Operational procedures

The biomass is automatically calculated based on choices you make in the

Calculation Interval

dialog; within a given time frame, a defined number of pings, or

a portion of the echogram view. The data is then taken from an echo area starting
immediately after the transmit pulse, and ending just over the detected depth. If
you have limited your vertical range (using the

Range

and

Start Range

settings),

the resulting area is used for the biomass calculation. If the seabed is clearly
defined with a unique bottom detection, the bottom echo will not be included in the
calculations. Therefore, if you switch the bottom detector off, the bottom echo will
be included in the calculation.

b

Bottom

The echogram is related to the detected bottom. Stop depth (lower echogram
boundary) and vertical range are manually selected by the

Start Depth

and

Range

buttons on the

Main

menu. The echogram is only drawn for pings having a

successful bottom detection.

The biomass calculation is made in the same way as for

Surface

echograms.

c

Pelagic

This echogram is nearly identical to the

Surface

echogram. However, the biomass is

calculated in a different manner.

The biomass calculations are not restricted by the bottom detection. This means that
the bottom echo will be included in calculations if it appears within the chosen range.

Example 9

Biomass calculation

If you are investigating a large school of pelagic fish, set the

Start Range

and

Range

to enclose the school. If the school is large enough, a

Surface

echogram may mistake it for bottom, and the biomass readings will
be wrong. The

Pelagic

echogram will however disregard the bottom

detection, and give a correct estimate of the biomass.

d

Trawl

This echogram covers the vertical opening of the trawl.

The echogram is only drawn when trawl position information is available.

The biomass calculation is made in the same way as for

Surface

echograms.

This procedure explains how to choose the echogram type you wish to see.
