Welcome to Gerry’s Fishing! When it comes to commercial match fishing and targeting wary fish in clear water, very few groundbaits carry the legendary reputation of Dynamite’s Swim Stim range. The Swim Stim Amino Black Groundbait is a naturally balanced fish attractant engineered to give you a distinct edge on heavily pressured venues. Its incredible effectiveness is a direct result of advanced feeding triggers combined with the precise way the ingredients mix and interact with water to create an irresistible, clouding carpet of feed. It is no surprise that this uniquely effective range continues to fly off our shelves season after season.
What sets this groundbait apart is the inclusion of exclusive Koi Technology, meaning it is packed to the brim with premium proteins, fishmeals, and vital amino acids that fish crave. The dark black colour profile is a massive advantage; it creates a subtle, low-viz area on the lake bed, giving fish the confidence to settle and feed over your spot without fearing they are exposed to predators against a bright background. While it is an absolute powerhouse for commercial carp, Swim Stim Amino Black is incredibly versatile and equally devastating when targeting skimmers, quality bream, and tench on both stillwaters and canals.
Product Type: Premium fishmeal-based groundbait.
Colour: Intense Black (ideal for clear water, winter fishing, or dark lake beds).
Key Ingredients: Enhanced with Koi Technology and packed with pure amino acids.
Mix Profile: Highly adaptable; can be mixed overwet for a sloppy cloud, perfectly damp for a fast breakdown, or overwritten into a durable paste.
Target Species: Commercial Carp, F1s, Bream, Skimmers, Tench, and Roach.
The Method & Hybrid Feeder: A phenomenal choice for moulding around a Method or Hybrid feeder on commercial fisheries. The fine particles break down cleanly on the deck, releasing powerful aminos right next to your hook bait.
Clear Water Margins: Perfect for cupping into the margins during the spring and summer. The black color prevents fish from spooking in shallow, clear water, allowing you to build a dense, heavy feeding zone.
Winter & Cool Water Sessions: When lakes clear down in the colder months, standard light-coloured groundbaits can scare fish off. The Amino Black blends seamlessly with the bottom, making it an elite winter choice for skimmers and F1s.
Pro Tip: To get the absolute best out of Swim Stim Amino Black, mix it in two separate stages. Add your water gradually, give it a vigorous mix, and let it stand for 15 minutes to allow the fishmeals to fully absorb the moisture. Then, push the mix through a groundbait riddle. This breaks up any small clumps and introduces air, resulting in a beautifully fluffy, consistent texture that explodes off the feeder or forms perfect balls for cupping in.
Q: Can this groundbait be used to make a hook bait paste?
A: Yes, absolutely! Because of its high fishmeal content and fine texture, you can continue adding water past the standard groundbait stage to create a brilliant, soft, high-attract paste that wraps perfectly around a pole rig hook bait.
Q: Will the black colour wash away or fade under water?
A: No, the deep black colour holds exceptionally well on the lake bed, maintaining its dark, stealthy profile throughout your session to ensure feeding fish remain confident and comfortable over your feed.
Q: Is this groundbait only effective on commercial carp waters?
A: Not at all. While it is a staple for commercial carp and F1 tactics, the heavy amino profile and dark colour make it incredibly effective for wild skimmers, big bream, and tench on natural lakes, canals, and slow-moving rivers.
