”Pulse vs. Continuous Treatment: which is better for applying peracetic acid in RAS?” Organic Eprints
Liu, Dibo; Pedersen, Lars-Flemming; Lazado, Carlo Cabacang; Strauss, David L.; Meinelt, Thomas.
Peracetic acid (PAA) can improve water quality in a way that does not affect the fish, the farmer nor the environment. This presentation included recent findings of ways to improve PAA water treatment strategies. The study compared two distinct way of applying PAA – either as a pulse or as low dose continuous addition. Selected markers to address potential negative impact on fish welfare were used. Cortisol expression was temporarily increased following pulse addition but subsequently fish adapted and cortisole expression remained at low, similar levels as measured among control fish and fish exposed to continuous low dose PAA exposure. Pros and cons about PAA application and its consequences were discussed as well.

Crosstalk between Innate Immunity and Circadian Rhythm: Do fish immune defences have a sense of time? Organic Eprints
Lazado, Carlo Cabacang; Lund, Ivar; Skov, Peter V.; Jokumsen, Alfred; Gesto, Manuel; Nguyen, Huy Quang; Pedersen, Per Bovbjerg.
Circadian rhythms established by the endogenous clocks enable organisms to anticipate periodic and cyclic changes in their environment. This internal time-keeping system is highly conserved amongst animals and provides them with adaptive advantages as biological processes can be scheduled to occur at the most crucial times of the day. Circadian rhythm is emerging as an important regulator of immune functions. However, there is a paucity of information on the influence of this biological phenomenon in the immune mechanisms of teleost fish. A series of studies was conducted to investigate the circadian rhythms of systemic and mucosal innate immunity using model (i.e., zebrafish, Danio rerio) and non-model (i.e., permit, Trachinotus falcatus; rainbow trout,...
