Three isoform-specific antibodies, 6F against the α1-isoform of the avian sodium pump, HERED against the rat α2-isoform, and Ax2 against the rat α3-isoform, were used to detect the expression of Na+-K+-ATPase α-subunits in gills of a teleost, the tilapia ( Oreochromis mossambicus). Tilapia gill tissue showed positive reactions to antibodies specific for α1- and α3-isoforms. The results of immun...

In aquaculture, growth and sex are economically important traits. To accelerate genetic improvement in increasing growth in salt-tolerant tilapia, we conducted QTL mapping for growth traits and sex with an F2 family, including 522 offspring and two parents. We used 144 polymorphic microsatellites evenly covering the genome of tilapia to genotype the family. QTL analyses were carried out using i...

There are many species of tilapia, but only a few are widely cultured around the world. In the United States the most commonly cultured species of tilapia are the Nile (nilotica), Blue (aurea), Mozambique (mossambicus), Hornorum (hornorum), and hybrids such as the Taiwanese and Florida red. Choosing a species to culture depends largely on customer preference, legal status, growth rate and cold ...

Tank color impacts marine fish larval performance, as dark tanks appear to provide contrast that allows larvae to better visualize live and artificial prey. While tanks can be fabricated in any color, commercially available on–growing systems are generally black, green, or dark and light blue. Anecdotal information suggested that certain juvenile fish perform better in tanks with black sides an...

Key word: Growth promoter, mono-sex Tilapia, production, probiotic, FCR, SGR The present study was conducted in farmer’s ponds at field level of Muktagachha upazilla to find out the effect of growth promoter on growth performance and feed utilization of monosex Tilapia fish. Growth promoter was used in the experimental cultured farm. This growth enhancing aqua drugs was used in feeds of Tilapia...

MicroRNAs (miRNAs) are endogenous non-coding small RNAs which play important roles in the regulation of gene expression by cleaving or inhibiting the translation of target gene transcripts. Thereinto, some specific miRNAs show regulatory activities in gonad development via translational control. In order to further understand the role of miRNA-mediated posttranscriptional regulation in Nile til...

Streptococcus agalactiaeserotypes Ia and III were isolated from infected tilapia in cage and pond culture farms in Thailand during 2012 to 2014, in which pathogenicity analysis demonstrated that serotype III showed higher virulence than serotype Ia. Here, we report the draft genome sequencing of piscineS. agalactiaeserotypes Ia and III.

We proposed an approach to relate metal toxicity to the concentrations of arsenic (As) in specific target organs of tilapia Oreochromis mossambicus. The relationships among As exposure, uptake, accumulation, and toxicity of tilapia were investigated using kinetic and dynamic modeling. The biouptake rate of waterborne As through the gills of fish was dependent on exposure concentrations, in that...

This study evaluated the potential to orally deliver a previously developed Streptococcus iniae vaccine in tilapia using OraljectTM technology. This technology was developed to administer bioactive compounds to monogastric animals, and has been shown to be effective for delivery of a variety of antigens in numerous fish species. Two different formulations containing two doses of vaccine (four t...
