Pollution in aquatic ecosystems by various pollutants has been a concern recent decades because of the devastating effect posed on stability between receiving water bodies and biodiversity therein. Indigofera tinctoria used variety fields, including health medicine, as well industrial applications such textiles. The impacts I. freshwater fishes, mechanisms underlying biological effects, are, ho...

Examination of eight microsatellite DNA loci revealed high levels of genetic differentiation among populations of the African bonytongue Heterotis niloticus from three river basins that constitute important fishing areas in Benin. Low levels of population genetic differentiation were detected within the Ouemé-Sô River floodplain system. These results have important implications for conservation...

Streptococcus agalactiae is a pathogen that causes severe anthropozoonosis within a broad range of hosts from aquatic animals to mammals, including human beings. Here, we describe the draft genome of S. agalactiae HZAUSC001, a low-virulent strain isolated from the gut of a moribund tilapia (Oreochromis niloticus) in China.

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, the Lancefield group B streptococcus (GBS) long recognized as a mammalian pathogen, is an emerging concern with regard to fish. We show that a GBS serotype Ia multilocus sequence type ST-7 isolate from a clinical case of human neonatal meningitis caused disease and death in Nile tilapia (Oreochromis niloticus).

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.

Penelitian ini merupakan penelitian eksperimental yang bertujuan mengetahui pengaruh umur ikan terhadap akumulasi logam Pb (NO3)2 dengan konsentrasi 25 ppm pada organ insang dan hati, gambaran histologi sintasan dilaksanakan selama 7 (tujuh) hari. Populasi digunakan adalah Nila (O. niloticus) berumur 1 bulan, 2 3 bulan. Sampel yaitu hati Hasil menunjukkan bahwa rata-rata nilai tertinggi perlaku...

Fish nutrition researchers often feed fishes at between 3-5% of their body weight daily. Environmental risks associated with excess feed leachate are so enormous in tropical waters leading to algal bloom which can toxify the aquaculture products and threaten their safety. Considering that feed requirements by fishes depend on a number of factors such as size, health status and the general condi...

Infection of Nile tilapia Oreochromis niloticus by monogeneans of the genus Cichlidogyrus is harmful. Currently, diagnosis of this infection is based on invasive techniques and the identification of isolated parasites by their morphology. To facilitate diagnosis, we have developed a non-lethal polymerase chain reaction (PCR) test for detection of Cichlidogyrus spp. DNA in the gill mucus of O. n...
