Prevención de la alta toxicidad inducida por amoníaco en peces cultivados
Este estudio muestra que el cese de la alimentación puede no ser la mejor estrategia para controlar la toxicidad del amoníaco en peces en sistemas acuícolas que tienen picos de amoníaco.

Preventing high ammonia-induced toxicity in cultured fish
This study shows that cessation to feeding may not be the best strategy to manage ammonia toxicity to fish in aquaculture systems that have ammonia spikes.

Removing cyanobacteria and associated toxins in aquaculture ponds
Results of this study demonstrated that a commercial, granular, SCP-based algaecide corresponding to 2.5 mg/L H2O2 can be recommended as an eco-friendly strategy to effectively remove populations of the cyanobacterium Planktothrix sp. without compromising water quality or other plankton communities.

Aquamimicry: A revolutionary concept for shrimp farming
Aquamimicry simulates natural, estuarine production conditions by creating zooplankton blooms as supplemental nutrition to the cultured shrimp, and beneficial bacteria to maintain water quality. Better-quality shrimp can be produced at lower cost and in a more sustainable manner.

Dietary organic acids used as growth promoters, anti-microbials
A feeding trial measured growth, nutrient utilization and faecal/gut bacterial counts in triplicate groups of red hybrid tilapia (Oreochromis sp.). Study results show that dietary organic acids can potentially replace OTC as a growth promoter and anti-microbial in tilapia feeds.

Microencapsulated organic acids aid shrimp culture
A novel blend of organic acids (OAB) microencapsulated in a lipid matrix and supplemented in the diets of Litopenaeus vannamei enhanced their growth, phosphorus utilization, resistance to Vibrio harveyi and immunity. This may have implications as an eco-friendly prophylactic strategy.

Finishing diet strikes balance between feeding costs, tilapia fillet quality
In a study, tilapia were fed fish oil- or vegetable oil-based diets for five months, then switched to a fish oil finishing diet for three months. Growth and feeding efficiencies were not significantly compromised.
