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 ...

Low Luminosity Reduces Agonistic Behaviour of Nile Tilapia

Journal of Applied Animal Welfare Science, 2021
In confrontations, many behaviors are based on visual information. To establish the importance of visual signals in the aggression of cichlid fish, we observed the behavior of groups in three juveniles of Nile tilapia (six groups in each condition), for 30 minutes under two extremes of light condition: high luminosity and low luminosity (dark condition

Diseases resistance of Nile tilapia (Oreochromis niloticus), blue tilapia (Oreochromis aureus) and their hybrid (female Nile tilapia×male blue tilapia) to Aeromonas sobria

Aquaculture, 2004
Abstract The resistance to disease caused by the Aeromonas sobria in three genotypes of tilapia, Nile tilapia ( Oreochromis niloticus ), blue tilapia ( Oreochromis aureus ) and their hybrid (female Nile tilapia×male blue tilapia) was studied . Based on comparison of median lethal dose (LD 50 ), functions of nonspecific immunity, including total ...

Purification and Localization of Nitric Oxide Synthases from Hybrid Tilapia (Nile Tilapia × Mozambique Tilapia)

Journal of Aquatic Animal Health, 2007
Abstract The aims of this study were to purify and localize the nitric oxide synthases (NOSs) from hybrid tilapia (Nile tilapia Oreochromis niloticus × Mozambique tilapia O. mossambicus). The purification procedures involved affinity chromatography with a 2′, 5′-ADP-agarose 4B column and ion exchange with a diethylaminoethanol Bio-Gel A ...

Conditioning of stress in Nile tilapia

Journal of Fish Biology, 2004
A Pavlovian conditioning paradigm was used to induce a connection between a conditioned stimulus, light (CS), associated with an unconditioned stimulus, confinement (US) in Nile tilapia Oreochromis niloticus, which resulted in a conditioned endocrine response (CR) to the CS alone manifested as an increase in plasma cortisol.

Amino Acid Requirements for Growth of Nile Tilapia

The Journal of Nutrition, 1988
A series of feeding experiments was conducted in aquaria to determine the quantitative requirements of the 10 essential amino acids for growth of young Nile tilapia (Oreochromis niloticus). The test diets contained casein and gelatin supplemented by crystalline L-amino acids to provide an amino acid profile similar to 28% whole egg protein except for ...

Time-place learning in food-restricted Nile tilapia

Behavioural Processes, 2008
Time-place learning based on food association was investigated in eight food-restricted Nile tilapias. Each fish was individually housed for 10 days in an experimental tank for adjustments to laboratory conditions, and fed daily in excess. Feeding was then interrupted for 17 days.

Nile Tilapia Fish Skin–Based Wound Dressing Improves Pain and Treatment-Related Costs of Superficial Partial-Thickness Burns: A Phase III Randomized Controlled Trial

Plastic and Reconstructive Surgery, 2021
Background: In a phase II study comparing Nile tilapia fish skin to silver sulfadiazine cream for outpatient management of superficial partial-thickness burns, the fish skin decreased reepithelialization time (average reduction, 1.43 days), dressing ...
