Penstock and Shannon Lagoons – Native fish monitoring
Each year we monitor the native fish populations at Penstock and Shannon lagoons. The three species of fish we are looking for are, the spotted galaxias, the Shannon paragalaxias and the Great Lake paragalaxias. This year we caught a very large number of both the spotted galaxias and more pleasingly, the threatened Shannon paragalaxias. This is the highest numbers of this species that have been found at for many years! The third species, the Great Lake paragalaxias, which is much harder to find and occurs only in low numbers in these lagoons, was found within both lagoons. This is a great outcome and indicates the overall health of these waters is good.
