Podemos crecer un mejor camarón, y de mejores maneras
El reciente Simposio Centroamericano de Acuicultura en Choluteca, Honduras, reunió a más de 600 participantes para discutir temas de la industria y sus perspectivas. La atención se centró en enfermedades del camarón y sus impactos en la producción, así como en alternativas prácticas.
Characterizing the microbial community of farmed Nile tilapia in Colombia
Study characterizes the microbial community and dynamics of a continuous-flow competitive exclusion culture derived from gut microbiomes in Nile tilapia.
Use of copper sulfate in fish and shrimp ponds
Copper sulfate is a cost-effective algae control for aquaculture ponds but producers should consider alternative products or management practices.
Uso de sulfato de cobre en estanques de peces y camarones
El sulfato de cobre es un control de algas rentable para estanques acuícolas, pero los productores deberían considerar productos o prácticas de gestión alternativas.
Brazilian aquaculture: Constraints and challenges (Part 1)
The Brazilian aquaculture industry has been growing steadily during the last two decades. Despite facing a number of challenges it is looking at continued growth and a larger role in the export markets.
Brazilian aquaculture: Constraints and challenges (Part 2)
Brazil will have to deal with an adverse economic and political environment in the next few years. One should expect high value fish products like shrimp, tilapia, Chilean salmon and cod being replaced by more affordable seafood and alternative meats, as consumers keep losing purchasing power due to inflation, unemployment and monetary devaluation.
Acuacultura Brasileña: Limitaciones y desafíos (Parte 1)
La acuacultura ha experimentado su mayor crecimiento en la última década (con un promedio de 8 por ciento por año) en comparación con otras industrias animales, pero todavía está muy por detrás de la producción alcanzada por las industrias avícola, bovina y porcina.
Proper water circulation in aquaculture ponds critical
Promoting water circulation during the day time is an effective strategy to enrich pond water with oxygen produced by photosynthesis, and can significantly reduce the costs of night time supplemental aeration.
Reviewing the ‘near-magical’ properties of water
Understanding the hydrologic cycle, water’s unique physical properties and their behavior in aquaculture systems – phases, humidity, saturation, stratification, light reflection and refraction – is pertinent to properly manage water quality in production systems, according to world-renowned expert Dr. Claude Boyd.
Revisando las propiedades ‘casi mágicas’ del agua
La comprensión del ciclo hidrológico, las propiedades físicas únicas del agua y su comportamiento en sistemas acuícolas - fases, humedad, saturación, estratificación, reflexión de la luz y refracción- es pertinente para manejar adecuadamente la calidad del agua en los sistemas de producción, según el reconocido experto Dr. Claude Boyd.
The oft-overlooked water quality parameter: pH
Attention to pH, a numeric scale used to specify the acid or alkaline condition of an aqueous solution, is very important. Reducing biomass and feeding rates together with phytoplankton control and liming can often keep pH at desirable values.
Properties of common commercial fertilizers in aquaculture
Commercial nitrogen and phosphorus fertilizers are widely used in aquaculture production systems to stimulate phytoplankton growth and the food web that provides natural food organisms beneficial to stocked fish fry and shrimp postlarvae.
Propiedades de fertilizantes comerciales comunes en acuacultura
Los fertilizantes comerciales de nitrógeno y fósforo son ampliamente utilizados en los sistemas de producción acuícola para estimular el crecimiento del fitoplancton y la trama trófica que proporciona organismos alimenticios naturales beneficiosos para alevines y postlarvas de camarones.
Diets for pond-raised red claw crayfish
Red claw crayfish have numerous attributes that make the species a good choice for aquaculture, including flexibility in feeding that may allow expensive prepared diets to be supplemented or replaced by natural foods or forages.
Clove oil, eugenol effective anesthetics for silver catfish
Clove oil and eugenol have been recommended and used as anesthetics for several fish species. Moreover, these products have received the attention of researchers because of their chemo-preventive effects, as well as their anti-inflammatory and antioxidant properties.
Saturated fatty acids limit effects of fish oil replacement in cobia diets
In a study of juvenile cobia diets, results suggested that lipid sources with high levels of saturated fatty acids and low polyunsaturated fatty acids can replace a large percentage of fish oil in feeds if they are amended with DHA.
Carbon-nitrogen ratios in pond fertilization and biofloc systems
Prof. Claude Boyd on the importance of carbon-nitrogen ratios for pond fertilization and biofloc systems, and the relevance of precise carbohydrate inputs.
Current production, challenges and the future of shrimp farming
At the Guatemalan Aquaculture Symposium in Antigua, the focus was shrimp farming in the region: production, nutrition, health management and markets.
