Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this goal has been hampered by the lack of accurate basic information on the genetic parameters of feed efficiency in fish.

To the best of our knowledge, no study has investigated replacing chemical fertilizers with fish effluents in marjorana production in a combined aquaculture agriculture system. The main objective of this study was to investigate the effect of Nile tilapia (Oreochromis niloticus) fish effluent water on the growth parameters, herbage yield, and essential oil composition of sweet marjoram.

Temperature adaptation of biological molecules is fundamental in evolutionary studies but remains unsolved. Fishes living in cold water are adapted to low temperatures through adaptive modification of their biological molecules, which enables their functioning in extreme cold. To study nucleotide and amino acid preference in cold-water fishes, we investigated the substitution asymmetry of codons and amino acids in protein-coding DNA sequences between cold-water fishes and tropical fishes.

Captive animal populations, be it for food production or conservation programmes, are often maintained at densities far beyond those in natural environments, which can have profound effects on behaviour, immune and stress levels, and ultimately welfare. How such alterations impact transcriptional responses to pathogen infection is a ‘different kettle of fish’ and remains poorly understood.

Streptococcus agalactiae (GBS) is a major pathogen of Nile tilapia, a global commodity of the aquaculture sector. The aims of this study were to evaluate protein expression in the main genotypes of GBS isolated from diseased fishes in Brazil using a label-free shotgun nano-liquid chromatography-ultra definition mass spectrometry (nanoLCUDMSE ) approach and to compare the differential abundance of proteins identified in strains isolated from GBSinfected fishes and humans.

Tilapia is one of the most abundant species in aquaculture. Hypoxia is known to depress growth rate, but the genetic mechanism by which this occurs is unknown. In this study, two groups consisting of 3140 fish that were raised in either aerated (normoxia) or non-aerated pond (nocturnal hypoxia).

Body traits are generally controlled by several genes in vertebrates (i.e. polygenes), which in turn make them difficult to identify through association mapping. Increasing the power of association studies by combining approaches such as genotype imputation and multi-trait analysis improves the ability to detect quantitative trait loci associated with polygenic traits, such as body traits.

The present study was carried out on the fingerlings of Nile tilapia (Oreochromis niloticus) to investigate the effect of ‘Guar sprout meal (GSM)’ as a potential protein replacement of fishmeal. The experiment was set in triplicate with five isonitrogenous and isolipidic containing guar sprout meal at an inclusion rate of 0, 25, 50, 75 and 100% respectively.

Nile Tilapia (Oreochromis niloticus) is an important aquaculture resource that represents one of the most popular cultured species in the whole world. However, culture of this species face some problems, which are associated with the occurrence of pathogenic bacteria and cause high pecuniary loss. The main aim of this study was to isolate and identify the pathogenic bacteria from diseased farmed O. niloticus and to detect the antibiotic sensitivity with some commonly used antibiotics.

The present study aimed to assess the acute toxicity effects of herbicide, glyphosate on Nile tilapia (Oreochromis niloticus). The bioassay experiments were performed in a static renewal regime with Oreochromis niloticus exposing to varying acute toxicity concentrations of glyphosate viz., 15.33, 30.67, 61.34, 122.68 and 245.36 mg/l for 96 hrs and the gill, liver and kidney tissues were dissected out. The standard histology protocol was followed to study the histological alterations. In the present study, 100 % mortality was observed in concentrations of 122.68 and 245.

The present study was carried out to evaluate the effect of oxytetracycline (OTC)- dosing at five different concentrations, viz., 0 mg (0X), 80 mg (1X), 240 mg (3X), 400 mg (5X) and 800 mg (10X) kg-1 biomass day-1 for 30 consecutive days on the growth, safety and intestinal histology of Nile tilapia, Oreochromis niloticus (L.) juveniles. The OTC-residues in the edible muscle were detected at scheduled intervals by LCMS/MS. A dose-dependent decline in feed intake, biomass and survival were recorded in OTC-dosed fish. The OTC-residue levels were 0, 204.75±45.75, 318.00±0.00, 778.50±145.

There is a need to identify the presence of lesions in fish skin as soon as they erupt. Fish skin lesions are either macroscopic (can be visualized by the naked eye) or microscopic (difficult to detect with the naked eye). Skin wounds resulting in loss of the epithelium (superficial or deep ulcers) are serious as they may interfere with osmoregulation and open portals for opportunistic pathogens. Herein, we report on the use of a fluorescein dye for the detection of skin ulcers that cannot be seen by the naked eye.

The current study was designed to investigate the potential effect of Spirulina platensis, Arthrospira platensis, (SP) on tissue protection of Nile tilapia (Oreochromis niloticus) through estimation of P53 level. Five isonitrogenous and isocaloric rations containing graded levels of dried SP 5, 7.5,10, 15, and 20 g/kg diet were fed separately to five equal groups of O. niloticus fingerlings, additional control group was assigned for 3 months. Liver samples were separately collected from each group by the end of each month.

Chromium has been recognized as a new and important micro-nutrient, essential for both human and animal nutrition. This study was conducted to evaluate the appropriateness and/or the use of safety level of dietary chromium picolinate (Cr-Pic), and its effects on the physiological responses, the histometric characteristics, and the chemical analysis of dorsal muscles of mono-sex Nile tilapia, Oreochromis niloticus. niloticus. A total of 420 fingerlings (28.00 ± 0.96 g) were randomly distributed into 21 fiberglass tanks representing seven treatments at a rate of 20 fish m3 .
