Thermal dependence of embryonic growth and development in brown trout
Fertilized eggs from a brown trout Salmo trutta population in northern Spain were incubated in the laboratory at 4, 6, 8, 10, 12, 14, 16 and 18° C. Developmental stage and embryo size were monitored… Expand

Growth rate, food intake and activity of juvenile brown trout (Salmo trutta L.) were studied at 10 constant temperatures (2.6-22.3 degrees C) and using eight full-sib families. We found… Expand
Effects of size and morphology on swimming performance in juvenile brown trout (Salmo trutta L.)
Abstract – Our study assesses swimming capacity (speed and stamina) and possible morphometric determinants of locomotor performance of juvenile brown trout (Salmo trutta L.). We addressed these… Expand
Thermal dependence of swimming endurance in juvenile brown trout
The maximum swimming stamina of hatchery reared juvenile brown trout Salmo trutta, swimming against a fixed-velocity water flow of 36·6 cm s-1 (6·97 L s-1), was achieved at 16·1° C, and a 90%… Expand
Effects of egg size on offspring development and fitness in brown trout, Salmo trutta L.
Abstract To examine the effects of egg size on initial fry size and performance in brown trout ( Salmo trutta L.) we reared, under common hatchery conditions, the broods produced by females of the… Expand
Effects of Temperature on Growth and Efficiency of Yolk Utilisation in Eggs and Pre-feeding Larval Stages of Atlantic Salmon
Three embryonic stages of Atlantic salmon (Salmo salar L.) were subjected to eight constant incubation temperatures (4, 7, 10, 12, 14, 16, 19 and 22 °C) exceeding the range usually experienced in… Expand
Ontogeny of critical swimming speed of wild-caught and laboratory-reared red drum Sciaenops ocellatus larvae
Critical swimming speed (Ucrit) provides a useful estimate of maximum swimming per- formance for fish larvae that can be used to assess transport and migratory potential. We measured Ucrit of red… Expand
Effect of short-term preservation of sea lamprey gametes on fertilisation rate and embryo survival
We assessed the effect of short-term (4.7–75.3 h) storage at low temperature (approximately 1 °C) on the viability of sea lamprey (Petromyzon marinus L.) gametes. Hatching success decreased with… Expand
The ontogenetic development of body segments and sexual dimorphism in brown trout (Salmo trutta L.)
Nonmigratory brown trout (Salmo trutta L.) from northern Spain showed no between-sex differences in total length or mass and only moderate, but significant, dimorphism in some morphometric traits.… Expand
Discrimination against Water Containing Unrelated Conspecifics and a Marginal Effect of Relatedness on Spacing Behaviour and Growth in Juvenile Brown Trout, Salmo trutta L.
In this study, we assessed whether juvenile brown trout are able to discriminate between, and swim towards, water containing unrelated conspecifics and blank stream water. In a second stage we… Expand
