Relative Importance of Additive Genetic and Maternal Sources of Variation in Early Survival of Young Splake Hybrids (Salvelinus fontinalis × S. namaycush) Article April with 8 Reads. The survival, performance, and susceptibility to Myxobolus cerebralis infection of the two possible crosses between lake trout Salvelinus namaycush and brook trout S. fontinalis were compared over. The inheritance of mobility and positioning characteristics of F1 and back-cross hybrids of lake charr (Salvelinus namaycush) and brook charr (S. fontinalis) was investigated. In an effort to replace the loss of yield from the cold-water habitat, a fast growing and early maturing hybrid trout (splake [S. namaycush S. fontinalis]) and its backcross to lake trout were.
Juvenile brook charr (Salvelinus fontinalis) are territorial and have high levels of agonistic le lake charr (S. namaycush) rarely show any indication of territoriality and have very low levels of agonistic inheritance of behaviour in their reciprocal hybrids was investigated by multivariate stepwise discriminant analysis. The first investigations of the latter type among salmonids were carried out by Ayles () on the fertile hybrid, splake (Salvelinus fontinalis X S. namaycush), at the third generation level. This author reported evidence of large maternal effects, particularly on egg survival, and of signif icant paternal effects at the alevin stage only. G.B. AylesRelative importance of additive genetic and maternal sources of variation in early survival of young splake hybrids (Salvelinus fontinalis x S. namaycush) J. Fish. Res. Bd. Can., 31 (), pp. The brook trout produces hybrids both with its congeners Salvelinus namaycush and Salvelinus alpinus, and intergeneric hybrids with Salmo trutta.. The splake is an intrageneric hybrid between the brook trout and lake trout (S. namaycush).Although uncommon in nature, they are artificially propagated in substantial numbers for stocking into brook trout or lake trout habitats.
Triploid (heat-shocked) and diploid groups of rainbow trout (Oncorhynchus mykiss), brook trout (Salvelinus fontinalis), coho salmon (Oncorhynchus kisutch), and reciprocal hybrids were produced, monitored for early life stage survival, and evaluated for susceptibility to infectious haematopoietic necrosis virus (IHNV). The female rainbow trout × male brook trout triploid hybrids had. Ayles, G.

Ontario Ministry of Natural Resources, Ontario Fisheries Technical Report Series 6, Toronto, Canada. Arctic char (Salvelinus alpinus) and brook trout (Salvelinus fontinalis) hybridize and their offspring is viable and fertile. This may be a real treat for the native European stocks of Arctic char which gene pools might be unintendedly contaminated with the genetic elements of brook trout. On the other hand, hybrids of these two species are appreciated by customers and have some potential for.
