This work delivers a fundamental step in the empirical examination of this emerging aquaculture species and provides a model for evaluating osmoregulatory performance of marine stenohaline fishes in low-salinity aquaculture.Īhmed N, Turchini GM (2021) Recirculating aquaculture systems (RAS): environmental solution and climate change adaptation. It is an important finding that fish considered to be a typical marine stenohaline organism could maintain ion and water balance as low as the isosmotic point, and exhibit survival and positive growth rates in salinities as dilute as 6 ‰. Segmental linear regression analyses revealed that the calculated isosmotic point for wolf eel of ~ 10.6 ‰ was a critical limit for maintaining growth performance and osmoregulatory homeostasis. Muscle water content increased with increasing salinity dilution (77.9% water in 30 ‰ 79.8% water in 6 ‰), and plasma osmolality (~ 320 mOsm kg −1) was maintained in salinities as dilute as 9 ‰ but was significantly lower (~ 280 mOsm kg −1) in the most dilute salinity of 6 ‰. Specific growth rate was maintained above 3.0% mass day −1 at salinities of 30 and 14 ‰, but was significantly reduced at 9 (2.9% mass day −1) and 6 ‰ (2.0% mass day −1). Growth rate remained positive in all salinities throughout the 8-week trial. ![]() At the conclusion of the growth study, fish were sampled for analysis of gill and intestine enzyme activity, plasma ion content, and muscle moisture. This study examined growth performance and osmoregulation in juvenile wolf eel ( Anarrhichthys ocellatus) held in a series of dilute salinities (30, 14, 9, and 6 ‰) over an 8-week trial. Members of wolf fish family Anarhichadidae have emerged as potential cold-water marine aquaculture species.
