20.4.1 Parnaíba River Delta
Although small-scale industrial fishery is observed in the coastal adjacent areas,
fishing activities in the Parnaíba Delta itself are almost exclusively artisanal. The
mangrove uçá-crab and the common snook represent approximately 90% of total
fishing products (Farias et al. 2015) (Figs. 20.15b and 20.18a–d). The Delta fishery
production in 2006 was ~3500 tons (IBAMA 2008a). Finfishes represented 60% of
the total production, followed by shrimps (20%), crabs (17%) and oysters (3%)
(IBAMA 2008a). A compilation of total finfish production in the Delta from 1999
to 2006 shows that highwaterman catfish (Hypophthalamus edentatus), longnose
stingray ray (Dasyatis guttata) (Fig. 20.15a), mullets (Mugil spp.) (Fig. 20.7ab, )
and serra mackerel Scomberomorus brasiliensis (Fig. 20.15f) production exceeded
100 tons each during the period. While whitemouth croaker (Micropogonias furnieri) (Fig. 20.7e) and crucifix sea catfish (Sciades proops) productions exceeded
