Abstract
Here we assessed the influence of environmental variables on yellow belly flounder (YBF) in the Kaipara Harbour using commercial YBF catch data. This involved creating a YBF catch index and lagging it so water quality and climatic data were compared to periods when YBF were juveniles. Nitrate and the Southern Oscilation Index (SOI) were often related to YBF catch rates (Pearson = 0.4 – 0.6), emphasising the potential influence of land use and SOI positive (La Niña) events to YBF recruitment.
