The fish weir is one of the most traditional and productive fishing gear from the coast of Pará.
Its production reaches about 10% of fisheries production of Northeastern of Pará (Santos et al.,
2005). The fishing productivity depends on the type of the corral and as the place where it is
installed. To achieve this work, 12 fishing corrals were selected and classified according to the
type (heart, shoves and pipe), the place of installation ("edge/brink" or "out") and the type of
environment in which it is (riverbanks, the edge of the beach and sandbar/banks), were
georeferenced and had its fishing productivity accompanied during the period of harvest (June,
July and August) from 2012. In the community of San Juan de Ramos, were found roadside
corrals 3 of type heart, installed on the banks of the Paruipema River, and 3 corrals out of type
shoves, installed on sandbanks in the beaches mouse and of the sailor. In the community of Aê,
were monitored 6 classified as corrals of the edge, 3 of type heart and 3 of type pipe, and all
met installed in beach Ponta de Itaipu. 4.274 individuals were captured, distributed in 9 orders,
20 families and 43 species of fish. The order Perciformes was the one that presented the largest
number of families (10 families or 50% of the total), the largest number of species (19 or 44%)
and the largest number of individuals (3,190 or 75% of the total). Sciaenidae and Ariidae
families are the most abundant in the region both in number of species and individuals. The
Sciaenidae family was presented the highest number of individuals (2,855 or 67%), but had
fewer species (8 or 19%) that the family Ariidae, with 10 species or 23% of the total. Of the 43
species caught, the four most represented were: Macrodon ancylodon (51%), Arius couma
(9%), Cynoscion virescens (9%) and Mugil incilis (4%). The comparison of the catch between
the Stockyards and localities over the months of monitoring indicated that the total production
of corrals differed between the types of corrals associated with your location.
