Trophic dynamics of integrated rice and fish farming (IRF) systems were studied in irrigated rice plots stocked with common carp in Madagascar. Fish feeding behavior was assessed by analyzing stable carbon and nitrogen isotopes of fish and natural fe

Introduced rodents cause major effects on insular local flora and fauna. The presence of black rats (Rattus rattus) on Berlenga Island can be a threat to endemic and native species, especially for plants. Understanding the trophic position of black r

Trophic functioning of integrated rice agriculture to fish aquaculture in Madagascar: Insights from stable isotopes (δ13C & δ15N)

Flooded rice fields are ecosystems favorable to growth and production of aquatic organisms. They can even play a major role in feeding and nutrition of local communities, as source of self-recruiting species or supporting production of farmed fish in

Characterization of trophic niche partitioning between carp (Cyprinus carpio) and roach (Rutilus rutilus) in experimental polyculture ponds using carbon (δ13C) and nitrogen (δ15N) stable isotopes

Aquaculture, Elsevier, 2020, 522, ⟨10.1016/j.aquaculture.2020.735162⟩

In temperate fish polyculture, common carp (Cyprinus carpio) and roach (Rutilus rutilus) are two fish species commonly reared in the same ponds. In the natural environment, these two species are considered omnivorous and may compete for food sources.
