Role of Cortisol in Hypoosmoregulation in Larvae of the Tilapia (Oreochromis mossambicus)

General and Comparative Endocrinology, 1993
The total cortisol content in tilapia was 55 pg immediately following fertilization, then decreased abruptly and maintained a lower level of 10-20 pg until hatching; after hatching the cortisol content increased to 50 pg by the 7th day. Fertilized eggs were incubated in either 32% saltwater or fresh water and sampled at various developmental stages ...

Effects of temperature on the deformity and sex differentiation of tilapia,Oreochromis mossambicus

Journal of Experimental Zoology, 2000
The effects of temperature on the deformity and sex differentiation of tilapia, Oreochromis mossambicus, were investigated. Zero- (the hatching day), 5-, and 10-day-old tilapia were respectively divided into 4 groups that were reared at 20, 24, 28, and 32 degrees C for 5 days. Percentages of deformity were significantly increased when tilapia were kept

In vitro propagation of tilapia lake virus in cell lines developed from Oreochromis mossambicus.

Journal of Fish Diseases, 2019
Tilapia lake virus (TiLV)-suspected samples of tilapia were collected from grow-out ponds located with clinical signs and mortality ranged from 5% to 50%. The reverse transcription-polymerase chain reaction (RT-PCR) assay revealed the presence of TiLV in

Structure of the Tilapia (Oreochromis mossambicus) Prolactin I Gene

DNA and Cell Biology, 1992
The tilapia (Oreochromis mossambicus) prolactin-I (PRL-I) gene has been cloned and sequenced. Its transcript (3,677 bases long) begins with a guanine and is organized in five exons and four introns like the other known prolactin genes. Analysis of the 1,555-bp 5'-flanking region suggests that pituitary-specific expression of the gene could be regulated

Salinity tolerance in superior genotypes of tilapia, Oreochromis niloticus, Oreochromis mossambicus and their hybrids

Aquaculture, 2005
Abstract Tilapias are important candidate species for brackish water aquaculture and are increasingly cultured in coastal ponds including in polyculture with shrimp, thus creating a demand for tilapia genotypes well suited to elevated salinities. The Nile tilapia Oreochromis niloticus dominates freshwater tilapia culture and has been the subject of

Production of all-female sterile-triploid Oreochromis mossambicus

Aquaculture, 1990
All-female triploids were produced by heat shocking 2.5-min-old eggs which had been fertilized with sperm from a masculinized female (XX-♂). Induction of triploidy was confirmed using the estimates of red blood cell (RBC) nuclear volume. Ovaries of the control diploids were packed with oocytes, while those of triploids contained only one or two poorly ...

Effects of cortisol on growth and development in tilapia larvae,Oreochromis mossambicus

Fish Physiology and Biochemistry, 1996
Treatment of one-day-old yolksac larvae of tilapia (Oreochromis mossambicus), by immersion in cortisol solution for two weeks, significantly enhanced growth. The standard length, tail length, head width and wet weight showed dose-dependent increases at concentrations of cortisol (hydrocortisone) from 0.05 ppm to 0.5 ppm, with no further increase at 1.0
