is prohibited to use a chafing piece if a lifting strap is not attached to the
cod-end.
(2) It
is prohibited to use a chafing piece that is more than one metre long.
(3) A
chafing piece may only be attached in front of and behind each lifting strap.
(4) The
mesh size of a chafing piece must be at least equal to that of the cod-end.
(5) If
the circumference of a chafing piece is to be compared with the circumference
of a cod-end or strengthening bag they shall be compared when the chafing piece
and the cod-end or strengthening bag are each stretched with the same force.
47 Codline defined
(1) A
codline is a rope that makes it possible to close the
rear of a cod-end or of a strengthening bag.
(2) It
works either by means of a knot that can be easily loosened or by means of a
mechanical device.
48 Regulation
of codlines
(1) A
codline must be attached at a distance that is not
more than one metre from the rear meshes of the cod-end, which may be folded
back into the cod-end.
(2) If
a torquette is attached the codline
must be passed through the rearmost meshes of the cod-end.
(3) More
than one codline may be used on a trawl.
(4) A
codline must not enclose a bottom-side chafer or
top-side chafer.
49 Lifting

Measurement algorithm
To allow for creep in a
stretched mesh –
1. extend
the movable jaw into the mesh at a constant speed of
300 ± 30 mm/min (*), until the measurement force is
reached;
2. stop
the motor and wait for 1 second;
3. if
the force drops below 80% of the pre-set measurement force, extend the movable
jaw into the mesh until the measurement force is reached once more.

Schedule 9[40]
(Regulation 28)
Technical specification of
the twine thickness gauge
Gauges for assessing the
thickness of twine must –
(a) be made of durable, non-corrosive material
able to withstand a harsh marine environment and must be manufactured in
accordance with the drawings shown in the figure below;
(b) have
edges around the circumference of each side of the circular hole for assessing
the thickness of the twine (the hole) rounded to avoid abrasion when the twine
is pulled through the hole to test legality;
(c) be
constructed with the nose of the pliers rounded to facilitate inserting the
jaws between double twines;
(d) have
jaws with parallel action that are sufficiently strong to prevent deformation
of the jaws during any reasonable use, bearing in mind that the jaws have to be
squeezed closed with manual force during every measurement;
(e) have
the inside faces of the jaws milled to leave a 0.5 mm gap for a distance
of 1 mm either side of the hole when the jaws are closed in order to avoid
single filaments of material protruding from braided or twisted construction
being trapped in the flat surfaces of the jaws on each side of the hole in
which the twine is seated;
(f) have,
when the jaws are closed, the diameter of the circular hole marked in
millimetres on one of the jaws, adjacent to the hole; the jaws are closed when
the surface of both internal sides of the jaws touch each other and are flush;
(g) have
a tolerance for the hole diameter of 0 + 0.1 mm;
(h) be
conveniently portable such that a set of 4 (4 mm, 5 mm,
6 mm, and 8 mm) gauges may be carried by a fishery officer during
vessel to vessel transfer at sea;
(i) if
gauges are of different sizes, be easily identifiable;
(j) be
easy to insert between double twine. After the gauge has been inserted into
position, it must be capable of easy operation with 1 hand;
(k) be
marked with the words “EC gauge”.

(Regulations 29 and 30)
Calibration and testing of
the mesh gauge
A. Verification
of length measurement
The verification of length
measurement must be performed by inserting the jaws of the gauge to be used
during the inspection, into slots of different lengths in the calibrated rigid
test plate. This can be done at any time.
Figure 1
Length of slots in mm
B. Verification
of force measurement
The verification of force
measurement must be performed by hanging calibrated weights on the fixed jaw
containing the load cell, with the gauge held vertical and secure. The weights
must have the following values: 10, 20, 50 and 125 N. The weights must
only be used under stable conditions.

illustrative purposes only)

Schedule 11[42]
(Regulations 33 and 35)
Preparation of the mesh
gauge
1. The
fishery officer must –
(a) select the appropriate size of jaw for the
meshes to be measured;
(b) ensure
that the jaws are clean;
(c) check
that the gauge completes the self-test satisfactorily;
(d) select
the measuring force to be applied as follows –
(i) for
mobile gear –
20 N for mesh sizes
< 35 mm,
50 N for mesh sizes
≥ 35 mm and < 55 mm,
125 N for mesh sizes
≥ 55 mm;
(ii) for
passive gear –
10 N for all mesh sizes;
(e) verify
the jaw type setting. The default setting is ‘Normal’. If small or
large jaws are used, the fishery officer must enter the menu and change the jaw
type setting accordingly.
2. When
the activities set out in paragraph 1 are completed the gauge is ready to
undertake mesh measurements.
Schedule 12[43]
(Regulations 33 and 34)
Operation of the mesh gauge
for inspection
When measuring the meshes
the fishery officer must –
(a) insert the jaws into the mesh opening with
the fixed jaw of the gauge against the knot, as shown in the figure below;
(b) activate
the gauge allowing the jaws to open until the movable jaw reaches the opposite
knot and stops when the set force is reached:
