Combined effects of dietary malic acid and Bacillus subtilis on growth, gut microbiota and blood parameters of Nile tilapia (Oreochromis niloticus)

open access: yes, 2018
The study investigated effect of dietary supplementation with malic acid, Bacillus subtilis and a mixture of the two (3 × 2 factorial trial) on Nile tilapia (Oreochromis niloticus) health.

Predictions of fish yields and the status of the Kainji Lake fishery, 1998 [PDF]

open access: yes, 1999
Length frequency data was collected for the 6 main species from the Kainji Lake fishery for up to 16 months. Growth parameters were estimated and used for virtual - population and length based cohort analysis.

Ecotoxicological Evaluation of the Antimicrobial Butylparaben in Edaphic Organisms Using Multiple Biomarkers

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.

Dermocystidium sp. in the gills of farmed Oreochromis niloticus in Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2019
The genus Dermocystidium is very comprehensive in the host and site of infection, however this is the first report of the occurrence of Dermocystidium sp. in the gills of Nile tilapia. This study was carried out in a fish farming located in the state of Santa Catarina, Brazil.

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

open access: yesIntegrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Stock assessment of Lates niloticus (L.), Oreochromis niloticus (L.) and Rastrineobola argentea (Pellegrin) using fishery dependent data from the Tanzanian waters of Lake Victoria [PDF]

open access: yes, 1999
Catch data were collected from three beaches in the Mwanza area of lake Victoria, Tanzania for Oreochromis niloticus (L.), Rastrineobola argentea (Pellegrin) and Lates niloticus (L.).

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Utilization of Catfish Body Fat in the Diet of Tilapia Oreochromis niloticus

open access: yesJurnal Akuakultur Indonesia, 2007
This experiment was conducted to evaluate the effect of catfish body fat in the diet on the growth of tilapia Oreochromis niloticus. Twenty fishes with an initial body weight of 5.0±0.03 g were cultured in 100-ℓ rectangular aquaria for 58 days.

Characterisation of Oreochromis niloticus fish species of Lake Kariba, Zambia, using morphological, meristic and genetic methods

open access: yesAquaculture, Fish and Fisheries, 2022
This study aimed at characterising Oreochromis niloticus fish species of Lake Kariba and was premised on the hypothesis that there are different types of O. niloticus fish species in Lake Kariba.

A high quality assembly of the Nile Tilapia (Oreochromis niloticus) genome reveals the structure of two sex determination regions

open access: yesBMC Genomics, 2017
Tilapias are the second most farmed fishes in the world and a sustainable source of food. Like many other fish, tilapias are sexually dimorphic and sex is a commercially important trait in these fish.
