چکیده

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 ulangan yaitu A sebagai kontrol yakni 0,0 mg/L, B 15,0 C 30,0 D 45,0 mg/L. Parameter diujikan rotifera. Analisis data ANOVA tingkat kepercayaan 95%. Hasil uji menunjukkan bahwa memberikan nyata (P<0,05) hari ke-3 sampai ke-5 pemeliharaan. Kepadatan tertinggi diperoleh pemeliharaan ke-4 mg/L 3.999.333 ind/L, kemudian ikuti (kontrol) 2.999.667 2.583.000 ind/L terendah 2.249.667 ind/L.

Induction of sexual reproduction in Brachionus plicatilis (Monogononta, Rotifera) by a density-dependent chemical cue

Induction of mixis (sexual reproduction) in rotifers of the genus Brachionus is believed to be triggered by a chemical that is released into the water and accumulates at high population densities. However, direct and conclusive evidence for this hypothesis is thus far lacking. In this study, two mass cultures of the rotifer Brachionus plicatilis were monitored as they grew from low to high popu...

Synergistic toxicity of Macondo crude oil and dispersant Corexit 9500A(®) to the Brachionus plicatilis species complex (Rotifera).

Using the marine rotifer Brachionus plicatilis acute toxicity tests, we estimated the toxicity of Corexit 9500A(®), propylene glycol, and Macondo oil. Ratios of 1:10, 1:50 and 1:130 for Corexit 9500A(®):Macondo oil mixture represent: maximum exposure concentrations, recommended ratios for deploying Corexit (1:10-1:50), 1:130 the actual dispersant:oil ratio used in the Deep Water Horizon spill. ...

Effect of periodical starvation on the life history of Brachionus plicatilis O.F. Müller (Rotifera): a possible strategy for population stability.

To estimate the changes in the life history of the rotifer Brachionus plicatilis O.F. Müller under starvation, we carried out an individual culture and determined the effects of periodical food deprivation on its asexual reproductive characteristics such as lifespan, reproductive period, age at first egg and offspring production, and lifetime fecundity (total number of offspring produced in her...
