We have cloned and characterized a tilapia (Oreochromis mossambicus) L18 ribosomal protein gene, including the complete transcribed region and 488 bp of upstream regulatory sequences. We have also isolated two L18 cDNAs from another tilapia (Oreochromis niloticus) with a few conservative nucleotide differences. Our results suggest the presence of two genes in both species. Reporter constructs w...

Unique biological characteristics of Nile tilapia (Oreochromis niluticus), including high fecundity, maturation at young ages, well-adapted to environmental conditions, and high resistance again stresses and pathogens, make it a good candidate for aquaculture. However, its potential ecological risks are the major challenges for the decision makers. This study was aimed to study on the feasibili...

In Southeastern Brazil tilapia culture is conducted in extensive and semi-intensive flow-through earthen ponds, being water availability and flow management different in the rainy and dry seasons. In this region lettuce wastes are a potential cheap input for tilapia culture. This study examined the ecological processes developing during the rainy and dry seasons in three extensive flow-through ...

Gills and muscles of Tilapia fish from Naik lake of Nagpur city were estimated for heavy metals (Zinc, Lead, Nickel, Copper and Cadmium) using inductively coupled plasma optical emission spectrometry (ICP-OES). Results showed higher concentrations of heavy metals in gills than in muscles of tilapia fish. Trends of heavy metal concentrations in gills and muscles of tilapia fish were found Zn > P...

The study was conducted to assess the over-wintering growth performance of mixed-sex and mono-sex male tilapia, Oreochromis niloticus. The experiment was carried out with two treatments each with three replicates for a period of 6 months from October 2012 to March 2013 in the Field Laboratory Complex, Bangladesh Agricultural University. In the first treatment (T 1 ), mixed-sex tilapia was stock...

Tilapia (Oreochromis spp.) were collected seasonally from four contaminated rivers in southwestern Taiwan for studies of morphological deformities that could be used as biomarkers of contamination. Morphological deformities found in tilapia were separated into 15 categories. Overall, the prevalence of deformities such as split fins, lower lip extension and gill deformities were significantly re...

Tilapia is an important fish cultured in tropical and subtropical areas. Cold sensitivity limits the expansion of tilapia culture into colder regions of the world, and mass mortalities of cultured tilapia have been reported due to severe cold currents in winter. Since the late 1990s, several strains of Nile tilapia have been domesticated to improve the ability to adapt to low temperatures. Prev...

Cage culture is one of the important methods for intensive culture of tilapia in large water impoundments. But, information related to growth performance of androgen-treated monosex tilapia population during cage culture under the ecological conditions of India is limited. The aim of this study was to compare the growth potential of control, mixed-sex and androgen-treated, monosex tilapia in co...

Tilapia (Oreochromis mossambicus] teleostei) melanin-concentrating hormone gene-related peptide (tMgrp) was tested for tropic actions on adenocorticotropin hormone (ACTH) and a melanocyte s t im u la t in g ho rm one ( a M S H ) producing cells in the tilapia pituitary gland in vitro. Up to 100 pM synthetic tilapia Mgrp (tMgrp) had no effect on a -M S H release from tilapia neurointermediate lo...
