Sword-fish
capture monitoring
For
several years Necton has been dealing with
a research project aimed
at establishing the real impact of this
kind of activity has on the species fished.
By using this peculiar and enchanting method
fishermen not only capture the sword-fish,
but also other species, often disregarded,
but also important for the economy and for
the sea eco-system. Among the fished species,
besides the sword-fish, are the tuna-fish
(Tunnus Thynnus), the spearfish (Tetrapturus
belone), the lampuga (Coryphena hippurus),
the sunfish
(Mola mola),and different species
of selaci such as: the blue
shark (Prionace glauca); the
giant devilray (Mobula mobular); the
mako (Isurus oxirynchus, photo), the basking
shark (Cethorinus maximus)and, in the past,
several specimen of the white
shark (Carcharodon carcharias).The
reserch made by Necton consists in collecting
as many data as possible concerning the
sea-weather conditions, the number, the
size, the sex, the stomach content, the
presence of parasites, the capture frequence
of all the captured specie, etc. For this
reason, from the beginning of May to the
end of August, the Necton researchers are
embarked on the feluche.
