Testosterone nanoemulsion produced masculinized Nile tilapia (Oreochromis niloticus)

Fish Physiology and Biochemistry, 2022
The objective of this work was to develop a food additive for the sex reversal of Nile tilapia (Oreochromis niloticus) based on a simple oil in water (O/W) nanoemulsion with testosterone propionate for incorporation into commercial feed. Oil screening and evaluation of the organoleptic and physicochemical characteristics were carried out to determine ...

Dietary cholesterol and aggression in Nile tilapia Oreochromis niloticus

Applied Research, 2023
AbstractTilapia farmers would benefit tremendously if they could decrease aggression among fish. Conspecific aggression affects the growth, feed conversion, and general well‐being of fish. Previous studies established an inverse relationship between blood cholesterol levels and aggression in fish, whereby a decrease in cholesterol led to an increase in

Cloning and expression of boule and dazl in the Nile tilapia (Oreochromis niloticus)

Gene, 2014
The Deleted in Azoospermia (DAZ) family of RNA binding proteins consists of highly conserved genes boule, daz and daz-like (dazl) essential for germ cell development. boule is known for its unisexual meiotic expression in invertebrates and mammals, but meiotic-specific female expression plus meiosis-preferential male expression in trout, and meiosis ...

Histopathology of “hole-in-the-head” disease in the Nile Tilapia, Oreochromis niloticus

Aquaculture, 2007
Abstract The gross morphology and histopathology of lesions formed in “hole-in-the-head” disease, commonly found in cichlids, is described in the Nile Tilapia, Oreochromis niloticus . The most severe lesions, which in some fish extended into the lateral line canals, were found posterior to the eye.

Pharmacokinetics and bioavailability of cefuroxime in Nile tilapia (Oreochromis niloticus)

Veterinary Research Communications
Cefuroxime is a broad-spectrum antibiotic extensively utilized in humans and animals. Although it has been reported as beneficial against certain fish infections, pharmacokinetic studies are lacking. The purpose of this study was to evaluate the pharmacokinetics of cefuroxime following intravascular (IV, n = 72), intraperitoneal (IP, n = 72 ...

Dietary copper exposure and recovery in Nile tilapia, Oreochromis niloticus

Aquatic Toxicology, 2006
There are few reports of dietary copper (Cu) toxicity to warm water species of freshwater fish, and little is known about recovery from dietary Cu exposure. In this study Nile tilapia (Oreochromis niloticus) were fed to satiation on a Cu-loaded diet (2000 mg Cu kg(-1)dry weight (dw) feed), or a control diet (3 mg Cu kg(-1)dw feed), for 42 days.

Experimental infection of Tilapia Lake Virus (TiLV) in Nile tilapia ( Oreochromis niloticus ) and red tilapia ( Oreochromis spp.)

Veterinary Microbiology, 2017
Since 2015, a novel orthomyxo-like virus, tilapia lake virus (TiLV) has been associated with outbreaks of disease and massive mortality of cultured Nile and red tilapia (Oreochromis niloticus and Oreochromis spp., respectively) in Thailand. In this study, TiLV was isolated from field samples and propagated in the permissive E-11 cell line, with ...

Nitrite-induced methemoglobinemia in Nile tilapia, Oreochromis niloticus

Journal of Applied Ichthyology, 2006
Summary Exposure of Nile tilapia, Oreochromis niloticus (mean weight, 55.72 ± 4.30 g), to two sublethal NO2–N concentrations was studied for 24 and 48 h in a static test. In nitrite exposure tests, the percentages of methemoglobin, external nitrite, plasma nitrite, hemoglobin and hematocrit were assessed.

Masculinization of Nile tilapia (Oreochromis niloticus) by immersion in androgens

Aquaculture, 1999
Abstract The use of all-male populations increases the efficiency and feasibility of tilapia aquaculture. The objective of this study was to determine the efficacy of a short-term immersion procedure for masculinizing Nile tilapia (Oreochromis niloticus).
