Environmental conditions required for intensive farming of Arctic charr (Salvelinus alpinus (L.))

The role of Salvelinus in contemporary studies of evolution, trophic ecology and anthropogenic change

“…Increasingly, however, genetics has come to play a major role in aquaculture study, particularly as the role of selection is better understood and exploited. Thus, Saether et al (2016) examined the role that the known plasticity of Arctic charr might play in the adaptation of the species under aquaculture conditions and concluded that plasticity is both a strength and a weakness for the species in aquaculture systems. The capability of Arctic charr to express considerable variation in growth rate and age at sexual maturation is arguably disadvantageous to commercial culture.…”

Tests of size and growth effects on Arctic charr (Salvelinus alpinus) otolith δ18O and δ13C values

“…Otoliths were obtained from n = 50 randomly selected Arctic charr of Lake Hornavan origin used in selective breeding experiments completed by the Swedish Arctic charr breeding programme at Aquaculture Centre North, a Swedish Fisheries Board research station in Kälarne (62°58’N, 16 ° 06′E), Jamtland County, Sweden . Individuals were raised from October 2008 matings in a common tank at rearing densities within the 60–150 kg m −3 range recommended for Arctic charr aquaculture where aggression and agonistic behaviour are reduced and growth is improved . Rearing waters were natural and were sourced from a nearby lake with temperatures that followed a natural seasonal cycle, i.e.…”

Induction of Spontaneous Captive Spawning, Embryonic Development and Larval Rearing in Mystus cavasius

“…Moreover fry younger than 18 days age were significantly cannibalistic. Cannibalism, considered to be caused due to a variety of factors (Hecht and Appelbaum 1988;Sogard and Ollah, 1994;Saether et al, 2015), is considered a major bottleneck in larval rearing of farmed catfishes (Mukai et al, 2013).Therefore, in view of the better adaptability at around 18 to 20 days of age, we recommend this age for stocking in earthen ponds.…”
