The purpose of this paper was to examine trade-offs between elimination and detoxification in rainbow trout and three common bivalve molluscs (clam, oyster, and scallop) exposed to cadmium (Cd), copper (Cu), and zinc (Zn) based on recent reported experimental data. We incorporated metal influx threshold with subcellular partitioning to estimate rate constants of detoxification (k(d)) and elimin...

Rainbow trout is economically the most important cultivated fish in Finland. In this study, new knowledge on the energy consumption, emissions and environmental impacts caused by the production of rainbow trout in Finland was generated. Methodologically the work was based on life cycle assessment (LCA) beginning from the extraction of raw materials and ending with the delivery of gutted fish to...

In this study the efficacy of bacterial culture, simple PCR and nested-PCR techniques for the detection of Yersinia ruckeri in tissues of naturally and experimentally infected rainbow trout (Oncorhynchus mykiss) fry was compared. In order to detect Y. ruckeri in naturally infected rainbow trout tissues, 30 fish suspected of enteric redmouth disease were randomly collected from 6 rainbow trout f...

At the present study, the distribution of Cd, Hg and Pb in water and their accumulation in fish species (silver carp, rainbow trout and shrimp) in three different farms. Totally 63 samples of three species and the water of their ponds were obtained during summer 2008 from Gilan, Mazandaran and ChabaharIran. The concentrations of three heavy metals in fish and shrimp flesh were measured by flame...

Experiments were conducted to assess the pathogenicity of 2 'atypical' Aerornonas salmon~cida strains solated from ulcerated flounders Platichthys flesus for this species, rainbow trout Oncorhynchus mykiss, roach Rutilus rutilus, and bleak Alburnus alburnus. The pathogenicity of the strains was evaluated by 3 challenge methods: intraperitonea] (i-p.) injection, subdermal (S d . ) injection, and...

We have identified ghrelin from the stomach of rainbow trout. Four isoforms of ghrelin peptide were isolated: the C-terminal amidated type of rainbow trout ghrelin (rt ghrelin) composed of 24 amino acids (GSSFLSPSQKPQVRQGKGKPPRV-amide) is a basic form; des-VRQ-rt ghrelin, which deleted three amino acids (V13R14Q15) from rt ghrelin; and further two types of rt ghrelin that retained the glycine r...

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...

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 ...
