The cytological response of rainbow trout Oncorhynchus mykiss head kidney macrophages to ingested Mycobacterium spp. was examined in vitro. Mycobacterium marinum or Mycobacterium sp. TB267 isolated from snakehead fish Channa striata Bloch were opsonised with either fresh rainbow trout serum, serum which had been heat-inactivated, or rainbow trout antiserum against the extracellular products (EC...

in this study, the antimicrobial effect of sea cucumber extract (0.5, 1 and 2%) on the microbial population of rainbow trout fillets during refrigerated storage was examined. fillets were stored for 16 days and every 4 days microbial tests (including total bacterial load, pseudomonas, enterobacteriaceae and h2s producing bacteria) were performed on the samples. results showed that there was no ...

Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a pyridine herbicide frequently used to control invasive, noxious weeds in the northwestern United States. Clopyralid exhibits low acute toxicity to fish, including the rainbow trout (Oncorhynchus mykiss) and the threatened bull trout (Salvelinus confluentus). However, there are no published chronic toxicity data for clopyralid and fish tha...

the present study evaluated the effect of packaging (air, vacuum) with or without addition of sodium acetate (2% w/v) on shelf-life extension of rainbow trout (oncorhynchus mykiss) under refrigeration, for a period of 18 days. four different treatments were tested: cap: control air pack; saap: sodium acetate treated aerobic packaging; vp: vacuum packaging in the absence of sodium acetate; and s...

in order to investigate the effect of different temperature of anesthetic (clove tree) and recover (anesthetic-free water) solutions on recovery process, the anesthetic induction times and recovery times of 540 fingerlings of rainbow trout (oncorhynchus mykiss) weighing 3.2 ± 0.2 g in anesthesia/ recovery solutions with cross-combined of temperature of 5,11 and 17 °c as experimental treatments ...

The importance of rainbow trout (Onchorhynchus mykiss) in Iran aquaculture industry on one hand, and increasing the mortality of this fish due to outbreaks of infectious diseases, on the other hand, indicate the requirement for more profound understanding the rainbow trout immune system and access to laboratory tools for definitive diagnosis of its diseases. One of the most important defense me...

in this research green tea extract was prepared with water and then fishes in whole and gutted fish form was dipped in solutions of green tea extract (600 ppm) for 90 minutes and then were icing. during storage period (16 days), spoilage oxidation (pv, ffa, and tba), spoilage microbial indices (tvb-n, tvc, pvc) and sensory assessment with interval of 4 days were measured and compared with contr...

An important advance in aquatic ecotoxicology is the development and application of biomimetic sampling technology for hydrophobic contaminants. In this paper, accumulation kinetics of five organochlorinated pesticides, i.e. hexachlorobenzene, lindan, aldrin, heptachlor epoxide and 4,4'-DDT, by triolein-containing semipermeable membrane device (triolein-SPMD) and by fish (rainbow trout) were co...

Vitellogenin (VTG) induction has proved to be a valuable biomarker for assessing exposure to environmental estrogens in fish. The widespread use of VTG in this regard has lead to the need for standardized assays to quantify VTG, and monoclonal antibodies have the potential to help accomplish this. A VTG enzyme-linked immunosorbent assay (ELISA) was developed using a monoclonal antibody prepared...

Statistical review: Yes, but I do not feel adequately qualified to assess the statistics.
