The effectiveness of low cost breeding scheme designs for small aquaculture programmes were assessed their ability to achieve genetic gain while managing inbreeding using stochastic simulation. Individuals with trait data simulated over 15 generations selection on a single trait. Combinations methods, mating strategies and evaluation options evaluated without the presence common environmental effects. An Optimal Parent Selection (OPS) method semi-definite programming was compared truncation...
King (Chinook) salmon is the only species farmed in Aotearoa New Zealand and accounts for over half of world's production king salmon. Determining health status effectively important farming. However, it a challenging task due to complex biotic abiotic factors that influence health. Evolutionary machine learning algorithms have shown their superiority models tasks. they not been investigated prediction This paper focuses on data processing algorithm design develop Zealand. Particularly, this...
ABSTRACT The bacterial skin disease tenacibaculosis, caused by Tenacibaculum species, affects numerous economically important marine fish, including salmonids. This study reports the ability of three maritimum strains, belonging to different molecular O‐AGC types, and a single dicentrarchi strain induce tenacibaculosis in farmed Chinook salmon ( Oncorhynchus tshawytscha , Walbaum 1792) Aotearoa New Zealand. Naïve were exposed T. (2 × 10 8 cells/mL) 7 immersion using natural seawater....
Over the past 40 years New Zealand (NZ) aquaculture has grown into a significant primary industry. Tonnage is small on global scale, but industry built an international reputation for supply of high quality seafood to many overseas markets. Since early 1990s recognized potential gains from selective breeding and challenge been develop programs that can overcome biological obstacles (such as larval rearing mortality) operate cost-effectively relatively scale while still providing in multiple...
Gut microbiota play important roles in fish health and growth performance the microbiome has been shown to be a biomarker for stress. In this study, we surveyed change of Chinook salmon ( Oncorhynchus tshawytscha ) gut water freshwater recirculating aquaculture systems (RAS) 7 months evaluated how microbial communities were influenced by performance. The diversity significantly increased parallel with fish. dominant shifted from predominance Firmicutes Proteobacteria, while Proteobacteria...
Exercise regimes provide a promising opportunity to enhance production performance during hatchery rearing, but exercise-enhanced traits are presently poorly understood in Chinook salmon. In addition, spinal health can be concern some farms New Zealand and unfavourable correlations between higher condition factor curvature have been detected. regimes, other salmonids, improved bone mineralisation lowered factor. Therefore, we hypothesise that sustained swimming could used as tool improve...
Abstract The bacterial skin disease tenacibaculosis, caused by Tenacibaculum species, can compromise numerous species of economically important marine fish, including salmonids. While tenacibaculosis is a known threat to Atlantic salmon ( Salmo salar ) aquaculture, the pathogenesis maritimum and dicentrarchi on Chinook Oncorhynchus tshawytscha has not yet been investigated. In this study, three molecular O-AGC types T. (O-AGC Type 3-0, 2-1 3-2) isolated during outbreak farmed in Aotearoa New...
Ocean warming and extreme sea surface temperature anomalies are threatening wild domesticated fish stocks in various regions. Understanding mechanisms for thermotolerance processes associated with divergent growth performance is key to the future success of aquaculture fisheries management. Herein, we exposed Chinook salmon (Oncorhynchus tshawytscha) environmentally relevant water temperatures (19–20 °C) approaching their upper physiological limit three months sought identify blood...
Exercise training during pre-and post-smolt production is becoming a key component in salmon hatcheries as it known to enhance several production-related traits salmonids. conditions for rearing salmonids are continually being optimised and now that the salmonid industry developing offshore, considered tool prepare domestic stocks high energy environments. It unknown if exercise can other understudied species individuals with spinal curvature (scoliosis), which common health concern within...
Fish feeding behaviour can be complicated and time consuming to observe, analyse quantify. The conventional single ballotini X-radiography method was modified determine the timing of within a meal in farmed fish reared at commercial densities. Feed pellets containing two bead sizes were fed different times during meal, either for first half or second meal. differentiated on X-radiographs by human eye semi-automated counting software able count accurately. This dual used assess whether ate...
