Fish Passage Problems in New Zealand
Proceedings of the International Symposium on Fishways '95
The Organizing Committee for International Symposium on Fishways '95 in Gifu
Significant progress has now been made on the development of designs for fish passes for New Zealand freshwater fish. Some of this work has used concepts presented at the last Gifu Conference. Salmon and trout fish passes have been based upon overseas designs. Designs fro native fishes capable of climbing and those only capable of swimming, have been developed and tested in New Zealand. There are also some areas which have to be restocked by trucking the juvenile migrating fish upstream. One significant problem area is the downstream migration of adult eels past hydro power stations. Recent studies have investigated the use of trap nets followed by trucking downstream, to protect adult migrating eels.
