Protection of teleost fish against infectious diseases through oral administration of vaccines: Update 2021
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-10)Immersion and intraperitoneal injection are the two most common methods used for the vaccination of fish. Because both methods require that fish are handled and thereby stressed, oral administration of vaccines as feed supplements is desirable. In addition, in terms of revaccination (boosting) of adult fish held in net pens, oral administration of vaccines is probably the only feasible method to ... -
Protein determination - Method matters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-01)The reported protein content of foods depends on the analytical method used for determination, making a direct comparison between studies difficult.
