Sorry I'm not sure of a guide, there may be one, but I never used one. Personally I just used to use YG and look for sea sand/river sand.
River SandSea SandJust click on the recipe tab, and it will show all the recipies known that can make these items. The ones that state the level as 0 are technically not in the game. You can get the recipe from leve quest reward, but the fish aren't in the game, so ignore them ^^;
IIRC after you are done with Y. Salmon you pretty much are finished making the sands, and it is best to move onto other recipies such as apple juice, tomato pie, stuffed cabbage etc (when your level is high enough). Also, once you are level 40+ mass doing crafting leves (the ones where the client is in the city, preferrably Limsa) is a extremely good way to grind to level 50 fast.
As for Y.salmon location, you can get them at G2, but I always found the best place to get them was Camp Tranquil lake (G3 waters, so L15+).
As a final note, fishing can technically take you all the way to 50, but it can be very slow. I believe you do Yugr'am salmon as high as possible, then do Mugwort Carp (mugwort can be purchased form npc I believe). After that you move onto Stuffed cabbage and grind that all the way to L50. I don't recommend this way though, instead just do this until about R42 cul (stuffed cabbage/tomato pie) and do leves the rest of the way.
Happy Cooking!
