Exploring the morphological dynamics of Nile tilapia (Oreochromis niloticus Linn. 1758) in Victoria Nile as depicted from geometric morphometrics

BMC Zoology, 2023
Background Various anthropogenic activities continue to threaten the fish biodiversity of the East African water bodies such as the Victoria Nile. Although the Victoria Nile is a significant source of livelihood for human populations, the biology and ...

Immunological insights into the resistance of Nile tilapia strains to an infection with tilapia lake virus

Fish & Shellfish Immunology, 2022
The emergence of viral diseases affecting fish and causing very high mortality can lead to the disruption of aquaculture production. Recently, this occurred in Nile tilapia aquaculture where a disease caused by a systemic infection with a novel virus named tilapia lake virus (TiLV) caused havoc in cultured populations.

Species diversity defends against the invasion of Nile tilapia (Oreochromis niloticus)

Knowledge and Management of Aquatic Ecosystems, 2014
Nile tilapia (Oreochromis niloticus) is one of the most widely cultured species globally and has successfully colonized much of the world. Despite numerous studies of this exotic species, how differences in native communities mitigate the consequences of

Mitochondria Dysfunction and Cell Apoptosis Limit Resistance of Nile Tilapia (Oreochromis niloticus) to Lethal Cold Stress

Animals, 2022
Inability of Nile tilapia (Oreochromis niloticus) to withstand cold stress represents a major economic concern, which restricts the culture area, limits the growing period and even results in mass mortality in cold seasons.

Bacterial pigment for Nile tilapia feeding [PDF]

Aquaculture International, 2015
The aim of this study was to evaluate the effects of different carotenoids sources in tilapia fish diets on the animals’ performance and fillets characteristics. Nine hundred and sixty tilapias, Oreochromis niloticus, averaging 15 g were distributed into 24 tanks to receive one of the six treatments (four repetitions) for 80 days: basal diet with no ...

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Dietary four different woody forages differentially affect the growth, feed utilization, apparent digestibility, intestinal morphology and microbiota composition in Nile tilapia (Oreochromis niloticus)

Aquaculture Reports, 2021
Woody forage as potential aquatic feed ingredient has a positive effect on tilapia survival and feed utilization. To study the effect of woody forages on the growth, feed utilization, apparent digestibility, intestinal morphology and microbiota ...

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

MICROBIOLOGICAL QUALITY OF FILLETED FISH WITH SPECIAL REFERENCE TO LISTERIA MONOCYTOGENES [PDF]

Assiut Veterinary Medical Journal, 2010
Imported (Saba) and local (Tilapia nilotica and Nile perch) flitted fish (60 samples) were analyzed for aerobic colony count (ACC), total coliform count and for presence of Listeria monocytogenes to detect their quality.
