Fisch Cataclysmic Fish – Complete (March 2026) Guide

If you’re looking to catch the most legendary fish in Fisch, you’ve come to the right place! As someone who has spent countless hours exploring the depths of this Roblox fishing adventure, I’m excited to share everything you need to know about all 5 Cataclysmic Fish in Fisch. These aren’t just any ordinary catches – they’re the rarest, most valuable fish in the game, requiring special events and strategies to obtain.

In this comprehensive guide, I’ll walk you through exactly how to trigger the elusive Earthquake Events, which baits work best for each Cataclysmic Fish, and the strategies that will help you add these legendary creatures to your collection. Whether you’re a seasoned angler or just starting your Fisch journey, this guide will give you the edge you need to master the cataclysmic fishing experience.

What Are Cataclysmic Fish in Fisch?

Cataclysmic Fish represent the highest tier of rarity in Fisch, introduced in the game’s Version 1.53 update in October 2026. These legendary creatures are unlike any other fish in the game – they cannot be caught through normal fishing methods and require special world events to spawn. With values reaching up to 224,000 C$ and weights exceeding 2.5 million kg, these fish are the ultimate prize for any dedicated angler.

What makes Cataclysmic Fish particularly special is their unique spawning mechanics. Instead of appearing randomly like other fish, they only become catchable during specific events: the Earthquake Event and the Eruption Event. This means you’ll need teamwork, strategy, and a bit of patience to add these legendary creatures to your bestiary.

All 5 Cataclysmic Fish: Complete Overview (March 2026)

Here’s a quick reference table of all 5 Cataclysmic Fish in Fisch, including their key characteristics:

Fish Name	Best Bait	Preferred Time	Location	Avg. Weight	Value (C$)
Ashclaw	Coal	Any	Roslit Volcano	350,000 kg	224,000
Lusca	Meteor/Stag Beetle	Day	Ocean	2,500,000 kg	195,000
Skeletal Serpent	None	Any	Regionless	25,000 kg	193,750

Charybdis	Meteor/Stag Beetle	Night	Ocean	2,500,000 kg	196,875

Understanding Cataclysmic Fish Events

There are two main types of events that spawn Cataclysmic Fish in Fisch:

1. Earthquake Event

The Earthquake Event is the primary method for catching most Cataclysmic Fish. During this event, you’ll see the message: “An Earthquake is happening, its awakening cataclysmic deep sea fish!” This event allows you to catch Lusca, Akkorokamui, and Charybdis in ocean areas.

2. Eruption Event (Ashclaw Hunt)

The Eruption Event is specific to catching Ashclaw and occurs in the Roslit Volcano area. You’ll know it’s active when you see: “The Rock Volcano trembles violently — Arcten stirs within the magma! Catch it before the eruption begins!”

How to Trigger Earthquake Events in Fisch?

Triggering these events requires coordination and teamwork. Here’s exactly how to do it:

Step 1: Form a Group

You need at least 5 players fishing together to trigger Cataclysmic Fish events. This isn’t just a suggestion – it’s a requirement based on the game’s mechanics.

Step 2: Choose Your Location

• For Earthquake Event: Gather in any ocean area
• For Eruption Event: Meet at Roslit Volcano (coordinates: -1875, 165, 380)

Step 3: Fish Together

All group members must fish in the same general area. The more players fishing together, the higher the chance of triggering an event.

Step 4: Wait for the Event

Events have a base spawn chance of 1/60,000 (0.00167%) per second, but this increases with each additional player:

• 1 player: 0.00185% chance per second
• 5 players: 0.00282% chance per second
• 10 players: 0.00478% chance per second
• 20 players: 0.01371% chance per second

Step 5: Watch for Visual Cues

When an event triggers, you’ll see screen shaking effects and a server notification. This is your signal that Cataclysmic Fish are now catchable!

Detailed Guide to Each Cataclysmic Fish

1. Ashclaw: The Volcanic Beast

Characteristics:

• Best Bait: Coal
• Preferred Time: Any
• Location: Roslit Volcano (coordinates: -1875, 165, 380)
• Average Weight: 350,000 kg
• Value: 224,000 C$ – Progress Penalty: -90%

How to Catch Ashclaw: Ashclaw is unique among Cataclysmic Fish as it has its own dedicated event – the Eruption Event. To catch this fiery beast:

1. Gather Coal Bait: Coal is essential for catching Ashclaw. You can obtain Coal by:
   • Opening Volcanic Geodes (caught while fishing in Roslit Volcano)
   • Purchasing from the Travelling Merchant
2. Trigger the Eruption Event: Assemble 5+ players at Roslit Volcano and fish together until you see the eruption notification.
3. Use the Right Rod: Ashclaw has extremely high resilience and a -90% progress penalty. I recommend using:
   • Rod of Depths
   • No-Life Rod
   • Seraphic Rod
   • Ruinous Oath
   • Heaven’s Rod
4. Add Enchantments: Enhance your rod with:
   • Resilient enchantment
   • Mystical enchantment
   • Steady enchantment
   • Blessed Song enchantment

Pro Tip: Ashclaw was added in Version 1.53 and is the newest Cataclysmic Fish. Many players consider it the most challenging due to its specific location and high resilience.

2. Lusca: The Three-Headed Terror

Characteristics:

• Best Bait: Meteor or Stag Beetle
• Preferred Time: Day only
• Location: Ocean areas
• Average Weight: 2,500,000 kg
• Value: 195,000 C$ – Progress Penalty: -95%

How to Catch Lusca: Lusca is a massive, tentacled beast that only appears during daylight hours. Here’s how to catch it:

1. Time Your Attempt: Lusca can only be caught during in-game daytime. Make sure to trigger the Earthquake Event during the day.
2. Prepare Meteor or Stag Beetle Bait: These are the only baits that work for Lusca. Meteor bait can be obtained from various events, while Stag Beetles can be caught or purchased.
3. Assemble Your Team: Get 5+ players together in an ocean area.
4. Trigger Earthquake Event: Fish together until the event triggers.
5. Use High-Tier Rods: With a -95% progress penalty, you’ll need the best rods available. The same rods recommended for Ashclaw work well here.

Pro Tip: Lusca is one of the heaviest fish in the game at 2.5 million kg, making it an impressive trophy despite having a slightly lower value than some other Cataclysmic Fish.

3. Skeletal Serpent: The Mysterious Bone Fish

Characteristics:

• Best Bait: None (event-only spawn)
• Preferred Time: Any
• Location: Regionless (can appear anywhere)
• Average Weight: 25,000 kg
• Value: 193,750 C$ – Progress Penalty: Varies

How to Catch Skeletal Serpent: The Skeletal Serpent is unique among Cataclysmic Fish because it has no bait preferences and can appear anywhere during events.

1. No Bait Needed: Unlike other Cataclysmic Fish, the Skeletal Serpent doesn’t require specific bait. Just fish with any bait during an Earthquake Event.
2. Location Flexibility: This fish can appear in any body of water during an Earthquake Event, giving you more flexibility in where you fish.
3. Trigger Earthquake Event: Assemble your team and trigger the event as usual.
4. Be Ready for Anything: Since it can appear anywhere, stay alert during the entire event duration.

Pro Tip: The Skeletal Serpent has the lowest weight among Cataclysmic Fish but still offers excellent value. It’s often considered the “easiest” Cataclysmic Fish to catch due to its lack of specific requirements.

4. Akkorokamui: The Legendary Sea Monster

Characteristics:

• Best Bait: Meteor or Stag Beetle
• Preferred Time: Any
• Location: Ocean areas
• Average Weight: 2,500,000 kg
• Value: 194,375 C$ – Progress Penalty: -95%

How to Catch Akkorokamui: Akkorokamui is based on Japanese folklore and represents one of the most impressive catches in Fisch.

1. Prepare Your Bait: Like Lusca and Charybdis, Akkorokamui requires Meteor or Stag Beetle bait.
2. Ocean Location Only: This fish can only be caught in ocean areas during Earthquake Events.
3. No Time Restrictions: Unlike Lusca and Charybdis, Akkorokamui can be caught at any time of day.
4. Team Up: Get your 5+ player team together in an ocean area.
5. Trigger and Fish: Once the Earthquake Event starts, fish with your prepared bait.

Pro Tip: Akkorokamui offers a great balance of value and availability. Since it has no time restrictions, it’s often more accessible than Lusca or Charybdis for players with limited gaming schedules.

5. Charybdis: The Nighttime Predator

Characteristics:

• Best Bait: Meteor or Stag Beetle
• Preferred Time: Night only
• Location: Ocean areas
• Average Weight: 2,500,000 kg
• Value: 196,875 C$ – Progress Penalty: -95%

How to Catch Charybdis: Charybdis is the nocturnal counterpart to Lusca, offering the highest value among the ocean-based Cataclysmic Fish.

1. Night Time Only: Charybdis can only be caught during in-game nighttime. Plan your event accordingly.
2. Same Bait as Others: Use Meteor or Stag Beetle bait, just like with Lusca and Akkorokamui.
3. Ocean Location: Fish in ocean areas during the Earthquake Event.
4. Maximize Your Chances: Since Charybdis has the highest value among the three ocean Cataclysmic Fish, it’s worth the extra effort to time your event for nighttime.

Pro Tip: Charybdis offers the highest value (196,875 C$) among the ocean-based Cataclysmic Fish, making it a prime target for players focused on maximizing their in-game wealth.

Essential Equipment for Catching Cataclysmic Fish

Recommended Fishing Rods

Cataclysmic Fish have extreme progress penalties (-90% to -95%) and high resilience, making them nearly impossible to catch with standard rods. Here are the best options:

1. Rod of Depths – Excellent choice with good all-around stats
2. No-Life Rod – High resilience and control
3. Seraphic Rod – Great balance of stats
4. Ruinous Oath – High power and resilience
5. Heaven’s Rod – Top-tier performance

Important Note: As of Version 1.53, many rods received significant buffs:

• Rod of Depths: Added 30% chance for Abyssal
• Cinder Block Rod: Luck increased from 100 to 1000
• Various lure and resilience improvements across multiple rods

Essential Enchantments

To maximize your chances of catching Cataclysmic Fish, add these enchantments to your rod:

1. Resilient – Counters the fish’s high resilience
2. Mystical – Improves catch rate
3. Steady – Reduces progress penalty
4. Blessed Song – General catch improvement

Bait Management

Proper bait management is crucial:

• Coal: Essential for Ashclaw (obtain from Volcanic Geodes or Travelling Merchant)
• Meteor/Stag Beetle: Required for Lusca, Akkorokamui, and Charybdis
• Stock Up: These events are rare, so always have extra bait prepared

2026 Advanced Strategies for Cataclysmic Fishing

1. Private Server Coordination

Using a private server can significantly improve your Cataclysmic fishing experience:

• Controlled Environment: No random players interfering
• Better Coordination: Easier to organize 5+ players
• Extended Sessions: No server time limits

2. Time Management Strategies

Since some Cataclysmic Fish have time restrictions:

• Lusca: Plan events for daytime
• Charybdis: Schedule events for nighttime
• Ashclaw/Akkorokamui/Skeletal Serpent: Flexible timing

3. Team Composition

Build an effective team for Cataclysmic fishing:

• Minimum 5 Players: Required for event triggering
• Optimal 10+ Players: Significantly increases spawn chances
• Role Specialization: Some players can focus on bait gathering while others fish

4. Event Duration Management

Cataclysmic Fish Hunt events last approximately 30 minutes. Use this time wisely:

• First 10 Minutes: Focus on your primary target
• Middle 10 Minutes: Try for secondary targets
• Final 10 Minutes: Make any last attempts before despawn

Common Mistakes to Avoid

1. Insufficient Team Size

Trying to trigger events with fewer than 5 players won’t work. Always ensure you have enough participants.

2. Wrong Bait Usage

Using incorrect bait is one of the most common mistakes. Double-check bait requirements:

• Ashclaw: Coal only
• Ocean trio: Meteor or Stag Beetle
• Skeletal Serpent: No bait needed

3. Ignoring Time Restrictions

Forgetting that Lusca (day) and Charybdis (night) have time restrictions can waste entire events.

4. Poor Rod Selection

Using standard rods for Cataclysmic Fish is practically impossible due to extreme progress penalties.

5. Bad Location Choices

Make sure you’re in the right area:

• Ashclaw: Roslit Volcano
• Ocean trio: Ocean areas
• Skeletal Serpent: Any location
