New fish

Six new catches can only be caught with a fish trap. They all count as fish (#minecraft:fishes), so cats and fish recipes accept them.

Catch	Found in	Raw food	Cooked food
Raw Trout	Rivers, lakes	2 (0.1)	6 (0.8)
Raw Catfish	Swamps, rivers	3 (0.1)	7 (0.7)
Raw Mackerel	Oceans, cold oceans	2 (0.1)	5 (0.6)
Raw Crab	Oceans, warm oceans	2 (0.1)	6 (0.7)
Raw Lobster	Cold oceans	3 (0.2)	8 (0.9)
Raw Crayfish	Swamps, rivers, lakes	1 (0.1)	4 (0.5)

Food is shown as hunger restored, with the saturation modifier in brackets, the same way vanilla lists cod (2, 0.1) and cooked cod (5, 0.6).

Rainbow Fish

Rainbow Fish

The rarest catch in the mod. It only turns up in a trap fitted with a Netherite Net, and can then appear in any biome. Warm oceans give it twice the weight of other biomes.

Eat it raw for:

Effect	Level	Duration
Absorption	V (10 extra hearts)	2:00
Resistance	II	1:00

It restores 6 hunger with a 1.2 saturation modifier, and you can eat it even when you're not hungry. Keep one for a hard fight.

Its catch chance grows with luck, so pairing it with the best bait helps. With a Netherite Net in a warm ocean, it's about 4% of catches with Worm Bait and about 6.5% with a Nautilus Lure.

Cooking

Every new catch except the Rainbow Fish cooks in a furnace, a smoker (twice as fast) or on a campfire, and gives the same experience as vanilla fish.
