Abstract

The scientific community has awakened for the fact that if the fishing grounds are not well studied and preserved in a

few years some of them, if not most, will be depleted and the social and economical factors involved in that are

enormous. So, in the last years several techniques highly specific (DNA based techniques) have arisen to help solving

the problems involved in managing great quantity of individuals which are, normally, in constant movement and

especially because they are not bound to country borders. In this work four of these techniques (Allozymes, RFLP,

SSCP and Microsatellites) were used in four species (

Merluccius merluccius

(hake

), Aphnopus carbo

(black

scabbardfish)

, Trachurus trachurus

(horse mackerel)

and

Sardina pilchadurs

(sardine

)

) which are economically very

important, not only for Portugal, but for several other countries.

The objective of this work, besides the population study of this species, was also to have a direct comparison between

the techniques.

The results obtained were very interesting because in almost all studies population subdivision was found,

the

exception was

S. pilchardus

.
