The Deceitful Predator of the Submerged Lands
One of the most deceitful predators lurking in local waters. The 
Bloodgill is an aggressive predator classified at level 30 in the wetlands. Bloodgills have no need to chase their prey because they lure it in with a blood-like fluid that seeps from their gills.
The closer a victim gets, the stronger the intoxicating effect of the fake blood becomes. Once trapped, escape is almost impossible. Their gill fluid is always in demand, which is why anglers constantly get orders for this fish.
Locating a Bloodgill Fishing Spot
Predatory and peaceful fish require different bait and different fishing techniques. Unlike schools of peaceful fish that must be caught using a float, predatory species strike moving lures. Anglers search across each marked Fishing spot across the Submerged Lands map.
The waters also contain peaceful creatures like the 
Softgrazer that feed in shallow zones. Parasites like swamp 
Leeches feed on slow-moving fish and yield a pungent odor used to prepare scented attractants.
Recommended Baits and Reeling Techniques
Bloodgills attack wobblers without hesitation, so with enough skill they are not especially difficult to catch. Anglers equip the 
Rainbow Fin lure whose bright plumage flutters while reeling to provoke strikes. Another effective predator bait is the 
Flaming Belly which mimics the swimming movement of small prey. Large predators attack this lure without hesitation, only to become hooked themselves.
While reeling, you will need to monitor two indicators: Fish stamina and Line tension. Move the rod in the opposite direction of the fish movement by moving the mouse left and right. Pulling harder in the opposite direction reduces the fish stamina faster.
Once the fish stamina has been fully depleted, you can safely reel it in. Pull the fish close to the boat to complete the catch.
Cargo Storage and Fish Processing
Processing fish in the Grinder yields valuable ingredients. Drag a fish from your boat hold into the processor slot where processing begins automatically. Press and hold [F] to collect the processed resource. Grinding a caught predator produces salvageable 
Jaws with rows of sharp teeth. Anglers can also retrieve floating cargo or snagged resources from the water using the 
Hook Gun.
