- 1.
Length and width of each trawl panel (in sufficient detail to allow calculation of the angle of each panel with respect to water flow.)

Details of streamers used inside the trawl (design, location on panels, indicate 'nil' if streamers are not in use); streamers prevent krill fouling the mesh or escaping.

Observation steps and frequency
Holding tank volume | |
|---|---|
At the start of fishing | Measure the width and length of the holding tank (if the tank is not rectangular in shape, then additional measurements may be required; precision ± 0,05 m) |
Every month328 | Estimate the volume-to-mass conversion derived from the drained mass of krill in a known volume (e.g. 10 litres) taken from the holding tank |
Every haul | Measure the depth of krill in the tank (if krill are held in the tank between hauls, then measure the difference in depth; precision ± 0,1 m) |
Estimate the green weight of krill caught (using equation) | |
Flow meter328 | |
Prior to fishing | Ensure that the flow meter is measuring whole krill (i.e. prior to processing) |
More than once per month328 | Estimate the volume-to-mass conversion (ρ) derived from the drained mass of krill in a known volume (e.g. 10 litres) taken from the flow meter |
Every haul329 | Obtain a sample from the flow meter and: |
measure the volume (e.g. 10 litres) of krill and water combined | |
estimate the flow meter volume correction derived from the drained volume of krill | |
Estimate the green weight of krill caught (using equation) | |
Flow meter329 | |
Prior to fishing | Ensure that both flow meters (one for the krill product and one for the water added) are calibrated (i.e. show the same, correct reading) |
Every week328 | Estimate the density (ρ) of the krill product (ground krill paste) by measuring the mass of a known volume of krill product (e.g. 10 litres) taken from the corresponding flow meter |
Every haul329 | Read both flow meters, and calculate the total volumes of the krill product (ground krill paste) and that of the water added; density of the water is assumed to be 1 kg/litre |
Estimate the green weight of krill caught (using equation) | |
Flow scale | |
Prior to fishing | Ensure that the flow scale is measuring whole krill (i.e. prior to processing) |
Every haul329 | Obtain a sample from the flow scale and: |
measure the mass of krill and water combined | |
estimate the flow scale mass correction derived from the drained mass of krill | |
Estimate the green weight of krill caught (using equation) | |
Plate tray | |
Prior to fishing | Measure the mass of the tray (if trays vary in design, then measure the mass of each type; precision ±0,1 kg) |
Every haul | Measure the mass of krill and tray combined (precision ± 0,1 kg) |
Count the number of trays used (if trays vary in design, then count the number of trays of each type) | |
Estimate the green weight of krill caught (using equation) | |
Meal conversion | |
Every month328 | Estimate the meal to whole krill conversion by processing 1 000 to 5 000 kg (drained mass) of whole krill |
Every haul | Measure the mass of meal produced |
Estimate the green weight of krill caught (using equation) | |
Codend volume | |
At the start of fishing | Measure the width and height of the codend (precision ± 0,1 m) |
Every month328 | Estimate the volume-to-mass conversion derived from the drained mass of krill in a known volume (e.g. 10 litres) taken from the codend |
Every haul | Measure the length of codend containing krill (precision ± 0,1 m) |
Estimate the green weight of krill caught (using equation) | |
A new period will commence when the vessel moves to a new subarea or division. | |
Individual haul when using a conventional trawl, or integrated over a six-hour period when using the continuous fishing system. | |
