Effects of photoperiod and melatonin implants on feed intake in Atlantic salmon (Salmo salar L.) postsmolts
High melatonin concentrations were expected to negatively affect Atlantic salmon appetite. Hence, individually kept Atlantic salmon postsmolts were subjected to continuous light (24:0, L:L) or natural daylight (12:12, L:D) and then given intraperitoneal implants of slow release melatonin in a 2 by 2...
