Diet and Feeding Habits of Cyprinus carpio in Relation with Water Quality of Integrated Rice-Fish Farming Ecosystem

Abstract

This study describes the diets and feeding habits of Cyprinus carpio in integrated rice-fish farming system in the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, Central Bangladesh during May 1999 to August 1999. Percentage of frequency of occurrence and percentage in number methods were applied for the qualitative and quantitative estimation of plankton. The water quality parameters recorded during the study were within the suitable range for optimal fish growth and plankton populations were also abundant in the water of the rice plots. The phytoplankton population recorded from the gut contents of C. carpio was under 4 groups (viz., Chlorophyceae, Euglenophyceae, Cyanophyceae, Bacillariophyceae) and the zooplankton under 3 groups (viz., Rotifera, Cladocera, Copepoda). Bacillariophyceae and Chlorophyceae were the dominant phytoplankton group while Rotifera was the dominant zooplankton group in the gut contents of C. carpio. This study also revealed that, gut contents of C. carpio was composed of 48.47% phytoplankton and 51.53% zooplankton indicating omnivorous nature of the fish. The availability of plankton population in the rice plots and the food and feeding habits of C. carpio suggest that, this fish could be a vital candidate for integrated rice-fish aquaculture.

Distribution of perfluorinated compounds (PFASs) in the aquatic environment of the industrially polluted Vaal River, South Africa

“…Based on  15 N values, Baetidae showed the highest trophic position, followed by the fish species and C. nilotica. All studied fish species are omnivorous, which explains these results (Bloomer et al, 2007;Jimoh et al, 2011;Mondol et al, 2013). The high trophic position of Baetidae was not expected, as Palmer et al (1993) showed that the gut content of mayfly larvae consisted mainly of amorphous detritus.…”

Diet and feeding ecology of black-barred halfbeak Hemiramphus far (Forsskal, 1775) (Hemiramphidae) from Karachi coast of Pakistan

“…Moreover, data on the feeding habits of marine fishes, such as the predatory-prey relationship are very helpful in the ecosystem [9]. Information on stomach composition could be useful to fish farmers for multispecies fishery [10,11] and these are important requirements for the Ecopath model [12] used for elucidating aquatic ecosystem functioning and providing critical biological information for fisheries management [13,14].…”

Exploring Ecological Functions of Rice-Fish Integration in the Agricultural Landscape: A Review to Investigate Feasibility of Implementing Rice-Fish Integration in Sri Lanka

“…This phenomenon contributes positively to augmenting the availability of soil nutrients (Wan et al, 2010). Further, the behaviors of fish can induce soil aeration in rice fields (Mondol et al, 2013), while they also control pests and parasites in the rice fields. Certain fish species feed on insects, snails, and other pests that destroy rice plants, reducing the need for chemical pesticides (Frei and Becker, 2005).…”
