Bacterioplankton is an important component of marine as well as fresh waters and accounts for a large fraction of the production of particulate matter in those ecosystems. The concept of bacteria as providers of essential nutrients in aquatic food webs has been raised most recently in relation to the utilization of bacteria as a food source in aquaculture food chains. This article represents a comprehensive review on the potential role of bacteria as a direct food source for aquaculture organisms. After studying shortly the analytical tools that can be applied to determine the uptake and assimilation of bacteria by higher trophic levels, it describes the bacterial loads that are found in closed and open aquaculture systems and elaborates on the composition of bacteria from a nutritional point of view. Next this study elaborates in more detail on the role of bacteria as food for the zooplankton groups used as live food in aquaculture hatcheries and for various groups of aquaculture target organisms, such as fish, crustaceans and especially bivalves. This includes an assessment of the specific uptake mechanisms of the different taxonomic groups of interest in relation to their efficiency to ingest bacteria. Finally, future research lines are suggested to elucidate the nutritional impact of the bacterial community in aquaculture systems and how to steer this in order to optimize the production.

“…En este trabajo, no hubo colonización de biofilm ya que los experimentos fueron realizados en condiciones controladas de laboratorio, con recambio de agua y sin exposición a la luz solar. Sin embargo, el exceso de red podría ser una desventaja para el cultivo a cielo abierto, ya que impediría el paso de luz (Parnes & Sagi, 2002), evitando que las comunidades de micro-organismos (biofilm) colonicen la red, mejoren la calidad de agua, y constituyan una fuente adicional de alimento para los juveniles (Viau et al, 2012).…”

“…Estas redes se unen entre sí semejando plantas acuáticas y ocupando la columna de agua. En esta superficie se desarrolla y crece el biofilm que los juveniles utilizan como alimento y mejora la calidad de agua (FAO, 2010;Viau et al, 2012). Las redes también proporcionan una mayor superficie, optimizando el espacio y protegiendo a los juveniles de otros de mayor tamaño (Villarreal & Peláez, 1999).…”

RESUMEN.Cherax quadricarinatus es una especie de elevado interés para la acuicultura y de gran tolerancia a las altas densidades, lo que la hace propicia para el cultivo en sistemas intensivos. El objetivo de este trabajo es determinar el diseño más adecuado de disposición espacial y la superficie de "red cebollera", usualmente utilizada como refugio de juveniles en cultivo, que permita disminuir la mortalidad y mejorar el crecimiento en condiciones de alta densidad. Se realizaron dos experimentos, poniéndose a prueba la disposición espacial (redes paralelas en posición vertical, horizontal y sin ordenamiento) y la superficie de red cebollera (0,612 m 2 , 1,224 m 2 y 1,836 m 2 ) en cultivo con alta densidad de juveniles (41,7 juveniles de 1 g m -2 ). A los 60 días se registró el número y peso de juveniles, y se calculó la mortalidad y biomasa. En el segundo experimento se contabilizó también la cantidad de quelas faltantes y juveniles con todos sus apéndices, para estimar las interacciones agonísticas. La mortalidad resultó menor en el tratamiento sin ordenamiento y en el tratamiento con menor superficie de redes (P < 0,05). Por cada m 2 de fondo, 2,55 m 2 de red cebollera colocada en forma aleatoria sería suficiente como refugio para una densidad alta de juveniles. La biomasa y las interacciones agonísticas fueron similares en todos los casos. Se determinó que la colocación de la red al azar es la disposición más adecuada y económica para los juveniles de C. quadricarinatus, y que su exceso podría perjudicar la supervivencia en cultivo.

Cherax quadricarinatus is an interesting species for aquaculture and is more tolerant to high densities than other species of commercially important crustaceans, making it suitable for intensive culture. The purpose of this study is to determine the most adequate spatial arrangement and area of onion bag mesh, commonly used as shelter in juvenile culture, to decrease mortality and improve growth under high-density conditions. Two experiments were conducted to evaluate the optimum onion bag mesh spatial distribution (parallel pieces of mesh arranged in a vertical and horizontal position, and mesh with a random arrangement), and area (0.612 m 2 , 1.224 m 2 and 1.836 m 2 ) under high-juvenile density conditions (41.7 one-gram juveniles per m 2 ). The weight and number of juveniles were recorded, and mortality and biomass were calculated at day 60. In the second experiment, the number of missing chelae and juveniles with all their walking legs were counted to estimate agonistic interactions. Mortality was lower in the treatment consisting in randomly arranged onion bag mesh and that with the smallest area. A mesh surface of 2.55 m 2 per m 2 of ground would be sufficient as shelter for juveniles stocked at high dens...

“…In marine shrimps production, the biofilm‐based culture systems with low or no water exchange showed improve water quality by recycling and recovering nutrients, and thus improving yield and reducing the use of water, and waste water discharge to the environment (Ballester, Wasielesky, Cavalli & Abreu ; Holl, Otoshi & Unabia ; Audelo‐Naranjo, Martínez‐Córdova, Gómez Jiménez & Voltolina ; Viau, Moreira Souza, Wasielesky, Abreu & Ballester ; among others). For freshwater crustacean culture, the effect of biofilm as an alternative and/or a complement food source in the culture has only been studied in the giant prawn Macrobrachium rosenbergii (Asaduzzaman, Wahab, Verdegem, Huque, Salam & Azim ; Uddin, Azim, Wahaba & Verdegem ; Hasan, Rahman, Hosen & Bashar ) and in the crayfish species Cherax destructor (Jones & Thanuthong ) and Cherax quadricarinatus (Viau, Ostera, Tolivia, Ballester, Abreu & Rodríguez ). However, no studies have been previously reported on the potential benefits of biofilm on the culture of freshwater shrimps.…”

The contribution of biofilm to water quality and as a food source for the culture of the freshwater shrimp Neocaridina heteropoda heteropoda was assessed in indoor aquaria using a zero water exchange system. Two successive phases were conducted to evaluate biofilm development on different substrates (polyethylene net: PN, plastic bottles: PET, agrovelo: AV) and the effect of biofilm to shrimps culture. The biofilm grown on all substrates helped to keep a good water quality by the uptake of nitrogen compounds and the production of high levels of dissolved oxygen associated to the proliferation of autotrophic microorganisms. High survival, reproduction and hatching of shrimps were achieved in all groups mainly associated with good water quality. Final biomass of the shrimps was significant higher for PN and AV groups; while specific growth rate and the levels of lipids of the shrimps yielded similar values for all treatments indicating that the three substrates allowed the growth of a biofilm that resulted in a healthy food source with similar nutritional value for shrimps. The results show that the production of N. heteropoda heteropoda could be successfully conducted by a biofilm‐based culture system with no water exchange, and thus contributing to a better water use. All materials tested were suitable substrates for biofilm growth, though AV and PET could reduce significantly production costs when compared to the PN. Moreover, by the recycling and reuse of waste materials (such as plastic bottles) could contribute to the development of a responsible, sustainable and environmentally friendly culture method.
