Embarking on a fishing adventure in Old School RuneScape (OSRS) can be an exciting and rewarding experience, with the 'Catch a manta ray' task in the Fishing skill offering a unique challenge. The Manta ray, found only in the deep waters of the Karamja island, is a coveted and sought-after catch by many OSRS players. The task requires fishing a manta ray from a fishing trawler, a specialized type of boat that can be rented from Port Sarim or Port Karamja. This comprehensive guide will walk you through the process, offering tips, and tricks to catch a manta ray in a fishing trawler.

Before setting sail, ensure you have the necessary skills and equipment. To acquire a fishing trawler, you'll need at least 70 Fishing and 60 Agility. Additionally, having a good supply of bait, such as anchovies or sardines, and equipped with the best fishing gear, like a harpoon or a fishing rod with manta ray bait, will significantly improve your chances of catching a manta ray.

Understanding the Fishing Trawler
Fishing trawlers in OSRS are specific boats designed for deep-sea fishing. They're bigger and more robust than usual fishing boats, equipped with advanced features, such as harpoon launcher slots and an anchor. To rent a fishing trawler, speak to the boatman in Port Sarim or Port Karamja and pay 2,000 coins for 5 minutes of trawler use.

Once on board, equip your fishing gear, light the tinderbox to start the harpoon launcher, and cast your bait into the water. Keep an eye out for sea creatures swimming nearby. When a manta ray appears, click on it, and your character will attempt to harpoon and reel it in.
Navigating the Trawler

The fishing trawler operates differently than regular OSRS boats. To control the trawler, right-click on the boatman and select 'control'. You'll be prompted with an interface displaying your trawler's speed and heading. Use 'w', 'a', 's', and 'd' keys to steer the trawler, and 'space' to stop or the arrow keys to change speed.
It's essential to find the optimal depth and location for manta ray fishing. Manta rays can be found deep underwater, near Karamja's coasts. To reach these deep waters, sail your trawler towards Karamja island, then head south, keeping an eye on your depth gauge. Once you're in the desired location, slow down your trawler, equip your fishing gear, and start casting your bait.
Catching the Manta Ray

When a manta ray appears, click on it to launch your harpoon. Once hit, the manta ray will thrash around, trying to escape. Immediately start reeling it in using your fishing rod. Be prepared to handle the fish's struggles; the more significant the manta ray, the harder it will fight. If you successfully reel it in, it will be caught, and you'll gain fishing experience.
Note that catching a manta ray isn't easy. It requires patience, as waiting for a manta ray to appear can take time. Additionally, manta rays have a unique 1000 - 125,000 weight, unlike other fish. This weight range makes it crucial to check your inventory space before attempting to catch one, as you might not be able to store the manta ray if your inventory is full.
Tips and Tricks

To increase your chances of catching a manta ray, consider the following tips:
Use the best bait: villager fishing supplies, like anchovies or sardines, have the highest chance of attracting a manta ray.








Relocate often: If you don't see any manta rays after a few minutes, switch your trawler's location. Manta rays can be found in various spots around Karamja, so exploring different areas can increase your chances.
Prioritize the right spots: Shifting tides can reveal new underwater anomalies, exposing new areas with increased manta ray appearances. Watch out for seaweed clusters, as they often hide potential manta ray spawn points.
Increase your Fishing level: The higher your Fishing level, the better chance you have of catching a manta ray. Strive to improve your Fishing skill to boost your chances.
In your quest to catch a manta ray in OSRS, remember that patience and persistence are key. Keep practicing your fishing skills, experiment with different bait and locations, and never give up. Happy fishing!
