Such declines can be understood using three methods, in increasing level of mathematical difficulty: (1) an intuitive approach based on the inverse-square law of radiation applied to parasite trans...

Characterization of manures from fish cage farming in Chile.

This study aims to characterize salmonid manures and to determine their potential use in agricultural soils. Sampling was carried out below salmon and trout cages in farms located in lakes and in the sea in the South of Chile during 2002-2003. Manure was analyzed for macronutrients, micronutrients and heavy metals. Results showed a high variability between samples and differences between sea an...
