What does it actually do?
A sardine grinder is used to create a continuous trail of particles, pulp and sardine blood that spreads far into the current, attracting predators by smell (tuna, bonito, swordfish, mackerel, sparidae, etc.).
It also serves to guide the fish to the boat, forming a sort of olfactory "highway" that they follow from the open sea to the source of the broumé, where the lines are.
What's more, using a sardine grinder keeps the fish under the boat longer, as the spread is regular and frustrating (lots of smell, small pieces, but they don't gorge), making the fish less wary and more inclined to bite.
An accessory that helps improve efficiency when fishing at anchor or drifting (tuna scrambling, light drifting, slow trolling, vertical jigging on dentex/dorados, etc.).
A sardine grinder doesn't make the fish appear, but it does concentrate them and hold them in its wake, exactly where you present your baits.
Compared to a "manual" broumé
- More even distribution: the machine sends a sardine puree in a continuous flow or at very tight intervals, thus avoiding "gaps" in the odor trail.
- Controlled particle size: screens and slow grinding produce small pieces that remain in the target water layer and don't sink too quickly to the bottom.
- Less work: instead of constantly cutting or shredding by hand (tiring and less regular), you simply reload the shredder and keep an eye on it.
A typical example: tuna fishing in the Mediterranean, the boat is anchored or drifting, the grinder grinds 3âeuros3.5 kg of sardines directly overboard continuously, creating a wake of bloody mush that the tuna swim up to the boat, where you have one or more lines baited in the broumé.
