“…Recently, encouraged by the benefits of biofloc technology used in shrimp farming, researchers have also demonstrated production feasibility and improvement in the health status of silver catfish using this system (Poli et al . ). Closed systems and low water renewal are promising in aquaculture, and this type of technology could boost South American catfish production.…”

The South American continent is known for its high production and exports in fisheries and aquaculture, but has not reached its full potential in fish farming. The latest data on fish production in Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Uruguay and Venezuela were explored in this review. Aspects of biology, production, market and health of the species most produced in South America are described in detail. These species include the round fish (Colossoma spp., Piaractus spp. and hybrids) and catfish (Pseudoplatystoma spp. and hybrids), in addition to the promising pirarucu Arapaima gigas, yellowtail tetra Astyanax altiparanae and silver catfish Rhamdia quelen. Among the countries mentioned, Chile and Brazil are two of the largest intensive fish producers in the world. Chile relies primarily on marine fish, whereas Brazil is prominent for continental production. Special emphasis is given to the black pacu Colossoma macropomum because it is a commonly farmed fish in South American countries and offers several desirable productive characteristics (domesticated, omnivorous and easy to reproduce). Furthermore, this fish has the greatest potential to compete economically with tilapia production in South America. The production of native fish is currently overtaking the production of exotic species in some countries, which is considered a milestone for South American aquaculture. Regarding diseases, the main pathogens are similar to those observed throughout the world, such as Ichthyophthirius multifiliis, different species of monogeneans and trichodinids, and the bacteria Aeromonas hydrophila. Local pathogens, such as the parasites Perulernaea gamitanae and Goezia spinulosa, are also concerning.

“…The final body weight, specific growth rate and fish yield were higher (p < 0.05) in the C: N ratio adjusted tanks. The superior fish performance observed in the C: N ratio adusted tanks may be explained by their better water quality (less TAN and nitrite) and greater availability of natural food (bioflocs) to fish (Correia et al, 2014;Ekasari et al, 2015;Poli, Schveitzer, & Nuñer, 2015).…”

ABSTRACT. The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m -3 ), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: 'underwater structure' (absence and presence) and 'adjustment of the C: N ratio of water' (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.Keywords: aquaculture, Oreochromis, limnoculture, limnology.Integração dos sistemas perifíton e bioflocos no cultivo intensivo de juvenis de tilápia do Nilo RESUMO. O presente trabalho teve por objetivo determinar os efeitos da integração do sistema baseado em substrato (perifíton) com o sistema baseado no ajuste da relação C: N da água (bioflocos), no cultivo intensivo de juvenis de tilápia do Nilo (1,56 ± 0,07 g; 72 peixes m -3 ), sobre variáveis de qualidade de água, desempenho zootécnico e qualidade de efluentes, após 10 semanas. O delineamento experimental utilizado foi em blocos ao acaso, em arranjo fatorial 2 x 2, com quatro tratamentos e cinco repetições cada. Os fatores em teste foram os seguintes 'estruturas submersas' (ausência e presença) e 'ajuste da relação C: N da água' (não e sim). Os resultados de peso corporal final, taxa de crescimento específico e produtividade de peixe foram maiores (p < 0,05) nos tanques nos quais se fez o ajuste da relação C: N da água, quando comparado aos tanques sem esse ajuste. A presença das estruturas submersas nos tanques não afetou de modo significativo essas mesmas variáveis. Concluiu-se que o sistema de cultivo de peixe baseado em substrato (perifíton) não é indicado para cultivos intensivos de juvenis de tilápia do Nilo, nos quais há grande entrada de alimento artificial nos tanques de cultivo.

“…La capacidad de controlar el tipo de carbono y la relación C:N, por la formulación del alimento, eliminación o adición de sólidos orgánicos de carbono permite a los técnicos y productores acuícolas definir qué tipo de vía se vuelve dominante en sus sistemas de producción, en este sentido las relaciones C: N han variado entre autores reportando tasas > 10:1 , 12 -13:1 (Schneider et al, 2006); 15:1 (Monroy, 2013), 20:1 (Poli et al, 2015;Ekasari, 2014;Emerenciano, 2012;Emerenciano et al, 2012;Craig et al, 2012;Avnimelech, 2009;De Shryver 2008;Avnimelech, 1999).…”

“…Diferentes tipos de sólidos existen en un tanque con biofloc, los más comunes y fáciles de determinar y con los cuales se puede administrar el cultivo son los sólidos sedimentables (SS), otros son los só-lidos suspendidos totales (SST) y los sólidos suspendidos volátiles (SSV) (Avnimelech, 2009), así como el índice volumétrico de sólidos (SS x 1000 / SST) (Pasco, 2015).100 ml/L de SS en cultivo de tilapia es a juicio de Avnimelech, 2009, un indicativo de buena calidad del biofloc. Para Rhamdia quelen los mejores resultados en cuanto a sobrevivencia y crecimiento de poslarvas y alevinos se consiguieron en concentración de SST de 200 mg/L (Poli et al, 2015), en tanto que para Ictalurus punctatus, los mejores resultados de su cultivo se encuentran en 790 mg/L (Green, 2015). Teniendo en cuenta la práctica de adición a los cultivos de hidratos de carbono y cal hidratada y que estos en conjunto con las raciones aumentan la concentración de SST, es necesario regularlos y controlarlos, con sedimentadores, por ejemplo como lo plantea Ray et al, (2010).…”

Fundamentos de la tecnología biofloc (BFT). Una alternativa para la piscicultura en Colombia. Una revisión 77 ARTÍCULO DE REVISIÓN/REVIEW ARTICLE Fundamentos de la tecnología biofloc (BFT).Una alternativa para la piscicultura en Colombia. Una revisión Fundamentals of bioflocs technology (BFT).An alternative for fish farming in Colombia. A review. Fundamentos da bioflocos tecnologia (BFT ResumenLos sistemas convencionales de producción piscícola en Colombia empiezan a descender principalmente por la necesidad de grandes cantidades de agua cada vez más escasa, aumento de la contaminación de los afluentes de descargue, aumento del costo de los alimentos con gran desperdicio de los mismos y otros factores ambientales adversos como sequías en grandes áreas del territorio e irregulares volúmenes de producción por unidad de área o volumen. Por lo anterior la búsqueda de nuevas posibilidades de producción piscícola que sean amigables con el ambiente, incluyentes socialmente y rentables son cada vez más apremiantes. Una de las alternativas que empiezan a cautivar el interés de los piscicultores es el sistema de producción súper-intensiva con tecnología biofloc (BFT), la cual se sustenta en aprovechar la acumulación de residuos de los alimentos, materia orgánica y compuestos inorgánicos tóxicos a través de microorganismos presentes en los medios acuáticos, dando condiciones de dominancia a comunidades autótrofas y heterótrofas, resolviendo sustancialmente los problemas de saturación de nutrientes a partir de su reciclaje, en este sentido el objetivo de la presente revisión es presentar los fundamentos básicos de la BFT, como una alternativa de producción piscícola.Palabras clave: microorganismos, tecnología biofloc, piscicultura, nutrientes. AbstractConventional systems for fish production in Colombia begin to decline mainly due to the need for large quantities of increasingly scarce water, increasing pollution of the tributaries of discharge, increased cost of food with great waste of these and other factors adverse environmental and droughts in large areas of territory and different volumes of production per unit of area or volume. Therefore the searches for new potential for fish production is environmentally friendly, socially inclusive and profitable are becoming more pressing. One of the alternatives that are beginning to captivate the interest of farmers is the system of super intensive production bioflocs technology (BFT), which is based on the accumulation of waste
