Overall Objective:
Estimate the status of the scallop stocks in the Marlborough Sounds, Golden Bay, and Tasman Bay.
Specific Objectives:
1. Conduct a biomass survey in the Marlborough Sounds that will provide estimates of current relative and absolute abundance (numbers and biomass in tonnes greenweight and meatweight), length frequency profile, density, and distribution of recruited and pre-recruit scallops in the Marlborough Sounds.
2. Estimate the biomass of scallops in the Marlborough Sounds using a range of commercial density thresholds from 0.00 to 0.2 recruited scallops per square metre.
3. Compare the estimates from Objective 1 with other relevant data from previous surveys and, if available, all relevant fine scale catch data.
4. Conduct a biomass survey in Golden Bay that will provide estimates of current relative and absolute abundance (numbers and biomass in tonnes greenweight and meatweight), length frequency profile, density, and distribution of recruited and pre-recruit scallops in Golden Bay.
5. Estimate the biomass of scallops in Golden Bay using a range of commercial density thresholds from 0.00 to 0.2 recruited scallops per square metre.
6. Compare the estimates from Objective 4 with other relevant data from previous surveys and, if available, all relevant fine scale catch data.
7. Conduct a biomass survey in Tasman Bay that will provide estimates of current relative and absolute abundance (numbers and biomass in tonnes greenweight and meatweight), length frequency profile, density, and distribution of recruited and pre-recruit scallops in Tasman Bay.
8. Estimate the biomass of scallops in Tasman Bay using a range of commercial density thresholds from 0.00 to 0.2 recruited scallops per square metre.
9. Compare the estimates from Objective 7 with other relevant data from previous surveys and, if available, all relevant fine scale catch data.
10. For each survey, collect bycatch information in a form suitable for later analysis.
