Secretory proteins enter the secretory pathway by translocation across the membrane of the endoplasmic reticulum (ER) via a channel formed primarily by the Sec61 protein. Protein translocation is highly temperature dependent in mesophilic organisms. We asked whether the protein translocation machinery of organisms from extremely cold habitats was adapted to function at low temperature and found...

By living in a “world of water” fishes are exposed to major osmotic challenges that are opposite in nature in the freshwater and marine environments. In both cases, obligatory water fluxes primarily due to osmotic gradients across respiratory surfaces are threatening to the internal milieu and must be compensated by bulk flows of water in the opposite direction. While the ionoregulatory mechani...

the purpose of this experiment was to evaluate the effects of salinity on growth parameters and intestine morphology of the caspian white fish. experiment were used with four treatments include,(freshwater (0ppt), brackish water (5ppt), abrupt transition of fish to the salt water 10ppt: )the fish were transferred from fresh water to salt water immediately) and gradual transition of fish to the ...

background: diazinon is an organophosphorous pesticide which widely found in municipal, agricultural, and urban storm water discharges. the present study was conducted to achieve lethal concentration (lc50) and behavioral changes of rutilus rutilus caspius and hypophthal-micthys molitrix after exposure to lethal concentration of diazinon. methods: the experiment was carried out in static condit...

Ornamental fishes are among the most popular and fastest growing categories of pets in the United States (U.S.). The global scope and scale of the ornamental fish trade and growing popularity of pet fish in the U.S. are strong indicators of the myriad economic and social benefits the pet industry provides. Relatively little is known about the microbial communities associated with these ornament...

Modelling of fish swimming patterns has long been a challenge for the aquaculture community. In this proposed work, the modeling of fish swimming patterns and water condition such as pH, temperature and dissolved oxygen in fish tanks are analysed using network cameras and water sensors. An enhanced object tracking algorithm consisting of a combination of motion detection and condensation algori...

A ranavirus (RV) was isolated from Chinese giant salamanders (Andrias davidianus) in China in 2010 and provisionally designated Andrias davidianus ranavirus (ADRV). The complete genome sequence is 106,719 nucleotides long. Genomic sequence and phylogenetic analyses showed that ADRV has a high degree of conservation with other RVs.

Bacterial agents must be genotypically analyzed for vaccinations, effective control programs, and antimicrobial resistance genes that could transfer from aquaculture settings to terrestrial ecosystems and humans. Therefore, we investigated the prevalence, genotypic characterization, and antimicrobial resistance of Lactococcus garvieae for two years at aquaculture sites throughout Turkey. A tota...
