Fig. 16.2. Near bottom temperature (full line) and oxygen (broken line) concentrations
at 34m depth and species number and density of the soft bottom macrobenthic community
Demersal fisheries use trammel and drift nets as well as hook and line in
well-oxygenated nearshore waters, while trawl fishery is limited to some
areas off northern Peru (5-9°S), with Peruvian hake (Merluccius gayi
peruanus) representing 70% (56,000 tons in 1993,192,000 tons in 1996) of
the landings. Other common species include gurnard (Prionotus stephanophrys ), congrios ( Genypterus maculatus, Lepophidium negropinna ), flatfish (Paralichthys adspersus, Hippo glossina macrops), mullets (i.e., Mugil
cephal us, M. liza ), sea bass (Paralabrax humeral is), dogfish (Mustelus spp.),
