Investigations into endocrine changes associated with photoperiod treatment to arrest or promote puberty in male Atlantic cod

Sexual maturation leads to significant loss of body weight during the spawning season, and farmed cod normally nature at two years of age, before reaching commercial size. Photoperiod treatment is the most efficient strategy to enhance growth and delay pu berty in cod. Continuous light treatment ...

Vekst og kjønnsmodning hos kveite: Interaksjoner og koblinger til lysperiode

Til tross for at gytetidspunkt relativt enkelt lar seg styre i kveite ved hjelp av lysmanipulering, har en ennå ikke lykkes i å finne effektive metoder for å utsette kjønnsmodning og samtidig få økt vekst i hannfisk. Foreløpige resultater antyder at en ko rtdagsperiode kan være effektiv, men vi t...
