Descomposición y acumulación de materia orgánica en estanques

Los estanques acuícolas acumulan materia orgánica de fertilizantes orgánicos, restos de micro-organismos producidos dentro del estanque, las heces de los animales criados y el alimento no-consumido. Claude E. Boyd, Ph.D., detalla las principales prácticas de gestión de la materia orgánica, y dice que frecuentemente la acumulación de materia orgánica no es tan grande como se creía.

Examining copper use in aquaculture

Copper is used for control of the blue-green algae responsible for off-flavors in aquaculture animals, treating diseases and parasites, and avoiding cage net fouling. Although copper is an essential nutrient for plants and animals, an excess can negatively affect the environment and human health.

Accuracy of custom water analyses varies

The reliability of trace element analyses reported by custom laboratories cannot be checked by simple techniques, and results may not always be accurate. One should check the reliability of major ion analyses by determining the charge balance and comparing the measured total ion concentration with the total ion concentration estimated from conductivity.

Appraising pond liners for shrimp culture

The use of plastic-lined ponds by shrimp farmers can significantly improve production efficiency, support more production cycles per year, and higher mechanical aeration rates and stocking densities. The capital cost of lining ponds can be very significant, so a thorough feasibility analysis is recommended when considering this production tool.
