Fishing Loots & Chances:

Oceach = Ocean & Beach

So if you want Neat, Just type:
/function adv_overend_fish (All Overworld & End Fish) & /function adv_deadther_fish (Dead & Nether Fish)

Crafteable Resources:

All the recipes above are Shapeless, Some recipes are Very Useful, So now Fishing will help your Survival More Than Ever!

Only this recipe is Shaped & Only Works on the Crafting Table, So it Doesn't Work in Inventory Crafting!

Cooking Fish:

V2: Plentiful Cooking Update

2 Cooked Salmon
Pike = 3 Cooked Cod
Angler Fish & Catfish = 3 Cooked Salmon
Also Works in Campfire & Soul Campfire!

Now All New Fish Can Be Eaten
But Be Careful, Most are Harmful if Eaten!

Mostly causes Hunger lll for 15 Seconds & Nausea ll for 10 Seconds. Some Fish also cause Poison ll for 10 Seconds

Spookyfin is also the same, but Doesn't cause Poison, but Blindness lll for 10 Seconds

Some Nether Fish are the same, but Doesn't cause Poison/Blindness, but Wither ll for 10 Seconds

♦ This Fishing Pole also has Cooldown for 15 Seconds (To Anticipate Spam Fishing)

(Because the Items you get will be Scorched By The Lava)

♦ This Bobber is Eternal, doesn't receive Damage / Knockback from Any Source

♦ Sometimes Bobber Despawn also because your Fishing Angle is Not Right
