Oriental Weatherloach Misgurnus anguillacaudatus 65 Oriental Weatherloach were recorded during survey. The highest abundance was recorded at Corduroy Swamp (n=38) (Table 2, Figure 18). Low numbers of this species (between 1 and 9 individuals) were recorded at all other sites with the exception of Turners Lagoon where it was not recorded. Figure : Oriental Weatherloach CPUE (number of fish/hr) for Gunbower Forest fish monitoring, March, 2015. Length-frequency indicates a fragmented population structure with the majority of individuals (90%) within the 85 to 125mm size range being 1-2 year old fish. Low numbers of young of year fish were recorded (n=4). This species is recorded living in excess of 10 years in captivity (Gomon and Bray, 2011). The absence of older cohorts (130 to 160mm – 3 years plus) and low numbers of older cohorts suggests intermittent recruitment into the population and/or dispersal periods in intervening years (Figure 19). Figure : Length-frequency distribution for Oriental Weatherloach, Gunbower Forest, March 2015. Broken line indicates size at maturity.
