This study was to assess effects of the pretreatment in allplant based diets with microbial phytase on phosphorous utilization and growth performance of Nile tilapia (Oreochromis niloticus). Pretreatment trials were conducted using phytase at graded doses to determine the optimal dose of phytase. Available phosphorus (P) levels increased significantly with the increased doses of phytase and the...
this study was conducted to determine the residues of mercury (hg), lead (pb), copper (cu) and cadmium (cd) in the imported tilapia fillets. thirty random samples from imported tilapia fillets were collected from different markets in isfahan city, central iran. they were analyzed using graphite furnace atomic absorption spectrometer (perkin elmer 800) for pb, cu, cd and flow injection mercury s...
SYNOPSIS. Certain teleost fish have large anatomically discrete islet organs called Brockmann bodies (BBs). When transplanted into streptozotocin diabetic athymic nude mice, tilapia BBs provide long-term normoglycemia. This has afforded us the opportunity to examine tilapia islet in vivo function in a non-piscine environment and compare this with in vivo function in the donor species. As expect...
An experiment on integrated walking catfish-tilapia culture was conducted for 5 months. The walking catfish were stocked at 400 and 800 fish/cage in two 4-m nylon cages, which were suspended in each of two 250-m earthen ponds. Sex-reversed male tilapia (Oreochromis niloticus) were reared at 1 fish/m2 in the open pond. Whereas the catfish were reared with supplemental feed, tilapia were solely d...

Gill cell suspensions from freshwater (FW)- and seawater (SW)-adapted teleosts were obtained by density gradient centrifugation. The proportion of chloride cells (CCs) in the mixed cell suspensions was estimated using the fluorescent mitochondrial stain, DASPMEI, and ranged from less than 1% (FW-adapted tilapia) to approximately 13% (SW-adapted toadfish). The gill cells displayed relatively hig...
UNLABELLED Tilapia are an important global food source due to their omnivorous diet, tolerance for high-density aquaculture, and relative disease resistance. Since 2009, tilapia aquaculture has been threatened by mass die-offs in farmed fish in Israel and Ecuador. Here we report evidence implicating a novel orthomyxo-like virus in these outbreaks. The tilapia lake virus (TiLV) has a 10-segment,...
Experiments were conducted to assess the effects of polyculture on tilapia growth and to evaluate African catfish (Clarias gariepinus) as a predator control for unwanted tilapia offspring in a polyculture system. Three treatments were tested using nine 200 m earthen ponds. Ponds were stocked with male tilapia in treatment 1 (Tl), mixed sex tilapia in treatment 2 (T2), and mixed sex tilapia and ...
Natural selection and selective breeding for genetic improvement have left detectable signatures within the genome of a species. Identification of selection signatures is important in evolutionary biology and for detecting genes that facilitate to accelerate genetic improvement. However, selection signatures, including artificial selection and natural selection, have only been identified at the...
