Resumen

YANEZ R, Eleuterio; CATASTI V, Víctor; BARBIERI B, María Angela  y  BOHM S, Gabriela. Relationships between the small pelagic resources distribution and the sea surface temperatures recorded by NOAA satellites from Chile central zone. Investig. mar. [online]. 1996, vol.24, pp.107-122. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71781996002400009.

A survey study was conducted to assess the possibility of introducing the use of sea surface temperatures (SST), obtained from NOAA satellite data, for the small pelagic fisheries resources. Relationships between species yields and thermal gradients (TGR) were found significant. Jack mackerel (Trachurus murphyi) yields were largely related with a strong thermal gradient next to oceanic waters, while anchovy (Engraulis ringens) and common sardine (Clupea bentincki) yields were mainly associated to the development of coastal upwelling events. It is concluded that the use of SST-NOAA images can play an important role in fleet operations, particularly in the case ot the type of boats considered in this paper.

Palabras clave : fisheries; small pelagics; NOAA satellite, SST, TGR; central Chile.
