the aim of this descriptive- correlational study was to assess trout farm fisheries owners' managerial skills and its relation with their farm yield. the statistical population consisted of all trout farm fisheries with official production license in mahneshan county (147 units) which 110 units as sample selected by multi-stage randomized sampling method based on cochran's sampling fo...

Aquaculture is a major source of invasive aquatic species, despite the fact that cultured organisms often have low genetic diversity and tend to be maladapted to survive in the wild. Yet, to what extent aquaculture escapees become established by means of high propagule pressure and multiple origins is not clear. We analysed the genetic diversity of 15 established populations and four farmed sto...

Trout farming, that represents the most important sector for aquaculture inland production in Italy, can cause negative effects on aquatic ecosystems. Recently, in the framework of Water Frame Directive 2000/60/EC and national law DL 152/2006, concerning the sustainable uses of water resources, multi-criteria approaches have been suggested to evaluate the impact of fish farming on aquatic ecosy...

This is the first report on the world that Pseudomonas psychrophila is a new etiological agent of disease in fish. A disease case occurred during the fall of 2017 in a rainbow trout farm in the north of Iran (Guilan province). Anorexia, lethargy and mortalities of 10% fish per week were observed in rainbow trout Oncorhynchus mykiss weighting 45-107g in three fresh water ponds of a farm on the n...

The direct effects of a Virginia trout farm on benthic macroinvertebrates were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring and from effluent both above and below a sedimentation basin. Onsite mesocosms were constructed to expose previously colonized artificial substrates to the same tr...

We announce the draft genome assembly of Lactococcus garvieae strain PAQ102015-99, a recently isolated strain from an outbreak of lactococcosis at a commercial trout farm in the northwestern United States. The draft genome comprises 14 contigs totaling 2,068,357 bp with an N50 of 496,618 bp and average G+C content of 38%.

We announce here the draft genome assembly of Flavobacterium columnare CSF-298-10, a strain isolated from an outbreak of columnaris disease at a commercial trout farm in Hagerman Valley, Idaho, USA. The complete genome consists of 13 contigs totaling 3,284,579 bp, with an average G+C content of 31.5% and 2,933 predicted coding genes.

We report here the complete genome sequence of Weissella ceti strain WS08, an emerging pathogen to farm-raised rainbow trout. The genome of strain WS08 is composed of a circular chromosome with 1,355,853 bp and a G+C content of 40.78%.
