Abstract:
... This study describes the patterns of mortality and investigates the sources of variation in mortality during the marine phase of commercial salmon farming. The study included daily mortality records from stocking to harvest of 21 million salmon from ten hatcheries in 136 fish‐groups (fish in the same cage from the same hatchery). The fish was stocked in 2017–2018 at 21 marine farms within two Norw ...

Abstract:
... Lake Ontario Atlantic salmon (Salmo salar) were one of the first species of fish to be cultured in Canada. Their story goes from abundance in the 1700s to protective legislation in 1807, then hatchery culture in 1866 and finally ends in extirpation in 1898. The standard narrative is that Samuel Wilmot’s hatchery efforts briefly staved off their loss from the Lake Ontario basin. However, that story ...

Abstract:
... Coral trout Plectropomus leopardus is a high-economical value of marine fish commodity. So, the larviculture for this species should be performed in hatchery scale for their sustainability. One of the important thing in larval stage is hormonal mechanisms. Thyroid hormone is known plays an important role in the metamorphosis of marine fish larvae. The source of that hormone is assumed derived from ...

Abstract:
... Monosex culture was proven to be an effective rearing method for grow-out, but in a closed-cycle hatchery, males and females are usually reared communally in tanks until maturation. This study determined the effect of communal rearing (CR) and separate rearing (SR) on male and female Penaeus indicus broodstock gonad maturation. This study also evaluated the influence of the rearing method on repro ...
