Abstract

The effect of temperature on the hatching of eggs of the pike gudgeon, naturally spawned in a tank, was examined at 11-31°C. At 14-27°C the total hatch was over 60%, independent of temperature, with almost 100% hatching normally. Therefore, the optimum hatching temperature for pike gudgeon egg is considered to be in the range of 14-27°C. This is a much broader range of temperatures than is known for other fishes. The pike gudgeon is known to be widely distributed both upstream and downstream in rivers, and it is thought that such a range in hatching temperatures is an adaptation to having such a wide population distribution.
