Mussel Spat Ropes Assist Redfin Bully Gobiomorphus huttoni Passage through Experimental Culverts with Velocity Barriers
The application of mussel spat rope for enabling the passage of redfin bully Gobiomorphus huttoni through culverts, which create velocity barriers, was trialled in the laboratory. No fish were able to access the un-roped control pipes whereas 52% successfully negotiated the pipes in the rope treatments. The success of fish ascending treatment pipes suggests mussel spat rope may be effective for...
متن کاملMigration season of whitebait of giant kokopu, Galaxias argentus
Sampling of whitebait from the migrations in a series of West Coast and Southland rivers (Heaphy, Orowaiti, Buller, Hokitika, Wanganui, Okarito, Mataura) showed that whitebait of the giant kokopu migrate late in the spring, beginning to enter rivers during early November and continuing well through December. Amongst 70 whitebait samples containing nearly 9000 whitebait there were only 231 giant...
متن کاملHabitat loss through disruption of constrained dispersal networks.
Large losses of habitat could be caused by land use change that disrupts the dispersal networks used by migratory species. We assessed the relative losses of habitat for diadromous fish (i.e., those migrating between sea and freshwater) due to physical barriers, degradation of migratory passage associated with catchment land use, and site-scale land use characteristics on the West Coast, South ...
