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.

Agonistic profile and metabolism in alevins of the Nile tilapia

Physiology & Behavior, 1995
Metabolic differences derived from social stress usually show data with high variance that may hinder the finding of important differences. Since such high variance may be caused by agonistic variability occurring during social interactions, this work tested whether metabolism is associated with agonistic profile in the cichlid fish Nile tilapia ...

Preparation of the monoclonal antibody against Nile tilapia Igλ and study on the Igλ+ B cell subset in Nile tilapia

Fish & Shellfish Immunology, 2023
Immunoglobulins (Igs) are important effector molecules that mediate humoral immunity. A typical Ig consists of two heavy and two light chains. In teleosts, three Ig heavy chain isotypes (Igμ, Igδ and Igτ) and three Ig light chain isotypes (Igκ, Igλ and Igσ) have been identified.

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 ...

Hemoparasite and hematological parameters in Nile tilapia

Comparative Clinical Pathology, 2012
The accelerated growth of finfish aquaculture has resulted in a series of health problems, including blood disorders by hemoparasites; there are scarce studies about these agents and their impact in actual intensive farming. The aim of this study was to identify and quantify the hemoparasites present in monocytes and erythrocytes in the blood of ...

Levels of copper in Nile tilapia from Brazil

Food Additives and Contaminants: Part B, 2011
The purpose of this work was to determine the concentration of copper in samples of farmed Nile tilapia (Oreochromis niloticus L.) fillets purchased in the city of Botucatu (São Paulo, Brazil) and in fillet and liver samples of Tilapia fed diets supplemented with different concentrations of Cu from the Laboratory of Aquatic Organism Nutrition/FMVZ ...

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 ...

Nile Tilapia Oreochromis niloticus (L.)

2017
Nile tilapia Oreochromis niloticus (L.) is one of the most widely cultured and most widespread invasive fish species globally. It was the most common alien fish species in South China where it has successfully established populations in the major rivers, and became the dominant species in many sites.

Nile tilapia invades the Lake Malawi catchment

African Journal of Aquatic Science, 2013
The Lake Malawi/Nyasa catchment contains over 835 endemic cichlid fish species. This unique biodiversity has made it widely recognised as one of the world’s most significant freshwater ecosystems. Here we report the first occurrence records of two invasive tilapiines, Oreochromis niloticus and Oreochromis leucostictus, inside the Lake Malawi catchment.

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 ...
