Fishing Achievements
You have to use only one hit to bring fish to your boat. The easiest way is to get Dragon Slash and cast is while catching Herring (first fish).
Catch 25 fishes before selling or gaving them for quest.
You have to lose to the herring. Right now the only way that I know is to use Ring of Dormor that slowly drains your life. Wait till it hit 0 hp and you will get the achievement.
You need to use Parry(Q) while one of Bosses uses special attack. The easiest one for that is boss in Forest when he want to attack you with sword. All you need to do is time it right.
Some fishes apply status effect to you when you ry to catch them. Just use Talon Mushroom to remove this effect. The first fish that can apply status effect is Magic Carp with Stun.
During fight with any fish, use potion, food and spell. Just cast any spell, replenish stamina with Stamina Potion and use Talon Mushroom or Peace Bloom.
Collection Achievements
Catch every fish and visit statue to get all spells.
There are 3 regions with 4 layers each. In every layer are 5 fishes. When you catch all 5 from every layer, the new spell will be unlocked. When you get last one the Achievement will pop
You must catch every fish with 5 stars rating. You can track it on Statue of Thidon.
It’s just grinding. Every fish has level and it determine fish star points. Go to spot when fish can be found. Start catching it. After catch you will see fish rate (how many stars fish get). If it’s not 5 stars, just repeat. If fish will break line or you will release it, fish will go back to it’s place with the same level, so there is no point of letting it go, even if it’s low level fish.
Get every possible hat in the game. Not sure if Legendary DLC hats count towards it or not. One of hats is a reward for last Mayor quest.
Get every possible ring in the game. Not sure if Legendary DLC rings count towards it or not.
Get every possible necklace in the game. Not sure if Legendary DLC necklaces count towards it or not.
Get every possible fishing rod in the game. Not sure if Legendary DLC fishing rods count towards it or not.
Get every possible item (fishing rod, necklace, ring and hat) in the game. Not sure if Legendary DLC fishing itemscount towards it or not.

If somehow you will be still short of exp, the easies way to farm fast is to catch Feathered Flounder from Kalabor’s Magic Waste Dump.
