A 102-day feeding trial was conducted to evaluate the effects of four different fish patterns on carp pond water quality and antioxidant biomarkers [superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GPx), reductase (GR), S-transferase (GST) Thiol groups (SH)], protein content biomass midge Chironomus plumosus. Farmed were fed two commercial diets: Soprofish 25/7 Standard (cont...

Short mobile elements are present in different recombined forms as interspersed GC-rich islands between AT rich centromeric 155 bp tandem repeats in the dipteran Chironomus pallidivittatus . The basic element is 80 bp long, has a pronounced invert repeat structure and contains a 17 bp segment similar to the CENP-B box in mammals. The element inserts into a specific site of the 155 bp repeat in ...

Regulatory mutants in the hemoglobin system of Chironomus larvae can be detected by shifts in the relative quantity of specific components among the 10-12 mixed monomers. One such mutant, at or near a hemoglobin structural locus in the right tip of chromosome 3, greatly increases the quantity of that minor hemoglobin and greatly diminishes the quantity of the hemoglobin normally most abundant. ...
