Question about lv 50 Gathering Retainer

[Alphadeus]

Nice info here.

What about high level fishing?
Someone can confirm if and how many "rare" fish a retainer can bring back?
Like Silver Shark, Fullmoon Sardine, Razor Clam,..?

I posted this in another thread:
46-50 is just Northern Pike (46) & Cloud Cutter (48)
41-45 is Silver Shark (41), Raincaller (43), Blacklip Oyster (44)
36-40 is Whitelip Oyster (36), Velodyna Carp (38), Red Coral (40)
31-35 is Indigo Herring (31), Ash Tuna (32), Fullmoon Sardine (34)

As far as quantities: 3 Silver sharks, 7 Razor Clams, 7 Fullmoon Sardines. If you want the rest, let me know ^^ I think I'm limited in how many characters I can put in one post.
