Integrated Catchment Management

Boat Trip

LAND-MARINE INTERACTIONS: TASMAN BAY ICM RESEARCH 

(By invitation to ICM programme participants, marine sector groups, iwi and others interested, subject to numbers - please contact Paul Gillespie at Cawthron if interested and not specifically listed below)


Boat trip to the Motueka River plume, Cawthron's monitoring buoy and TDC Aquaculture Management Areas including discussion about the scallop fishery and mussel spat catching.

ICM research for the Motueka catchment extends into Tasman Bay where we are investigating the impacts of catchment land use and the related discharge of freshwater, sediment, nutrients and pathogens to the coast via the Motueka River plume.

ICM marine research includes assessing effects of the river plume (including low flow and flood conditions) on river delta and offshore habitats. Particular attention is paid to relationships that may affect the sustainability of shellfish resources and potential development of Aquaculture Management Areas (AMAs). This has included research on nickel and chromium flushed from the upper catchment Red Hills. Modelling of Tasman Bay circulation and ecosystem productivity for aquaculture is also being carried out.

This field trip is an opportunity to share the science knowledge emerging from this research and discuss catchment management implications with shellfish resource managers, TDC coastal policy-makers, Government departments and other interested groups.

Tentative schedule:
08:00 Cougar Cruises boat leaves Port Nelson

0845 Stop at Motueka River mouth/delta and proceed slowly along a transect seaward through the plume to discuss the spatial extent of effects to water column and seabed habitats

0930 Stop at ICM monitoring buoy site to discuss long term data collection facility and have morning tea

1015 Discuss scallop and oyster enhancement programmes

1100 Travel through central aquaculture management area noting boundaries

1130 Stop at mussel spat catching site to discuss procedures and possible plume effects
