Net diagram(s): …
For each net used, or any change in net configuration, refer to the relevant net diagram in the CCAMLR fishing gear library if available (www.ccamlr.org/node/74407), or submit a detailed diagram and description to the forthcoming meeting of WG-EMM. Net diagrams must include:
Length and width of each trawl panel (in sufficient detail to allow calculation of the angle of each panel with respect to water flow.)
Mesh size (inside measurement of stretched mesh based on the procedure in Conservation Measure 22-01), shape (e.g. diamond shape) and material (e.g. polypropylene).
Mesh construction (e.g. knotted, fused).
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.
Device diagram(s): …
For each type of device used, or any change in device configuration, refer to the relevant diagram in the CCAMLR fishing gear library if available (www.ccamlr.org/node/74407), or submit a detailed diagram and description to the forthcoming meeting of WG-EMM.

| 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 montha | 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 metera | |
| Prior to fishing | Ensure that the flow meter is measuring whole krill (i.e. prior to processing) |
| More than once per montha | 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 haulb | 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 meterb | |
| 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 weeka | 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 haulb | 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 |
