Zander resembles pike somewhat as far as outward appearance and behavior is concerned, but it is not related. Just like perch, it has two separate dorsal fins with the front one containing spines. Zanders can grow up to 120 centimeters in length. Sometimes there are large differences in length in the first year due to a lack of prey fish or because the prey fish are too large to eat. It is not unusual to have an entire year class no larger than ten centimeters while the young zanders that get sufficient food grow to 15-20 centimeters. Zander is very tasty and therefore intensely fished in the IJsselmeer.
