Product Details and Uses

Dynamite Baits Big Fish Marine Halibut & Hemp Groundbait 1.8kg

When it comes to drawing heavy feeding fish into your swim and holding them there, few ingredients match the pure pulling power of fish oil and natural hemp. The Dynamite Baits Big Fish Marine Halibut & Hemp Groundbait combines two of the most successful fish attractors of all time—premium Marine Halibut and legendary Frenzied Hemp—into one high-value, hard-hitting 1.8kg bag.

This rich, dark groundbait is packed with quality ingredients, including heavy ratios of crushed hempseed and crushed Marine Halibut pellets. Once mixed, it releases a potent combination of heavy fish oils and natural hemp attractants that travel rapidly through the water column. It is an incredibly versatile mix designed to create a heavy bed of high-protein attraction on the deck without overfeeding the fish, making it a reliable choice for big-fish anglers nationwide.


Technical Specifications

  • Weight: 1.8kg (High-value bulk bag)

  • Core Ingredients: Crushed Frenzied Hempseed, crushed Marine Halibut Pellets, high-protein fishmeals, and amino acids

  • Texture: Medium-coarse (highly adaptable depending on water addition)

  • Oil Content: High (packed with natural hemp oils and marine fish oils)

  • Target Species: Barbel, Carp, Specimen Chub, Bream, and Tench

  • Application: Feeder fishing, method feeders, balling-in, spod mixes, and stick mixes


Where & How to Use Marine Halibut & Hemp Groundbait

  • River Barbel & Chub Feeder Fishing: The absolute number-one choice for big river venues. The heavy, oily nature of the mix helps it hold the river bed in strong currents, leaking a powerful scent trail downstream that guides barbel straight to your hook bait.

  • Carp Method Feeder & Stick Mixes: Excellent for packing around a Method feeder or compressing into PVA mesh bags for carp fishing. The crushed hemp particles create a active, fizzing bed of bait that breaks down cleanly on the lake bed.

  • Open-End Feeder Bream Tactics: Ideal for plugging the ends of open-end cage feeders when caching large payloads of micro pellets, dead maggots, or chopped worm into deep stillwaters and reservoirs.


Pro Tip from the Gerry’s Fishing Team

Because this groundbait contains a large amount of real crushed pellets and hemp, it is quite an absorbent mix. To get the perfect texture for river or feeder work, we highly recommend a two-stage mixing process.

Empty your groundbait into a large mixing bowl, add water gradually while mixing vigorously, and leave it to stand for 10 to 15 minutes. This gives the crushed ingredients time to fully absorb the moisture. After standing, pass the mix through a groundbait riddle. This breaks up any heavy lumps and injects air into the groundbait, resulting in a perfectly fluffy, active mix that exits your feeder cleanly every single time on the river bed.


Frequently Asked Questions

Can I use this groundbait in a PVA bag?

Yes, but you must ensure the groundbait is mixed “dry” using oil-based liquids (like Dynamite’s liquid attractants or hemp oil) rather than water. If you mix it with water, it will dissolve your PVA bag instantly.

Is this mix suitable for summer or winter fishing?

While it works year-round, its performance absolutely skyrockets during the warmer summer and autumn months. The high oil content from the halibut pellets and hemp leaks aggressively in warm water temperatures, making it devastatingly effective when river barbel and carp are feeding hard.

Does it hold together well in deep or fast-flowing rivers?

Yes. By adding slightly more water during the mixing stage and compressing it firmly, you can create a sticky, heavy mix that will easily reach the bottom of deep or fast-flowing river glides before breaking down.

Can I add extra loose offerings to this groundbait?

Absolutely. This mix is the perfect carrier for extra loose feed. It blends brilliantly with 2mm–4mm Marine Halibut pellets, whole hempseed, sweetcorn, chopped worms, or dead maggots to create an even more substantial feeding area.
