      Abstract
      We conducted a boat electrofishing survey of the Ohau Channel, which flows from Lake Rotorua to Lake Rotoiti, on 11 December 2008. The purpose of this was to repeat a survey that took place on 13 December 2007 concerning the longitudinal pattern in densities of common smelt (Retropinna retropinna) and common bully (Gobiomorphus cotidianus). We caught 776 fish comprising three native species and three introduced species in 2.03km of fished distance at a total of 10 sites. Native species caught were common smelt, common bully and longfin eel (Anguilla dieffenbachii) and introduced species were rainbow trout (Oncorhynchus mykiss), goldfish (Carassius auratus) and mosquitofish (Gambusia affinis). The total area fished was 8,133 m² (0.813 ha) giving an estimated density of 9.5 fish 100 m⁻².
