Effects of sumithion on growth and production of phytoplankton and zooplankton in aquaculture ponds
Sumithion is an organophosphorous pesticide widely used to control tiger bug in the fish larval rearing pond. The present study was aimed to investigate the effects of sumithion on plankton population abundance in aquaculture pond. The experiment was carried out with three treatments, i.e., ponds with no sumithion (T1), with 1.0 ppm sumithion (T2) and 2.0 ppm sumithion (T3). The water quality p...

متن کاملNitrogen transformations and balance in channel catfish ponds
A nitrogen (N) budget was developed for four, 400-m ponds stocked with 550 channel catfish (Ictalurus punctatus) fingerlings that were fed to satiation daily for 133 days with a ration containing 4.85% N. Feed accounted for 87.9% of the N input to ponds. Abundant N from ammonia (NH3), ammonium (NH4 ), and nitrate (NO3 ) and the high total N: total phosphorus ratio in pond waters prevented appre...
متن کاملImpact of Copper Sulfate on Plankton in Channel Catfish Nursery Ponds
Many fish culturists are interested in applying copper sulfate pentahydrate (CSP) to channel catfish, Ictalurus punctatus, nursery ponds as a prophylactic treatment for trematode infection and proliferative gill disease by killing snails and Dero sp., respectively, before stocking fry. However, copper is an algaecide and may adversely affect phytoplankton and zooplankton populations. We evaluat...
متن کاملPhytoplankton community and saprobic pollution index of warm water fishes ponds at East of Golestan Province, Gonbade Kavous city
The aim of this investigation is study of phytoplankton and saprobic index at warm water fishes ponds at East of Golestan province, Gonbade Kavous city. Phytoplankton and ciliate sampling was done monthly during one season culture from June to November 2011. Finally, 39 genuses from 7classes of phytoplankton's and 4 genuses from ciliate group were identified. Although, Between different classes...
