are several ways by which turtle populations can be protected whilst
still allowing fishing to continue.
1) A trap door known as a Turtle Excluder Device, (TED), can be
installed into trawl nets at a low cost ($50-$400). These do not
impair the performance of the net but allow turtles to escape easily.
As turtles are so large and heavy, they increase the mass of the
catch considerably. This means that the fishing vessel has to trawl
a much heavier net through the water than it would want to, thus
wasting fuel. The implementation of TEDs save fuel and thus lead
to amore efficient fishing operation. The design of this net also
allows for the release of rocks and other junk gathered during the
Areas of sea with high populations of turtles at certain times of
the year can be declared "no fishing zones" at these times.
3) People who eat turtle meat (particularly the inhabitants of the
Ionic Apulia Coast in Italy) can be educated as to the damage their
demand for the meat is doing to the species.
4) Reduce "trawl times". It has been shown that the length
of time that a vessel has its nets or lines out is proportional
to turtle mortality rates. If a trawl does not exceed 60mins then
the mortality rate is approximately 0%, if it is increased to 200mins,
then the mortality rate increases to over 50% (HENWOOD and STUNTZ,
