The Government has issued an order in Dirio da Repblica authorizing purse seine vessels to catch accessory species
in a percentage higher than 20% allowed by law.
In this study, catches from both target and accessory species
tended to be higher in the net without TED.
and only an accessory species
Cantareus apertus and one accidental species Cernuella virgata are met in this station with occurrence rate of about 30.97%; Rumina decollatta is the most abundant species with a density of 127.5 per 100 [m.sup.2].
The accessory species
of this study were mostly members of the Ophiderinae, whereas in Rio Grande do Sul they were distributed among all subfamilies.
W = constant species; Y = accessory species
; z = accidental species; -- the species was not collected.
2002): constant species (X)= present in more than 50% of collections; accessory species
(Y)= present in 25% to 50% of collections and accidental species (Z)= present in less than 25% of collections.
In general it must be said that accessory species
are quite rare in the Alabashka pegmatites, in comparison with other well-known pegmatite districts of the world.
Slugs are accessory species
in all sites (Table 8).
These months presented similarities in biodiversity and in the frequency of constant and accessory species
. Further, on both months, the reservoir presented a great water volume, albeit not overflowing (Figure 2).

for this plant, while being a very frequent and constant species for C.
