Also its have been developed specific diets in order to satisfy its nutritional requirements in early stages of larvae (Frias-Quintana et al., 2016), experimental grow-out of juveniles in concrete ponds and the flesh organoleptic evaluation (Jesus-Contreras, 2016) and finally a financial analysis in polyculture (Gonzalez et al., 2011).
Rabbitfish are also ideal candidates for polyculture systems as they are non-aggressive and feed mostly on filamentous algae and other vegetation.
Citing the findings of many studies and field trials conducted in Bangladesh with carps and small fish species in pond polyculture, the FAO report reveals the presence of the small, native and vitamin A-rich mola carplet significantly improves the nutritional quality of the total fish, without affecting the growth of carp fishes.
Its higher growth rate and compatibility with other major carps (Labeo rohita, Cirrhinus mirigala, Cyprinus carpio) specific surface feeding habit and consumer preference have increased its popularity in carp polyculture system among the fish farmers in India, Bangladesh, Myanmar, Pakistan and Thailand (Costa-Pierce, 2005).
Farmers are, therefore, advised to grow catfish either as monoculture or polyculture with other fish species.
About recycling: Corbett sees the preferablility of aluminum, better because of its close connection with the earth through bauxite, and the dangers of plastic, which recycles poorly, as evidenced by the fact that five of the seven recycling numbers stamped on plastics "are rarely or never able to be recycled." She agonizes over a local retailer who keeps the doors to his establishment open to welcome customers; his lack of energy consciousness "models this wasteful behavior for others." Even when it comes to maintaining the grass in her yard, she is conflicted; instead of following the lead of her neighbors with their neatly manicured lawns, Corbett cultivates a "Freedom Lawn" which "encourages a hardy polyculture where all kinds of plants grow."
fluminea is also widely used as a biofilter to improve water quality in polyculture (Buttner 1986, Chang et al.
Types of fish culture: In the study area, 90% culture ponds were found to be used for polyculture while 8% for monoculture and the rest 2% used for fry rearing purposes (Figure 1).
Lernaea susceptibility, infestation and its treatment in indigenous major and exotic Chinese carps under polyculture system.
In Brazil, although scarce studies performed in trout farming (Caramel et al., 2014; Moraes et al., 2015, 2016), in bullfrog farming (Borges et al., 2012; Mercante et al., 2014) and in polyculture system (tilapia and shrimps) (Araujo-Silva et al., 2014), showed that environmental indicators can be a useful tool for characterizing the impact, since it allows the comparison of different systems, methods of creation, evaluation of the effectiveness of management practices used in the production system, descriptions of general standards and as reference values (Boyd et al., 2007; Kimpara et al., 2010).
Polyculture of tuberoses (carrot, beet and radish) with broadleaves (arugula, lettuce and coriander) is a practice that has been used in vegetable crop production systems in the semi-arid Potiguar region.
