The sea worm is the most famous and easy bait for catching a mullet. All kinds of fish are caught on the sea worm on the Black Sea and, what's more, the worm can be bought in fishing shops, markets, all kinds of street tents. On the sea worm catch all the local anglers, so if you are a fishing tourist and do not know where you can get a worm, ask them, they willingly talk about the points of sale and even advise where they think is better.
And the fact is that you can get the sea-worm itself, of course. But very long. Who wants to lose their precious time. Therefore, right on the coast you can meet local "professionals", who practically with you will get a sea worm and immediately sell. In general, the production options are many.
The sea worm is also called "Nereid" and "Pesky". This bait is rather dense and is planted mainly "stocking", otherwise the small piece quickly gnaws the worm.
