Health & Welfare
Effective implementation of biosecurity protocols in shrimp farming requires awareness, discipline and a commitment by farm owners to implement them. The authors take a close look at intensive nurseries and how to exclude pathogens, predators and competitors.
Responsibility
Aquaculture systems should be operated with attention to reducing the environmental waste load, which requires the use of high-quality feeds, prevention of overfeeding and maintenance of good water quality.
Aquafeeds
Manufactured aquafeeds, if improperly managed, can result in undesirable oxygen demand that can reduce dissolved oxygen levels and pollution through effluents, and stress cultured animals.
Responsibility
La producción mundial de la maricultura sostenible, desarrollada en una escala masiva y sostenible y utilizando sólo una pequeña fracción de las zonas oceánicas del mundo, podría eventualmente igualar la producción agrícola con base en tierra. La escala y consideraciones de derecho internacional requieren la participación de muchas partes interesadas, incluidos los gobiernos nacionales y las organizaciones internacionales.
Responsibility
Global, sustainable mariculture production, developed on a massive, sustainable scale and using just a small fraction of the world’s oceanic areas, could eventually match the output of land-based agriculture production. Scale and international law considerations require the involvement of many stakeholders, including national governments and international organizations.
Aquafeeds
Los sistemas de tecnología de biofloc bien diseñados y gestionados son una alternativa viable para la producción de diversas especies como la tilapia, para aumentar la eficiencia de los alimentos mediante la reducción de las necesidades de proteínas de alimentos acuícolas y para ayudar a reducir o eliminar las descargas de efluentes.
Aquafeeds
Well-designed and managed biofloc technology systems are a viable alternative for production of various species like tilapia, to increase feed efficiency by lowering aquafeed protein requirements and to help reduce or eliminate effluent discharges.
Responsibility
Both aquaculture effluents and production costs can be reduced by using stock-specific feeds applied in smaller quantities several times a day.
Responsibility
Drainage ditches on catfish farms function as settling basins that remove sedimentation and reduce nutrient loads from effluents before they enter receiving waters.
Responsibility
Phosphorus is one of the most scrutinized nutrients discharged by aquaculture systems, due to its potential eutrifying impact on receiving bodies of water.
