The two bigger sizes work well for pike-perch and pike, especially when they are not really hungry or feeding on smaller baitfish. This streamer is a true pike killer in brackish waters like on Rügen/Germany, or in Denmark and the South of Sweden during the cold season from October to February when pike are feeding on smaller fish.
The Salty Baitfish Streamer can be fished anyway you want to use it but my favourite animation is the following: Twitch it hard two or three times and let it sink for 3 to 5 seconds, depending on the depth allowing you to do so. Especially when fishing for big perch in cold water and for pike-perch, the extra-long holding phase will be deadly. This colour Mullet is extremely effective when the water is crystal clear and of course on a sunny day.
