Collection of Environmental Data
Besides the catch data and biological data being collected in long-line survey, data on environmental parameters will be collected as follows:
- Salinity, Temperature and Depth (STD) data, per day per set.
- Sea Surface Temperature (SST) data at hourly interval from the commencement to completion of voyage.
- Data on current direction and speed, one observation every day (sets are to be made at specific depth).
- Secchi disc observation (3 readings) for every set made after setting line.
Result reporting: As per Annexure II
