Overview

Overall Objective:
Estimate sediment resuspension and plume coverage by inshore trawl fisheries in Hawke Bay, Tasman Bay and Golden Bay, and off the Otago coastline.

Specific Objectives:
1. To complete a review of methods to estimate the quantity of sediment resuspended by trawling activities.
2. Collate all surficial sediment data available in Hawke Bay, Tasman Bay and Golden Bay, and off the Otago coastline.
3. Review recent work describing trawl gear used in New Zealand and refine gear characterisation to ensure this reflects gear use in Hawke Bay, Tasman Bay and Golden Bay, and off the Otago coastline.
4. Using estimation approaches reviewed in Specific Objective 1, sediment data collated in Specific Objective 2, and gear characteristics refined in Specific Objective 3, estimate sediment resuspension and plume coverage by inshore trawl fisheries in Hawke Bay, Tasman Bay and Golden Bay, and off the Otago coastline.
5. Broader outcomes.

Rationale:
A physical impact of bottom trawling on soft sediments is the mobilisation of sediment into the water column, which may have widespread effects on biodiversity and productivity. Currently there is little information on sediment resuspension and plume coverage from bottom trawling in New Zealand. Estimating sedimentation from bottom trawling is a necessary first step before the ecological implications of suspended sediment from fishing activity (e.g., effects on shellfish beds, seabird foraging) can be assessed.

This project aims to estimate the quantity of sediment mobilised into the water column by inshore bottom trawl fisheries in Hawke Bay, Tasman Bay and Golden Bay, and off the Otago coastline. In so doing this project will contribute towards the understanding of the impacts of trawling activities and enable further assessment of potential adverse effects.

Note:
This is a Future Procurement Opportunity (FPO). A FPO is an alert to suppliers of a potential upcoming procurement activity, though does not represent a commitment by MPI to procure, however provides an indication to the market about the potential future activity. Suppliers can subscribe to this FPO, and MPI may use this list to assist with market research. When the RFP is released, the FPO will be linked to the RFP so that those suppliers who have subscribed to the FPO will get automatically notified of the RFP being released.
