Codigo de Conducta para la Pesca Responsable

La pesca, incluida la acuicultura, constituye una fuente vital de alimentos, empleo, recreación, comercio y bienestar económico para las poblaciones de todo el mundo, tanto para las generaciones presentes como para las futuras y, por lo tanto, debería llevarse a cabo de forma responsable. En el presente Código se establecen principios y normas internacionales para la aplicación de prácticas responsables con miras a asegurar la conservación, la gestión y el desarrollo eficaces de los recursos acuáticos vivos, con el debido respeto del ecosistema y de la biodiversidad. El Código reconoce la importancia nutricional, económica, social, cultural y ambiental de la pesca y los intereses de todos aquellos que se relacionan con el sector pesquero. El Código toma en cuenta las características biológicas de los recursos y su medio ambiente y los intereses de los consumidores y otros usuarios. Se insta a los Estados y a todos los involucrados en la actividad pesquera para que apliquen el Código de manera effectiva. (PDF contains 53 pages)

Quantitative data on the feeding of Cyclops strenuus Fischer and Cyclops viridis Jurine. [Translation from: Trudy saratov.Otd.vses.nauchno-issled.Inst.ozer.rech.ryb.Khoz. 1, 163-176, 1951.]

Cyclopids, exactly in the same way as daphnids, significant component in the nutrition of plankton-f and the young of the majority of fishes. It is established that the food spectrum of cyclopids is extremely broad: daphnids, planarians, Copepodite stages of copepods (cannibalism), rotifers, protists, bacteria, phytoplankton and so on. It is clear that the problem of studying these or other components of feeding in the general food spectrum can be definitely resolved only after obtaining exact quantitative data on the feeding of cyclopids. This article attempts to fill the gap in the study of the quantitative side of the feeding of cyclopias; in it is investigated the size of the 24-hour ration of cyclopids feeding on protists, the dependence of the ration on some factors of the external medium, and the difference of 24-hour consumption per unit weight of tody with two species of cyclopids (Cyclops strenuus and Cyclops viridis).

Some aspects of the ecology of the limnoplankton, with special reference to the phytoplankton. [Translation from: Svensk Botanisk Tidskrift 13(2) 129-163, 1919.]

This paper tries to develop more generally some fundamental bases for the ecological study of freshwater plankton. A special attention is given to the phytoplankton associations which can be separated out and made into groups according to their dependence upon changing environments. Plankton formations in different types of water bodies (ponds, lakes and rivers) are studied.

Tropical forest history of the Ecuadorian Andes over the last 34,000 years: preliminary results from pollen and oxygen isotope analyses of Trident 163-13 from the eastern equatorial Pacific [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Pollen from the upper 2.75 m of a core taken 200 km west of the Golfo de Guayaquil, Ecuador (Trident 163-13, 3° S, 84° W, 3,000 m water depth) documents changes in Andean vegetation and climate of the Cordillera Occidental for ~17,000 years before and after the last glacial maximum.
