Best management practices minimize impacts of aquaculture effluents
Both aquaculture effluents and production costs can be reduced by using stock-specific feeds applied in smaller quantities several times a day.
Improving the osmoregulatory capacity of Pacific white shrimp grown in low salinity
Study shows it is possible to improve shrimp production in low-salinity waters by correcting magnesium and potassium deficiencies.
Low-salinity, inland shrimp culture in Brazil and Ecuador
Some producers take advantage of shrimp's ability to tolerate a broad range of salinity variations by rearing in low-salinity waters.
Zero exchange, aerobic, heterotrophic systems: key considerations
Most environmental concerns about aquaculture practices can be addressed effectively by zero exchange, aerobic, heterotrophic culture systems.
Efficacy of probiotics in grow-out systems
An aquaculture probiotic is a bacterial supplement to manipulate microbial communities in the water and to improve growth and survival of the cultured species.
Waste in aquaculture: Part 1
A review of various aspects of waste production from aquaculture, their sources and components, and methods of management for different culture systems.
Point: There are no essential ingredients in aquaculture feeds
Kevin Fitzsimmons, leader of the F3 (fish-free feed) Challenge, says aquaculture may currently depend on fishmeal and fish oil, but farmed fish do not.
How automatic shrimp feeders impact water and soil quality of grow-out ponds in Ecuador
Authors attempt to environmentally assess feeding areas of large shrimp ponds with acoustic feeders, a key step to improving production efficiency.
Cómo los alimentadores automáticos de camarones impactan la calidad del agua y el suelo de los estanques de engorde en Ecuador
Los autores intentan evaluar ambientalmente las áreas de alimentación de los grandes estanques de camarones con comederos acústicos, un paso clave para mejorar la eficiencia de la producción.
A circular economy approach to transform the future of marine aquaculture
Marine microalgae-based aquaculture has the potential to provide greater than 100 percent of global protein demand by 2050.
Un enfoque de economía circular para transformar el futuro de la acuacultura marina
La acuacultura basada en microalgas marinas tiene el potencial de proporcionar más del 100 por ciento de la demanda mundial de proteínas para 2050.
Prueba de caliza agrícola en estanques acuícolas
Este estudio de piedra caliza agrícola de cinco diferentes canteras estadounidenses determinó que las muestras tenían composiciones químicas comparables, pero solubilidades algo diferentes en agua. Este procedimiento podría ser útil para lograr mejores resultados cuando estos productos se usan en el encalado de estanques acuícolas.
Study identifies maximum holding times for water samples
Although pond water samples collected to measure water quality are often held on ice, the values of some common variables in the samples can vary over time.
Pangasius juveniles tolerate moderate salinity in test
The ability to culture pangasius in the low-salinity waters typical of coastal shrimp ponds in tidal zones would permit shrimp farmers to culture an additional species of economic importance and aid in diversifying the commercial aquaculture production of these areas.
Evaluating the effect of a commercial additive on growth and survival of larval Pacific white shrimp
The application of a commercial additive – combining immersion and feeding during larval rearing – resulted in improved growth and survival.
Evaluating hydrolysates as functional ingredients in Pacific white shrimp feeds
An evaluation of hydrolysates shows that cost-benefit, availability, quality and efficiency must be considered for feeding Pacific white shrimp.
Can a low-cost salt mixture replace sea salts for low-salinity shrimp farming?
Use of a low-cost salt mixture can reduce overall production costs for indoor, low-salinity shrimp farming systems.
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.
