Abstract
A study was conducted in earthen ponds in an integrated system (fish-cum-ducks), for 120 days. The tested water parameters (temperature, pH, dissolved oxygen, salinity and phytoplankton numbers) did not significantly influence by the experimental treatments. Yet, total number of zooplankton and most of its classifications was lower significantly in water of non-integrated ponds. The 3rd treatment (40 duck/pond and fish feeding rate of 5, 4, and 3% daily during 1st two months, 3rd month, and 4th month, respectively) was the best concerning the final fish body weight, body weight gain, final body length, average daily body weight gain, specific growth rate, total fish production, and super and 1st class fish production. The worst treatments were those not integrated with ducks.
