Epilimnetic rotifer community responses to Bythotrephes longimanus invasion in Canadian Shield lakes
We studied whether the effects of Bythotrephes longimanus, a new predatory cladoceran zooplankton species to North America, can extend beyond the macrozooplankton to the rotifer community, which is known to be an important controller of the microbial loop. During summer 2003, 14 Canadian Shield lakes were sampled biweekly to evaluate the effect of Bythotrephes on epilimnetic rotifers. Rotifer d...
Growth rates of anchovy larvae, Engraulis mordax, reared for 19 days under constant environmental conditions on a diet of laboratory-cultured organisms, exceeded the growth rates of anchovies fed on a diet of wild plankton. The rotifer Brachionus plicatilis was found to be a nutritious food source when fed to the larvae in concentrations of 10 to 20/ml and in combination with the dinoflagellate...
Penelitian ini bertujuan untuk mengetahui pengaruh dosis ragi roti yang berbeda terhadap kepadatan rotifera (Brachionus plicatilis). dilakukan pada bulan Agustus 2021 di Laboratorium Perikanan Terpadu, Universitas Sulawesi Barat. Rotifera dikultur dengan pemberian pakan alami Nannochloropsis sp. sebanyak 41 ml penambahan berbagai roti. menggunakan Rancangan Acak Lengkap (RAL) 4 perlakuan dan 3 ...
Two euryhaline rotifers, the temperate species Brachionus plicatilis and tropical rotundiformis , were used to investigate effects of iron (FeSO 4 ·7H 2 O), an essential trace metal, on reproductive patterns lifetables, including metabolism lipid reactive oxygen (ROS). B. was more sensitive with regard sexual reproduction. While had no significant effect population growth at 0–48 μg/mL, it caus...
