Crab trapping

Crab trapping is a Hunter activity in which players trap crabs in permanently-built traps. Unlike other methods, players cannot fail to catch a crab.

Overview

There are three crabs that can be trapped:

	Crab		Exp.	Location	Requirements	XP/HR
21		Red crab	64	The Pandemonium	Pandemonium	30k (2 traps) 45k (3 traps)
48		Blue crab	136	The Great Conch	Troubled Tortugans	70k-75k (3 traps) 85k-90k (4 traps)
77		Rainbow crab	216	The Crown Jewel	64	150k-160k

Setting up

Players must first build hinged-lid traps over holes at set locations, requiring 10 Construction to do so. Each location has five holes that may be built into traps. Players will also need a saw and hammer, as well as a bucket, a plank, and two nails of any type for each trap. Built traps remain there permanently and cannot be removed; they only need to be built once.

All traps can be built immediately, regardless of level. However, the number of simultaneous active (baited or full) traps is limited by Hunter level:

level	Number of traps
21	2
40	3
60	4
80	5

Setting traps

Red and blue crab traps must be baited with fish offcuts, and rainbow crab traps must be baited with fine fish offcuts, both of which are stackable. After a set period of time, crabs will move towards the baited traps:

Crabs	Time before crabs walk to trap
Red and blue crabs	15 ticks (9s)
Rainbow crabs	25 ticks (15s)

Once a crab is trapped, players must empty the traps to collect the crabs. The player will automatically re-bait a trap after 3 ticks (1.8s), but this can be reduced to just one tick by immediately clicking the trap again.

Strategy

The highest experience rates from crab trapping require using the time between each lap of checking traps to process the caught crabs. Because crab paste is stackable, it's highly recommended to bring a pestle and mortar instead of a knife, as this will result in less effort needed from dropping, and more overall profit per hour.

An inventory setup like the one to the right allows players to most efficiently trap, without much intensity. Players should lay a round of traps, then run from the first to the last trap to check them. Afterwards, players should return to standing in front of the first trap, and crush the crabs of each colour, making sure to leave one crab of each colour next to the pestle and mortar.

Because crabs traps can never fail to catch a crab, the guild hunter outfit has no effect, nor does anti-odour salt. As such, players should prioritize maintaining run energy. The graceful outfit may be useful for players with a low Agility level.

Rewards

Crabs can be cut with a knife to obtain raw crab meat (which can then be cooked at a range or fire), or crushed with a pestle and mortar to obtain crab paste.
