Lysozyme transgenic Atlantic salmon (Salmo salar L.)
Disease outbreaks are a major constraint to salmon aquaculture worldwide. Therefore, there is considerable interest in ¢nding means to alleviate this problem by enhancing their innate immune system. Because lysozyme is an important component of this system, we generated a line of transgenic Atlantic salmon using a gene construct consisting of a rainbow trout lysozyme gene under the control of t...

متن کاملEffect of feeding rate on nutrient digestibility in Atlantic salmon, Salmo salar L.
A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s were all s...
متن کاملThe Atlantic salmon (Salmo salar L.) is a migratory species
that has a remarkably variable and flexible life history. Adult salmon spawn in fresh water in the autumn and winter, burying their eggs in river bed gravels (Stabell, 1984); the eggs hatch and the fry emerge the following spring. Young fish, known as parr, spend between 1 and 5 years in the river before smolting and migrating to the sea. Oceanic migrations take salmon to feeding grounds where ...
