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 ...

The accumulation of bacteria in Brachionus plicatilis and Artemia franciscana during a Ž . short-term incubation was quantified using immunocolony blot ICB and an enzyme-linked Ž . immunosorbent assay ELISA . Four bacterial strains, isolated from turbot and halibut, were Ž 7 y1. grazed effectively by both species when given at high concentrations G5=10 bacteria ml . B. plicatilis accumulated 21...

Diet has profound effects on animal longevity and manipulation of nutrient sensing pathways is one of the primary interventions capable of lifespan extension. This often is done through caloric restriction (CR) and a variety of CR mimics have been identified that produce life extending effects without adhering to the rigorous CR dietary regimen. Glycerol is a dietary supplement capable mimickin...

1. In this study we address how growth rate in consumers may be regulated by nitrogen (N)and phosphorus (P)limitation of ribonucleic acid (RNA), using the rotifer Brachionus calyciflorus as the model organism. 2. Growth rate, RNA and weight-specific concentrations of carbon (C), N and P were analyzed in B. calyciflorus fed algae with different C : N, C : P and N : P ratios. 3. Growth rate corre...

BACKGROUND Rotifers are among the most common non-arthropod animals and are the most experimentally tractable members of the basal assemblage of metazoan phyla known as Gnathifera. The monogonont rotifer Brachionus plicatilis is a developing model system for ecotoxicology, aquatic ecology, cryptic speciation, and the evolution of sex, and is an important food source for finfish aquaculture. How...

This study aims to enlist Rotatoria in the Anzali wetland (southwest Caspian Sea), a wetland which is listed as an international wetland in Ramsar convention (1975) and is an important ecosystem for spawning and early rearing of larvae of anadromous fishes. Samples of rotifers were collected in three regions of the Anzali wetland between  June 2015 and May 2016. A total of 29 genera of rotifers...
