Efficacy of heat‐killed and formalin‐killed vaccines against Tilapia tilapinevirus in juvenile Nile tilapia (Oreochromis niloticus)

bioRxiv, 2021
Tilapia tilapinevirus (also known as tilapia lake virus, TiLV) is considered to be a new threat to the global tilapia industry. The objective of this study was to develop simple cell culture-based heat-killed (HKV) and formalin-killed (FKV) vaccines for ...

Modulation of Sodium and Ammonia Transporters in the Context of Viral Gill Diseases in Common Carp (Cyprinus carpio)

Journal of Fish Diseases, EarlyView.
ABSTRACT Osmoregulation and ammonia removal are among key physiological processes that take place in gills and affect fish homeostasis and well‐being. These processes can be disrupted by numerous environmental factors, but also by viral infections, especially those leading to severe gill disorders.

Efficacy of a Combined Natural Extract of Turmeric (Curcuma longa) and Liquorice (Glycyrrhiza uralensis) Against Viral Haemorrhagic Septicaemia Virus in Olive Flounders (Paralichthys olivaceus)

Journal of Fish Diseases, EarlyView.
ABSTRACT Viral haemorrhagic septicaemia virus (VHSV) causes a high mortality rate in cultured olive flounder, and effective treatment for VHSV infection is urgently required. Turmeric (Curcuma longa ) and liquorice (Glycyrrhiza uralensis) are well‐known medicinal plants with a variety of biological activities. Turmeric and liquorice extract combination

Cryopreservation of Nile Tilapia (Oreochromis niloticus) Sperm

, 2016
The main aim of this study is to determine the effect of the straw volume (0.25 vs. 0.5 mL) on Nile tilapia sperm quality after cryopreservation. Sperm was frozen according to conventional slow freezing procedure and diluted at ratio of 1:3 with ionic extender containing 350 mM glucose and 30 mM Tris containing 10% dimethylacetamide.

Juvenile Nile Tilapia Fish Avoid Red Shelters

Journal of Applied Animal Welfare Science, 2020
Shelters are frequently used for fish rearing to improve welfare conditions. In this study, whether Nile tilapia prefers specific shelter colors was evaluated. Thus, fish preference for white, red, blue, green or yellow shelters was tested. A high variation of individual preference responses for the shelter colors among fish was found.

Stocking density in the larviculture of Nile tilapia in saline water [PDF]

Revista Brasileira de Zootecnia, 2012
The objective of this study was to assess the possibility of increasing the stocking density in the larviculture of Nile tilapia, Oreochromis niloticus, in saline water. Six-day post-hatched larvae (average weight of 0.09±0.002 g), at the start of the exogenous feeding, were stocked in twelve 8 L tanks at densities of 1, 10, 20 and 30 larvae/L.

Crosstalk between thyroid hormones and the central corticotropin‐releasing factor system in Atlantic salmon

Journal of Neuroendocrinology, EarlyView.
The corticotropin‐releasing factor (CRF) system plays a key role in centrally regulating thyroid hormone (TH) synthesis in non‐mammalian vertebrates, but interactions between THs and the CRF system remain poorly understood in fish. Here, we report that THs directly affect transcription of several CRF system components across different hypophysiotropic ...
