist or Miner.
Level them up and keep them geared. They will be invaluable at higher levels.

Gear
For both crafting and gathering keep your gear up to date in the same way you would your battle classes. Tools and Chest are a priority.
Trying to craft or gather with low-level gear is frustrating and difficult (I had a few friends who wanted to get into crafting who just couldn't get their heads around this). Treat gathering and crafting the same as your battle-class, upgrade as often as you can and go for HQ. It will make your life so much easier.

Beast Tribes
There are no beast-tribes for gatherers unfortunately. Ixali are for ARR Crafting (some gathering involved though for all classes) and then you have Moogles in HW (Moogle quests don't involve gathering but are very quick and easy compared to Ixali).


Gathering after level 50
HW Gathering is quite complicated. There are a lot of timed nodes with some items only being useful as Collectables (Rowena) or for Zhloe (Custom Deliveries in Idyllshire). You also have Aetherial Reduction from Ephemeral Nodes and Favors (don't bother with Favors, you shouldn't need them).
You will be using different rotations for Collectables, Aetherial reduction and gathering materials.
There's not much point in overwhelming you with information, so I've taken the lazy route and linked the guide that got me through it below.

Collectables
You can start these in Mor Dhona but apart from doing the quest to unlock them, I wouldn't bother with them until you get to HW. The XP is positively stingy.
However, they are definitely worth doing once you can get scrips. If you don't want to level all your crafters, these will be your cheapest source of gear. Crafted is slightly better when melded but the scrip gear is almost as good and can be uprgraded.


I seem to have written a lot about crafting. For me, it's hard to separate Crafting from Gathering as they just seem to go together. Anyway, I hope this was useful. I'm sure I haven't covered everything.


Here are the guides I used to level my crafters and gatherers:

Gathering is very simple in ARR, no guide needed. However, from level 50 onwards, you'll probably need a little help. This should help you make the transition:
