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...

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...

This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...

Sox genes encode transcription factors that are involved in a variety of embryonic developmental pathways. Sox2 and Sox14 are located on the same chromosomal arm in several mammalian and bird species and on the basis of comparative maps were suggested as candidate genes for the major sex-determining locus on tilapia LG3. We have sequenced the sox2 and sox14 genes in four tilapia species and map...

Streptococcus agalactiae (Lancefield group B; GBS) is one of the major pathogens in fish production, especially in Nile tilapia (Oreochromis niloticus). The genomic characteristics of GBS isolated from fish must be more explored. Thus, we present here the genome of GBS S25, isolated from Nile tilapia from Brazil.

Streptococcus agalactiae (group B streptococcus [GBS]) is a pathogen that causes meningoencephalitis in Nile tilapia (Oreochromis niloticus). Here, we reported the complete genome sequence of S. agalactiae strain ZQ0910, which was isolated from the GIFT strain of Nile tilapia in Guangdong, China.
