Shrimp pond preparation crucial for production, disease prevention
Preventing diseases is a major concern in shrimp farming. Pond preparation focuses on avoiding the carryover of disease organisms from one crop to the next.

How decomposition of organic matter impacts aquaculture ponds
Organic matter decomposition causes most of the water quality issues in aquaculture ponds. Bacterial populations are the primary organisms of decay in an aquaculture system, including its organic matter.

El parámetro de calidad del agua a menudo ignorado: pH
La atención al pH, una escala numérica usada para especificar la condición ácida o alcalina de una solución acuosa, es muy importante. La reducción de la biomasa y de las tasas de alimentación junto con el control del fitoplancton y el encalado pueden mantener el pH en valores deseables.

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.

Decomposition and accumulation of organic matter in ponds
Aquaculture ponds accumulate organic matter from organic fertilizer, remains of microorganisms produced within the pond, feces of the culture animals and uneaten feed. Claude E. Boyd, Ph.D., details the leading organic matter management practices, and says that the accumulation of organic matter is often not as great as believed.

Organic matter for pond fertilizer
Animal manures, grasses and other organic matter have been widely used as fertilizers in aquaculture ponds. The fertilizers decompose and release nutrients that promote the growth of phytoplankton and enhance the base of the food web.

Organic matter in pond bottom sediment
Organic matter – including fertilizers, unconsumed feed and feces of culture animals – settles to pond bottoms, often with a negative impact on water quality.
