Resistance to pathogens is important for the sustainability and profitability of food fish production. In immune-related genes, the lipopolysaccharide-binding protein (LBP) gene is an important mediator of the inflammatory reaction. We analyzed the cDNA and genomic structure of the LBP gene in tilapia. ...
The effects of aflatoxin B1 (AFB1) exposure and sodium selenite supplementation on cell apoptosis of jejunum in broilers were studied. A total of 240 one-day-old male AA broilers were randomly assigned four dietary treatments containing 0 mg/kg of AFB1 (control), 0.3 mg/kg AFB1 (AFB1), 0.4 mg/kg supplement ...
A method to mitigate or possibly eliminate reproduction in farmed fish is highly demanded. The existing approaches have certain applicative limitations. So far, no immunization strategies affecting gonadal development in juvenile animals have been developed. We hypothesized that autoimmune mechanisms, ...
The onset of exogenous feeding, when juveniles emerge from the gravel, is a critical event for salmonids where early emergence and large size provide a competitive advantage in the wild. Studying 131 farmed, hybrid and wild Norwegian Atlantic salmon families, originating from four wild populations and ...
Induced-swimming can improve the growth and feed conversion efficiency of finfish aquaculture species, such as salmonids and Seriola sp., but some species, such as Atlantic cod, show no or a negative productivity response to exercise. As a possible explanation for these species-specific differences, ...
Underwater Wireless Sensor Network (UWSN) environments have some very specific characteristics which introduce many challenges. Due to lack of sunlight as well as harsh conditions of underwater environment it is very difficult to change batteries and maintain power supply in underwater sensor nodes ...
Aquatic Vegetation serve variety of uses in a water eco system, some of which are vital to the overall health of the aquatic environment and also to add to the aesthetics of its surroundings and to provide a suitable habitat for aquaculture. Excess growth of these plants may indicate an imbalance and ...
Recently, there are many improvements in Internet of Things (IOT). Through the recombination and optimization, the real-world devices can provide their functionality as web services in IOT. However, it is very difficult to cost-effectively access to the Internet of Things due to the environmental changes. ...
This paper describes the necessity of developing ecological monitoring in the Baisha Lake of Nanji Wetland National Natural Reserve. Considering the geographical and environmental factors, the urgent need of ecological monitoring is discussed in the study area. According to the framework of wireless ...
Solid-state nitrate ion sensor or nitrate-ChemFET (N-ChemFET) based on polymeric membrane materials was fabricated and developed for the determination of nitrate ion in aqueous solution. The membrane materials used consisted of methyl-methacrylate (MMA) and tetrahydrofurfuryl-acrylate (THFA) as copolymers, ...
Most local freshwater prawn farmers in Thailand are currently relying their prawn production on a traditional farming approach, which requires highly-experienced farm manager, effort and time. By continuing with this inefficient approach, it is hard to improve the productivity, due to two main difficulties: ...
Transcriptome assembly techniques provide a valuable opportunity to learn more about non-model organisms. We present transcriptome assemblies for Pacific whiteleg shrimp (Litopenaeus vannamei), a species of great importance in global mariculture, that lacks solid transcriptome and genome references. ...
This article presents an automatic classification approach for assessing water quality based on fish liver histopathology. As fish liver is a good bioindicator for detecting water chemical pollution, the proposed approach utilizes fish liver microscopic images in order to detect water pollution. The ...
The case of fisheries management illustrates how the inherent structural instability of ecosystems can have deep-running policy implications. We contrast ten types of management plans to achieve maximum sustainable yields (MSY) from multiple stocks and compare their effectiveness based on a management ...
Background Infectious salmon anemia (ISA) is a serious disease of marine farmed Atlantic salmon, Salmo salar L. caused by ISA virus (ISAV). ISAV genomic segments 5 and 6 encode surface glycoproteins hemagglutinin-esterase (HE) and F protein important for the pathogenicity of ISAV. In this study, we ...
Background Insecticide-treated nets (ITNs) have proven instrumental in the successful reduction of malaria incidence in holoendemic regions during the past decade. As distribution of ITNs throughout sub-Saharan Africa (SSA) is being scaled up, maintaining maximal levels of coverage will be necessary ...
Key Concepts The two-dimensional Two-Tailed Comet assay (TT-comet) protocol is a valuable technique to differentiate between single-stranded (SSBs) and double-stranded DNA breaks (DSBs) on the same sperm cell. Protein lysis inherent with the TT-comet protocol accounts for differences in sperm protamine ...
Background It is common in public health and epidemiology that the outcome of interest is counts of events occurrence. Analysing these data using classical linear models is mostly inappropriate, even after transformation of outcome variables due to overdispersion. Zero-adjusted mixture count models ...
Background While significant focus has been given to net distribution, little is known about what is done with nets that leave a household, either to be used by others or when they are discarded. To better understand the magnitude of sharing LLIN between households and patterns of discarding LLIN, ...
Rising atmospheric CO2 is increasing the availability of dissolved CO2 in the ocean relative to HCO3−. Currently, many marine primary producers use HCO3− for photosynthesis, but this is energetically costly. Increasing passive CO2 uptake relative to HCO3− pathways could provide energy savings, leading ...
