Communal Fisheries Management in the Peruvian Amazon
Human Organization, 1997Community-level management of lake fisheries is becoming an increasingly viable alternative in many areas of Amazona. Population growth and increased commercial fishing have led to intense competition and conflict over fishery resources. Conservation can only be successful in these competitive environments when resource management is adapted to solving

Modelling change in the Peruvian-Chilean Eastern Pacific Fisheries
GeoJournal, 1993Time-series analyses of the Peruvian-Chilean Eastern Pacific Fisheries output are presented. The paper discusses how human action and adverse environmental conditions have affected regional productivity levels and fish stock. It is shown that overfishing during critical environmental periods is the likely cause for fluctuations in regional output and ...

Impact of El Niño events on pelagic fisheries in Peruvian waters
Deep Sea Research Part II: Topical Studies in Oceanography, 2004Abstract Using data from stock assesment surveys on pelagic resources during El Nino events of 1972/73, 1982/83, 1997/98, we analyze biological changes on pelagic ecosystems and pelagic fisheries during different stages of development of El Nino phenomenon: emergence, full, final and post-Nino.

Interactions Between Leatherback Turtles and Peruvian Artisanal Fisheries
Chelonian Conservation and Biology, 2007ABSTRACT From 1985 to 1999, data were gathered opportunistically on the bycatch of 33 leatherback turtles in coastal Peru, and from 2000 to 2003, a dockside observer program provided data on an additional 133 leatherbacks caught in the coastal gillnet and longline fisheries targeting mahi mahi, sharks, and rays.

Biology and fisheries of Peruvian hake (M. gayi peruanus)
1995The Humboldt Current ecosystem off western South America is a typical eastern boundary current upwelling system which is characterized by high levels of organic production. It is dominated by four pelagic schooling fish species: anchovy (Engraulis ringens), sardine (Sardinops sagax sagax), horse mackerel (Trachurus murphyi) and mackerel (Scomber ...

Quaternary Research, 2004
Understanding the influence of natural climatic variability on modern fisheries is complicated by over a century of industrial fishing. Archaeological data provide unique opportunities for assessing precolonial and preindustrial fisheries. Records show that anchoveta-vs sardine-dominated fisheries correlate with 20th-century climate change in the ...

Fisheries in upwelling regions — with special reference to peruvian waters
Geoforum, 1972Abstract The anchovy population that is the basis of the Peru fishery, the world's largest, is a phytoplankton feeding species, supported by an upwelling based ecosystem. The fish is very short-lived and grows rapidly — both criteria for high turnover rate — high yield fisheries.

Climatic Change, 2009
Peru experiences recurrent ENSO (El Nino Southern Oscillation) events during which the Peruvian bay scallop (Argopecten purpuratus) undergoes substantial changes in its stock size. In the North of the country strong warm ENSO events are synonymous with floods and river discharges that negatively affect scallop biomass, while in the South increased sea ...

Small cetacean captures in Peruvian artisanal fisheries: High despite protective legislation
Biological Conservation, 2010We detail the first direct, at sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline fisheries. A total of 253 small cetaceans were captured during 66 monitored fishing trips (Gillnet: 46 trips; Longline: 20 trips) from the port of Salaverry, northern Peru (8 o 14 0 S, 78 o 59 0 W) from March 2005 to July 2007.

Journal of Fish Biology
AbstractFrom December 2012 to June 2014, 796 Pacific guitarfish were caught in 183 fishing sets in northern Peru. Catch occurred in 86.3% of sets. Most individuals caught were mature with a bias toward males. The mean total length for females and males was 83.4 cm, and 91.1 cm, respectively. The capture per unit effort (CPUE) was 12.6 ± 3.4 guitarfish (
