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.

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 ...

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.

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 ...

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 ...

Stock Assessment of the Peruvian Anchovy (Engraulis ringens) and Management of the Fishery
Journal of the Fisheries Research Board of Canada, 1973The upwelling of cool nutrient-rich water makes the area off Peru one of the most productivein the world. The first major use of this resource was the production of guano. In 1957 the fishery for anchoveta (Engraulis ringens) for reduction to meal and oil began on a significant scale.

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 (
