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 ...

Genome-Wide Patterns of Population Structure and Linkage Disequilibrium in Farmed Nile Tilapia (Oreochromis niloticus)

open access: yesFrontiers in Genetics, 2019
Nile tilapia (Oreochromis niloticus) is one of the most produced farmed fish in the world and represents an important source of protein for human consumption.

Digestibility of triticale by Nile tilapia

open access: yes, 2022
This work aimed to determine the dry matter (DM), crude protein (CP), gross energy (GE) and essential aminoacid (EAA) digestibility coefficient of triticale by Nile tilapia. Fish with 112.00 ± 22.00g average weight were used to digestibility test. Reference diet was formulated with purified ingredients and triticale replaced 30% of this diet.

Vitamin A in diets for Nile tilapia [PDF]

open access: yesScientia Agricola, 2009
Dietary vitamin supplementation decrease stress caused by high stocking density, and boosts immunological system of farmed fish. A studied was carried out to determine vitamin A requirements of Nile tilapia (Oreochromis niloticus) in an all male group (13.8 ± 1.2 g) and a mixed sex population (9.8 ± 2.3 g). Fish stocked in 100-L plastic aquaria (26.0 ±

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Selected dietary plant-based proteins for growth and health response of Nile tilapia Oreochromis niloticus

open access: yesAquaculture and Fisheries
Tilapia culture is one of the largest sectors of global aquaculture. Among the different species of tilapia, Nile tilapia (Oreochromis niloticus) is perhaps the top cultured species.

On-farm trials with rice fish cultivation in the west Kano rice irrigation scheme, Kenya [PDF]

open access: yes, 2006
The viability of integrating rice farming with fish culture was studied in ten (10) rice plots. The on-farm research was done during one rice-growing season starting May 2003.

First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing

open access: yesJournal of Fish Biology, EarlyView.
Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...
