“…These results suggest that common carp prefer benthic macroinvertebrates to zooplankton when plankton and benthic macroinvertebrates are provided together. This result is consistent with our earlier study (Rahman et al 2006) in rohu-common carp bi-culture ponds in which common carp principally ingested benthic macroinvertebrates in the absence of artificial feed. This preference for benthic macroinvertebrates most probably influenced common carp behavior as they spent more time near the bottom of the tanks for grazing and swimming in PB tanks than all other tanks.…”

“…Similarly, common carp might alter its food preference and behavior in response to changing food resources. Although there is some information about diet and feeding behavior of common carp (Adamek et al 2003;Rahman et al 2006Rahman et al , 2008a, their feeding niche in aquatic ecosystems under varying food resources is still not fully understood. Better information about how common carp changes its food selectivity and behavior with changing food resources is necessary to understand its ecology and to optimize feeding management.…”

We used customized fish tanks as model fish ponds to observe grazing, swimming, and conspecific social behavior of common carp (Cyprinus carpio) under variable food-resource conditions to assess alterations in feeding niche. Different food and feeding situations were created by using only pond water or pond water plus pond bottom sediment or pond water plus pond bottom sediment and artificial feeding. All tanks were fertilized twice, prior to stocking and 2 weeks later after starting the experiment to stimulate natural food production. Common carp preferred artificial feed over benthic macroinvertebrates, followed by zooplankton. Common carp did not prefer any group of phytoplankton in any treatment. Common carp was mainly benthic in habitat choice, feeding on benthic macroinvertebrates when only plankton and benthic macroinvertebrates were available in the system. In the absence of benthic macroinvertebrates, their feeding niche shifted from near the bottom of the tanks to the water column where they spent 85% of the total time and fed principally on zooplankton. Common carp readily switched to artificial feed when available, which led to better growth. Common carp preferred to graze individually. Behavioral observations of common carp in tanks yielded new information that assists our understanding of their ecological niche. This knowledge could be potentially used to further the development of common carp aquaculture.

“…Polyculture may produce expected results if fish with different feeding habits are stocked in proper ratio and combination (Halver, 1984). In Asian polyculture, a wide variety of fish species are cultured of which rohu (Labeo rohita), catla (Catla catla) and mrigal (Cirrhinus cirrhosus) are very popular (Rahman et al, 2006). The farmers prefer to stock Common carp as a bottom feeder instead of mrigal because common carp grows faster than mrigal and the overall production is higher when combined with rohu and catla in polyculture ponds (Wahab et al, 2002).…”

The shaded nature of ponds in Barisal region constrained the pond polyculture. The present study was conducted with such shaded ponds to evaluate the growth and production performance of different carp species including rohu (Labeo rohita), catla (Catla catla), mrigal (Cirrhinus cirrhosus) and common carp (Cyprinus carpio) in polyculture system. In this experiment, polyculture of carps at similar densities were conducted in two different types of shaded ponds selecting nine ponds at Dinar village in Charkawa Union of Barisal Sadar sub-district. Out of 9 ponds, 5 were heavily shaded ponds (HSP) and 4 were moderately shaded ponds (MSP) considered as T 1 and T 2 , respectively. The average area of HSP and MSP was 0.03±0.01 and 0.07±0.03 ha, respectively which were experimented for a period of l80 days from July to December 2013. Carps were stocked at the rate of 14820/ha with the ratio of rohu, catla, mrigal and common carp -2:1:2:1. Carps were fed with supplementary feed of the mixture of rice bran, wheat bran and mustard oilcake at the rate of 10% body weight for first 3 months and 5% body weight for last 3 months. The water quality parameters such as temperature, dissolved oxygen, pH, nitrite and ammonia were recorded. The highest weight gain was found in common carp (467.00±0.00 g) in T 1 and lowest weight gained in mrigal (172.46±26.80 g) in T 1 . Apart from common carp, the individual growth and production of other species was higher in MSP compared to HSP. The higher production was obtained in T 2 (2122.92±333.60 kg/ha/year) compared to T 1 (1547.79±132.94 kg/ha/year).

“…Common carp attained a higher yield than grass carp, maybe as a result of a greater consumption of balanced feed. Even though common carp prefers benthonic macro invertebrates, followed by zoo and phytoplankton, it changes its preference to balanced feed when available (Rahman et al, 2006). In the FS, the low condition factor of grass carp was related to the low quantity of feed consumed (grass and corn).…”

ABSTRACT. The carp polyculture production system is the most widely used system by small-scale fish farmers in southern Brazil (States of Paraná, Santa Catarina and Rio Grande do Sul). The aim of this study was to compare biotechnical and economic parameters between a farm system (FS) using farm inputs (chicken manure, maize and grass) and a commercial system (CS) using commercial inputs (triple super phosphate, ammonium nitrate and balanced food) feeding to apparent satiation. The experiment was carried out for 196 days in earthen ponds of 500 m 2 , with three replicates per system. The stocking density was 2,000 fish ha ) was observed. Production was significantly increased in the CS (76 kg 500 m -2 196 days -1 ) than in the FS (43 kg 500 m -2 196 days -1 ). Costs and revenues were higher in the CS and profits were similar in the two systems. Similar profits do not mean that CS is necessarily more convenient. Advantages and drawbacks for small-scale farmers considering labor, land and availability of money are discussed. Keywords: carp, polyculture, feed, water quality, cost-benefit, aquaculture, Brazil. Efectos de insumos de granja y comerciales en el desempeño del policultivo de carpas:ensayo participativo en una estación experimental en el campo RESUMEN. El policultivo de carpas es el sistema de producción de peces más utilizado por campesinos en el sur de Brasil (Estados de Paraná, Santa Catarina y Rio Grande do Sul). El objetivo de este trabajo fue comparar parámetros técnico-biológicos y económicos entre un sistema de granja (FS) utilizando insumos de la granja (gallinaza, maíz y pasto) y un sistema comercial (CS) utilizando insumos comerciales (súper fosfato triple, nitrato de amonio y alimento balanceado), alimentando hasta saciedad aparente. El experimento se efectuó en tierra durante 196 días en estanques de 500 m 2 , con tres réplicas por sistema. La densidad inicial de los peces fue de 2.000 ind ha ). Los costos e ingresos fueron mayores en el CS y las utilidades fueron similares en ambos sistemas. Utilidades similares no significan que el CS sea necesariamente más conveniente. Se discuten ventajas y desventajas para los campesinos considerando el trabajo, la tierra y la disponibilidad de dinero. Palabras clave: carpa, policultivo, alimento, calidad de agua, costo-beneficio, acuicultura, Brasil.
