I am new to bass fishing so please tolerate my ignorance.This is a multiple question,so please bear with me.(1)Is there a fish management system in the upper Nepean river,either by a goverment body or local clubs.(2) I understand that bass travel downstream to breed.There are at least 4 weirs between Menangle & Penrith.How does this affect their breeding cycle.(3)Does anyone stock the river with fish. ???
