“…In one study, growth was highest in 34‰ with decreased growth at salinities ranging from 5 to 25‰, 178 while in another, growth only decreased in 10‰ when compared with fish reared in 15–40‰ 177 . Further, the standard metabolic rate of rivulated rabbitfish was lower in 30–40‰ compared with 25‰, suggesting that the higher salinity range minimises metabolic expenditure while maximising growth in this species 179 …”

“…Multiple endpoints have been employed to assess performance in response to salinity, including aerobic scope/metabolic rates and stress responses. 24,179,207,248,[261][262][263] Here, some of the physiological aspects that most directly impact the production of aquacultured species, including growth, reproduction, disease resistance and nutrition are further discussed.…”

The life history, distribution and diversity of fishes are largely influenced by environmental salinity. Changes in salinity affect a range of physiological processes including metabolism, nutrition, reproduction and growth. Therefore, fish can be conditioned to environmental parameters most suitable for production, where distinct traits are optimised through species‐specific manipulation of salinities. The primary purpose of this review is to summarise the existing literature on the salinity tolerance of aquacultured fish. The various experimental approaches for determining salinity tolerance are compared, along with summarised information for key species employed in aquaculture, including their native distributions, life history stage and optimal salinity for survival and growth. The implications for production were assessed by considering the effects of salinity on growth, reproduction, management, disease mitigation and marketability.

“…A Strathkelvin 929 6‐Channel Dissolved Oxygen System was used for respiration measurements. A flow‐through respirometry setup as described by Babikian, Nasser and Saoud () was used. The apparatus consisted of a glass water container (80 × 80 × 80 cm) equipped with a 4,000 ml Erlenmeyer flask, a submersible electric heater to maintain water temperature at 27°C, a thermometer to monitor temperature, and a submersible water pump to maintain a constant water level in the Erlenmeyer flask.…”

Effect of cannabis oil on growth performance, haematology and metabolism of Nile TilapiaOreochromis niloticus

Cannabis sativa is a plant that produces an oil with psychoactive and stress reduction effects and thus illegal in many nations. Lately, the beneficial properties of the plant extract are becoming better understood and perceptions are changing. As the aquaculture industry matures from a primitive extensive pond system to an industrialized intensive system, fish stress and disease incidence are increasing, with negative economic results. A nutritional ingredient that could reduce stress and disease incidence in aquacultured fish would thus be opportune. In the present work we investigated whether ether extracted cannabis oil would relieve stress, improve growth and feed conversion, and/or improve haematological indicators of disease resistance. Three diets were made to contain either soy oil, industrial hemp oil or cannabis oil and offered to tilapia for 8 weeks. At termination, survival, growth, feed conversion and blood parameters were assessed. Fish were returned to their tanks, offered the same feeds as during the experiment and respiration assessed. Cannabis extract was found to increase metabolism and thus increase feed conversion. On the other hand, cannabis had no effect on blood cell counts, total plasma protein, haematocrit or lysozyme activity. Results thus suggest that cannabis does not improve immune response of tilapia or body composition but does reduce growth rate by increasing metabolic rate.

“…However, this trend is not true of all studies or species (e.g. Babikian et al, 2017; Giacomin, Bryant, et al, 2019; Urbina & Glover, 2015) and there is a lack of consensus regarding the cost of ion regulation in fishes (Ern et al, 2014). Furthermore, the cost of maintaining ion balance in developing fish larvae whose ionoregulatory physiology differs dramatically from that of adults due to a lack of gills (cutaneous ionoregulation) and large surface area‐to‐volume ratios (Brauner & Rombough, 2012; Rombough, 2007) may be even lower than that estimated for adults (Parker et al, 2020).…”

Physiology and aquaculture: A review of ion and acid‐base regulation by the gills of fishes

Fish aquaculture facilities strive to maintain abiotic conditions that optimise somatic growth. Two physiological systems that are critically linked to environmental abiotic factors are ion and acid-base regulation. Given the detrimental effects of ionic and acid-base imbalances coupled with the potential energetic costs of ion and acid-base regulation, it is important to understand how changes in abiotic variables such as salinity, temperature and pH alter ionoregulatory and acid-base physiology. The gill is the predominant site of ion and acid-base regulation, two linked processes that are vital to the health of fishes. Most species maintain ion levels in the blood plasma within a narrow range, independent of external ion concentrations. In freshwater (FW), fishes must actively take up ions from their dilute environment to counteract passive ion losses, while in seawater (SW), ion excretion serves to counteract passive salt gain. Ion uptake (FW) and excretion (SW) are coordinated by different subtypes of ion-transporting cells (ionocytes) expressed in the gill epithelium. In this review, we discuss the function of FW and SW ionocytes in the movement of ions across the gill epithelium and address other features of the gill that are integral to ionoregulation.We also discuss the mechanisms of acid-base regulation by the gill, which is intimately related to ion regulation because it is coordinated by Na + -and Cl − -linked fluxes of acid (H + ) and base (HCO − 3 ) equivalents. These fundamental physiological principles are integral in understanding how fishes in aquaculture respond to relevant disturbances that may occur under culture conditions.
