Abstract
The present study quantitatively describes a significant stock of carp (Cyprinus carpio L.), an exotic pest species, in a temperate riverine floodplain wetland. Intensity and duration of flooding influenced relative abundance, distribution and recruitment. Average growth (mm) in length was described with the von Bertalanffy growth model for males (L∞ = 489, k = 0.249, t0 = –0.519), and females (L∞ = 594, k = 0.177, t0 = –0.609) to age 28. Variation in growth was described with a lognormal distribution of k. Total mortality (Z year–1) was 0.268–0.407 for males, 0.311–0.422 for females, 3.24 for age-0 juveniles and 1.80 for age-1 juveniles. Natural mortality (M year–1) was 0.199 for males and 0.262 for females. Fishing mortality (F year–1) was <0.05 for males and 0.11–0.30 for females. Gonadal changes indicated extended spawning seasons peaking in September 1999 and October 2000. Median sizes and ages at initial maturation were 307 mm, 584 g and 1.1 years for males and 328 mm, 688 g and 2.7 years for females. Sex ratio varied significantly with age from equal as juveniles to a significant male-bias as adults. This description will enable better stock assessment and development of simulations that evaluate potential pest management strategies.
Extra keywords: age, biomass, environmental water allocation, exotic pest fish, flooding, growth, mortality, reproduction, sex ratio, spawning season.
